Description

Technical Field

[0001] This invention relates to the field of crop cultivation technology, specifically to a method for cultivating fast-growing crops that can be harvested multiple times a year. Background Technology

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

[0003] Traditional methods of cultivating fast-growing crops, such as giant reed grass in southern regions, typically involve direct sowing or transplanting in open fields. Specifically, after each harvest, crop residues and rootstocks cannot be removed, leaving the land continuously occupied. At this time, the crop is in its early regeneration stage, with a low leaf area index and minimal light requirements. This results in a significant period between harvests (approximately one-third to one-half of the entire growth cycle) where the land is occupied but solar energy is not efficiently utilized for material conversion, leading to a waste of light and heat resources. To address this issue, some improved solutions have explored greenhouse seedling cultivation technology. This involves concentrated seedling cultivation in greenhouses during the period before the warmer months when sunlight intensity is lower but the land is idle. Because seedlings occupy a small area and have relatively low light requirements, the planting time can be advanced to some extent, allowing for approximately one more month of sunlight utilization each year.

[0004] However, the above-mentioned solutions are limited by the annual characteristics of crops. Their core lies in improving the economic value of crops or extending their growing season by raising seedlings in advance, but they do not fundamentally change the light energy utilization efficiency during the crop's field growth period, and the improvement in overall solar energy utilization is limited. In addition, another solution uses greenhouse cultivation technology, which artificially regulates the planting environment (mainly temperature) to allow agricultural production to continue in winter in cold regions or during cold waves in subtropical regions. While this technology effectively extends the effective land use time in northern and even subtropical regions, it has significant limitations: first, the construction cost of greenhouse facilities is high, making it difficult to promote this technology on a large scale; second, for fast-growing crops that are harvested multiple times a year, even with greenhouse cultivation, the core problems of land idleness and low solar energy utilization after harvest remain unresolved.

[0005] Therefore, the question is how to provide a planting method for fast-growing crops that can be harvested multiple times a year to solve the technical problems of land being idle after harvest and low utilization of sunlight. Summary of the Invention

[0006] This invention provides a method for planting fast-growing crops that can be harvested multiple times a year, in order to solve the technical problems of idle land after harvest and low utilization rate of sunlight.

[0007] This invention provides a method for planting fast-growing crops that can be harvested multiple times a year, comprising: S1: Plant fast-growing crops in the seedling stage in a portable planting device; S2: The transportable planting device, in which the fast-growing crop in the seedling stage is planted, is transported to the first growth area so that the fast-growing crop in the seedling stage can grow in the first growth area; S3: Once the fast-growing crop in the seedling stage has grown into a fast-growing crop in its vigorous growth stage, the transportable planting device containing the fast-growing crop in its vigorous growth stage will be transported to the second growth zone so that the fast-growing crop in its vigorous growth stage can grow in the second growth zone. S4: Once the fast-growing crops in their vigorous growth period have reached maturity, harvest the mature fast-growing crops. S5: Take the harvested fast-growing crops remaining in the transportable planting device as fast-growing crops in the seedling stage, and repeat steps S2-S5. The first spacing between adjacent transportable planting devices in the second growth zone is greater than the second spacing between adjacent transportable planting devices in the first growth zone.

[0008] Optionally, it further includes: a unit cross-planting area, the unit cross-planting area including one first growth area and at least two second growth areas.

[0009] Optionally, the transportable planting device is equipped with wheels and a braking assembly that is connected to the wheels and controls their movement; and / or The portable planting device is equipped with a transport trough, which is used to lift the base plate of the portable planting device to a height greater than or equal to a first set height from the ground.

[0010] Optionally, it further includes: setting up a multi-layer rack in the first growth area, the multi-layer rack having at least two layers for deploying the transportable planting device.

[0011] Optionally, wind protection devices are installed in the first growth zone and / or the second growth zone.

[0012] Optionally, the windbreak device includes a fixing device and a connecting device, wherein the fixing device is fixed in the first growth area and / or the second growth area, and the connecting device is installed between adjacent fixing devices.

[0013] Optionally, it also includes: When the first growth zone is in low light or no light, provide supplemental lighting to the fast-growing crops in the first growth stage; and / or When the second growth zone is in low light or no light, provide supplemental lighting to the fast-growing crops in the second growth state.

[0014] Optionally, it further includes supplementing the first growth zone and / or the second growth zone with carbon dioxide.

[0015] Optionally, when the first growth zone and / or the second growth zone adopts open planting, a carbon dioxide leakage prevention device is installed in the first growth zone and / or the second growth zone; The carbon dioxide leak prevention device includes a second ground stake, a leak prevention plate and / or membrane, wherein the leak prevention plate and / or membrane are installed between adjacent ground stakes.

[0016] Optionally, the planting method is applied in a greenhouse planting environment.

[0017] Compared with the prior art, the present invention has the following advantages: This invention provides a method for planting fast-growing crops that can be harvested multiple times a year, comprising: S1: planting fast-growing crops in the seedling stage in a portable planting device; S2: transporting the portable planting device containing the fast-growing crops in the seedling stage to a first growth zone, so that the fast-growing crops in the seedling stage can grow in the first growth zone; S3: after the fast-growing crops in the seedling stage have grown to the vigorous growth stage, transporting the portable planting device containing the fast-growing crops in the vigorous growth stage to a second growth zone, so that the fast-growing crops in the vigorous growth stage can grow in the second growth zone; S4: after the fast-growing crops in the vigorous growth stage have grown to maturity, harvesting the mature fast-growing crops; S5: using the harvested fast-growing crops remaining in the portable planting device as the fast-growing crops in the seedling stage, and repeating steps S2-S5; wherein, the first distance between adjacent portable planting devices in the second growth zone is greater than the second distance between adjacent portable planting devices in the first growth zone.

[0018] This invention provides a method for planting fast-growing crops that can be harvested multiple times a year. The method includes a first growth zone and a second growth zone. The first growth zone is used for planting seedlings, and the second growth zone is used for planting crops in their vigorous growth stage. Transportable planting devices are deployed in the first growth zone at a second spacing, and in the second growth zone at a first spacing, where the first spacing is greater than the second spacing. In other words, this invention separates the seedling stage crops from the vigorous growth stage crops. The fast-growing seedlings are planted in transportable planting devices and then transported to the first and second growth zones for further growth. Because the branches (stems) and leaves of the seedlings are not fully developed, or they are in the germination or seedling stage, their growth is slow and their sunlight utilization rate is low, allowing for clustered planting. Meanwhile, the vigorous growth stage crops have strong photosynthetic capacity and are planted sparsely, with the first spacing greater than the second spacing. Therefore, this method improves the utilization rate of land and sunlight, and also increases the number of harvests for fast-growing crops, thereby enhancing their economic value.

Detailed Implementation

[0034] Numerous specific details are set forth in the following description to provide a full understanding of the invention. However, the invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0035] In the description of this invention, it should be understood that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0036] 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.

[0037] Next, the planting method for a fast-growing crop that can be harvested multiple times a year, provided by the present invention, will be described in detail with reference to the accompanying drawings.

[0038] like Figure 1a , Figures 2a to 2d As shown, this invention provides a method for planting fast-growing crops that can be harvested multiple times a year. Fast-growing crops (hereinafter referred to as fast-growing crops) refer to crops that can be harvested multiple times a year, and different fast-growing crops may have different growth cycles. Giant Napier grass, which can be harvested every 60 days, is used as an example, but the method is not limited to giant Napier grass; fast-growing crops can also be wheat straw, alfalfa, etc. Therefore, the specific type of fast-growing crop is not limited here. Figure 2c As shown, for ease of understanding of the present invention, its growth cycle is simply divided into stages: fast-growing crops after harvest / in the seedling stage are seedling fast-growing crops, for example, fast-growing crops with a status mark of 1000 on day 0, specifically fast-growing crops 1016 (marked 16 on day 0), fast-growing crops 1017 (marked 17 on day 0), and fast-growing crops 1018 (marked 18 on day 0) within the transportable planting device 3000. And fast-growing crops with a status mark of 1100 on day 15, specifically fast-growing crops 1101 (marked 1 on day 15), fast-growing crops 1102 (marked 2 on day 15), and fast-growing crops 1103 (marked 3 on day 15) within the transportable planting device 3000.

[0039] Fast-growing crops that have reached their peak growth period, such as fast-growing crops marked with status 1200 on day 30, specifically fast-growing crops 1207 marked with status 7 on day 30, fast-growing crops 1208 marked with status 8 on day 30, and fast-growing crops 1209 marked with status 9 on day 30, within the transportable planting device 3000; and fast-growing crops marked with status 1300 on day 45, specifically fast-growing crops 1301 marked with status 1 on day 45, fast-growing crops 1302 marked with status 2 on day 45, and fast-growing crops 1303 marked with status 3 on day 45, within the transportable planting device 3000. When crops reach maturity and are ready for harvest, for example, fast-growing crops marked as 1400 on day 60, specifically, fast-growing crops 1410 (marked as 10 on day 60), 1411 (marked as 11 on day 60), and 1412 (marked as 12 on day 60) within the transportable planting device 3000, mature fast-growing crops are harvested and then return to the seedling stage to begin the next cycle. Figure 1aThe image shows the harvested crop. The above description, exemplarily based on the number of days for the seedling, vigorous growth, and maturity stages of fast-growing crops, illustrates the switching logic between different growth states. In practice, this can be adjusted according to the crop variety, climate conditions, and cultivation conditions. Of course, the seedling, vigorous growth, and maturity stages can also be divided based on the specific plant height and number of true leaves of the fast-growing crop, which will not be listed here.

[0040] like Figure 1b As shown, S1: Fast-growing crops in the seedling stage are planted in a transportable planting device; planting fast-growing crops in a transportable planting device is mainly for convenient subsequent transportation. Specialized mechanical equipment, such as a transplanter or planting machine, can be used to plant fast-growing crops in the seedling stage within the transportable planting device 3000. Furthermore, fast-growing crops in the seedling stage refer to both seedlings and / or harvested crops, specifically including fast-growing crops from day 0 to day 29 (including the end value; the time range in this invention includes the end value). The characteristic of fast-growing crops at this stage is that their leaves are not lush.

[0041] Portable planting devices are designed for growing fast-growing crops. Therefore, they need to meet, but are not limited by, the basic conditions required by these crops. For example, the device should be filled with a suitable substrate, ensuring it is breathable, retains water and nutrients effectively, and is free of pathogens. Furthermore, depending on the needs of the fast-growing crop, the substrate can be formulated with slow-release fertilizers or sterile inorganic planting substrates and nutrient solutions. The formulation of slow-release fertilizers and nutrient solutions can be tailored to the specific growth requirements and environmental conditions of the fast-growing crop; therefore, there are no excessive restrictions. Additionally, the portable planting device must also meet the basic requirements of fast-growing crops, such as water and humidity.

[0042] Furthermore, the materials and structure of the portable planting device can be customized according to the growth characteristics and specific needs of the fast-growing crop, and the internal space of the portable planting device must be matched to the growth requirements of the fast-growing crop. At the same time, the portable planting device is not easily damaged during watering and transportation, ensuring its service life.

[0043] S2: The transportable planting device, in which the fast-growing crop in the seedling stage is planted, is moved to the first growth area so that the fast-growing crop in the seedling stage can grow in the first growth area. Specifically, the transportable planting device, in which seedlings and / or harvested crops are planted, is moved to the first growth area for growth.

[0044] S3: Once the fast-growing crop in the seedling stage has grown to its vigorous growth stage, the transportable planting device containing the fast-growing crop in its vigorous growth stage is moved to the second growth zone so that the fast-growing crop in its vigorous growth stage can grow in the second growth zone. Specifically, the transportable planting device can be moved using transportation equipment or handling equipment.

[0045] S4: Once the fast-growing crops in their vigorous growth period have reached maturity, harvest the mature fast-growing crops. S5: Take the harvested fast-growing crops remaining in the transportable planting device as fast-growing crops in the seedling stage, and repeat steps S2-S5.

[0046] The harvested crop refers to the fast-growing crop remaining in the transportable planting device after harvesting. This fast-growing crop can be used as the seedling stage crop for the next crop. For example... Figure 1a As shown, specifically, the fast-growing crops 1401 (labeled 1 on day 60), 1402 (labeled 2 on day 60), 1403 (labeled 3 on day 60), 1404 (labeled 4 on day 60), 1405 (labeled 5 on day 60), 1406 (labeled 6 on day 60), 1407 (labeled 7 on day 60), 1408 (labeled 8 on day 60), and 1409 (labeled 9 on day 60) within the transportable planting device 3000 are harvested. The harvesting of the mature fast-growing crops can be carried out by a harvester. After harvesting, the fast-growing crops are in the seedling stage (day 0, marked as 1000), which is the remaining harvested crops in the transportable planting device. Specifically, these are fast-growing crops 1001 (day 0, marked as 1), 1002 (day 0, marked as 2), 1003 (day 0, marked as 3), 1004 (day 0, marked as 4), 1005 (day 0, marked as 5), 1006 (day 0, marked as 6), 1007 (day 0, marked as 7), 1008 (day 0, marked as 8), and 1009 (day 0, marked as 9). The transportable planting device containing these seedling fast-growing crops is then moved to the first growth area for further growth, and the previous steps are repeated continuously. The end of the cycle can be determined based on the specific growth environment of the fast-growing crops and is not limited here.

[0047] After harvesting mature, fast-growing crops, they are not discarded or replanted; instead, the rootstock is used directly for the next seedling stage of regeneration. For example... Figure 2cTaking giant reed grass, which is harvested every 60 days, as an example, the transportable planting device 3000 plants giant reed grass in the state marked as 1000 on day 0, specifically fast-growing crop 1016 (marked as day 0, number 16), fast-growing crop 1017 (marked as day 0, number 17), and fast-growing crop 1017 (marked as day 0, number 18) within the transportable planting device 3000; and fast-growing crop 1100 in the state marked as day 15, specifically fast-growing crop 1101 (marked as day 15, number ...

[0048] Fast-growing crops that have reached their peak growth stage, for example, fast-growing crops marked with a status of 1200 on day 30, specifically fast-growing crops 1207 (marked 7 on day 30), 1208 (marked 8 on day 30), and 1209 (marked 9 on day 30) within the transportable planting device 3000; and fast-growing crops marked with a status of 1300 on day 45, specifically fast-growing crops 1301 (marked 1 on day 45), 1302 (marked 2 on day 45), and 1303 (marked 3 on day 45) within the transportable planting device 3000. Fast-growing crops marked with a status of 1400 on day 60, specifically fast-growing crops 1410 (marked 10 on day 60), 1411 (marked 11 on day 60), and 1412 (marked 12 on day 60) within the transportable planting device 3000. During this vigorous growth period, the branches and leaves of fast-growing crops are relatively lush, resulting in severe shading of sunlight between them. Therefore, the initial spacing between adjacent portable planting devices needs to be more generous to increase the utilization rate of sunlight and prevent the fast-growing crops from growing slowly, becoming stunted, and failing to reach harvestable condition for a long time.

[0049] The first distance between adjacent portable planting devices 3000 in the second growth zone 2100 is greater than the second distance between adjacent portable planting devices 3000 in the first growth zone 2000.

[0050] like Figure 2dAs shown in the first growth zone 2000 of the first crop, the fast-growing crop with a status mark of 1000 on day 0 is planted in the portable planting device 3000 in the first growth zone 2000. The corresponding planting units of the portable planting device in the first growth zone 2000 are: first planting unit 2001, first planting unit 2002, first planting unit 2003, first planting unit 2004, first planting unit 2005, first planting unit 2006, first planting unit 2007, and first planting unit 2008. That is, one portable planting device 3000 is deployed in each planting unit in the first growth zone 2000. As mentioned earlier, the first growth zone 2000 is used for planting fast-growing crops in the seedling stage, i.e., planting seedlings and / or post-harvest crops of fast-growing crops. During this stage (0-29 days), the branches of fast-growing crops are relatively short, with minimal mutual shading, allowing for the centralized deployment of transportable planting devices. Figure 2b As shown, since the fast-growing crops 1010 (day 0, number 10), 1011 (day 0, number 11), 1012 (day 0, number 12), 1013 (day 0, number 13), 1014 (day 0, number 14), and 1015 (day 0, number 15) are planted in the portable planting device 3000, the adjacent portable planting devices 3000 are placed relatively close together, which can reduce the spacing between adjacent portable planting devices 3000 and the loss of sunlight coverage utilization.

[0051] like Figure 2c Once the fast-growing crops in the seedling stage have reached their vigorous growth stage, the transportable planting device containing these vigorous growth crops will be moved to the second growth zone. The second growth zone is used to grow vigorous growth crops with abundant branches and leaves and strong photosynthesis. The initial spacing between the transportable planting devices can be increased to allow them to receive more solar radiation and ensure that the second growth zone can continuously support the vigorous growth crops. Figure 2aAs shown, the fast-growing crops planted in the transportable planting device are fast-growing crops 1201 (labeled 1 on day 30), fast-growing crops 1202 (labeled 2 on day 30), fast-growing crops 1203 (labeled 3 on day 30), fast-growing crops 1204 (labeled 4 on day 30), fast-growing crops 1205 (labeled 5 on day 30), and fast-growing crops 1206 (labeled 6 on day 30). At this time, the fast-growing crops are in their vigorous growth period, and the leaves 1 (e.g., 4001) and leaves 2 (e.g., 4002) of the vigorous fast-growing crops in the adjacent transportable planting devices 3000 can fully cover the gaps between the adjacent transportable planting devices 3000. There are only very small gaps 4101 between leaves 1 and leaves 2 that allow light to pass through to the ground, and very little sunlight 4201 falls to the ground, in order to improve the sunlight coverage utilization rate of the fast-growing crops. Thus, if the second spacing of the first growth zone is still used to deploy the transportable planting devices, it will result in the fast-growing crops being too dense, which will affect their growth. Conversely, if during the seedling stage, especially after planting and / or after harvesting, crops are treated with... Figure 2a The first spacing shown indicates that the portable planting devices are positioned so that the gaps between them receive ample sunlight most of the time. For example, based on the first spacing and the size of the portable planting devices (3000), this results in wasted sunlight coverage. However, using an alternating method ensures sufficient sunlight for crop growth during its vigorous growth period while significantly reducing sunlight waste after harvest and during the seedling stage.

[0052] In terms of specific implementation, such as Figure 2d As shown in the first crop of the second growth zone 2100, the portable planting device in the second growth zone 2100 is planted with fast-growing crops whose status is marked as 1200 on day 30. The corresponding planting units of the portable planting device in the second growth zone 2100 are: Planting Unit 1 2101, Planting Unit 3 2103, Planting Unit 5 2105, Planting Unit 7 2107, Planting Unit 10 2110, Planting Unit 12 2112, Planting Unit 14 2114, and Planting Unit 16 2116 of the second growth zone. That is, one portable planting device is deployed every other planting unit in the second growth zone. As mentioned earlier, the second growth zone is used to plant fast-growing crops in their vigorous growth period. During this stage (30-59 days), the fast-growing crops are lush and leafy, and the mutual shading of sunlight has a strong impact. The portable planting devices can be deployed sparsely. Figure 2a As shown, the adjacent portable planting devices 3000 are placed at relatively large intervals (such as one portable planting device deployed every other planting unit in this embodiment), which is conducive to the vigorous growth of fast-growing crops.

[0053] After fast-growing crops reach maturity, such as Figure 2dAs shown after the first crop matures, the corresponding planting units in the second growth zone 2100 are: Planting Unit 1 2101, Planting Unit 3 2103, Planting Unit 5 2105, Planting Unit 7 2107, Planting Unit 10 2110, Planting Unit 12 2112, Planting Unit 14 2114, and Planting Unit 16 2116 in the second growth zone. The fast-growing crops within the transportable planting devices in these units grow from their vigorous growth stage (day 30, status indicator 1200) to their mature stage (day 60, status indicator 1400). The specific status of the mature fast-growing crops is as follows: Figure 2c The state on day 60 is as follows: fast-growing crop 1410 (number 10), fast-growing crop 1411 (number 11), and fast-growing crop 1412 (number 12). The mature fast-growing crops are harvested. The state after the first harvest is as follows: Figure 2d As shown after the first harvest, the planting units corresponding to the second growth zone 2100 are: Planting Unit 1 2101, Planting Unit 3 2103, Planting Unit 5 2105, Planting Unit 7 2107, Planting Unit 10 2110, Planting Unit 12 2112, Planting Unit 14 2114, and Planting Unit 16 2116 in the second growth zone. The fast-growing crops within these units, marked as mature (1400), transition from the harvested state to the post-harvest state. Figure 2c Fast-growing crops with a status of 1000 on day 0.

[0054] Repeat the above steps of switching between planting in the first growth zone and planting in the second growth zone. For example, the specific switching method is as follows: Figure 2d After the first harvest, switch to the second harvest method. After the first harvest, as mentioned before, such as... Figure 2d As shown in the post-harvest state, the fast-growing crops in the corresponding planting units of the original second growth zone 2100—planting unit 1 2101, planting unit 3 2103, planting unit 5 2105, planting unit 7 2107, planting unit 10 2110, planting unit 12 2112, planting unit 14 2114, and planting unit 16 2116—within the transportable planting device 3000 have transitioned from the maturity stage (day 60) status marker 1400 to the post-harvest crop state as shown below. Figure 2cThis refers to the fast-growing crops whose status is marked as 1000 on day 0. The fast-growing crops within the transportable planting devices 3000 corresponding to the original first growth zone 2000—planting units 2001, 2002, 3003, 4004, 5005, 6006, 7007, and 8008—are grown from seedlings and / or after harvest. Figure 2c The fast-growing crop with a status indicator of 1000 on day 0 of the first crop, when it reaches its vigorous growth stage... Figure 2c Fast-growing crops with a status of 1200 on day 30.

[0055] Neither of the two fast-growing crops is suitable for growth in the corresponding first and second growth zones, requiring transfer and switching. Specifically, fast-growing crops that have reached the vigorous growth stage (state marker 1200) within the transportable planting device 3000 in the first growth zone 2000 are transferred and placed in the corresponding planting units in the second growth zone 2100: Planting Unit 2102, Planting Unit 4, Planting Unit 2104, Planting Unit 6, Planting Unit 2106, Planting Unit 8, Planting Unit 2108, Planting Unit 9, Planting Unit 2109, Planting Unit 11, Planting Unit 2111, Planting Unit 13, Planting Unit 2113, and Planting Unit 15. As mentioned earlier, the first growth zone is used for seedlings and / or post-harvest crops. The harvested crops in the transportable planting devices 3000 within the second growth zone 2100 are fast-growing seedlings with a status indicator of 1000. These are then transported to the corresponding planting units in the first growth zone 2000: Planting Unit 1 2001, Planting Unit 2002, Planting Unit 3 2003, Planting Unit 4 2004, Planting Unit 5 2005, Planting Unit 6 2006, Planting Unit 7 2007, and Planting Unit 8 2008 of the first growth zone. The specific placement of the transportable planting devices in the first and second growth zones is as follows: Figure 2d The second crop is shown as a transition from the first growing zone to the second growing zone after the second growing zone crop has been harvested, where crops that have reached their vigorous growth stage are planted.

[0056] The planting units in the first and second growth zones mentioned above refer to land divided into equal areas according to demand. That is, the planting units in the first and second growth zones have the same area. Planting units can be divided according to the number of acres (mu), such as one acre or two acres per unit. Of course, other values ​​can also be used to set the area of ​​the planting units, subject to restrictions here. Planting units can also be divided according to square meters (square meters), such as 1,000 square meters or 1,200 square meters per unit. These are not listed here; the specific settings can be determined according to specific needs.

[0057] The first and second growth zones are composed of several planting units. Specifically, each growth zone can consist of either eight or ten planting units. The number of planting units in a first or second growth zone can be determined based on specific needs and is not limited here. In actual planting, the total area can reach several thousand, tens of thousands, or even hundreds of thousands of acres.

[0058] In this embodiment, the first spacing between adjacent portable planting devices in the second growth zone is twice or more than the second spacing between adjacent portable planting devices in the first growth zone, thereby improving the utilization rate of sunlight and the annual number of harvests for fast-growing crops. In the specific embodiment described above, the first spacing is several times the second spacing, and the average planting density of the first growth zone is twice the average planting density of the second growth zone. This means that within the same area of ​​the first and second growth zones, the number of portable planting devices deployed in the first growth zone is twice the number deployed in the second growth zone. Thus, by deploying adjacent portable planting devices at the first spacing for crops in their vigorous growth stage, fast-growing crops can receive sufficient sunlight for growth. Conversely, by deploying adjacent portable planting devices at the second spacing for seedling crops, the wasted sunlight coverage due to planting gaps between fast-growing crops can be reduced, thereby improving the utilization rate of sunlight and the annual number of harvests for fast-growing crops.

[0059] like Figure 3a and Figure 3b As shown, the portable planting device is equipped with a walking wheel 3110 and a braking assembly 3120 that is connected to the walking wheel 3110 and controls the walking state of the walking wheel 3110; and / or, the portable planting device is provided with a transport trough 3210, which is used to lift the bottom plate of the portable planting device to a height greater than or equal to a first set height from the ground.

[0060] like Figure 3a and Figure 3bAs shown, the transportable planting device is equipped with wheels 3110 and / or has a transport groove 3210. Furthermore, the transportable planting device is also provided with a braking assembly 3120 that is connected to and controls the wheels. As previously described, in order to realize the transport / switching between planting in the first growth zone and planting in the second growth zone, the present invention requires planting fast-growing crops in the seedling stage within the transportable planting device. To achieve transport, the transportable planting device 3000 is equipped with wheels 3110 and / or has a transport groove 3210. To prevent unnecessary movement caused by wind, the transportable planting device 3100 equipped with wheels includes wheels 3110 and a braking assembly 3120. The braking assembly 3120 can be installed on one set of wheels 3110 or multiple sets of wheels 3110.

[0061] The transportable planting device 3200 equipped with a transport trough includes a transport trough 3210, facilitating transport operations. Specifically, the transport trough is located below the transportable planting device and includes an opening on one side, a connector for inserting the forks of a transport tool, and a base plate at the bottom of the transport trough; the base plate is used to support the soil and fast-growing crops growing within the transportable planting device. In this invention, the initial set height is 5cm-15cm, but this initial set height can be determined according to specific working conditions. The transportable planting device equipped with the transport trough does not roll because of its high friction with the ground, making it difficult to move under windy conditions. This invention exemplarily shows two transport troughs 3210. Since the soil and fast-growing crops it carries may weigh hundreds of kilograms or even more, in specific implementations, three, four, or more can be used, ideally without affecting fork insertion, while maintaining reasonable cost and reliability.

[0062] The planting method described above also includes: setting up a unit cross-planting area, wherein the unit cross-planting area includes one first growth area and at least two second growth areas. Specifically, as follows... Figure 2dAs shown, each unit of the inter-planting area includes a first growth area, and the planting units within the first growth area 2000 are: first growth area first planting unit 2001, first growth area second planting unit 2002, first growth area third planting unit 2003, first growth area fourth planting unit 2004, first growth area fifth planting unit 2005, first growth area sixth planting unit 2006, first growth area seventh planting unit 2007 and first growth area eighth planting unit 2008. The second growth zone comprises at least two second growth zones. Specifically, the planting units corresponding to the first second growth zone are: second growth zone 1 planting unit 2101, second growth zone 2102, second growth zone 3 planting unit 2103, second growth zone 4 planting unit 2104, second growth zone 5 planting unit 2105, second growth zone 6 planting unit 2106, second growth zone 7 planting unit 2107, and second growth zone 8 planting unit 2108; the planting units corresponding to the second second growth zone are: second growth zone 9 planting unit 2109, second growth zone 10 planting unit 2110, second growth zone 11 planting unit 2111, second growth zone 12 planting unit 2112, second growth zone 13 planting unit 2113, second growth zone 14 planting unit 2114, second growth zone 15 planting unit 2115, and second growth zone 16 planting unit 2116. The number of second growth zones and the method of dividing them into units can be adjusted according to the plot area, crop growth cycle and operational capacity, and are not limited to the diagram shown.

[0063] This invention improves the utilization rate of sunlight and increases the number of harvestable crops per year by cross-planting "first growth zone + second growth zone".

[0064] by Figure 2d For example, in this implementation, using a cross-planting method with a 1:2 ratio of the first growth zone to the second growth zone, and taking giant reed grass harvested every 60 days as an example, a simple calculation is performed exemplarily. Assuming the traditional model... Figure 2dThe first second growth zone includes planting units 2101, 2102, 2103, 2104, 2105, 2106, 2107, and 2108 of the second growth zone, and planting units 2109, 2110, 2111, 2112, 2113, 2114, 2115, and 2116 of the second growth zone. The two second growth zones together cover a total area of ​​1 acre. Giant reed grass is planted in the first planting unit 2101, the third planting unit 2103, the fifth planting unit 2105, the seventh planting unit 2107, the tenth planting unit 2110, the twelfth planting unit 2112, the fourteenth planting unit 2114, and the sixteenth planting unit 2116 of the second growth zone.

[0065] When using traditional methods, fast-growing crops are planted directly in the ground and cannot be transported. The growth cycle is 2 months. Therefore, within the second growth zone, planting units 1 (2101), 3 (2103), 5 (2105), 7 (2107), 10 (2110), 12 (2112), 14 (2114), and 16 (2116), six crops can be harvested per year.

[0066] Calculations show that the average number of harvests per acre per year using this traditional planting method is: in: This indicates the average number of harvests per acre per year using traditional planting methods. A represents the total number of acres used for planting; N represents the total number of crops produced in plot B within a year, which is 6 in this case; B represents the area available for harvesting and planting.

[0067] The planting method of this invention, assuming a first growth zone of 2000 m², is used... Figure 2dThe first growing area includes planting units 1-2001, 2-2002, 3-2003, 4-2004, 5-2005, 6-2006, 7-2007, and 8-2008, and two second growing areas as follows: Figure 2d The first plot of 2100 includes: Planting Unit 1 of the Second Growth Zone 2101, Planting Unit 2 of the Second Growth Zone 2102, Planting Unit 3 of the Second Growth Zone 2103, Planting Unit 4 of the Second Growth Zone 2104, Planting Unit 5 of the Second Growth Zone 2105, Planting Unit 6 of the Second Growth Zone 2106, Planting Unit 7 of the Second Growth Zone 2107, and Planting Unit 8 of the Second Growth Zone 2108; and the second plot of 2100 includes: Planting Unit 9 of the Second Growth Zone 2109, Planting Unit 10 of the Second Growth Zone 2110, Planting Unit 11 of the Second Growth Zone 2111, Planting Unit 12 of the Second Growth Zone 2112, Planting Unit 13 of the Second Growth Zone 2113, Planting Unit 14 of the Second Growth Zone 2114, Planting Unit 15 of the Second Growth Zone 2115, and Planting Unit 16 of the Second Growth Zone 2116, totaling 1.5 mu (approximately 0.067 hectares).

[0068] Fast-growing crops, such as giant reed grass, are planted in portable planting devices, with a 30-day difference between the fast-growing crops in the first and second growth zones. The portable planting devices, containing fast-growing crop seedlings and / or harvested crops, are then moved to the first growth zone. Once the fast-growing crops in the first growth zone reach their vigorous growth stage, the portable planting devices are moved to the second growth zone. After the fast-growing crops in the second growth zone have reached their vigorous growth stage, the mature crops are harvested; this process of switching between the first and second growth zone planting steps is repeated. Figure 2d As shown. During continuous cultivation (taking the tropics as an example), the crop growth cycle in the second growth zone is 30 days, and 12 harvests can be made per year.

[0069] Calculations show that the average number of harvests per acre per year under this planting method is: in: This indicates the average number of harvests per acre per year using the cross-planting model of this invention. A represents the total number of acres used for planting, which includes 0.5 acres in the first production area and 1 acre in the second production area; N represents the total number of crops produced by plot B within a year, which is 12 in this case. B represents the area available for harvesting and planting; here it refers to 1 acre in the second production area.

[0070] Therefore, the overall efficiency improvement rate is: As described above, a multi-layered frame is set up in the first growth zone, with at least two layers, for deploying the transportable planting device. Because the seedlings and / or harvested crops planted in the first growth zone, before reaching their vigorous growth stage, at least for a period such as the initial post-harvest period, the proportion of the area occupied by the branches and leaves of the fast-growing crops in the space between crop plants is very small. Figure 2c For fast-growing crops with a status marker of 1000 on day 0, multi-layer planting can be implemented in the first growth zone using multi-layer racks to improve sunlight utilization. Specifically... Figure 5a and Figure 5b As shown, the multi-layer rack 6000 set in the first growth area can be one or more, and each multi-layer rack 6000 can hold no less than two layers of transportable planting devices planted with fast-growing crops, such as the first layer 6001, the second layer 6002, and the third layer 6003 of the multi-layer rack. A second support device 6005 is set between each adjacent layer, that is, each adjacent layer is fixed and supported by the second support device 6005, and each layer can hold a transportable planting device.

[0071] The planting method of the present invention is implemented in the first growth zone using a multi-layer rack system, specifically, as follows: Figure 2e As shown. Assume this method uses two first growth regions of 2000, such as... Figure 2e Zone 2000A (0.25 mu): Planting Unit 1 of the first growth zone, Planting Unit 2 of the first growth zone, Planting Unit 2002 of the first growth zone, Planting Unit 3 of the first growth zone, Planting Unit 4 of the first growth zone, Planting Unit 2004; and Zone 2000B (0.125 mu), using a multi-layer trellis structure (two layers): Planting Unit 5 of the first growth zone, Planting Unit 2005 of the first growth zone, Planting Unit 6 of the first growth zone, Planting Unit 2006; and two plots of the second growth zone, such as... Figure 2eZone 2100A (0.5 mu): Planting units 1-2101, 2102, 3-2103, 4-2104, 5-2105, 6-2106, 7-2107, and 8-2108 of the second growth zone; Zone 2100B (0.5 mu): Planting units 9-2109, 10-2110, 11-2111, 12-2112, 13-2113, 14-2114, 15-2115, and 16-2116 of the second growth zone. Total: 1.375 mu.

[0072] Specifically, this method allows for the continuous support of crops in the second growth zone, 2100A and 2100B, from their vigorous growth period (1200) to maturity (1400), with a 15-day interval between their growth cycles. That is, when the fast-growing crops in zone 2100A are at status marker 1200, the fast-growing crops in zone 2100B are at status marker 1300. Since the harvesting cycle for either zone 2100A or 2100B alone remains 30 days, considering continuous multi-year growth, the second growth zone can yield 12 harvests per year.

[0073] To ensure crop supply to the second growth zone 2100, the first growth zone 2000 continuously ensures that fast-growing crops grow from the state marked as 1100 on day 15 to the state marked as 1200 on day 30. The second growth zone 2000B continuously ensures that fast-growing crops grow from the state marked as 1000 on day 0 to the state marked as 1100 on day 15. The fifth planting unit 2005 and the sixth planting unit 2006 of the first growth zone adopt a multi-layer rack structure (two layers, with one portable planting device on each layer, totaling two), which can save 0.125 acres of land.

[0074] Calculations show that the average number of harvests per acre per year using this planting method is: in: This indicates the average number of harvests per acre per year using the cross-planting method of the present invention and the multi-layered trellis planting method in the first growth zone; A represents the total number of acres planted, which includes 0.375 acres in the first production area and 1 acre in the second production area, totaling 1.375 acres. N represents the total number of crops produced by plot B within a year, where N is 12. B represents the area available for harvesting and planting; here it refers to 1 acre in the second production area.

[0075] Therefore, the overall efficiency improvement rate is: Because the fast-growing crops involved in this invention are often grown outdoors to save costs and increase sunlight utilization, and many fast-growing crops are tall-stalked, they are susceptible to wind damage and lodging. To overcome this risk, windbreak devices are installed in the first and / or second growth areas. The windbreak devices include fixing devices and connecting devices. The fixing devices are fixed in the soil of the first and / or second growth areas, and the connecting devices are installed between adjacent fixing devices. Specifically, as follows... Figure 4 As shown. The windbreak device 5000 includes a fixing device 5300 and a connecting device 5200. The fixing device 5300 includes a first ground stake 5400, a first support device 5500, and a connecting structure 5100 connected to the connecting device 5200. The first ground stake 5400 is fixed in the soil of the first growth area and / or the second growth area, specifically, the first ground stake 5400 is buried below the surface of the first growth area and / or the second growth area. The connecting device 5200 is installed on the first support device 5500 through the connecting structure 5100 to prevent the planted crops from lodging and / or moving unnecessarily due to wind disasters. The connecting device 5200 can be in the form of ropes, straps, cables, or netting, etc.; the fixing device 5300 can also be a re-pluggable structure or a permanent structure.

[0076] In order to increase the number of crop harvests, when the first growth zone is in low light or no light, the fast-growing crops in the first growth stage are given supplemental lighting; and / or when the second growth zone is in low light or no light, the fast-growing crops in the second growth stage are given supplemental lighting.

[0077] Supplemental lighting refers to the use of electrical energy converted into light energy to provide additional illumination to fast-growing crops in low-light or no-light conditions, allowing them to grow with more sunlight. This is especially important during the seedling stage, when fast-growing crops have a long growth cycle but low sunlight requirements; precise supplemental lighting can shorten the seedling period and accelerate the crop's entry into its vigorous growth phase. Specifically, as follows... Figure 5aAs shown, a supplemental lighting device 6004 is installed in a multi-layer rack 6000 to provide supplemental lighting for fast-growing crops in low or no light conditions. Supplemental lighting can also be provided by an externally fixed supplemental lighting device 6004 to provide supplemental lighting for fast-growing crops in low or no light conditions. The supplemental lighting device can be an illumination lamp. The placement of the supplemental lighting and the supplemental lighting device 6004 are exemplary. For seedling crops, since seedlings occupy a small proportion of the planting space, precise supplemental lighting can save on supplemental lighting costs. When the crops grow larger, using a certain angle of incidence allows for the utilization of most of the supplemental light, thus reducing the requirement for precise coverage. Specifically, different planting areas can be used at different stages, such as multiple first growth zones, each using different lighting methods; different illumination lamps can be turned on at different stages; or some lamps can simply be used, in a cost-effective manner. Furthermore, for high-value fast-growing crops, supplemental lighting can also be provided in the second growth zone.

[0078] The determination of whether the first and second growth zones are in low light or no light can be made by using a light meter or experience, combined with the growth environment, type, and region of the fast-growing crop. Further details will not be provided here.

[0079] Carbon dioxide is replenished in the first and / or second growth zones using a carbon dioxide replenishment device 7000. Specifically, carbon dioxide generated at coal yards, wineries, or power plants is transported to the farm's carbon dioxide storage equipment via a carbon dioxide transport vehicle or dedicated carbon dioxide conveying equipment. One end of the carbon dioxide replenishment device is connected to the output end of the carbon dioxide storage equipment, allowing carbon dioxide from the equipment to be transferred to the replenishment device through its output end. The carbon dioxide is then output through an opening 7001 into the space of the first and / or second growth zones to replenish the carbon dioxide for fast-growing crops, thereby accelerating their growth.

[0080] The aforementioned carbon dioxide supplementation can be done once or multiple times. It is well known that the growth of fast-growing crops mainly depends on sunlight, water, and carbon dioxide, with other factors including soil nutrients. For fast-growing crops, rapid growth is paramount, which consumes significant amounts of carbon dioxide and soil nutrients. Besides traditional fertilization, supplementing with carbon dioxide is a crucial option for achieving rapid growth. Because carbon dioxide is denser than air, it is generally supplemented slowly, naturally dispersing outwards from the ground. Therefore, to improve carbon dioxide utilization efficiency, such as… Figure 6bGenerally, carbon dioxide is supplemented at the top of the crop, with the opening 7001 positioned at the top. However, for outdoor planting, the biggest challenge is that wind disperses carbon dioxide into the environment. In this case, the opening 7001 can be positioned in the middle to balance leaf concentration and reduce environmental diffusion loss. Alternatively, the opening 7001 can be placed at the bottom for slow carbon dioxide absorption. The specific choice depends on a comprehensive consideration of installation cost and environmental impact, and will not be elaborated further. In this invention, the carbon dioxide supplementation device can be a pipe, with one end vertically installed at the output end, and the opening located at at least one position at the top, middle, and bottom of the pipe.

[0081] Supplementing carbon dioxide in greenhouse cultivation minimizes waste, as the carbon dioxide is confined within the greenhouse regardless of the method used. However, in open cultivation, wind influence and lateral diffusion are significant problems. For fast-growing crops, especially those used for feed or energy production, greenhouse cultivation is relatively less cost-effective, and the potential loss of carbon dioxide during open cultivation requires careful consideration. Therefore, firstly, carbon dioxide supplementation should be carried out at appropriate times, such as when there is ample sunlight or high chlorophyll-to-carbon dioxide conversion efficiency, especially when wind speed is low or there is no wind. Secondly, this measure should be adopted as much as possible in large-scale field cultivation (e.g., thousands or tens of thousands of acres), so that even if diffusion occurs, it remains mainly concentrated within the planting area. Thirdly, when the first and / or second growth areas are cultivated in an open manner, carbon dioxide leakage prevention devices should be installed in both areas. These devices include second ground stakes, leakage prevention plates, and / or membranes, with the leakage prevention plates and / or membranes installed between adjacent second ground stakes.

[0082] A carbon dioxide leak prevention device 8000 is used to reduce carbon dioxide leakage. Specifically, as follows... Figure 6a As shown, taking the second growth zone 2100 as an example, carbon dioxide is supplied by a carbon dioxide replenishment device 7000, and a carbon dioxide leakage prevention device 8000 reduces carbon dioxide diffusion or wind-induced carbon dioxide loss from the planting zone 2100. The carbon dioxide leakage prevention device 8000 includes second ground stakes 8100, a leakage prevention plate, and / or membrane 8200. The leakage prevention plate and / or membrane 8200 are installed between adjacent second ground stakes 8100 to reduce carbon dioxide leakage. Carbon dioxide replenishment can be done once or multiple times, or even continuously at low doses. Furthermore, the height of the leakage prevention plate and / or membrane 8200 should be the same as, or higher than, the height of the fast-growing crops in the first growth zone or the second growth zone.

[0083] As described above, planting can be done outdoors or in a greenhouse, or for a period of time in an open environment (warm season) and a period of time in a greenhouse (cold season). Alternatively, to reduce the seedling growth period, when the crop seedlings and / or harvested crops are transported to the first growth zone, the first growth zone is placed in a greenhouse for agricultural planting. After the seedlings are slightly larger, they are moved to the first growth zone outdoors. This increases the overall utilization rate of sunlight, without specific limitations. If all planting is done in greenhouses, traditional northern planting yields 3-4 harvests (taking giant reed grass as an example). Using the method of this invention, it can be increased to 12 harvests and the corresponding land utilization rate (if a greenhouse plus traditional methods are used, only 6 harvests are still possible). Taking the multi-layer trellis method and traditional northern planting of 3 harvests as an example, the overall efficiency improvement rate is calculated as follows: The number of harvest stubble can be increased by 2.91 times, and the overall efficiency improvement rate reaches 191%, which has great potential for planting on wasteland in the north. The calculation of 8.73 is as described in the previous implementation method.

[0084] This invention separates fast-growing crops in their slow-growth and fast-growth phases. Specifically, it separates fast-growing crops in their seedling and vigorous growth phases. When fast-growing crops have lush foliage and are in their vigorous growth phase with strong photosynthesis, a transportable planting device is deployed in the second growth zone using a first spacing. After harvest, when crops have no foliage, or are in the germination or seedling stage with slow growth and low sunlight utilization, they are grouped together and even stacked. A second spacing is then used to deploy the transportable planting device in the first growth zone to improve the land's sunlight utilization rate. Using this method, the number of harvests in the second growth zone can be doubled. That is, using the traditional planting method, the total number of harvests in the second growth zone in a year is 6, while using the planting method of this invention, the total number of harvests in the second growth zone in a year is 12, an overall increase of more than 30% (refer to X1, X2). In northern regions, when combined with greenhouse planting, the overall number of harvests can be increased by more than 50% (refer to X3), and the problem of overwintering perennial crops can be solved, thereby significantly increasing the economic value of fast-growing crops.
