Description

technical field [0001] The invention relates to an agricultural machinery used for water and soil conservation, in particular to a crushed straw deep application machine. Background technique [0002] In modern agricultural production, crushed crop stalks are often applied to the soil at a certain depth in the cultivated land as required. In this way, the infiltration speed and water storage capacity of the soil can be improved by increasing the voids in the soil, that is, in the soil This is one of the effective measures to solve the lack of soil moisture in arable and semi-arid areas. The technology of burying straw in the soil can not only prevent soil erosion caused by surface runoff, but also effectively improve the utilization rate of precipitation, increase the water supply of soil to crops, and increase grain production. [0003] However, at present, deep application of straw is generally made by manually laying straw into furrows opened by the common plow and then ...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a crushed straw deep application machine to solve the technical problems in the above background technology, that is, when the straw is manually applied to the soil of a certain depth in the cultivated land, the operation efficiency is low, the labor intensity is high, and the operation is relatively difficult.
