Planting method of annual multi-crop fast-growing crops with vigorous growth period and seedling period interval switching

Abstract

This invention provides a method for planting multiple crops of fast-growing crops per year with alternating periods of vigorous growth and seedling stage. The method includes soil improvement in the planting area to ensure that the organic matter content in the soil is greater than or equal to a preset value, eliminating the need for tilling for two years; dividing the planting area into a first zone and a second zone, with a wheeled or tracked path between them; inhibiting crop growth in the first or second zone to alternate between vigorous growth and seedling stage crops; and applying fertilizer to the first or second zone, specifically in the following situations: applying fertilizer to the first or second zone after harvest; and / or applying fertilizer to the first or second zone during the seedling stage. This invention achieves alternating periods of vigorous growth and seedling stage crops on the same land by inhibiting crop growth in the first or second zone, thereby improving sunlight utilization. Furthermore, the wheeled or tracked path prevents damage to the root system during the vigorous growth or seedling stage.

Description

Technical Field

[0001] This invention relates to the field of crop cultivation technology, specifically to a method for planting fast-growing crops that alternates between the vigorous growth period and the seedling period, allowing for multiple crops per year. Background Technology

[0002] Fast-growing crops are becoming an important part of cash crops and are playing a significant role in improving farmers' living conditions both domestically and internationally. For example, giant reed grass, wheat straw, alfalfa, and golden forage grass have already demonstrated considerable value in fields such as fisheries, mushroom cultivation substrate, and cattle and sheep farming.

[0003] Traditional methods for growing fast-growing crops, such as giant reed in southern regions, allow for 4-6 harvests. However, after harvesting, the crop's leaf area is significantly reduced, meaning much sunlight doesn't reach the leaves. This still occupies planting land, preventing immediate reuse and resulting in inefficient use of sunlight during the period from harvest to the next seedling stage (approximately 1 / 3 to 1 / 2 of the growing cycle). Current technologies using greenhouse seedling cultivation can concentrate seed production before the warmer months, allowing for a month's earlier access to sunlight. However, this is often limited by the annual nature of the crop, resulting in limited improvement in overall sunlight utilization. Furthermore, while greenhouse cultivation can address temperature regulation and extend the growing season in northern or subtropical regions, it suffers from high construction costs and is difficult to promote. Moreover, for fast-growing crops with multiple annual harvests, the issue of low sunlight utilization after harvest remains unresolved.

[0004] Furthermore, when densely planted with fast-growing crops that are harvested multiple times a year, it is difficult to replace the base fertilizer in the soil, leading to weakened growth and reduced yield in the later stages of crop growth. Additionally, for tall, fast-growing crops such as giant reed grass, after harvesting, a certain degree of hardness remains on the soil surface from the stem diameter or root system. When harvesting or transport equipment passes over this stem diameter or root system, it can easily damage the remaining stem diameter / root system, affecting the normal germination and growth of the next crop. Furthermore, the stem diameter or root system can easily puncture the tires of the harvesting or transport equipment, increasing the failure rate and safety hazards of mechanical operations.

[0005] Therefore, how to improve the utilization rate of sunlight during the planting of fast-growing crops, solve the difficulty of replacing base fertilizer under dense planting conditions for many years, and achieve safe and efficient mechanical harvesting and passage are technical problems that urgently need to be solved. Summary of the Invention

[0006] This invention provides a planting method for fast-growing crops that alternates between the vigorous growth period and the seedling period, thereby solving the technical problems of how to improve the utilization rate of sunlight during the planting of fast-growing crops, the difficulty of replacing base fertilizer under dense planting conditions over many years, and the achievement of safe and efficient mechanical harvesting and passage.

[0007] This invention provides a method for planting fast-growing crops that alternate between the vigorous growth period and the seedling period, including: The soil in the planting area is improved to ensure that the organic matter content in the soil of the planting area is greater than or equal to a preset value, so that the planting area does not need to be tilled for at least two years. The planting area is divided into sections, each including at least a first section and a second section, with a wheel or track travel path between the first section and the second section. Growth inhibition is applied to crops in the first or second zone, wherein the growth inhibition is used to separate crops in the vigorous growth stage from crops in the seedling stage in the first and second zones. Fertilizer is applied to the first or second zone when the first or second zone has been harvested, or when the first or second zone is in the seedling stage.

[0008] Optionally, the growth inhibition is achieved in one or more of the following ways: Harvesting; late planting; application of growth inhibitors, wherein the growth inhibitors are used to inhibit the growth of fast-growing crops planted in the first or second zone, and the growth inhibitors include at least one of the following: Paclobutrazol, chlormequat chloride, mepiquat chloride, dextrin, uniconazole, ethylene, carbon dioxide, nitric oxide.

[0009] Optionally, the fertilizer supplement includes one or more of liquid fertilizer and solid fertilizer; The liquid fertilizer includes one or more of inorganic liquid fertilizer, organic liquid fertilizer, and liquid germination promoter; The solid fertilizer includes one or more of inorganic solid fertilizer, organic solid fertilizer, and solid germination promoter.

[0010] Optionally, the organic liquid fertilizer and the organic solid fertilizer contain humic acid and / or humate salts.

[0011] Optionally, the wheel or track travel path is used to provide the necessary path for the wheels or tracks of the harvesting device and the transport device to travel.

[0012] Optionally, harvesting and transporting devices are used to harvest crops in the first or second zone, each of which includes at least one planting unit, and the harvesting is carried out in one or more of the following ways: The harvesting device and the transport device are the same equipment; The harvesting device and the transport device travel in a front-to-back sequence within the same planting unit, with the harvesting device harvesting first and the transport device receiving second. The harvesting device and the transport device operate independently in different planting units.

[0013] Optionally, the harvesting device is a single-zone harvesting device or an interval-zone harvesting device; The single-zone harvesting device refers to a harvesting platform that is continuously arranged in the harvesting width direction of the harvesting device; the interval-zone harvesting device refers to a harvesting platform that is spaced apart in the harvesting width direction of the harvesting device.

[0014] Optionally, it also includes: providing a covering over the area of ​​the roots of the fast-growing crop retained after harvesting to prevent the roots of the fast-growing crop retained after harvesting from freezing in winter; The covering includes one or more of the following; One or more layers of agricultural mulch film; one or more layers of bubble wrap; straw; organic fertilizer; arched sheds and soil.

[0015] Optionally, it also includes: supplementing the first zone and / or the second zone with carbon dioxide.

[0016] Optionally, when the first zone and / or the second zone adopts open planting, a device to reduce carbon dioxide leakage is installed in the first zone and / or the second zone; The device for reducing carbon dioxide leakage includes columns and an airtight plate or membrane between the columns.

[0017] Optionally, the soil improvement material used in the soil improvement includes one or more organic matter with different degradation cycles, and the organic matter with different degradation cycles includes at least one organic matter with a degradation cycle greater than or equal to 2 years.

[0018] Optionally, the planting method is applied in a greenhouse planting environment.

[0019] Compared with the prior art, the present invention has the following advantages: This invention provides a method for planting multiple crops of fast-growing crops per year with alternating periods of vigorous growth and seedling stage, comprising: improving the soil of the planting area to ensure that the organic matter content in the soil of the planting area is greater than or equal to a preset value so that the planting area does not need to be tilled for at least two years; dividing the planting area into zones, the planting area including at least a first zone and a second zone, with a wheel or track travel path between the first zone and the second zone; inhibiting the growth of crops in the first zone or the second zone, the growth inhibition being used to alternate between vigorous growth crops and seedling stage crops in the first zone and the second zone; and applying fertilizer to the first zone or the second zone, the fertilization being carried out in the following situations: applying fertilizer to the first zone or the second zone after harvest; and / or applying fertilizer to the first zone or the second zone in the seedling stage.

[0020] This invention can be understood as follows: by improving the soil in the planting area, the organic matter content of the soil is ensured to be greater than or equal to a preset value, thus guaranteeing the supply of base fertilizer for fast-growing crops over many years. Furthermore, the planting area is divided into a first zone and a second zone, with a wheeled or tracked path between the two zones. This means that the harvesting and transport devices have dedicated paths for their wheels or tracks, allowing them to enter the first or second zone for operation without damaging the roots of crops in their vigorous growth or seedling stages. Simultaneously, growth inhibition is applied to crops within the first or second zone. This growth inhibition separates vigorous growth crops from seedling crops in the first and second zones, thereby improving the crop's sunlight utilization rate. Attached Figure Description

Therefore, they should not be construed as limitations on this invention.

[0037] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0038] Taking fast-growing crops that are harvested every 60 days (such as giant reed grass) as an example, Figures 1a to 1d and Figures 2a-2b As shown, fast-growing crops (which can be simply referred to as crops) include the seedling stage, the vigorous growth stage, and the harvestable stage. The vigorous growth stage includes the large seedling stage (day 30-day 45, greater than or equal to 30 days and less than 45 days, and the following time ranges are all values ​​with the first closed and the second open) and the strong seedling stage (day 45-day 60, greater than or equal to 45 days and less than 60 days); the harvestable stage (day 60); the seedling stage includes the post-harvest / budding stage (day 0-day 15, greater than or equal to 0 days and less than 15 days) and the small seedling stage (day 15-day 30, greater than or equal to 15 days and less than 30 days).

[0039] like Figure 1a As shown, for ease of explanation in implementing this invention, the growth cycle is simply divided into stages: For crops in the seedling stage (after harvest / budding stage), such as crops with a status indicator of 1000 on day 0, specifically crop 1001 (day 0, label 1), crop 1002 (day 0, label 2), crop 1003 (day 0, label 3), crop 1004 (day 0, label 4), and crop 1005 (day 0, label 5). For crops in the vigorous growth stage (large seedling stage), such as crops with a status indicator of 1200 on day 30, specifically crop 1201 (day 30, label 1), crop 1202 (day 30, label 2), crop 1203 (day 30, label 3), crop 1204 (day 30, label 4), and crop 1205 (day 30, label 5). Crops that have grown to maturity and are ready for harvest, such as crops marked as 1400 on day 60 (specifically, crop 1401 marked as day 60, crop 1402 marked as day 60, crop 1403 marked as day 60, crop 1404 marked as day 60, and crop 1405 marked as day 60), will return to the seedling stage after harvest and enter the next cycle of fast-growing crops.

[0040] The above description of the seedling, vigorous growth, and maturity stages of crops in days serves as an example to illustrate the switching logic between different growth stages. In practice, this can be adjusted based on crop variety, climate conditions, and cultivation conditions. Furthermore, as... Figure 1aAs shown, to more accurately represent different growth stages of crops, intermediate states of fast-growing crops from the post-harvest / seedling stage to the vigorous growth stage are marked. For example, the seedling stage, i.e., crops with a status of 1100 on day 15, specifically as crop 1101 (number 1 on day 15), crop 1102 (number 2 on day 15), crop 1103 (number 3 on day 15), crop 1104 (number 4 on day 15), and crop 1105 (number 5 on day 15). And intermediate states from the vigorous growth stage to maturity and ready for harvest, such as the robust seedling stage of the vigorous growth stage, i.e., crops with a status of 1300 on day 45, specifically as crop 1301 (number 1 on day 45), crop 1302 (number 2 on day 45), crop 1303 (number 3 on day 45), crop 1304 (number 4 on day 45), and crop 1305 (number 5 on day 45).

[0041] like Figure 1b As shown, crop height and solar utilization rate vary with the number of days during the periods of 0-15 days, 15-30 days, 30-45 days, and 45-60 days. To simplify the calculation, a simplification is made based on the actual growth of the crop. The status indicators for the average growth status of the crop during the periods of 0-15 days (1500), 15-30 days (1600), 30-45 days (1700), and 45-60 days (1800) are selected as the average growth status for 0-15 days, 15-30 days, 30-45 days, and 45-60 days, respectively.

[0042] For ease of calculation, crops with an average growth status of 1500 from day 0 to day 15 are designated as follows: fast-growing crop 1501 (average growth status 1), fast-growing crop 1502 (average growth status 2), fast-growing crop 1503 (average growth status 3), fast-growing crop 1504 (average growth status 4), and fast-growing crop 1505 (average growth status 5). Crops with an average growth status of 1600 from day 15 to day 30 include, specifically, fast-growing crop 1601 (average growth status 1), fast-growing crop 1602 (average growth status 2), fast-growing crop 1603 (average growth status 3), fast-growing crop 1604 (average growth status 4), and fast-growing crop 1605 (average growth status 5). Crops with an average growth status of 1700 from day 30 to day 45 include, specifically, fast-growing crop 1701 (average growth status 1), fast-growing crop 1702 (average growth status 2), fast-growing crop 1703 (average growth status 3), fast-growing crop 1704 (average growth status 4), and fast-growing crop 1705 (average growth status 5). Crops with an average growth status of 1800 from day 45 to 60 include, specifically, fast-growing crop 1801 (average growth status 1), fast-growing crop 1802 (average growth status 2), fast-growing crop 1803 (average growth status 3), fast-growing crop 1804 (average growth status 4), and fast-growing crop 1805 (average growth status 5).

[0043] Solar energy utilization efficiency can be calculated using a derivative formula of the Beer-Lambert law. The most commonly used formula for calculating solar energy utilization efficiency (interception rate) is: Where: I (Interception): Light interception rate (range 0-1, that is, 0%-100%).

[0044] LAI (Leaf Area Index): The leaf area index refers to the ratio of the total area of ​​plant leaves per unit land area to the total land area.

[0045] k (Extinction Coefficient): Extinction coefficient, a parameter reflecting leaf angle and crop type.

[0046] e: The base of the natural logarithm.

[0047] To calculate the utilization rate using the above formula, the following two values ​​need to be determined: Leaf area index (LAI): The decisive factor, which is the variable that varies the most with the number of growing days.

[0048] 0-15 days (seedling stage): Newly sprouted or with cotyledons unfolded, the leaves are extremely small, covering almost no ground area. At this stage, LAI ≈ 0. Substituting into the formula: =1-1=0.

[0049] 15-30 days (seedling stage): Leaves begin to grow, but the canopy has not yet closed (leaves do not completely cover the ground). Assuming LAI reaches approximately 0.8-1.2, substituting into the formula: Assuming k=0.7 (for general crops) and LAI=1, then I= =1- It is close to 50%.

[0050] 30-45 days (large seedling stage) and 45-60 days (vigorous seedling stage): The plants are lush, with layers of leaves completely covering the ground. Typically, when LAI > 3 or 4, sunlight has difficulty penetrating the ground. Substituting into the formula: Assuming k = 0.7 (for general crops) and LAI = 4, then... =1- 100%.

[0051] Extinction coefficient (k): A crop characteristic parameter that depends on the leaf angle and planting density. Horizontal leaf crops have a larger k value (approximately 0.7-1.0), making them more likely to block sunlight and thus increasing their utilization rate more quickly.

[0052] To reduce model complexity and facilitate engineering calculations, based on the average growth of stems and leaves at different growth stages of the crop, the average solar utilization rates of the above-mentioned crops at 0-15 days, 15-30 days, 30-45 days, and 45-60 days are simplified to 0% (representing extremely low utilization, before germination or with very small buds, utilization is negligible, and the average percentage of sunlight falling on the leaves in the planting area is simplified to 0%), 50% (stems and leaves are initially grown, and the average percentage of sunlight falling on the leaves in the planting area is approximately 50%), 100% (stems and leaves are lush, and the average percentage of sunlight falling on the leaves in the planting area is close to 100%), and 100% (stems and leaves are lush, and the average percentage of sunlight falling on the leaves in the planting area is close to 100%). The utilization rate refers to the proportion of luminous flux falling on the crop leaves when sunlight is projected onto the planting area, relative to the total incident luminous flux in the planting area. The time ranges, as mentioned above, are all closed-end ranges followed by open-end ranges.

[0053] like Figure 1e As shown, this invention provides a method for planting fast-growing crops that alternate between the vigorous growth period and the seedling period, allowing for multiple crops per year, including: S101: Improve the soil in the planting area to ensure that the organic matter content in the soil of the planting area is greater than or equal to a preset value, so that the planting area does not need to be tilled for at least two years. Figure 2a As shown, soil improvement in the planting area involves using mechanical equipment such as rotary tillers and combined tillage machines to plow the land. During plowing, organic matter is mixed into the soil, and the organic matter content is greater than or equal to a preset value. This preset value can be determined by the type of fast-growing crop and the area of ​​the planting area. This improves soil porosity and aggregate formation, ensuring that the organic matter content is high enough to allow for continuous planting for more than two years without the need for complete plowing. Through soil improvement, fast-growing crops that are grown multiple times a year can still receive a continuous supply of base fertilizer under subsequent planting and harvesting conditions, thereby mitigating the problem of weak growth in later stages caused by long-term planting.

[0054] S102: The planting area is divided into zones, each including at least a first zone and a second zone, with a wheel or track travel path between the first zone and the second zone. By dividing the planting area, zoned planting can be achieved, and a wheel or track travel path 2200 is provided between the first zone 2000 and the second zone 2100. Figures 2a-2b , Figures 3a-3c as well as Figure 5b As shown, the planting area can be divided into a first zone 2000 and a second zone 2100. The first zone 2000 and the second zone 2100 are arranged in strips, such as each strip of the first zone 2000 and the second zone 2100 having a strip width of 2 meters. A wheel or track travel path 2200 is included between the first zone 2000 and the second zone 2100 so that mechanical equipment can enter the corresponding planting area along the wheel or track travel path 2200 to carry out operations such as harvesting and fertilizing, without damaging the root system in the vigorous growth stage or seedling stage.

[0055] Since the distance between vehicles is approximately two meters, the robotic arm of the machinery may be about 2 meters wide, or it may be about 6 meters, 10 meters, or even wider. Therefore, for a planting area of ​​2 meters, such as for tall crops, using a 2-meter-wide robotic arm configuration, the first zone (2000), the wheeled or tracked path (2200), and the second zone (2100) can be distributed sequentially. Figure 2aAs shown, wheel or track travel paths 2200 are sequentially distributed between the first zone 2000 and the second zone 2100. For short-stalked crops, such as alfalfa, which is about 1 meter tall, the width of adjacent zones is about 1 meter. In this case, one wheel or track travel path is sufficient for two first or second zones. Drainage ditches should be constructed between adjacent first and second zones. That is to say, one wheel or track travel path can be set between multiple first and second zones. For example, for the width of the robotic arm of large machinery, such as a robotic arm about 10 meters wide, it can cover five 2-meter-wide first and second zones. One set of wheel or track travel paths (such as 3, which can meet the needs of machinery traveling in the first and second zones) can cover the needs of multiple first and second zones (such as 3 first and 3 second zones, for a total of 6). There are cases where it is not necessary to set wheel or track travel paths between the first and second zones; drainage ditches can be constructed. Alternatively, all zones can be made into wheel or track travel paths. In actual practice, the size difference between the two is not significant for planting areas of about 2 meters wide, so no restriction is made. The path for wheels or tracks can be hardened, compacted, or a combination of drainage and vehicle movement.

[0056] It should be noted that for soil improvement, it can be done only in the planting area (zone 1 and zone 2), or the entire planting area and the wheel or track travel path can be improved, with compaction of the wheel or track travel path as needed. Since fast-growing crops that are grown multiple times a year are mostly tall crops with hard stalks, and subsequent sprouting often occurs on the 5-10cm diameter of the stalk or root system left during harvest, if wheel or track travel paths are not reserved in the planting area, machinery will run over the leftover stalk or root system. This will not only make it difficult for the next crop to sprout, but also risk puncturing the machinery's tires. Therefore, reserving wheel or track travel paths in zoned planting allows for safe and efficient mechanical harvesting and passage.

[0057] S103: Growth inhibition is applied to crops within the first or second zone, wherein the growth inhibition is used to separate crops in their vigorous growth stage from those in their seedling stage in the first and second zones. For example... Figure 2a As shown, taking a fast-growing crop that can be harvested every 60 days (such as giant Napier grass) as an example, the growth status during the 0-15 day period is monitored. With the help of growth inhibition, if the crop in Zone 2100 is harvested, the fast-growing crop with an average growth status of 1700 during the 30-45 day period is planted in Zone 12000, while the fast-growing crop with an average growth status of 1500 during the 0-15 day period is planted in Zone 2100. The growth cycle of the crops in Zone 12000 and Zone 2100 differs by 30 days, achieving the effect of alternating between crops in their vigorous growth stage and crops in their seedling stage when planting crops in different zones.

[0058] S104: Apply fertilizer to the first or second zone. This application of fertilizer is performed when: the first or second zone has been harvested; and / or when the first or second zone is in the seedling stage. Furthermore, S104: applying fertilizer to the first or second zone can be based on the above-described S103: growth inhibition of the crops in the first or second zone, where the growth inhibition is used to achieve a separation between crops in their vigorous growth phase and seedling stage in the first and second zones, followed by fertilization. Alternatively, it can be performed concurrently with the aforementioned growth inhibition. This effectively achieves superior growth under the premise of a separation between crops in their vigorous growth phase and seedling stage (e.g., a 30-day growth interval).

[0059] like Figure 2a As shown, during days 0-15, in zone 2100, after harvesting, there were no seedlings, or the seedlings were still very small (e.g. Figure 1a As shown in the Day 0 state, whether applying liquid fertilizer or solid fertilizer, it is easy to apply to the soil and will not be blocked by the leaves, allowing for relatively even application.

[0060] In this way, the vigorous growth stage and seedling stage of crops can be alternated on the same land, making full use of sunlight. For example... Figure 2aAs shown, during days 0-15, crop 2000 in Zone 1 is in its vigorous seedling stage (specifically, crops with an average growth status of 1700 during days 30-45), while crop 2100 in Zone 2 is in its post-harvest / budding seedling stage (specifically, crops with an average growth status of 1500 during days 0-15). During days 15-30, crop 2000 in Zone 1 is in its vigorous seedling stage (specifically, crops with an average growth status of 1800 during days 45-60), while crop 2100 in Zone 2 is in its seedling stage (specifically, crops with an average growth status of 1600 during days 15-30), and crop 2000 in Zone 1 enters the harvest-ready stage. On day 30, crop 2000 in Zone 1 is harvested, and crop 2100 in Zone 2 enters its vigorous stage, switching between the vigorous stage and the seedling stage. Thus, from day 30 to 45, the 2000 crops in Zone 1 are in the post-harvest / budding stage of the seedling stage, specifically those with an average growth status indicator of 1500 from day 0 to 15. The 2100 crops in Zone 2 are in the vigorous seedling stage, specifically those with an average growth status indicator of 1700 from day 30 to 45. From day 45 to 60, the 2000 crops in Zone 1 are in the small seedling stage, specifically those with an average growth status indicator of 1600 from day 15 to 30. The 2100 crops in Zone 2 are in the vigorous seedling stage, specifically those with an average growth status indicator of 1800 from day 45 to 60. The 2100 crops in Zone 2 also enter the harvest-ready stage. On day 60, the 2100 crops in Zone 2 are harvested, and the 2000 crops in Zone 1 enter the vigorous stage, switching between the vigorous stage and the seedling stage. This process is repeated to alternate between the vigorous growth stage and the seedling stage of crops on the same land, making full use of sunlight. This increases the total annual yield of fast-growing crops that can be harvested multiple times a year.

[0061] Specifically, taking fast-growing crops that are harvested every 60 days (such as giant reed grass) as an example, Figure 1c Place Compared with the traditional planting model (harvest cycle of 60 days), a simple calculation and analysis of sunlight utilization rate was performed on the first zone 2000 and the second zone 2100: First, the average sunlight utilization rate of the first zone 2000 and the second zone 2100 in each time period of 0-15 days, 15-30 days, 30-45 days and 45-60 days was calculated, and then the comprehensive sunlight utilization rate in the growth cycle was obtained by weighting according to the proportion of each time period.

[0062] like Figure 1cAs shown, during days 0-15, the crops in Zone 1 (2000) and Zone 2 (2100) have an average growth status indicator of 1500. During days 15-30, the crops in Zone 1 (2000) and Zone 2 (2100) have an average growth status indicator of 1600. During days 30-45, the crops in Zone 1 (2000) and Zone 2 (2100) have an average growth status indicator of 1700. During days 45-60, the crops in Zone 1 (2000) and Zone 2 (2100) have an average growth status indicator of 1800. Furthermore, a ditch 2300 is provided between adjacent Zones 1 (2000) and Zone 2 (2100).

[0063] like Figure 1d As shown, during the process of the sun rising in the east (E) and setting in the west (W) from day 3000, taking day 0-15 as an example, the fast-growing crops with an average growth status of 1500 on day 0-15 are planted in Zone 1 2000 and Zone 2 2100. Specifically, the crops planted in Zone 1 2000 on the left are: fast-growing crop 1506 with an average growth status of 6 on day 0-15, fast-growing crop 1507 with an average growth status of 7 on day 0-15, fast-growing crop 1508 with an average growth status of 8 on day 0-15, fast-growing crop 1509 with an average growth status of 9 on day 0-15, and fast-growing crop 1510 with an average growth status of 10 on day 0-15. The crops planted in Zone 2100 are: fast-growing crop 1511 (average growth status number 11 for days 0-15), fast-growing crop 1512 (average growth status number 12 for days 0-15), fast-growing crop 1513 (average growth status number 13 for days 0-15), fast-growing crop 1514 (average growth status number 14 for days 0-15), and fast-growing crop 1515 (average growth status number 15 for days 0-15). The crops planted in Zone 12000 on the right are: fast-growing crop 1516 (average growth status number 16 for days 0-15), fast-growing crop 1517 (average growth status number 17 for days 0-15), fast-growing crop 1518 (average growth status number 18 for days 0-15), fast-growing crop 1519 (average growth status number 19 for days 0-15), and fast-growing crop 1520 (average growth status number 20 for days 0-15).

[0064] In Zone 1 (2000) and Zone 2 (2100), the fast-growing crops with an average growth status of 1600 after 15-30 days are planted. Specifically, the crops planted in Zone 1 (2000) on the left are: fast-growing crop 1606 with an average growth status of 6 after 15-30 days, fast-growing crop 1607 with an average growth status of 7 after 15-30 days, fast-growing crop 1608 with an average growth status of 8 after 15-30 days, fast-growing crop 1609 with an average growth status of 9 after 15-30 days, and fast-growing crop 1610 with an average growth status of 10 after 15-30 days. The crops planted in Zone 2100 are: fast-growing crop 1611 with an average growth status of 11 from day 15 to 30, fast-growing crop 1612 with an average growth status of 12 from day 15 to 30, fast-growing crop 1613 with an average growth status of 13 from day 15 to 30, fast-growing crop 1614 with an average growth status of 14 from day 15 to 30, and fast-growing crop 1615 with an average growth status of 15 from day 15 to 30. The crops planted in Zone 1, 2000 on the right are: fast-growing crop 1616 (average growth status number 16 from day 15 to day 30), fast-growing crop 1617 (average growth status number 17 from day 15 to day 30), fast-growing crop 1618 (average growth status number 18 from day 15 to day 30), fast-growing crop 1619 (average growth status number 19 from day 15 to day 30), and fast-growing crop 1620 (average growth status number 20 from day 15 to day 30).

[0065] In Zone 1 (2000) and Zone 2 (2100), the fast-growing crops with an average growth status of 1700 after 30-45 days are planted. Specifically, the crops planted in Zone 1 (2000) on the left are: fast-growing crop 1706 with an average growth status of 6 after 30-45 days, fast-growing crop 1707 with an average growth status of 7 after 30-45 days, fast-growing crop 1708 with an average growth status of 8 after 30-45 days, fast-growing crop 1709 with an average growth status of 9 after 30-45 days, and fast-growing crop 1710 with an average growth status of 10 after 30-45 days. The crops planted in Zone 2100 are: fast-growing crop 1711 with an average growth status of 11 from day 30 to 45, fast-growing crop 1712 with an average growth status of 12 from day 30 to 45, fast-growing crop 1713 with an average growth status of 13 from day 30 to 45, fast-growing crop 1714 with an average growth status of 14 from day 30 to 45, and fast-growing crop 1715 with an average growth status of 15 from day 30 to 45. The crops planted in Zone 1, 2000 on the right are: fast-growing crop 1716 with an average growth status of 16 from day 30 to 45, fast-growing crop 1717 with an average growth status of 17 from day 30 to 45, fast-growing crop 1718 with an average growth status of 18 from day 30 to 45, fast-growing crop 1719 with an average growth status of 19 from day 30 to 45, and fast-growing crop 1720 with an average growth status of 20 from day 30 to 45.

[0066] In Zone 1 (2000) and Zone 2 (2100), fast-growing crops with an average growth status of 1800 on days 45-60 are planted. Specifically, the crops planted in Zone 1 (2000) on the left are: fast-growing crop 1806 with an average growth status of 6 on days 45-60, fast-growing crop 1807 with an average growth status of 7 on days 45-60, fast-growing crop 1808 with an average growth status of 8 on days 45-60, fast-growing crop 1809 with an average growth status of 9 on days 45-60, and fast-growing crop 1810 with an average growth status of 10 on days 45-60. The crops planted in Zone 2100 are: fast-growing crop 1811 with an average growth status of 11 from day 45 to 60, fast-growing crop 1812 with an average growth status of 12 from day 45 to 60, fast-growing crop 1813 with an average growth status of 13 from day 45 to 60, fast-growing crop 1814 with an average growth status of 14 from day 45 to 60, and fast-growing crop 1815 with an average growth status of 15 from day 45 to 60. The crops planted in Zone 1, 2000 on the right are: fast-growing crop 1816 with an average growth status of 16 from day 45 to 60, fast-growing crop 1817 with an average growth status of 17 from day 45 to 60, fast-growing crop 1818 with an average growth status of 18 from day 45 to 60, fast-growing crop 1819 with an average growth status of 19 from day 45 to 60, and fast-growing crop 1820 with an average growth status of 20 from day 45 to 60.

[0067] The fast-growing crops planted in Zone 1 (2000) and Zone 2 (2100) were unaffected by lateral sunlight (in reality, there are far more than three planting zones, usually 30 or even 300 zones connected together), and their growth was identical. The average sunlight utilization rates of Zone 1 (2000) and Zone 2 (2100) at different time periods are shown below: Then, the comprehensive utilization rate of sunlight during the growth cycle is obtained by weighting the proportion of each time period, as shown below: The comprehensive utilization rate of sunlight is: When adopting such Figure 2a When the planting pattern shown alternates between the vigorous growth period and the seedling stage (harvesting cycle of 60 days, with mature areas harvested every 30 days, and the repeat cycle can be calculated as 30 days), the sunlight utilization rate of Zone 1 (2000) and Zone 2 (2100) is calculated and analyzed: First, the average sunlight utilization rate of Zone 1 (2000) and Zone 2 (2100) in each time period from 0 to 15 days and from 15 to 30 days is calculated, and then the comprehensive sunlight utilization rate in the growth cycle is obtained by weighting according to the proportion of each time period.

[0068] like Figure 2bAs shown, in the simplified calculation mode, during days 0-15, the fast-growing crops planted in the first zone 2000 on the left are: fast-growing crop 1721 with average growth status number 21 for days 30-45, fast-growing crop 1722 with average growth status number 22 for days 30-45, fast-growing crop 1723 with average growth status number 23 for days 30-45, fast-growing crop 1724 with average growth status number 24 for days 30-45, and fast-growing crop 1725 with average growth status number 25 for days 30-45. These crops are higher than those in the adjacent second zone and will not be shaded by neighboring crops. Therefore, the sunlight that should have reached this zone (compared to...) Figure 1d The crops will still receive adequate sunlight, and the utilization rate will not change to 100%. The fast-growing crops planted in Zone 2100 are: fast-growing crop 1521 with an average growth status of 21 for 0-15 days, fast-growing crop 1522 with an average growth status of 22 for 0-15 days, fast-growing crop 1523 with an average growth status of 23 for 0-15 days, fast-growing crop 1524 with an average growth status of 24 for 0-15 days, and fast-growing crop 1525 with an average growth status of 25 for 0-15 days. The fast-growing crops planted in the first zone on the right are: 1726 (average growth status number 26 for days 30-45), 1727 (average growth status number 27 for days 30-45), 1728 (average growth status number 28 for days 30-45), 1729 (average growth status number 29 for days 30-45), and 1730 (average growth status number 30 for days 30-45). Because the second zone 2100 is located between the two first zones 2000, and is shaded by the adjacent first zones 2000 on the left and right, the sunlight that should have reached this zone (in contrast) is limited. Figure 1d The effective utilization rate will be affected by the shading of adjacent plots and needs to be recalculated.

[0069] The sunlight utilization rate of Zone 2100 was analyzed. For the example, the crop was a tall, fast-growing crop (such as giant Napier grass, assuming a height of about 2m at harvest). The growth cycle of Zone 1 2000 and Zone 2100 was 30 days apart, and the calculation and analysis were performed with the crop in Zone 2100 being 1m shorter than the crop in Zone 1 2000.

[0070] like Figure 2bAs shown, during the process of the sun rising in the east (E) and setting in the west (W) from day 0 to 15 (left image), when the sunlight shines within the range of 0-27° (e.g., sunlight angle 27° illuminating ray 3101), the sunlight that should have shone on the second zone is instead utilized by the fast-growing crops (large seedlings, 100% utilization rate) in the first zone (2000) on the right. Simply put, the fast-growing crops in the first zone (2000) on the right have grown 1 meter taller than their ground-level counterparts, blocking and utilizing the sunlight in the second zone. When the sunlight shines within the range of 153-180° (e.g., sunlight angle 153° illuminating ray 3102), the sunlight is utilized by the fast-growing crops (large seedlings, 100% utilization rate) in the first zone (2000) on the left. Therefore, during this period, the sunlight utilization rate in the second zone (2100) is 100%. This can be understood as the shadow area 3201 (area 1) being utilized by the crops in the first zone on both the left and right sides of the first zone. When sunlight shines within the range of 27-153°, taking the diagram on the right as an example from day 0-15, and using a sunlight incident angle of 50° as an example, if sunlight shines on ray 3103 at a 50° angle, the sunlight area 3301 is 0% because the sunlight shines on fast-growing crop 1521 (average growth status 21), fast-growing crop 1522 (average growth status 22), and fast-growing crop 1523 (average growth status 23) from day 0-15 (post-harvest / young shoot stage crops, utilization rate 0%). The shaded area of ​​No. 2, 3202, has a sunlight utilization rate of 100% because sunlight is utilized by crop No. 2000 in Zone 1 on the right. Integrating the sunlight area and shaded area within the 27-153° range of sunlight, the ratio of sunlight area (0% sunlight utilization rate) to shaded area (100% sunlight utilization rate) is 1:1. Therefore, the sunlight utilization rate of No. 2, 2100, within the 0-180° range of sunlight exposure on days 0-15 is calculated as follows: Involving the sunlight utilization rate of plot 2100 in Zone 2: During days 15-30, with Figure 2b Taking the left image as an example (days 15-30), since the first zone on the left is 2000... The fast-growing crops planted were: 1821 (average growth status number 21 for days 45-60), 1822 (average growth status number 22 for days 45-60), 1823 (average growth status number 23 for days 45-60), 1824 (average growth status number 24 for days 45-60), and 1825 (average growth status number 25 for days 45-60) (seedling stage crops, 100% utilization rate). These crops were superior to those in the adjacent second zone and were not affected by shading from the adjacent second zone. Therefore, the sunlight that should have been irradiated by this first zone (compared to...) Figure 1d The crops will still receive adequate sunlight, and the utilization rate will remain unchanged at 100%. The fast-growing crops planted in Zone 2100 are: fast-growing crop 1621 (average growth status number 21 for days 15-30), fast-growing crop 1622 (average growth status number 22 for days 15-30), fast-growing crop 1623 (average growth status number 23 for days 15-30), fast-growing crop 1624 (average growth status number 24 for days 15-30), and fast-growing crop 1625 (average growth status number 25 for days 15-30) (small seedling stage crops, utilization rate 50%). The fast-growing crops planted in Zone 1 (2000) on the right are: 1826 (average growth status number 26 from day 45-60), 1827 (average growth status number 27 from day 45-60), 1828 (average growth status number 28 from day 45-60), 1829 (average growth status number 29 from day 45-60), and 1830 (average growth status number 30 from day 45-60) (strong seedling stage, utilization rate 100%). Similar to the crops in Zone 1 on the left, the utilization rate remains 100%. Zone 2 is affected by the shading from the fast-growing crops (strong seedling stage) in Zone 1 (2000) on both the left and right sides, so the effective utilization rate needs to be recalculated. This can be understood as the sunlight in the shaded area of ​​Zone 3 (3203) being utilized by the crops in Zone 1 on both the left and right sides. Similarly, assuming the crops in Zone 2100 are 1m shorter than those in Zone 12000, the calculation and analysis show that when sunlight shines within the range of 0-27° (e.g., sunlight angle of 27° irradiation ray 3104), the sunlight will be utilized by the fast-growing crops in Zone 12000 on the right. When sunlight shines within the range of 153-180° (e.g., sunlight angle of 153° irradiation ray 3105), the sunlight will be utilized by the fast-growing crops in Zone 12000 on the left. Therefore, the sunlight utilization rate is 100% during this period.

[0071] When sunlight shines within the range of 27-153°, such as Figure 2bAs shown in the right figure for days 15-30, taking a sunlight incident angle of 50° as an example, when sunlight shines on ray 3106 at a 50° angle, the sunlight area 3302 in zone 2 has a sunlight utilization rate of 50% because it shines on fast-growing crops 1621 (average growth status 21), 1622 (average growth status 22), and 1623 (average growth status 23) during days 15-30. The sunlight utilization rate of the shadow area 3204 in zone 4 is 100% because the sunlight is utilized by crop 2000 in zone 1 on the right. Integrating the sunlight area and shadow area within the sunlight range of 27-153°, the ratio of sunlight area (50% sunlight utilization rate) to shadow area (100% sunlight utilization rate) is 1:1. Therefore, the sunlight utilization rate of zone 2100 in zone 2 within the 0-180° range during days 15-30 is calculated as follows: The sunlight utilization rate of plot 2100 in Zone 2 is: Therefore, when adopting a planting pattern that alternates between the vigorous growth period and the seedling period, the intervals should be from day 0-15 and day 15-30. The average solar utilization rates for Zone 1 (2000) and Zone 2 (2100) are shown below: Then, the comprehensive utilization rate of sunlight during the growth cycle is obtained by weighting the proportion of each time period, as shown below: The comprehensive utilization rate of sunlight is: = Therefore, the planting model that alternates between the vigorous growth period and the seedling period improves sunlight utilization compared to the traditional planting model: This invention's planting method, which alternates between the vigorous growth period and the seedling stage for multiple crops per year, can improve overall solar energy utilization by up to 39% compared to traditional methods. It should be noted that since the seedling stage crops grow sparsely, it is assumed that the seedlings receive sufficient sunlight under this invention's method. Thus, this planting method, which alternates between the vigorous growth period and the seedling stage, means that after harvest, the vigorous growth period crops and the seedling stage crops grow alternately, but the first and second zones are switched and repeatedly alternated, resulting in a significant improvement in overall solar energy utilization (up to 39%) and an increase in the total annual yield of multiple crops per year.

[0072] The planting method of the present invention includes a growth inhibition method, which inhibits growth in a first zone 2000 or a second zone 2100 that needs to be maintained in the seedling stage, so as to achieve intercropping of vigorous crops and seedling crops. The growth inhibition employs one or more of the following methods: Harvesting; late planting; use of growth inhibitors, the growth inhibitors being used to inhibit the growth of fast-growing crops planted in the first zone 2000 or the second zone 2100, the growth inhibitors including at least one of the following: paclobutrazol, chlormequat chloride, mepiquat chloride, dextrin, uniconazole, ethylene, carbon dioxide, nitric oxide.

[0073] During the alternation of planting between the vigorous growth stage and the seedling stage, the vigorous growth stage crops that have reached the harvestable stage can be harvested to achieve this transition. For the first planting, a later planting method can be used, such as... Figure 2a The second zone 2100 crops planted on days 0-15 are planted 30 days later than the first zone 2000 crops, or for some crops planted at the same time (such as...). Figure 2a Harvesting the second-phase crop (days 0-15) around day 30 (halfway through the crop's growth cycle) allows for intercropping of vigorous-stage and seedling-stage crops, achieving optimal results. Figure 2a Status from day 0 to day 15.

[0074] For crops that need to overwinter in the north, there is the issue of preparing for winter, and after spring arrives, the following year, it is still necessary to alternate planting during the vigorous growth period and the seedling stage. On the one hand, such as Figure 2a During days 0-15, crops in Zone 1 (2000 plants) and Zone 2 (2100 plants) grow simultaneously. However, crops in Zone 2 (2100 plants) are harvested around day 30 (halfway through the growth cycle), returning to the starting point. Figure 2a The state of affairs from day 0 to 15. On the other hand, such as... Figure 2a For the first 2000 crops in Zone 1 (days 0-15), mulching or other methods of insulation can be used to encourage germination and promote growth to the seedling stage. Then, the second 2100 crops can begin to grow and enter the next growth phase. Figure 2a The 0-15 day stage. In practical implementation, for multi-crop crops that need to be planted over winter, the growth cycle is slightly longer due to the lower temperatures in spring and winter, resulting in slower growth. Crops in zones 2000 and 2100 can be allowed to germinate and reach the seedling stage earlier using methods such as mulching, and then the 2100 crop in zone 2 can be harvested after reaching the mature seedling stage, achieving intercropping between vigorous growth and seedling stages. The final crop in winter (or late autumn) can be harvested sequentially or simultaneously. Overall, the above methods can achieve intercropping between vigorous growth and seedling stages. Harvesting is the most direct method of growth inhibition, and the absence of overwintering methods (i.e., harvesting all crops before winter) gives this invention a greater advantage in fully utilizing sunlight.

[0075] The fertilization includes one or more of liquid fertilizer and solid fertilizer; the liquid fertilizer includes one or more of inorganic liquid fertilizer, organic liquid fertilizer, and liquid bud-promoting agents; the solid fertilizer includes one or more of inorganic solid fertilizer, organic solid fertilizer, and solid bud-promoting agents. Both the organic liquid fertilizer and the organic fixed fertilizer contain humic acid and / or humate salts.

[0076] For fast-growing crops that can be harvested multiple times a year, with an annual harvest yield of up to tens of tons per acre, sufficient inorganic and organic fertilizers are crucial for their healthy growth. Using liquid or solid bud-promoting agents can encourage stem / root germination after harvest, mitigating the impact of low sunlight utilization during the post-harvest / young shoot stage and increasing crop productivity. The type of fertilization—solid, liquid, inorganic, organic, or a combination of both—is not specifically limited; it should be adapted to local conditions and circumstances. Both the organic liquid fertilizer and the organic solid fertilizer contain humic acid and / or humate salts. Humic acid and / or humate salts have both fast-acting and long-lasting properties, which means they can improve the soil and promote the absorption of inorganic fertilizers (nitrogen, phosphorus, potassium, etc.), while being difficult to digest themselves (the main effective components of the black soil in Northeast China). They also help to build soil aggregates. Therefore, whether it is solid organic fertilizer or liquid organic fertilizer, soil-improving fertilizer or supplemental fertilizer, it is recommended to contain humic acid and / or humate salts for the high-yield planting method of this invention.

[0077] like Figures 2a-2b and Figures 3a-3c As shown, the wheel or track travel path 2200 is used for harvesting. The wheels or tracks of the device and transport unit provide the necessary path for movement, without needing to include the entire vehicle body. Unlike traditional planting methods, when harvesting crops that have entered the harvesting stage, there are crops about to enter the vigorous growth stage (large seedling stage) in the adjacent land. For example, if the crops in the harvesting stage are 2 meters tall, the adjacent crops entering the large seedling stage will be 1 meter tall. Furthermore, as mentioned earlier, the stalks of the planted crops are easily damaged by pressure and may puncture the tires of the harvesting or transport unit. Therefore, a wheel or track path 2200 needs to be set up during the planting process to provide a path for the wheels or tracks of the harvesting and transport units.

[0078] Crops in the first or second zone are harvested using harvesting and transport devices. Each of the first and second zones includes at least one planting unit, and the harvesting is carried out in one or more of the following manner: The harvesting device and the transport device are the same equipment; The harvesting device and the transport device travel in a front-to-back sequence within the same planting unit, with the harvesting device harvesting first and the transport device receiving second. The harvesting device and the transport device operate independently in different planting units.

[0079] Both the first and second zones include at least one planting unit. In this invention, one planting unit constitutes one zone; that is, the first zone includes one planting unit, and the second zone includes one planting unit. When the harvesting device and the transport device travel across planting units, if they travel between planting units, the area under the transport device can be the already harvested crop, requiring no further consideration. However, if they travel adjacent to a planting unit, the area under the transport device is the crop about to enter its vigorous growth stage (large seedling stage), and the chassis needs to be appropriately raised to avoid damaging the large seedling stage crop. For example, taking the planting of tall, fast-growing crops (each planting unit is 2 meters wide) as an example, the travel mode of the harvesting device and the transport device is as follows: Figures 3b-3c As shown. When not traveling across planting units, as Figure 3b As shown: Harvesting device 4201 can both harvest and transport, meaning it can be the same device. The first zone 2000 on the left has already been harvested, and this area contains post-harvest / sprouting crops, i.e., crops with status indicator 1000 on day 0. The harvesting device is currently harvesting in the middle first zone 2000; the unharvested area contains crops with status indicator 1400 on day 60, and the harvested area contains crops with status indicator 1000 on day 0. The first zone 2000 on the right contains unharvested crops with status indicator 1400 on day 60. The second zone 2100 contains crops with status indicator 1200 on day 30. Harvesting device 4201 enters the first zone 2000 for operation via the wheel or track travel path 2200 between adjacent first and second zones.

[0080] Harvesting device 4202 (No. 2) and transport device 4301 (No. 1) travel in a sequential order within the same planting unit. Harvesting device 4202 harvests first, and transport device 4301 receives second. Therefore, harvesting device 4202 and transport device 4301 are two separate pieces of equipment. Material transfer is achieved through a robotic arm. Specifically, one end of the robotic arm is fixed to harvesting device 4202, and the other end is attached to transport device 4301. Harvesting device 4202 transports the harvested crop to transport device 4301 via the robotic arm.

[0081] When harvesting across planting units, such as Figure 3cAs shown: Harvesting device 4203 (No. 3) and transport device 4302 (No. 2) travel back and forth in adjacent planting units. Harvesting device 4203 travels within the first zone 2000, while transport device 4302 travels within the adjacent second zone 2100. The chassis of transport device 4302 is higher than the height of the crops in the second zone 2100. At this time, the crops in the second zone 2100 with a status indicator of 1200 on day 30, i.e., the chassis of transport device 4302, are higher than the crops with a status indicator of 1200 on day 30. The first zone 2000 on the far left has been harvested, and this is currently the harvested / sprouting stage crop, i.e., the crop with status mark 1000 on day 0. Harvesting device 3 4203 is currently harvesting in the middle first zone 2000. The unharvested area is the crop with status mark 1400 on day 60, and the harvested area is the crop with status mark 1000 on day 0. Transport device 2 4302 is traveling in the adjacent second zone. The first zone 2000 on the right is the unharvested area with status mark 1400 on day 60. The wheel or track travel path 2200 between the adjacent first and second zones allows harvesting device 3 4203 and transport device 2 4302 to enter and operate in the first zone 2000 and the second zone 2100.

[0082] Harvesting device 4204 runs parallel or sequentially with transport devices 4303 and 4304, separated by one planting unit. Harvesting device 4204 travels in Zone 1 (2000), while transport devices 4303 and 4304 travel in the harvested Zone 1 (leftmost Zone 1). There are no special requirements for chassis height. They are separated by one Zone 2 (planting unit). Zone 1 (2000) on the left has been harvested, and this is the post-harvest / sprouting stage crop, i.e., the crop with status indicator 1000 on day 0. The transport devices travel in this area. Harvesting device 4204 is currently harvesting in the middle Zone 1. The unharvested area is the crop with status indicator 1400 on day 60, and the harvested area is the crop with status indicator 1000 on day 0. Zone 1 (2000) on the right is the unharvested area of ​​the crop with status indicator 1400 on day 60. Furthermore, the wheel or track travel path 2200 between the adjacent first and second zones allows harvester 4204, transporter 3 4303, and transporter 4304 to enter the first and second zones for operation.

[0083] The harvesting device is a single-zone harvesting device or an intermittent zone harvesting device. The single-zone harvesting device refers to a harvesting platform that is continuously arranged in the harvesting width direction of the harvesting device; the intermittent zone harvesting device refers to a harvesting platform that is spaced apart in the harvesting width direction of the harvesting device.

[0084] Specifically, such as Figure 3a As shown in Harvesting Method 1, the fast-growing crops in the first zone are in a state of waiting to be harvested. That is, the first zone 2000 on the left is harvesting area 1 (4001), the first zone 2000 in the middle is harvesting area 2 (4002), and the first zone 2000 on the right is harvesting area 3 (4003). The fast-growing crops planted in the first zone 2000 on the left are: fast-growing crop 1406 (numbered 6 on day 60), fast-growing crop 1407 (numbered 7 on day 60), fast-growing crop 1408 (numbered 8 on day 60), fast-growing crop 1409 (numbered 9 on day 60), and fast-growing crop 1410 (numbered 10 on day 60). The fast-growing crops planted in the first zone 2000 in the middle are: fast-growing crop 1411 (numbered 11 on day 60), fast-growing crop 1412 (numbered 12 on day 60), fast-growing crop 1413 (numbered 13 on day 60), fast-growing crop 1414 (numbered 14 on day 60), and fast-growing crop 1415 (numbered 15 on day 60). The fast-growing crops planted in the first zone 2000 on the right are: fast-growing crop 1416 (numbered 16 on day 60), fast-growing crop 1417 (numbered 17 on day 60), fast-growing crop 1418 (numbered 18 on day 60), fast-growing crop 1419 (numbered 19 on day 60), and fast-growing crop 1420 (numbered 20 on day 60).

[0085] The area between Zone 1 (2000) on the left and Zone 1 (2000) in the middle is Zone 2 (2100) on the left. The fast-growing crops planted in Zone 2 (2100) are: Day 30, No. 6 (1206), Day 30, No. 7 (1207), Day 30, No. 8 (1208), Day 30, No. 9 (1209), and Day 30, No. 10 (1210). The area between Zone 1 (2000) in the middle and Zone 1 (2100) on the right is Zone 2 (2100) in the middle. The fast-growing crops planted in Zone 2 (2100) are: Day 30, No. 11 (1211), Day 30, No. 12 (1212), Day 30, No. 13 (1213), Day 30, No. 14 (1214), and Day 30, No. 15 (1215). The area to the right of the first zone on the right is the second zone on the right. The fast-growing crops planted in the second zone on the right are: fast-growing crop 1216 (numbered 16 on day 30), fast-growing crop 1217 (numbered 17 on day 30), fast-growing crop 1218 (numbered 18 on day 30), fast-growing crop 1219 (numbered 19 on day 30), and fast-growing crop 1220 (numbered 20 on day 30). Harvesting is carried out according to harvesting method 1 for fast-growing crops in the first zone 2000. The harvesting device is an interval zone harvesting device, and harvesting platforms 1 (4101), 2 (4102), and 3 (4103) are spaced apart along the harvesting width (e.g., 10 meters wide) of the harvesting device. A wheel or track travel path 2200 is established between adjacent first zone 2000 and second zone 2100.

[0086] As shown in harvesting method 2, the fast-growing crops in Zone 1 2000 are in a state awaiting harvest. Zone 1 2000 is harvesting area 4004 (number 4). Specifically, the fast-growing crops planted in Zone 1 2000 are: fast-growing crop 1421 (number 21 on day 60), fast-growing crop 1422 (number 22 on day 60), fast-growing crop 1423 (number 23 on day 60), fast-growing crop 1424 (number 24 on day 60), and fast-growing crop 1425 (number 25 on day 60). Harvesting is carried out according to harvesting method 2 on the fast-growing crops in Zone 1 2000. The harvesting device is a single-zone harvesting device, and harvesting platform 4104 is continuously arranged in the harvesting width direction of the harvesting device. Furthermore, the wheel or track travel path 2200 is between adjacent Zone 1 2000 and Zone 2100.

[0087] As shown in harvesting method 3, the fast-growing crops in Zone 1 (2000) are in a state awaiting harvest. Zone 1 (2000) includes harvesting areas 5 (4005), 6 (4006), and 7 (4007). Harvesting is carried out on crops planted during their vigorous growth period and seedling stage in Zone 1 (2000). The fast-growing crops planted in Zone 1 (2000) are: fast-growing crop 1421 (numbered 21 on day 60), fast-growing crop 1422 (numbered 22 on day 60), and fast-growing crop 1423 (numbered 23 on day 60). The fast-growing crops planted in Zone 2 (2100) are: fast-growing crop 1206 (numbered 6 on day 30) and fast-growing crop 1207 (numbered 7 on day 30). Harvesting is carried out according to harvesting method 3 for fast-growing crops within the first zone 2000. The harvesting device is an interval-section harvesting device, with harvesting platforms 5 (4105), 6 (4106), and 7 (4107) spaced apart along the harvesting width direction of the harvesting device. Ditches 2300 are constructed between adjacent planting units in the first zone 2000.

[0088] Both harvesting methods 1 and 3 employ interval harvesting devices, but the difference lies in the span of the robotic arm that mounts the harvesting platform. Harvesting method 1 is primarily for planting in wider areas (e.g., 2 meters wide per area) such as the first zone 2000 and the second zone 2100, with a robotic arm span of nearly 10 meters. Harvesting method 3, on the other hand, is primarily for planting in narrower areas (e.g., 0.5 meters wide per area) such as the first zone 2000 and the second zone 2100, mainly used for planting short-stalked crops (e.g., 0.6 meters high), with a robotic arm span similar to that of the harvesting device (e.g., around 2 meters).

[0089] The planting method further includes: setting up a covering above the area of ​​the roots of the fast-growing crop after harvest to prevent the roots of the fast-growing crop after harvest from freezing in winter; the covering includes one or more of the following: one or more layers of agricultural mulch film; one or more layers of bubble wrap; straw or organic fertilizer; arched sheds and soil.

[0090] Most fast-growing crops that can be harvested multiple times a year are tall, tropical crops. If grown outdoors in cold northern regions, their roots and rhizomes are easily killed by frost. To address this issue, one approach is to use crop breeding (such as Golden Forage Grass) to enhance root frost resistance, and another is to install mulch around the crop roots before winter. Specifically, for example... Figure 4 As shown, the fast-growing crops after harvest are specifically: fast-growing crop 1006 (day 0, number 6), fast-growing crop 1007 (day 0, number 7), fast-growing crop 1008 (day 0, number 8), fast-growing crop 1009 (day 0, number 9), fast-growing crop 1010 (day 0, number 10), fast-growing crop 1011 (day 0, number 11), fast-growing crop 1012 (day 0, number 12), fast-growing crop 1013 (day 0, number 13), fast-growing crop 1014 (day 0, number 14), and fast-growing crop 1015 (day 0, number 15). These crops can be covered sequentially with 5000g of straw, 5100g of soil, and 5200g of plastic film, and a greenhouse 5400g can be installed on the outside to further improve the heat preservation effect. Furthermore, the film pressing device 5300 (such as soil, sticks, pressing device, etc.) is set at both ends of the greenhouse body 5400 to press the ground film 5200 and the arched greenhouse 5400, preventing the ground film 5200 and the arched greenhouse 5400 from being blown up, shifted or loosened by the wind, thereby improving the stability of heat preservation.

[0091] Adjustments can be made based on the minimum temperature of different regions and the cold resistance of the roots and stems of the fast-growing crops. For crops that are not cold-resistant, insulation measures are more complex in cold-weather regions; for cold-resistant crops, they are simpler. If using a layer of agricultural mulch, care must be taken to prevent the mulch from being punctured by the often hard stems of the remaining crops, which would affect the insulation effect. Using chopped straw (5000) will generate a certain amount of heat during fermentation, which is beneficial for the early growth of crops in spring.

[0092] The planting method also includes supplementing carbon dioxide, specifically in the first area and / or the second area, and the carbon dioxide is supplemented frequently. The frequency of carbon dioxide supplementation is determined according to the planting environment of the fast-growing crop, the type of fast-growing crop, and its growth status.

[0093] When open planting is adopted in the first and / or second zones, a carbon dioxide leakage reduction device is installed in the first and / or second zones. The carbon dioxide leakage reduction device includes uprights and airtight equipment between the uprights. Specifically, open planting refers to open-field planting in the first and / or second zones. When open-field planting is adopted, carbon dioxide may diffuse when supplementing the first and / or second zones. To reduce carbon dioxide diffusion, a carbon dioxide leakage reduction device can be installed.

[0094] For fast-growing crops that can be harvested multiple times a year, the annual yield can reach tens of tons, requiring a large amount of carbon dioxide. This is especially true in areas far from industrial zones or with high forest coverage, where proper adjustment of carbon dioxide concentration can promote rapid crop growth. Thus, supplementing carbon dioxide (CO2), particularly through regular supplementation, will promote the growth of fast-growing crops that can be harvested multiple times a year.

[0095] For large-scale planting, such as planting on tens or even hundreds of thousands of acres, especially in the south, open-field planting is a good option. However, if carbon dioxide is supplemented, there is a risk that it can easily diffuse into the air, particularly by wind. This invention addresses this by supplementing carbon dioxide under clear skies, with ample sunlight and no wind; and by utilizing the fact that carbon dioxide (CO2) is heavier than air, it incorporates a CO2 leakage reduction device. This further reduces wind speed in the planting area and minimizes excessive diffusion of settled carbon dioxide. The CO2 leakage reduction device includes pillars and an impermeable panel or membrane between the pillars. Figures 5a-5b As shown, the carbon dioxide leakage reduction device includes a column 6000, a fixing structure 6100, an airtight panel or membrane 6200, and ground piles 6300; the column 6000 is compacted and fixed by the ground piles 6300, and the airtight panel or membrane 6200 is installed between adjacent columns 6000 by the fixing structure 6100 to reduce carbon dioxide leakage. Figure 5b As shown, the CO2 leakage reduction device also includes an on / off vent 6400 to improve ventilation in the planting area, facilitating the entry and exit of harvesting equipment and preventing excessive sealing from breeding bacteria. Specifically, the CO2 leakage reduction device surrounds the first zone 2000 and the second zone 2100, and a wheel / track travel path 2200 is provided between the first zone 2000 and the second zone 2100.

[0096] The soil improvement materials used include one or more organic matter with different degradation cycles, and at least one of these organic matter has a degradation cycle of 2 years or more. In other words, the soil improvement materials used include one or more organic matter with different degradation cycles. For the cultivation of fast-growing crops multiple times a year, to reduce the replanting problems caused by deep plowing after planting, the soil is often tilled every few years or even more than ten years. Therefore, the soil needs to have a certain amount of organic matter to meet the needs of many years of cultivation. Different organic matter, such as cellulose and hemicellulose in organic fertilizers, may be consumed within a year, while rice husks require 2-3 years, and humic acid or humates can be maintained for decades. Therefore, for soil improvement of fast-growing crops multiple times a year, using organic fertilizers rich in humic acid or humates, combined with recalcitrant organic matter such as rice husks, and appropriately adding organic fertilizers rich in humic acid or humates during supplemental fertilization, can achieve good results in maintaining good soil aeration / water permeability and high inorganic fertilizer absorption capacity in the long term.

[0097] The planting method described herein is applied to greenhouse cultivation environments. Northern my country, especially the Northwest, has vast plains, which is of great significance for cultivating large areas of fast-growing crops annually as energy crops. However, low temperatures are an unavoidable challenge in northern cultivation. Therefore, greenhouse cultivation, especially cost-effective greenhouse cultivation, is an excellent option. While greenhouse cultivation primarily addresses the temperature issue, it does not solve the problem of improving sunlight utilization. Using the method of this invention, greenhouse cultivation can also improve sunlight utilization, achieving the same effect as the traditional methods and the method of this invention described above, which will not be elaborated further here.
