Description

technical field [0001] The invention relates to an integrated machine for ditching, topdressing, suppressing and covering soil in a wheat field. Background technique [0002] Many studies have shown that reducing the proportion of nitrogen base fertilizer to 50% and increasing the proportion of topdressing fertilizer to 50% in wheat fields can not only increase yield, improve quality, improve economic benefits, but also reduce environmental risks. Research also shows that deep application of nitrogen fertilizer can enhance the adsorption of ammonium nitrogen in soil, reduce ammonia volatilization, loss with water and denitrification denitrification loss. Under the condition of deep nitrogen application of 10-15 cm, the loss rate of ammonia volatilization can be easily reduced To less than 10%, can significantly improve nitrogen use efficiency and wheat yield. In the 1980s and 1990s, wheat farmers in the Huanghuai wheat region used animal power to pull wheat seeders to carry...

Problems solved by technology

In the 1980s and 1990s, wheat farmers in the Huanghuai wheat region used animal power to pull wheat seeders to carry out topdressing operations. However, with the reduction of animal power and the replacement of wheat seeders, this method of topdressing has no longer been used in production. Existence, replaced by "top-dressing" topdressing method, resulting in ammonia volatilization loss of up to 50%

In 2007, Lou Zhanchun developed "a kind of wheat topdressing device". This machine requires supporting power, and the production cost is relatively high. There is still a certain distance from the purchasing power of farmers with scattered land management, and the operating cost of this machine is relatively high. It is not complementary to the economic benefits of output; with the continuous deepening and maturity of wheat topdressing agronomic technology research, nitrogen fertilizer deep topdressing has become an important agronomic technology for high wheat yield

However, in the process of topdressing many types of wheat topdressing machines developed in the past, when the soil moisture is relatively large or normal, in heavy sticky, medium sticky, light sticky and heavy loam soils, different sizes often appear after ditching. First, the soil is rubbish, resulting in a poor condition of "soil return (soil return joint)". After topdressing, the fertilizer is exposed at the bottom of the topdressing ditch, and the fertilizer often cannot be covered with soil.

This situation often leads to: first, the effect of covering the soil with nitrogen fertilizer is poor, which easily causes the volatilization of ammonia; second, the wind in spring loses moisture quickly, and these problems often result in low nitrogen fertilizer use efficiency and poor moisture conservation effect
