Description

Technical Field

[0001] The present invention relates to the field of agricultural machinery, and particularly to an integrated drill suitable for waterlogging-resistant cultivation of soybeans. Background Art

[0002] Modern soybean production presents the characteristics of "high-density planting, large-scale, mechanization, and standardization". The soybean seeder needs to complete ridging, ditch opening, sowing, and fertilizing at one time, and try to achieve a light, simple, and efficient operation efficiency, and reduce the disturbance to the field and the damage to the soil. The growing period of soybeans in the main producing areas of our country is the season with more rain, and waterlogging disasters occur frequently. Therefore, the drainage setting of field ditches should be scientific and reasonable, and sowing on ridges and draining in furrows are important guarantees for waterlogging-resistant cultivation. In addition, reasonable close planting is the key technology for high-yield soybeans. There are various soybean varieties in our country, and the suitable densities of different varieties vary greatly. If the row spacing or plant spacing is too small, it will affect ventilation and is not conducive to the growth of pods; if the row spacing or plant spacing is too large, it will cause the soybean seedlings to grow wildly, with few or no pods, and lead to insufficient grain filling and reduced grain weight. Therefore, the soybean seeder needs to be able to adjust the row spacing and plant spacing at any time.

[0003] At present, the existing soybean seeders in our country can effectively improve work efficiency and save labor. However, there is a drawback in the existing sowing equipment that it does not consider the problem of integrating soybean sowing and crop management; it also does not reasonably consider the problem of field waterlogging drainage; at the same time, there is a problem that during the soil covering process, the ground is easily pressed too hard, affecting the emergence rate.

[0004] In order to solve the above technical problems, there is an urgent need for a row-spacing and plant-spacing adjustable precision seeder that can integrate ridging, fertilizing, ditch opening, sowing, compaction, and watering to achieve high-yield and high-efficiency waterlogging-resistant cultivation of soybeans.
