Description

Technical Field

[0001] The present invention belongs to the field of agriculture, and particularly relates to a rotation planting method for tobacco, soybeans and corn. Background Art

[0002] Tobacco is an important cash crop, and the planting and production of tobacco have contributed to economic development. At present, China has become the world's largest tobacco manufacturing country, and its annual manufacturing volume accounts for about one-third of the global output. Due to the huge annual tobacco output in China and years of planting and harvesting, currently, China's tobacco output has tended to be saturated or even there is an overproduction, and the income of farmers from growing tobacco has begun to decline. At the same time, since a large amount of land area is occupied by tobacco, the planting area of other crops (such as soybeans) has inevitably shrunk, and the purchase price of other crops has also started to rise. Therefore, when the income from growing tobacco decreases, the income from growing other crops is gradually valued. In addition, in order to avoid the excessive planting area of tobacco affecting the yield of other crops and endangering food security, the relevant departments are also actively promoting and subsidizing farmers to grow other crops.

[0003] In order to increase the yield of other crops, the applicant proposed a planting method of intercropping soybeans + tobacco. That is, after the tobacco grows to a certain height, soybeans are sown on the side of the tobacco, so that the tobacco and soybeans grow together, realizing the mixed planting of tobacco and soybeans.

[0004] However, the inventor found in practice that the above planting method has some deficiencies, which are specifically reflected in the following two points. First, only soybeans and tobacco can be planted, and the types of harvested crops are few; second, due to the relatively large shading area of tobacco itself, and the tobacco in other ridges will also shade, the soybeans planted on the side of the tobacco cannot receive good light, easily resulting in light starvation phenomenon, and the yield of soybeans is low. Summary of the Invention

[0005] The present invention provides a rotation planting method for tobacco, soybeans and corn, which can increase the yield of soybeans and obtain more varieties of crops.

[0006] In order to achieve the above object, the present invention provides a rotation planting method for tobacco, soybeans and corn, including the following steps;

[0007] S1: Divide the land into a first planting ridge and a second planting ridge;

[0008] S2: Plant tobacco in the first planting ridge and sow spring soybeans in the second planting ridge;

[0009] S3: After the spring soybeans mature, harvest the spring soybeans in the second planting ridge, transplant corn seedlings into the second planting ridge, pick the lower leaves of the tobacco in the first planting ridge, and sow autumn soybeans on the side of the tobacco;

[0010] S4: After the tobacco matures, pick all the leaves of the tobacco in the first planting ridge;

[0011] S5: Harvest the corn in the second planting ridge;

[0012] S6: Harvest the autumn soybeans in the first planting ridge.

[0013] Through the planting method disclosed in this solution, spring soybeans and autumn soybeans can be harvested. Compared with the previous sowing method, the yield of soybeans is higher. In addition, after the spring soybeans are harvested, corn is continuously planted in the second planting ridge. When the corn matures, the corn is harvested. Compared with the previous sowing method, more crop varieties are harvested.

[0014] Preferably, it includes S0: Plant fertilizer-assisted plants and rot the roots and stems of the fertilizer-assisted plants in the land. By rotting the roots and stems of the fertilizer-assisted plants in the land, the nutrient content in the land is higher, which is beneficial to promoting the growth of subsequent crops.

[0015] At the same time, for the convenience of subsequent mechanical operations, in this solution, it is preferred that in S1, the first planting ridge and the second planting ridge are arranged at intervals in sequence.

[0016] Preferably, for the convenience of mechanical work and reducing manual intervention, in this solution, it is preferred that in S3, first, after the spring soybeans in the second planting ridge mature, harvest the spring soybeans; then, mechanically sow autumn soybeans on the side of the tobacco; and then transplant the corn seedlings into the second planting ridge.

[0017] In this solution, the spring soybeans are harvested first, so that there will be no crops on both sides of the first planting ridge affecting mechanical operation. Then, it is convenient to mechanically sow autumn soybeans on the side of the tobacco, reducing the manual workload. After the autumn soybeans are sown, transplant the corn seedlings into the second planting ridge.

[0018] Through the above process in this solution, the manual workload can be greatly reduced and mechanical operation is convenient. At the same time, by transplanting corn seedlings, the growth cycle of corn in the second planting ridge is shortened, avoiding entering the cold season due to too long a growth cycle.

[0019] Preferably, for labor saving, in this solution, it is preferred that in S3, the spring soybeans in the second planting ridge are harvested by machine and the spring soybean stalks are pulled out.

[0020] To save labor, in step S3 of this solution, the corn seedlings are transplanted into the second planting ridge by machinery.

[0021] Preferably, to avoid damage to the autumn soybeans on both sides by the mechanical device when mechanically removing the tobacco stalks later, in step S3 of this solution, it is preferred that the autumn soybeans are evenly sown on the sides of the tobacco. The autumn soybeans evenly located on the sides of the tobacco have a certain distance from the tobacco stalks when the tobacco stalks are mechanically removed later, and the mechanical device has less impact on the autumn soybeans on both sides.

[0022] To increase the yield of autumn soybeans, in step S3 of this solution, the autumn soybeans are sown on both sides of the tobacco. The autumn soybeans on both sides can be harvested, thus obtaining more autumn soybeans.

[0023] Preferably, to avoid shading between the corn seedlings, in step S3 of this solution, when transplanting the corn seedlings, the leaf directions of the corn seedlings are made parallel to each other. Since the growth direction of the corn leaves does not change. Therefore, when transplanting the corn seedlings with their leaf directions parallel to each other, when the corn grows up, the corn leaves are also in a parallel state to each other, and there will be no shading between the corns, and the yield of the corn can be higher.

[0024] Preferably, to reduce the shading of the autumn soybeans by the corn leaves on both sides, in step S3 of this solution, it is preferred that the planting position of the autumn soybeans in the first planting ridge is directly opposite the gap between the corn seedlings in the second planting ridge.

[0025] Preferably, to increase higher economic value, in steps S4 and S5 of this solution, the corn is fresh corn. Fresh corn can be used to make silage or for consumption. The utilization rate of fresh corn is higher.

[0026] To increase economic value, in step S6 of this solution, the autumn soybeans harvested from the first planting ridge are green beans.

[0027] Preferably, to improve the utilization rate of the corn stalks, in step S5 of this solution, the harvested corn and the removed corn stalks are uniformly made into silage. After the corn stalks are made into silage, the corn stalks will not remain in the second planting ridge.

[0028] To avoid the mechanical device from affecting the yield of the autumn soybeans, in step S6 of this solution, after harvesting the autumn soybeans in the first planting ridge, the tobacco stalks are then mechanically removed. In this solution, when the tobacco stalks are mechanically removed, the autumn soybeans have already been harvested, so the mechanical device will not affect the yield of the autumn soybeans.

[0029] Preferably, in order to harvest more crop varieties, in step S1 of Solution 4 of the present solution, it further includes a third planting ridge and a fourth planting ridge, and the first planting ridge, the second planting ridge, the third planting ridge, and the fourth planting ridge are arranged in sequence;

[0030] In step S2, tobacco is also planted in the first planting ridge and the third planting ridge, and spring soybeans are sown in the second planting ridge and the fourth planting ridge;

[0031] In step S3, after the spring soybeans are mature, the spring soybeans in the second planting ridge and the fourth planting ridge are harvested, corn seedlings are transplanted into the second planting ridge, buckwheat is sown in rows in the fourth planting ridge, the lower leaves of the tobacco in the first planting ridge and the third planting ridge are picked, and autumn soybeans or buckwheat are sown on the side of the tobacco;

[0032] In step S4, after the tobacco is mature, all the leaves of the tobacco in the first planting ridge and the third planting ridge are picked;

[0033] In step S5, the corn in the second planting ridge is harvested, and the buckwheat in the fourth planting ridge is harvested;

[0034] In step S6, the autumn soybeans or buckwheat in the first planting ridge and the third planting ridge are harvested.

[0035] In Solution 4 of the present solution, by setting the third planting ridge and the fourth planting ridge, buckwheat can be planted in the fourth planting ridge, enabling the grower to harvest buckwheat. At the same time, corn and buckwheat are located in the second planting ridge and the fourth planting ridge respectively, so both corn and buckwheat can grow normally. Solution 4 of the present solution can harvest soybeans, tobacco leaves, buckwheat, and corn simultaneously, harvesting more types of crops.

[0036] The beneficial effects of the present invention are as follows: First, through the planting method disclosed in the present solution, it can harvest spring soybeans and autumn soybeans, and the yield of soybeans is higher compared to the previous sowing methods.

[0037] Second, after the spring soybeans are harvested, corn is continuously planted in the second planting ridge. When the corn is mature, corn is harvested again. Compared with the previous sowing methods, more types of crops are harvested. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] It should be noted that all actions of obtaining signals, information or data in this application are carried out on the premise of complying with the corresponding data protection regulations and policies of the country where it is located and obtaining the authorization given by the owner of the corresponding device.

[0050] In the present disclosure, unless otherwise stated, the orientation terms such as "inside, outside" are defined according to the own contour of the corresponding component. The terms such as "first, second" used in the present disclosure are used to distinguish one element from another and do not have sequentiality and importance.

[0051] Embodiment 1

[0052] A rotation planting method for tobacco, soybeans and corn aims to increase the yield of soybeans and obtain two crops of soybeans and corn at the same time.

[0053] Basically as attached Figure 1As shown, the planting method mainly includes the following steps:

[0054] S0: First, plant fertilizer - assisting plants in the land, and let the roots and stems of the fertilizer - assisting plants rot in the land, so as to increase the content of nutrients in the land, which is beneficial for the subsequent crops to grow more rapidly. In the embodiments of the present disclosure, the fertilizer - assisting plants planted can be Vicia villosa Roth var. glabrescens, Medicago sativa, Lolium perenne, etc. After the roots and stems of the fertilizer - assisting plants rot in the land, it helps to improve the soil fertility, enabling the subsequent crops to grow more rapidly.

[0055] S1, divide the land into a first planting ridge 1 and a second planting ridge 2 manually or by mechanical equipment, as can be referred to Figure 2 and Figure 3 . The first planting ridge 1 and the second planting ridge 2 are long - strip - shaped ridges. There are at least two of the first planting ridge 1 and the second planting ridge 2 respectively, and the specific quantity is determined according to the area of this piece of land. The widths of the first planting ridge 1 and the second planting ridge 2 can be the same. Of course, due to limitations such as the shape and area of the land, the widths of the first planting ridge 1 and the second planting ridge 2 may be different. In the embodiments of the present disclosure, it is preferred that the first planting ridge 1 and the second planting ridge 2 are arranged in parallel to each other.

[0056] Meanwhile, in the embodiments of the present disclosure, it is preferred that the first planting ridge 1 and the second planting ridge 2 are arranged at intervals in turn, that is: one first planting ridge 1, one second planting ridge 2, then another first planting ridge 1, then another second planting ridge 2, etc., arranged in sequence. By arranging the first planting ridge 1 and the second planting ridge 2 at intervals, when sowing autumn soybeans 5 in the first planting ridge 1 later, the shading on both sides of the autumn soybeans 5 will be less.

[0057] To be more beneficial to the growth of crops, different base fertilizers, such as tobacco - specific compound fertilizers and potassium sulfate, can be applied to the first planting ridge 1 and the second planting ridge 2 respectively.

[0058] S2, when the first planting ridge 1 and the second planting ridge 2 are formed, plant tobacco 3 in the first planting ridge 1 respectively and sow spring soybeans 4 in the second planting ridge 2 respectively, as Figure 2 shown. The planting of tobacco 3 and the sowing of spring soybeans 4 can both be completed by machinery. Of course, when there is a shortage of machinery or no machinery, the planting of tobacco 3 and the sowing of spring soybeans 4 can also be completed manually. In the embodiments of the present disclosure, there is no special requirement for the order of planting tobacco 3 and sowing spring soybeans 4, and the planting time of tobacco 3 and spring soybeans 4 is approximately the same.

[0059] In order to increase the yield of soybeans, during the growth process of soybeans in the second planting ridge 2, when the soybean seedlings grow to 15 - 20 cm, mid - tillage weeding and soil - banking are carried out; when the soybean seedlings enter the branching stage, 5 kg of urea and 7 kg of potassium nitrate are applied per mu to enhance the number of effective pod - setting branches. When the soybeans have two cotyledons, the upper undeveloped true leaves are removed to promote the growth of double main plants at the basal nodes of the stem. At the same time, before sowing soybeans, they are dressed with a biological bactericide. For example, the soybean seeds are dressed with a rhizobium agent so that the rhizobia are fully attached to the soybean seeds, and then the seeds are air - dried. After the seeds are air - dried, the soybean seeds are planted in the second planting ridge 2.

[0060] S3, when the spring soybeans 4 in the second planting ridge 2 are mature, the spring soybeans 4 are mechanically harvested, and the soybean stalks in the second planting ridge 2 are also mechanically uprooted. At this time, the harvested spring soybeans 4 are fully mature dry beans.

[0061] After the spring soybeans 4 are harvested, the spaces on both sides of the first planting ridge 1 are vacated. Therefore, the autumn soybeans 5 can be evenly sown in the first planting ridge 1 by a small seeder, and the autumn soybeans 5 are located on both sides of the tobacco 3, as Figure 3 shown. The autumn soybeans 5 can be sown in one row or multiple rows according to the remaining space according to the width of the first planting ridge 1.

[0062] It should be noted that: before sowing the seeds of the autumn soybeans 5, they are dressed with a biological bactericide, which is beneficial to increasing the yield of the autumn soybeans 5.

[0063] In order to prevent the lower leaves of the tobacco 3 from blocking the sunlight of the autumn soybeans 5, in the embodiments of the present disclosure, it is preferably to pick the lower leaves of the tobacco 3 before sowing the autumn soybeans 5. Therefore, when mechanically sowing the autumn soybeans 5, the machine will not damage the lower leaves of the tobacco 3. In the embodiments of the present disclosure, the picking of the lower leaves of the tobacco 3 can be completed before the spring soybeans 4 are harvested, or can be completed after the spring soybeans 4 are harvested and before sowing the autumn soybeans 5.

[0064] After the autumn soybeans 5 are sown into the first planting ridge 1, the corn 6 seedlings are transplanted into the second planting ridge 2, as Figure 3 shown.

[0065] In the embodiments of the present disclosure, it is preferably that the transplanted corn 6 is fresh - eating corn, and the fresh - eating corn can be eaten and used to make silage. The corn stalks of the fresh - eating corn can also be used as silage, with higher utilization rate.

[0066] In the embodiment of the present disclosure, the height of the corn 6 seedlings to be transplanted is already 10-15 cm, and the growth direction of their leaves has been determined. Therefore, according to the growth direction of the leaves, when transplanting, the leaf directions of the transplanted corn 6 seedlings can be made parallel to each other. Thus, mutual shading of the corn 6 from each other can be avoided. At the same time, the planting position of the autumn soybeans 5 in the first planting ridge 1 corresponds to the gap between two adjacent corn 6 seedlings in the second planting ridge 2, so as to minimize the shading of the autumn soybeans 5 by the corn 6 as much as possible.

[0067] In addition, when transplanting the corn 6 seedlings into the second planting ridge 2 in the embodiment of the present disclosure, the orientation direction of the leaves forms a 45-degree angle with the length direction of the second planting ridge 2. Thus, it is ensured that after the corn 6 grows taller, the shading effect on the autumn soybeans 5 is smaller.

[0068] It should be noted that: in the embodiment of the present disclosure, by transplanting the corn 6 seedlings, the growth time of the corn 6 in the second planting ridge 2 can be shortened, avoiding the situation that the corn 6 grows for too long and enters the cold season, and preventing the corn 6 from growing abnormally due to the climate. At the same time, the corn variety is fresh-eating corn, and the growth cycle of fresh-eating corn is shorter, which can also avoid the situation that the corn 6 grows for too long and enters the cold season, and prevent the corn 6 from growing abnormally due to the climate.

[0069] S4. After the tobacco 3 in the first planting ridge 1 matures, pick all the leaves of the tobacco 3 in the first planting ridge 1. At this time, tobacco stalks remain in the first planting ridge 1.

[0070] S5. Since the fresh-eating corn is planted in the embodiment of the present disclosure, when the fresh-eating corn can be harvested, immediately manually harvest the corn 6 in the second planting ridge 2 to prevent the fresh-eating corn from growing for too long and affecting the edible taste. After the fresh-eating corn is harvested, then mechanically remove the corn stalks and make the corn stalks into silage.

[0071] It should be noted that: if the consideration of harvesting fresh-eating corn for consumption is not taken into account, the fresh-eating corn and the corn stalks can be directly removed in the second planting ridge 2 by machine and made into silage uniformly.

[0072] S6. When the autumn soybeans 5 in the first planting ridge 1 grow to the green bean state, immediately manually pick the green beans to avoid the autumn soybeans 5 growing for too long and affecting the edible taste. After the autumn soybeans 5 are picked, then mechanically remove the tobacco stalks in the first planting ridge 1 and the autumn soybean stalks in the first planting ridge 1.

[0073] It can be understood that: when mechanically removing the tobacco stalks and autumn soybean stalks, the autumn soybeans 5 have been harvested, so the yield of the autumn soybeans 5 will not be affected.

[0074] Embodiment 2

[0075] The difference between the embodiment of the present disclosure and Embodiment 1 is that in S4 and S5 of the embodiment of the present disclosure, the corn 6 is ordinary corn. Therefore, the corn harvested in the second planting ridge 2 is ordinary corn, and the corn 6 and corn stalks in the second planting ridge 2 are not used as silage.

[0076] Embodiment 3

[0077] The difference between the embodiment of the present disclosure and Embodiment 1 is that in S6 of the embodiment of the present disclosure, the autumn soybeans 5 harvested in the first planting ridge 1 are ordinary dry beans. Therefore, in S6 of the embodiment of the present disclosure, first, the tobacco stalks are mechanically removed, and then after the autumn soybeans 5 grow into dry beans, the autumn soybeans 5 are harvested in sequence and the autumn soybean stalks are removed.

[0078] It should be noted that: Since in S3, the autumn soybeans 5 are mechanically and evenly sown on both sides of the tobacco 3, when the tobacco stalks are mechanically removed, the mechanical device has little impact on the autumn soybeans 5 on both sides, and the yield of the autumn soybeans 5 will not be affected by the mechanical stalk removal.

[0079] Embodiment 4:

[0080] The difference between the embodiment of the present disclosure and Embodiment 1 is that as Figure 4 、 Figure 5 and Figure 6 shown, the embodiment of the present disclosure provides a new planting method that can simultaneously achieve the rotation of tobacco leaves, soybeans, corn 6 and buckwheat 9, so as to obtain four crops: tobacco leaves, soybeans, corn 6 and buckwheat 9.

[0081] The planting method of the embodiment of the present disclosure mainly includes the following steps:

[0082] S0: First, fertilizer-assisted plants are planted in the land, and the roots and stems and leaves of the fertilizer-assisted plants are allowed to rot in the land, so that the nutrient content in the land is increased, which is beneficial to the subsequent crops growing more rapidly. The fertilizer-assisted plants planted in the embodiment of the present disclosure can be Vicia villosa Roth, Medicago sativa L. and Lolium perenne L., etc. After the roots and stems and leaves of the fertilizer-assisted plants rot in the land, it helps to improve the soil fertility, enabling the subsequent crops to grow more rapidly.

[0083] S1: Manually or through mechanical equipment, the land is divided into a first planting ridge 1, a second planting ridge 2, a third planting ridge 7 and a fourth planting ridge 8. As Figure 5 and Figure 6 shown, the first planting ridge 1, the second planting ridge 2, the third planting ridge 7 and the fourth planting ridge 8 are all in a long strip shape, the first planting ridge 1, the second planting ridge 2, the third planting ridge 7 and the fourth planting ridge 8 are arranged in parallel in sequence, and at least two of the first planting ridge 1, the second planting ridge 2, the third planting ridge 7 and the fourth planting ridge 8 are respectively provided.

[0084] S2: Plant tobacco 3 in the first planting ridge 1 and the third planting ridge 7, and plant spring soybeans 4 in the second planting ridge 2 and the fourth planting ridge 8. As Figure 5 shown. The tobacco leaves and spring soybeans 4 can be planted manually or mechanically, and there is no special requirement for the order of planting tobacco 3 and sowing spring soybeans 4. The planting time of tobacco 3 and spring soybeans 4 is roughly the same.

[0085] S3: After the spring soybeans 4 are mature, harvest the spring soybeans 4 in the second planting ridge 2 and the fourth planting ridge 8. The spring soybeans 4 are harvested by machine, reducing the workload of the planters. When the spring soybeans 4 are harvested, the spaces on both sides of the first planting ridge 1 and the third planting ridge 7 are vacated. Therefore, autumn soybeans 5 or buckwheat 9 can be evenly sown in the first planting ridge 1 and the third planting ridge 7 by a small seeder, and the autumn soybeans 5 or buckwheat 9 are respectively located on both sides of the tobacco 3. The autumn soybeans 5 and buckwheat 9 can be sown in one row or multiple rows according to the width of the first planting ridge 1 and the remaining space.

[0086] To avoid the lower leaves of the tobacco 3 blocking the sunlight of the autumn soybeans 5 and buckwheat 9, in the embodiments of the present disclosure, it is preferably to pick the lower leaves of the tobacco 3 first before sowing the autumn soybeans 5 and buckwheat 9. Therefore, when sowing the autumn soybeans 5 and buckwheat 9 by machine, the machine will not damage the lower leaves of the tobacco 3. In the embodiments of the present disclosure, the picking of the lower leaves of the tobacco 3 can be completed before the spring soybeans 4 are harvested.

[0087] After the autumn soybeans 5 and buckwheat 9 are sown into the first planting ridge 1 and the third planting ridge 7, then plant the corn 6 seedlings and buckwheat 9 seeds in the second planting ridge 2 and the fourth planting ridge 8 respectively. As Figure 6 shown. It should be noted that: there is a third planting ridge 7 between the second planting ridge 2 and the fourth planting ridge 8, so the corn 6 and buckwheat 9 will not be blocked from sunlight, and at the same time, the normal growth of the corn 6 and buckwheat 9 is ensured. At the same time, the corn 6 is also transplanted to avoid the corn 6 growing in the second planting ridge 2 for too long.

[0088] S4: When the tobacco leaves are mature, pick all the leaves of the tobacco 3 in the first planting ridge 1 and the third planting ridge 7. At this time, there are tobacco 3 stalks remaining in the first planting ridge 1 and the third planting ridge 7.

[0089] S5: When the corn 6 and buckwheat 9 are mature, harvest the corn 6 in the second planting ridge 2 and the buckwheat 9 in the fourth planting ridge 8 respectively. The corn 6 and buckwheat 9 are respectively located in different planting ridges, so the harvest of the corn 6 and the harvest of the buckwheat 9 will not affect each other.

[0090] S6: After the autumn soybeans 5 or buckwheat 9 in the first planting ridge 1 and the third planting ridge 7 are mature, harvest the autumn soybeans 5 or buckwheat 9 in the first planting ridge 1 and the third planting ridge 7. After the autumn soybeans 5 or buckwheat 9 are picked, then mechanically remove the tobacco stalks 3 in the first planting ridge 1 and the third planting ridge 7.

[0091] Example 5

[0092] In the embodiments of the present disclosure, improvements are made on the basis of Embodiment 1. As Figure 7 and Figure 8 shown, in order to further solve the problem that the tobacco 3 shades the autumn soybeans 5 planted on both sides of the tobacco 3 and the problem that the tobacco 3 shades the seedlings of autumn corn 6, in step S3 of the embodiments of the present disclosure, a reflective member 10 is further arranged between adjacent planting ridges, and the sunlight between adjacent planting ridges is reflected by the reflective member 10, so as to improve the sunlight irradiation of the autumn soybeans 5 and the autumn corn 6.

[0093] The reflective member 10 in the embodiments of the present disclosure includes arc-shaped reflective plates 101 arranged symmetrically, and the arc-shaped reflective plates 101 are connected by a support plate 102. The arc-shaped reflective plates 101 are arc-shaped, and a reflective film is arranged on the surface of the arc-shaped reflective plates 101. When sunlight irradiates on the reflective film, the reflective film will diffusely reflect the sunlight, so that the crops in the shaded area can receive light. In the embodiments of the present disclosure, the arc-shaped surfaces of the arc-shaped reflective plates 101 face the adjacent ridge fields, so that the sunlight irradiated on the arc-shaped reflective plates 101 can be reflected to the bottom of the adjacent ridge fields.

[0094] Taking an application scenario as an example: When the sun shines into the first planting ridge 1 at a 45° angle, the autumn soybeans 5 on the backlight side in the first planting are blocked by the tobacco 3 and the sunlight cannot shine. At this time, the sunlight will shine on the arc-shaped reflective plate 101 beside the first planting ridge 1, and the arc-shaped reflective plate 101 reflects the sunlight, so that the sunlight is reflected onto the autumn soybeans 5 on the backlight side of the first planting ridge 1, and the autumn soybeans 5 in the shaded area receive light, thereby increasing the yield of the autumn soybeans 5.

[0095] Both ends of the support plate 102 are connected to the arc-shaped reflective plates 101 by configuring fasteners or by fitting or other means. The support plate 102 can limit the two side arc-shaped reflective plates 101, so that the arc-shaped reflective plates 101 will not move.

[0096] Taking an application scenario as an example: When the rainy season comes, the rainwater will impact the ridge fields, causing the newly planted autumn soybeans 5 and autumn corn in the ridge fields to be washed out of the ridge fields or their planting positions to shift. Therefore, the arc-shaped reflective plates 101 on both sides in the reflective member 10 will respectively play the role of limiting the edge of the ridge field, preventing the ridge field from being washed out, and preventing crops such as autumn soybeans 5 from being washed away or changing their planting positions.

[0097] It should be noted that, in order to prevent a large amount of rainwater from being blocked by the arc-shaped reflector 101 and accumulating in the ridges, a number of drain holes are evenly arranged on the arc-shaped reflector. Through the drain holes, the rainwater can flow out of the ridges, avoiding excessive rainwater in the ridges.

[0098] Embodiment 6

[0099] The embodiment of the present disclosure makes further improvements on the basis of Embodiment 5. For example, Figure 9 As shown, in the embodiment of the present disclosure, considering that due to the different positions of the land, some lands have a certain inclination angle. Based on this, the arc-shaped reflector 101 in the embodiment of the present disclosure is arranged to be rotatably installed. Therefore, according to the different positions of the land, the angle of the arc-shaped reflector 101 can be rotated so that the arc-shaped reflector 101 can accurately reflect sunlight to the position that needs illumination.

[0100] During implementation, installation holes can be provided at the bottom end of the arc-shaped reflector 101, and at the same time, mating holes are also constructed at the end of the support plate 102, and then bolts are passed through the installation holes and the mating holes. When the bolts are loosened, the arc-shaped reflector 101 and the support plate 102 can rotate around the bolts, causing the angle of the arc-shaped reflector 101 to change. When the bolts are tightened, the bolts fixedly install the arc-shaped reflector 101 and the support plate 102 together, and the arc-shaped reflector 101 can no longer rotate, and the arc-shaped reflector 101 can be maintained at a predetermined angular position.

[0101] At the same time, when the spring soybeans 4 in the second planting ridge are mature, the arc-shaped reflector 101 can be rotated so that the arc-shaped reflector 101 extends below the spring soybeans 4. Therefore, the mature spring soybeans can directly fall into the reflector member 10 for collection, which is more convenient and also avoids the spring soybeans 4 falling on the land and causing a decrease in yield.

[0102] It should be noted that: in order to prevent the spring soybeans 4 from leaking out through the drain holes, in the embodiment of the present disclosure, it is preferred that the aperture of the drain hole is smaller than the diameter of the soybeans.

[0103] Embodiment 7

[0104] The embodiment of the present disclosure makes improvements on the basis of Embodiment 1. In order to be able to plant more tobacco 3, autumn soybeans 5 and corn in the land, and it is necessary to try to ensure that the autumn soybeans 5 are not shaded by the tobacco 3 as much as possible. Therefore, the embodiment of the present disclosure provides a calculation method for calculating the reasonable number of the first planting ridge 1 and the second planting ridge 2 in the land.

[0105] It should be noted that: for this calculation method, the first planting ridge 1 and the second planting ridge 2 need to be set in the north-south direction so that the sun shines into the first planting ridge 1 and the second planting ridge 2 in the east-west direction. At the same time, it is preferably ensured that when the sun shines at an angle of 40°, the sunlight can shine on the autumn soybeans 5 to ensure sufficient sunlight for the autumn soybeans 5.

[0106] In the embodiment of the present disclosure, the length of the land is set to S (unit: meter), the number of the first planting ridges 1 in the land is set to X1, and the number of the second planting ridges 2 in the land is set to X2.

[0107] Therefore, the number of the first planting ridges 1 in the land , the number of the second planting ridges 2 in the land .

[0108] It should be noted that: 1.5 meters is the approximate height of the tobacco 3 when the soybeans are planted on the side of the tobacco 3. (1.5 / tan40°) is the minimum distance between the tobacco 3 in the first planting ridge 1 and the tobacco 3 in the second planting ridge 2 when the shading is not hindered. If the numbers obtained for X1 and X2 are not integers, only the integers are taken, and the extra decimals are the remainders between the planting ridges, which is convenient for personnel operation.

[0109] Taking an application scenario as an example: Suppose there is a 50-meter-long land that needs to be planned for the first planting ridge 1 and the second planting ridge 2, and it is necessary to ensure that the autumn soybeans 5 are not shaded as much as possible. That is: S = 50. Therefore, the number of the first planting ridges 1 in the land, X1≈28.9798, and after rounding, X1 = 28. The number of the second planting ridges 2 in the land, X2≈27.9798, and after rounding, X2 = 27. The decimals discarded in X1 and X2 are the remainders between the planting ridges.

[0110] The above are only the embodiments of the present invention. Common general knowledge such as the specific structures and characteristics in the solutions is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several deformations and improvements can still be made, and these should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicability of the patent. The protection scope required by this application should be based on the content of its claims, and the specific implementation manners and the like recorded in the description can be used to explain the content of the claims.
