Description

Technical Field

[0001] This invention belongs to the field of cycad cultivation technology, and specifically relates to a cycad cultivation method and a crop harvesting device between ridges. Background Technology

[0002] Stachys aegyptium, also known as pagoda vegetable, snail vegetable, sweet dew seed, ground silkworm, and silver bar, can be cultivated as a monoculture or intercropping. Monoculture reduces the final yield, so farmers often use intercropping to make full use of land resources and increase profits. When intercropping, the planting and maturity time of suitable crops between the rows are generally selected. Typically, the first crop is a short-stalked crop such as wheat or broad beans, or a tall-stalked crop such as early-maturing corn. After the tall-stalked crops are harvested, the second crop is planted between the rows. The crops are mostly leafy vegetables such as cabbage, kale, spinach, and coriander, or root vegetables such as carrots and radishes. However, due to intercropping issues, crops between ridges are usually harvested or sown manually, which is labor-intensive and inefficient. Intercropping also dilutes the supply of soil nutrients, which can easily lead to insufficient supply of nutrients needed for the growth of Stachys edulis, resulting in reduced yield. At the same time, during the tuber enlargement period, soil covering the sides of the ridges usually requires manual covering, and the temperature is high at this time, making it easy for moisture to escape, resulting in insufficient water for the growth of Stachys edulis. Summary of the Invention

[0003] Therefore, it is necessary to provide a method for planting *Symplocos cuspidatum* and a harvesting device for crops between ridges, which addresses the problem that while harvesting crops between ridges, it is necessary to manually cover the sides of the *Symplocos cuspidatum* ridges with soil, and that the high temperature during the soil covering season makes it easy for moisture to be lost, resulting in insufficient water for the growth of *Symplocos cuspidatum*.

[0004] To achieve the above objectives, the present invention adopts the following solution:

[0005] A method for cultivating *Cynanchum paniculatum* includes site selection and ridging, application of base fertilizer, and the following steps:

[0006] Step S30. Planting the first crop: During the sowing period, plant the first crop between the rows;

[0007] Step S40. Planting of Stachys aegyptium: During the period of intercropping the first crop between the ridges, the tubers of Stachys aegyptium are planted on the ridges using a single tuber per hole planting method;

[0008] Step S50. Harvesting and covering with soil: In the early stage of tuber enlargement of *Symplocos edulis*, the first crop is harvested, and soil is covered on both sides of the ridge at the same time. The soil covering height is not less than the height of the ridge, and the straw crushed material of the first crop of short-stalked crops is laid on the sides of the ridge after the soil covering is completed.

[0009] Step S60. Planting the second crop: Immediately after the first crop is harvested, the seeds of the second crop are planted between the rows using machinery or manually.

[0010] Step S70. Harvesting of Stachys edulis and the second crop: During the Stachys edulis harvesting period, Stachys edulis and the second crop are harvested.

[0021] The technical solution adopted in this application can achieve the following beneficial effects:

[0022] 1. By using mechanical harvesting of inter-row crops, the labor efficiency in the grass-silkworm intercropping production mode has been effectively improved, and problems such as high labor intensity, low recycling rate of intercropped crop straw, and the need for mechanized sowing of the second crop have been solved.

[0023] 2. By crushing or covering the sides of the ridges with the straw of the first crop, a protective layer is formed, which reduces the water loss of the soil in the ridges during the later stages of growth, improves water-saving efficiency and the resource utilization efficiency of field waste, and helps to increase the soil organic matter content.

[0024] 3. By covering the sides of the ridge with soil, the volume of the ridge is increased, thereby increasing the space for the growth and expansion of the *Cymbidium goeringii* tubers, thus improving the yield and quality of *Cymbidium goeringii* products. Attached Figure Description

Detailed Implementation

[0031] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings. Preferred embodiments of this application are shown in the drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this application.

[0032] It should be noted that when a device is considered to be "connected" to another device, it can be directly connected to the other device or there may be an intervening device present. The terms "inside," "top," "upper," "lower," "above," "below," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0034] This application provides a method for cultivating *Polygonum cuspidatum*, including the following steps:

[0035] Step S10. Site selection and ridging: Select a sunny, fertile site with deep, loose soil and a low water table; turn the soil and make ridges, with a ridge width of 0.8 to 1.2 meters, a ridge height of 0.15 to 0.25 meters, and a furrow width of 0.7 to 2 meters;

[0036] Step S20. Apply base fertilizer: Turn the base fertilizer into the ridges made in step S10;

[0037] Specifically, *Symplocos edulis* is a short-day perennial herb that prefers moist conditions but is susceptible to waterlogging, and thrives in warm environments but is intolerant of high temperatures. It is best planted in deep, well-drained, loose, fertile sandy loam soil rich in organic matter. It should not be planted in clay soil and should not be continuously cropped in the same location. The above-ground parts of *Symplocos edulis* die after frost, but the underground tubers are highly cold-resistant and can overwinter naturally in the soil. Sprouting begins when the soil temperature stabilizes above 8℃. The optimal temperature for vigorous growth of the above-ground parts is 20℃ to 24℃. From early July, the plant transitions from vegetative to reproductive growth, flowering and producing underground stolons. Above-ground growth slows in September, while the terminal nodes of the stolons begin to swell and form tubers. By mid-October, the tubers are fully grown, and the above-ground parts die after frost.

[0038] Base fertilizer can generally be applied in conjunction with the previous year's autumn plowing per hectare. 2 Apply 22,500–30,000 kg of well-rotted farmyard manure and 750 kg of superphosphate or 300 kg of diammonium phosphate. After mechanically tilling the land to a depth of 0.25–0.30 meters, irrigate thoroughly in winter. Before planting and ridging, apply fertilizer per hectare. 2 Apply 750-900 kg of NPK (N:P2O5:K2O = 15:15:15) compound fertilizer and 1200-1500 kg of bio-organic fertilizer.

[0039] Step S30. Planting the first crop: During the planting period, the seeds of the first crop are sown mechanically or manually between the rows; the first crop in this application is wheat, but the stalk crops can also be short-stalk crops such as broad beans and peas or tall-stalk crops such as early-maturing corn.

[0040] Spring wheat should be sown in furrows between rows (planting period is March). Select compact, disease-resistant, and high-yielding varieties such as Ningchun 4 and Ningchun 50. Sow 2 to 10 rows with a row spacing of 0.15-0.2 meters and a seeding rate of 300 kg / hm². 2 Up to 330 kg / hm 2 (When intercropping broad beans, peas, or other legumes between rows, begin sowing broad beans or peas between rows in mid-to-late March. Suitable broad bean varieties include Qinghai No. 3 and Qinghai Large Broad Bean, with a sowing rate of 135 kg / hm².) 2 Up to 165 kg / hm 2 The row spacing is 0.2 meters, and the plant spacing is adjustable. Sow one seed per hole at a depth of 0.05 to 0.06 meters, in 2-9 rows. Suitable pea varieties include Zhongwan No. 2 and Zhongwan No. 4. The sowing rate is 120 kg / hm². 2 Up to 150 kg / hm 2 Sow 2 to 4 seeds per hole, at a depth of about 0.05 meters, with a row spacing of 0.15 to 0.2 meters and an adjustable plant spacing, sowing 2 to 10 rows.

[0041] Step S40. Planting of Stachys aegyptium: During the first crop intercropping period in March, plant Stachys aegyptium tubers (seeds) on the ridges, using a single tuber per hole;

[0042] The main method of cultivating *Symplocos edulis* is through asexual reproduction using tubers. In the first year, seed production is not carried out in autumn and winter; the tubers are left in the ground for natural overwintering and storage. The following spring, after the soil thaws, the tubers are harvested for transplanting. Generally, plots are selected where there are no viral diseases or root rot in the current year, and where the plants are growing well and uniformly. Normal field management, such as winter irrigation, is used. Seeds are harvested the following spring after the soil thaws but before the tubers sprout. Sowing begins in early to mid-March when the soil temperature is above 8℃. Three to four rows are planted on the ridges, with an average row spacing of 0.25 to 0.30 meters and a plant spacing of about 0.20 meters. Sowing is done by dibbling, with holes 0.05 to 0.07 meters deep. Each hole contains one uniform, disease-free, undamaged, and healthy tuber, with an average weight of 4 to 5.5 grams. The tubers are then covered with soil. (If some tubers have rotted during winter storage, before sowing, a quick treatment with a moist soil dressing method can be performed using 70% mancozeb wettable powder, 75% chlorothalonil wettable powder, 58% metalaxyl-mancozeb wettable powder, or 50% carbendazim (the dosage is approximately 0.2% of the tuber weight). The sowing rate is 450 kg / hm.) 2 Up to 825 kg / hm 2 ).

[0043] Step S50. Harvesting and covering with soil: In the early stage of tuber enlargement of *Cymbidium goeringii*, the first crop is harvested by machine or manually. At the same time, soil is covered on both sides of the ridge, with the soil covering height not less than the ridge height. The crushed straw of the first crop of short-stalked crops is then laid on the sides of the ridge after the soil covering is completed.

[0044] Wheat is generally harvested starting in early July (which is the early stage of tuber enlargement for cycads). When intercropping wheat, a small harvester or manual harvesting can be used. Manually harvested wheat requires secondary processing, as both the wheat ears and straw need to be transported out of the field. To improve efficiency and make full use of the wheat straw, mechanical harvesting is used to collect the wheat ears and pile the crushed wheat straw on the side of the ridge after it has been covered with soil.

[0045] Meanwhile, the growth of underground stolons and tubers is limited by the fixed volume of the ridges, restricting their further growth and expansion. By manually lifting the stems and leaves of the *Cynanchum paniculatum* on both sides of the ridge and mechanically removing soil from the furrows and covering the ridges, the volume of the ridges is increased. This expands the growth space for the underground stolons and tubers, allowing them to continue growing and expanding towards both sides of the ridge, thereby improving the yield and quality of *Cynanchum paniculatum*. After covering with soil, the crushed straw from the first crop is used to cover the ridge sides, forming a protective layer. This reduces water loss from the soil within the ridges during the later stages of growth, improving water-saving efficiency and the resource utilization efficiency of field waste, and also helps increase soil organic matter content.

[0046] During the planting period, it is necessary to strengthen field management of fertilizer and water. When using furrow irrigation, take advantage of soil moisture conditions. In early to mid-April, the grasshoppers and intercropped wheat and broad beans will successively germinate and emerge. Combine the first irrigation of wheat with topdressing at 225 kg / hm². 2 Apply a nitrogen, phosphorus, and potassium (N:P2O5:K2O = 15:15:15) ternary compound fertilizer, followed by 4-5 irrigations. Harvest wheat and other intercropped crops in early to mid-July after they mature. Irrigate again in mid-July. Avoid large irrigations during the hottest days of summer to prevent seedling death. Apply 180 kg / hm² of nitrogen, phosphorus, and potassium (N:P2O5:K2O = 20:10:20) ternary compound fertilizer as a top dressing. 2 Up to 225 kg / hm 2 In mid-August, during the vigorous growth period of the underground stolons of *Lithops*, apply 225 to 300 kg / hm² of NPK (N:P₂O₅:K₂O = 20:10:20) compound fertilizer with irrigation. 2 In early September, during the tuber enlargement period, apply 225 to 300 kg / hm² of NPK (N:P₂O₅:K₂O = 15:15:15) compound fertilizer with irrigation. 2During the seedling stage, manual weeding should be carried out 2 to 3 times. After July, during the vigorous growth period, manual weeding should be carried out 1 to 2 times. If drip irrigation is used, the total amount of fertilizer should remain basically the same, and the method is to apply small amounts of fertilizer multiple times with the drip irrigation water, controlling the fertilizer amount to per 1 hectare. 2 Each application should be around 75kg to 90kg. Care should be taken to control excessive plant growth and to coordinate the growth of the above-ground and underground parts.

[0047] Step S60. Planting the second crop: Immediately after the first crop is harvested, the seeds of the second crop are planted between the rows using machinery or manually.

[0048] The second crop is planted using mechanical or manual methods. The second crop is mostly leafy vegetables such as cabbage, kale, spinach, and coriander, or root vegetables such as carrots and radishes. The planting time is after the wheat harvest, which makes full use of land and light and heat resources and increases yield.

[0049] Step S70. Harvesting of Stachys edulis and the second crop: In October and November, Stachys edulis and the second crop are harvested by machinery or manual labor, packaged and stored in cold storage.

[0050] Harvesting begins around October after the first frost, when the above-ground parts of the *Cymbidium* plants turn yellow and wither. In ridge cultivation, loose sandy or sandy loam soils are ideal for mechanized harvesting. Harvesting is best when the relative moisture content of the soil at a depth of 0.1 to 0.2 meters is between 55% and 70%. After manually removing the main above-ground branches, timely mechanical harvesting is crucial. Existing harvesting equipment, to prevent excessive friction and damage to the tubers, typically uses two layers of vibrating screens to separate the tubers from larger clods and debris, allowing them to fall directly onto the soil surface. To prevent water loss, manual follow-up is necessary to collect and clean the tubers before bagging them. However, in loam and clay soils, where the soil is hard and prone to clumping, manual harvesting remains more suitable to minimize damage to the tuber skin.

[0051] While harvesting crops between ridges in the grass-and-silkworm intercropping model, soil can be covered on both sides of the grass-and-silkworm ridges, and the straw shreds of the first crop of short-stalk crops can also be covered at the same time. In addition to effectively improving labor efficiency and ecological effects, soil covering can increase the soil volume for tuber enlargement and growth, while covering with shredded straw can effectively reduce soil moisture loss in the later stages of growth, thus playing a role in water retention and increasing soil organic matter content.

[0052] The technical solution of the proposed method for cultivating *Polygonum cuspidatum* can achieve the following beneficial effects:

[0053] 1. By using mechanical harvesting of inter-row crops, the labor efficiency in the grass-silkworm intercropping production mode has been effectively improved, and problems such as high labor intensity, low recycling rate of intercropped crop straw, and the need for mechanized sowing of the second crop have been solved.

[0054] 2. By crushing or covering the sides of the ridges with the straw of the first crop, a protective layer is formed, which reduces the water loss of the soil in the ridges during the later stages of growth, improves water-saving efficiency and the resource utilization efficiency of field waste, and helps to increase the soil organic matter content.

[0055] 3. By covering the sides of the ridge with soil, the volume of the ridge is increased, thereby increasing the space for the growth and expansion of the *Cymbidium goeringii* tubers, thus improving the yield and quality of *Cymbidium goeringii* products.

[0056] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be described in further detail below.

[0057] Six mu of land suitable for planting *Cymbidium goeringii* was selected as experimental plots, and each plot was numbered in a 0.5 mu (numbered 1, 2, 3...11, 12) manner. The same field management was carried out on the twelve experimental plots (the field management mentioned above) to ensure that the soil was in the same condition and suitable for planting *Cymbidium goeringii*. *Cymbidium goeringii* of the same variety (local farm variety of Helan County) was selected and divided into 12 samples as seed samples.

[0058] Sowing method: Generally, sowing of *Symplocos edulis* begins in early to mid-March, with 3 rows planted on the ridges, an average row spacing of 25cm, and a plant spacing of 20cm. Sow by dibbling in holes 5cm deep, placing one uniform, disease-free, undamaged, and robust tuber per hole, ideally with an average weight of 4.0g. Cover with soil after sowing. If some tubers have rotted during winter storage, a quick treatment with a mild soil dressing (approximately 0.2% of the tuber weight) can be applied before sowing, using 70% mancozeb wettable powder, 75% chlorothalonil wettable powder, 58% metalaxyl-mancozeb wettable powder, or 50% carbendazim. Maintain a basic seedling density of 120,000 plants / hm². 2 The seeding rate is approximately 600 kg / hm². 2 .

[0059] Field Management: Fertilizer and water management utilizes soil moisture. In early to mid-April, the physalis and intercropped wheat will gradually germinate and emerge. Generally, the first irrigation is done in late April, with topdressing applied at 225 kg / hm². 2 Apply a nitrogen, phosphorus, and potassium (N:P2O5:K2O = 15:15:15) ternary compound fertilizer; irrigate twice, 10 days later; irrigate a third time in late May after the wheat has jointed; irrigate a fourth time in late June. Harvest the wheat in early to mid-July after it matures. In mid-July, irrigate again, applying 180 kg / hm² of nitrogen, phosphorus, and potassium (N:P2O5:K2O = 20:10:20) ternary compound fertilizer. 2In mid-August, during the vigorous growth period of the underground stolons of *Lithops*, apply 225 kg / hm² of NPK (N:P₂O₅:K₂O = 20:10:20) compound fertilizer with irrigation. 2 In early September, during the tuber enlargement period, irrigate for the last time and apply 225 kg / hm² of NPK (N:P₂O₅:K₂O = 15:15:15) compound fertilizer. 2 Cultivate and weed. During the seedling stage, cultivate and weed manually 3 times. After July, during the vigorous growth period, weed manually 2 times (if not intercropped, still irrigate and fertilize according to the time points).

[0060] Example 1:

[0061] Three experimental plots (1, 2, and 3) were selected. During the planting period, the experimental plots were mechanically ridged, and the *Symplocos edulis* was sown on the ridges using a single tuber planting method per hole (the sowing method described above was used).

[0062] After sowing, field management is carried out (using the above-mentioned field management methods) until the harvest season. The stachys gracilis is harvested, and three random selections are made, with 100 seeds selected each time to count the number of large fruits (length greater than 5cm and diameter greater than 1cm). The number and rate of large fruits of the stachys gracilis are calculated.

[0063] Example 2:

[0064] Three experimental plots, 4, 5, and 6, were selected. During the planting period, mechanical ridging was carried out on the experimental plots, and wheat was planted between the ridges (stalk crops can be intercropped with broad beans, wheat, corn, etc., with wheat being the best choice; wheat was used as the experimental sample in this example). After planting, the stachys plant was sown on the ridges using a single tuber planting method per hole.

[0065] After sowing, field management is carried out (the same field management methods as described above are used). During the early stage of tuber enlargement (early stage of tuber enlargement of *Symplocos edulis*), wheat is harvested and the yield is calculated. After harvesting, field management continues. During the harvest period (*Symplocos edulis* harvest period), *Symplocos edulis* is harvested, and 100 seeds are randomly selected three times. The number of large seeds (length greater than 5cm and diameter greater than 1cm) in each selection is counted, and the number and rate of large seeds are calculated.

[0066] Example 3:

[0067] Three experimental plots, 7, 8, and 9, were selected. During the planting period, mechanical ridging was carried out on the experimental plots, and wheat was planted between the ridges (stalk crops can be intercropped with broad beans, wheat, corn, etc., with wheat being the best choice; wheat was used as the experimental sample in this example). After planting, the stachys plant was sown on the ridges using a single tuber planting method per hole.

[0068] After sowing, field management is carried out (the same field management methods as described above are used). In the early stage of tuber enlargement (early stage of tuber enlargement of *Cymbidium goeringii*), wheat is harvested and the yield is calculated. After the wheat is harvested, soil is covered on both sides of the ridge by machine. After the soil is covered, field management continues.

[0069] Harvest the *Cymbidium goeringii* during the harvest period (harvest period of *Cymbidium goeringii*), and randomly select 100 seeds three times each time. Count the number of large seeds (length greater than 5cm and diameter greater than 1cm) in each selection, and calculate the number and rate of large seeds.

[0070] Example 4

[0071] Three experimental plots, 10, 11, and 12, were selected. During the planting period, mechanical ridging was carried out on the experimental plots, and wheat was planted between the ridges (the first crop is a stalk crop, and intercropping crops include broad beans, wheat, corn, etc., with wheat being the best. Wheat was used as the experimental sample in the example). After planting, the stachys plant was sown on the ridges using a single tuber planting method per hole.

[0072] After sowing, field management is carried out (the same field management methods as described above are used). During the early stage of tuber enlargement (early stage of tuber enlargement of *Symplocos edulis*), wheat is harvested and the yield is calculated. After the wheat is harvested, soil is covered on both sides of the ridge by machine. After the soil is covered, the second crop is planted (the second crop includes cabbage, radish, rapeseed, etc., preferably radish; radish is used in this example for the experiment). Field management continues after planting.

[0073] During the harvest period (grass worm harvest period), grass worms and radishes are harvested, and 100 grains are randomly selected three times each time. The number of large grains (grass worms with a length greater than 5cm and a diameter greater than 1cm or grade 3 or above) in each selection of grass worms is counted, and the number of large grains and the rate of large grains are calculated.

[0074]

[0075] Comparing Examples 1, 2, 3, and 4, Example 1, without intercropping, had the lowest large-fruit rate at 60.33%. Example 2, by intercropping one crop, further improved the large-fruit rate to 61.67%, but some plots remained vacant after intercropping, leaving room for further economic improvement. In Example 3, during intercropping, soil was covered during the early tuber enlargement stage of *Symplocos edulis*, increasing its growth space and inducing it to grow towards the covered area and enlarge its tubers, resulting in a large-fruit rate of 65.67%. Again, some plots remained vacant after intercropping, leaving room for further economic improvement. In Example 4, by covering the tubers with soil during tuber enlargement and then intercropping a second crop, the large-fruit rate increased to 67.67%, with no idle land, maximizing profits. Therefore, intercropping *Symplocos edulis* and then covering the tubers with soil during tuber enlargement results in the highest large-fruit rate and best performance.

[0076] See Figures 1 to 5 To achieve inter-row harvesting, ridge-side covering, and ridge-side mulching based on a method for cultivating *Symplocos edulis*, an inter-row crop harvesting device is provided, comprising: a body 100, a harvesting component 600, a soil-covering component 300, and a mulching component 400. Wheels 110 are provided on both sides of the body 100, and the wheels 110 drive the body 100 to reciprocate between the rows along the ridge sides. The harvesting component 600 is located at one end of the body 100 and is used to harvest the first crop that has matured between the rows. The soil-covering component 300 includes a loosening roller 310, a conveying plate 320, and a scraper 330. The loosening roller 310 is located at one end of the body 100 and is used to loosen the soil between the rows. The conveying plate 320... The end of the conveyor plate 320 is located behind the loosening roller 310 and penetrates the bottom of the machine body 100, and is connected to the side wall of the machine body 100. The other end of the conveyor plate 320 extends out of both sides of the machine body 100. The scraper 330 is located on both sides of the machine body 100 and behind the end of the conveyor plate 320 that extends out of the machine body 100. The covering assembly 400 includes a rod-type conveyor 410 and a rod-type laying member 420. One end of the rod-type conveyor 410 is located behind the harvesting assembly 600, and the other end extends out of both sides of the machine body 100 and is located behind the scraper 330. The rod-type laying member 420 is connected to the end of the rod-type conveyor 410 that is away from the harvesting assembly 600, and is used to change the laying direction.

[0077] Specifically, the harvesting component 600 uses, but is not limited to, harvesting devices such as wheat harvesters and straw cutters (only the front-end harvesting and transportation equipment of the machinery is required), and the soil covering component 300 uses, but is not limited to, tillage machinery such as tillers and soil looseners. All drive equipment is installed inside the machine body 100, and at least one transmission wheel and gear are installed on the wheels 110.

[0078] The loosening roller 310 is located at one end of the machine body 100 that travels and corresponds to the furrow. The loosening roller 310 is a tiller, but not limited to a soil turner. The loosening roller 310 is driven by a motor or transmission and is connected to the wheel 110 by means of friction wheel, belt, gear, etc. The conveying plate 320 is located behind the loosening roller 310 and is inclined upward. It penetrates into the machine body 100 from the bottom. The two ends of the conveying plate 320 are connected to the machine body 100 by auxiliary plates, etc. Scrapers 330 are provided on both sides of the machine body 100 and are located behind the end of the conveying plate 320. The scrapers 330 move with the machine body 100 to spread the soil and compact it on the side of the ridge.

[0079] Both ends of the loosening roller 310 are rotatably connected to the support frame of the n-shaped structure. The support frame is slidably connected to the machine body 100, and both ends of the support frame are equipped with telescopic cylinders. The side walls of the telescopic cylinders are fixedly connected to the machine body 100, and the telescopic cylinders can extend and retract vertically. By extending and retracting the telescopic cylinders, the loosening roller 310 moves up and down, thereby adjusting the height of the loosening roller 310 and the soil turning depth. The conveying plate 320 is located behind the loosening roller 310 and is slidably connected to the machine body 100. The soil turning depth and soil turning amount are adjusted by sliding the conveying plate 320 up and down.

[0080] Furthermore, the wheel 110 carries the machine body 100 into the ridge, and the harvesting component 600 is activated to harvest the wheat. The harvesting component 600 harvests the wheat ears and cuts off the wheat stalks. The cut wheat stalks are transported from the front end to the stalk laying component 420 by the stalk conveyor 410. At the same time, the soil loosening roller 310 located behind the harvesting component 600 loosens the soil and turns over and chops the wheat roots. The conveyor plate 320 scoops up a portion of the loosened soil and transports it to both sides of the machine body 100 and lays it on the ridge side. Then, the scraper 330 at the rear end of the conveyor plate 320 scrapes it flat and presses it down. At this time, the wheat stalks are placed on the ridge side by the stalk laying component 420, thereby covering the ridge side to achieve the following effect:

[0081] 1. By laying wheat straw on the sides of the ridges to form a protective film, direct sunlight on the soil is reduced, thereby slowing down the rate of water evaporation within the ridges and solving the problem of excessive water loss leading to water shortage in the phytocarpus.

[0082] 2. By setting up the harvesting component 600, the problem of low efficiency in manual harvesting is solved, while reducing labor intensity; by setting up the soil covering component 300, the soil between the rows is loosened and the wheat roots are exposed, solving the problems of difficulty in soil collection and subsequent sowing, while reducing the labor intensity of manual soil covering and improving work efficiency.

[0083] 3. By setting up a conveyor plate 320, soil can be transported and the soil height can be changed, making it simpler and more convenient to cover the soil on the side of the ridge.

[0084] Based on the above scheme, the conveyor plate 320 includes a shovel plate 321 and a conveyor belt 322. The shovel plate 321 is slidably connected to the machine body 100 and can slide up and down in the vertical direction. One end of the conveyor belt 322 is located at the end of the shovel plate 321 away from the loosening roller 310, and the other end of the conveyor belt 322 extends out of the machine body 100 on both sides adjacent to the loosening roller 310.

[0085] Furthermore, the conveyor belt 322 is provided with a drive pulley 323 and a driven pulley 324 at both ends. The two ends of the driven pulley 324 are connected to the two ends of the shovel plate 321. The drive pulley 323 is rotatably connected to the machine body 100, and the height of the drive pulley 323 from the ground is greater than the height of the driven pulley 324 from the ground.

[0086] Specifically, the two ends of the shovel plate 321 are slidably connected to the machine body 100 via auxiliary connecting plates, and the width of the shovel plate 321 is no greater than the width of the furrow, and also no greater than the width of the loosening roller 310; Option 1: The shovel plate 321 is inclinedly mounted on the auxiliary connecting plate, which is slidably connected to the inner wall of the machine body 100, and a telescopic rod is provided on the auxiliary connecting plate, which drives the auxiliary plate to slide up and down, thereby realizing the height adjustment of the shovel plate 321; Option 2: The two sides of the shovel plate 321 near the loosening roller 310 are slidably connected to the auxiliary connecting plate via telescopic rods, and the two sides of the other end of the shovel plate 321 extend into the auxiliary connecting plate and are connected to it. The rotating connection allows adjustment of the depth of the shovel plate 321 extending into the bottom of the furrow by extending or retracting the telescopic rod, thereby regulating the amount of soil removed. Baffles are installed on both sides of the conveyor belt 322 to prevent excessive soil removal from scattering from the sides. The driven wheel 324, located near the shovel plate 321, is rotatably connected to the inner wall of the machine body 100 via a sliding or fixed connection, depending on the installation method of the shovel plate 321 (sliding connection in option one, rotating connection in option two). The driving wheel 323 is higher than the driven wheel 324 above the ground (the driving wheel 323 is driven by a motor), thus raising the soil level and facilitating transportation. A guide plate is installed at the end of the conveyor belt 322 furthest from the shovel plate 321, extending out of the side wall of the machine body 100 to guide and cover the soil along the ridge side.

[0087] By setting a transmission wheel at one end of the drive wheel 323 and connecting the transmission wheel to the wheel 110 via a belt, the rotation speed of the transport belt 322 can be adjusted by adding a speed-changing wheel at one end of the wheel 110 or the drive wheel 323. This makes the operation simpler and more convenient, and reduces the need for motor installation.

[0088] In a preferred embodiment, in order to prevent damage to the stems and leaves of the silkworm, a seedling support component 200 is also included. The seedling support component 200 is disposed on both sides of the machine body 100 and moves with the machine body 100 to straighten the stems and leaves of the silkworm on the ridge from a creeping state to a standing state.

[0089] Specifically, the seedling support component 200 adopts, but is not limited to, an angled structure such as an arc-shaped plate or an inclined plate with a gradually changing angle. The seedling support component 200 is set above the soil covering component 300. The seedling support component 200 extends into the gap of the stems and leaves of the cycad by its front end, and lifts the stems and leaves of the cycad away from the side of the ridge by the seedling support plate 220, thereby solving the problem of damage to the stems and leaves of the cycad caused by soil covering, pressing and covering with wheat straw.

[0090] Based on the above scheme, the seedling support component 200 includes an extension plate 210, a transition plate 220, and a straightening plate 230. One side of the extension plate 210, the transition plate 220, and the straightening plate 230 are all hinged to the side wall of the machine body 100, and the other side is inclined upward. One end of the extension plate 210 extends out of the machine body 100 near the loosening roller 310 and can extend into the gap between the side of the ridge and the stems and leaves of grass, stone, and silkworm. One end of the transition plate 220 is fixedly connected to the end of the extension plate 210 away from the loosening roller 310. One end of the straightening plate 230 is connected to the end of the transition plate 220 away from the extension plate 210, and the other end extends out of the machine body 100 away from the loosening roller 310.

[0091] Specifically, the length of the insertion plate 210 can be adjusted according to the crawling conditions of the grasshopper, and can be extended using detachable methods such as bolts; for example, one side of the insertion plate 210 can be connected to the side wall of the machine body 100 using a pivot 424 or a hinge (if the pivot 424 is used, a gear and a locking plate are installed to fix the angle, the gear is set at both ends of the insertion plate 210, and the locking plate is hinged below the pivot 424, controlling the angle of the insertion plate 210 through locking; if a hinge is used, a limiting hinge is used to control the connection between the insertion plate 210 and the side wall of the machine body 100); the straightening plate 230 and One side of the transition plate 220 is connected to the extension plate 210 in the same way. The transition plate 220 is set between the extension plate 210 and the straightening plate 230. The tilt height of the extension plate 210, the transition plate 220 and the straightening plate 230 away from the machine body 100 gradually increases. The end of the straightening plate 230 away from the transition plate 220 extends out of the scraper 330. By gradually increasing the angle, when the machine body 100 moves, the stems and leaves of the codling silkworm follow the angle change of the seedling support component 200 to gradually straighten and move away from the side of the ridge, thereby solving the problem of covering the stems and leaves of the codling silkworm when covering with soil.

[0092] In a preferred embodiment, the scraper 330 includes a leveling part 331 and a pressing part 332. One end of the leveling part 331 is hinged to the side wall of the machine body 100 and can rotate up and down in the vertical direction along the hinge. The pressing part 332 forms an angle of 90° to 180° with the side of the leveling part 331 near the bottom of the ridge and can slide up and down along the leveling part 331.

[0093] Specifically, the leveling part 331 of the scraper 330 is perpendicular to the side of the ridge. A protruding ear plate is provided in the middle of one end of the leveling part 331. The ear plate has a through hole and a locking strip is hinged to the bottom of the ear plate. A semi-circular plate is provided in the corresponding part of the machine body 100. The semi-circular plate has several teeth on its periphery and several round holes. The ear plate is connected to the semi-circular plate by a rotating shaft or a pin. The height of the scraper 330 is adjusted by connecting different round holes, and the scraper is adjusted by locking the locking strip onto the teeth. The tilt angle is 330°; a groove is provided on the side of the flattening part 331 near the pressing part 332, and a nut is provided on the top of the groove. The pressing part 332 is L-shaped (the degree of compaction can be adjusted by changing the pressing part 332 at different angles), and a protrusion is provided on the side near the flattening part 331. The protrusion is embedded in the groove and is connected to the pressing part 332 through a screw that passes through the nut and through a bearing. The pressing part 332 can be moved up and down by rotating the screw, making the operation simpler and more convenient.

[0094] In the above scheme, the rod-type transmission component 410 includes a first guide plate 411, a first conveyor belt 412, and a second guide plate 413. One end of the first guide plate 411 is disposed below the harvesting assembly 600 and connected to the machine body 100. The first conveyor belt 412 is disposed at the end of the first guide plate 411 away from the harvesting assembly 600 and is drively connected to the harvesting assembly 600. The second guide plate 413 is disposed at the end of the first conveyor belt 412 away from the first guide plate 411, and the end of the second guide plate 413 away from the first conveyor belt 412 is connected to the rod-type laying component 420.

[0095] Specifically, the first guide plate 411 is fixedly connected inside the machine body 100, and one end of the first guide plate 411 is flush with one end of the first conveyor belt 412. The first conveyor belt 412 is laid out at an angle upward, and the end away from the first guide plate 411 is flush with the second guide plate 413. The second guide plate 413 is horizontally set and placed on one side of the pole laying component 420. The first guide plate 411 is used to gather the wheat straw and put it into the first conveyor belt 412, and the second guide plate 413 is used to change the direction of the wheat straw on the first conveyor belt 412 so that it remains horizontal. The transportation method is simple and convenient, and it is easy to lay out.

[0096] Based on the above scheme, the rod-type laying component 420 includes a second conveyor belt 421 and a third guide plate 422. The second conveyor belt 421 is disposed at one end of the second guide plate 413 and forms an angle of 0° to 90° with the extension direction of the first conveyor belt 412. The third guide plate 422 is obliquely disposed at the end of the second conveyor belt 421 away from the second guide plate 413 and extends out of the side wall of the machine body 100 and is in contact with the side wall.

[0097] Specifically, the second conveyor belt 421 is arranged perpendicularly to the first conveyor belt 412 (the angle is selected according to the specific layout, with perpendicular arrangement being optimal). The second guide plate 413 has a trough, with its two ends connected to the end of the first conveyor belt 412 and one side of the beginning of the second conveyor belt 421, respectively. The second guide plate 413 is parallel to the second conveyor belt 421 and on the same horizontal plane. When the straw is tilted and conveyed to the second guide plate 413, its weight causes it to change from an inclined state to a horizontal state and fall onto the second conveyor belt 421. The second conveyor belt 421 and the first conveyor belt 412 are connected... The rotation direction is changed and transmission is achieved through bevel gear meshing, reducing the need for motor installation. The third guide plate 422 is located at the end of the second conveyor belt 421, with the other end extending out of the machine body 100. The third guide plate 422 and the second conveyor belt 421 are set at an angle of 120° to 180°, and the angle is as close as possible to the inclination angle of the ridge side. When the wheat straw enters the third guide plate 422 from the second conveyor belt 421, the transport angle is changed, and with the help of inertia and the thrust of the wheat straw behind, it flies off the third guide plate 422 and falls onto the ridge side, thus completing the work of covering the ridge side with wheat straw.

[0098] Based on the above scheme, in order to achieve the purpose of integrated harvesting and sowing, a sowing component 500 is also included. The sowing component 500 is located at one end of the machine body 100 away from the harvesting component 600 and is used to sow the second crop.

[0099] Specifically, the sowing component 500 uses a common seeder. After the harvesting component 600 located at the front of the machine body 100 harvests the wheat, the loosening roller 310 loosens the soil between the rows and cuts the wheat roots. The conveyor plate 320 scoops up the required soil and indirectly levels the soil between the rows. The seeder located at the rear of the machine body 100 directly sows the seeds in the prepared soil, thereby achieving integrated harvesting and sowing, reducing labor costs and improving work efficiency.

[0100] The above-described embodiments merely illustrate the device layout of this application, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make several adjustments and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
