Background
In recent years, the rainfall in the multicast season in the downstream region of the Yangtze river is too large, and the rainfall duration in the sowing season in certain regions is too long. According to research, the total rainfall in the middle and downstream regions of the Yangtze river is increasing year by year. Objectively, the number of wet and rotten land blocks in the sowing season is increased. The existing machine tools can not sow in the ground in the wet rotten land, and can not operate in the ground until the soil is dried in the sun to a certain extent, so that the later sowing and the later planting are caused. The large amount of late seeding, late planting means planting rushed planting, while the rushed planting form is currently mainly used for increasing the operation speed of the machine, and the speed of seeding is accelerated, which inevitably leads to the degradation of seeding quality. Meanwhile, the sowing time is delayed from the proper sowing period, so that the germination and emergence of seeds are greatly influenced, and the yield is further influenced. Therefore, the competing sowing time is significant to farmers. In order to ensure that farmers can normally sow in wet rotten land to fight against sowing time, the harm of late sowing is reduced, and thus the benefits of the farmers are ensured. In combination with the current popularization of clean-area sowing technology, the yield is improved, and the research on a sowing machine capable of sowing in the clean area on wet and rotten land is urgently needed.
