Description

Technical Field

[0002] In the process of modern agricultural production, wheat is one of my country's important grain crops. The optimization and improvement of its sowing method is of great significance to improving planting efficiency and ensuring crop quality. With the improvement of agricultural mechanization, wheat seeders, as an efficient agricultural machinery, have gradually occupied an important position in agricultural production.

[0003] As in the patent with prior art authorization announcement number CN201623982U, the purpose of this utility model is to provide a variable deep fertilization precision seeder that controls the amount of fertilizer according to local conditions and integrates variable deep fertilization and precision sowing. The utility model adopts a parallel four-bar profiling mechanism, a spoon-type precision seeding device and a narrow-core plowshare type furrow opener, which realizes accurate sowing amount, single-body profiling and single-body driven seeding, improves soil penetration performance, reduces the slippage of the seeder, and ensures accurate sowing amount and plant spacing.

[0004] However, during the use of the seeder, it was found that the seeder was not convenient for achieving the effect of controlling and adjusting different plant spacings when sowing multiple rows simultaneously according to the sowing plant spacing requirements, which reduced the limitations of the sowing plant spacing adjustment. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention provides a wheat sowing method and a variable seeding seeder that improve the optimization effect of the wheat growth environment, increase wheat planting yield, and improve the convenience of planting multiple rows of wheat at different plant spacings at the same time.

[0006] A wheat sowing method of the present invention comprises the following steps:

[0007] S1. By controlling the sowing spacing of the sowing equipment, the spacing between the four rows of wheat is maintained at 10 cm to 13.3 cm, and the four rows of wheat are sown on a 30 cm to 40 cm wide field;

[0008] S2. During the simultaneous sowing of four rows of wheat in S1, the spacing between the seeding legs of the sowing equipment is controlled so that the spacing between the two outermost rows of wheat is maintained at 10-13.3 cm, and the spacing between the two middle rows of wheat is maintained at 20-30 cm, thereby forming a sowing pattern with different row spacings for the wheat;

[0009] S3. After the four rows of wheat are sown simultaneously in S2, leave 20 cm to 30 cm of open space on the sides of the four rows of wheat, and then sow four more rows of wheat in the same manner as in S2 until the field is fully planted.

[0010] S4. Based on S3, the spacing between the outer and inner rows of wheat in the four rows of wheat is adjusted by regulating the seed meter, so that the sowing amount of the two outer rows is increased by 20-25%, and the sowing amount of the two inner rows is reduced by 20-25%, so that wheat forms a sowing pattern with different row spacings and dense outer and sparse inner.

[0011] S5. After wheat is harvested, corn is sown in the 20-30 cm space left beside every four rows of wheat.

[0012] S6. Lay drip irrigation tape between the 10cm-13.3cm gaps in the middle of every four rows of wheat;

[0013] By adopting the sowing method of dense outside and sparse inside with different plant spacing for wheat sowing, the existing situation of the same sowing amount for each row of wheat is optimized, which causes the two middle rows of the four rows to be too crowded and the advantages of the wheat side rows on the left and right outer rows cannot be fully utilized.

[0060] like Figures 1 to 12 As shown, a wheat sowing method and a variable seeding seeder of the present invention are provided. When the wheat seeds are in operation, the wheat seeds are placed in the seed box 102. The wheat seeds in the seed box 102 flow downward through the multiple groups of first funnels 103 under the force of gravity and are discharged into the multiple groups of conveying cylinders 104. The seeds entering the conveying cylinders 104 fall into the feeding trough 108 at the top. When the frame 101 moves forward, the driving device drives the support shaft 106 to rotate, so that the support shaft 106 drives the multiple groups of discs 107 to rotate, thereby causing the multiple groups of feeding troughs 108 to move circumferentially to convey the seeds downward. The seeds are discharged downward through the discharge pipe 105 and fall into the plowed furrow, thereby realizing automatic sowing of wheat. When it is necessary to adjust the plant spacing of multiple rows of wheat planted at the same time, the adjustment device drives the disc 107 to move left or right for adjustment, so that the feed troughs 108 with different spacings are switched and moved to the bottom end of the first funnel 103. When the support shaft 106 drives the multiple groups of discs 107 to rotate, the feed troughs 108 with different spacings achieve the effect of sowing wheat with different plant spacings in the front and back. By moving the furrowing device left and right for adjustment, the left and right plant spacing of multiple rows of wheat can be adjusted.

[0061] The main functions achieved by the present invention are: by sowing wheat in a sowing method with different plant spacings of dense outside and sparse inside, the existing situation in which the sowing amount of wheat in each row is the same, resulting in the two middle rows of four rows being too crowded and the wheat side row advantages of the two outer rows on the left and right cannot be fully utilized; the sowing effect of different plant spacings in front and behind wheat and the adjustment of the plant spacing on the left and right are achieved, the convenience of planting wheat in multiple rows at the same time with different plant spacings is improved, the wheat sowing method is optimized, and the wheat yield is increased.

[0062] The first hydraulic cylinder 203, the transmission 303 and the second hydraulic cylinder 603 of the wheat sowing method and the variable seeding seeder of the present invention are purchased on the market. Technicians in this industry only need to install and operate them according to the accompanying instruction manual without the need for creative work by technicians in this field.

[0063] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
