Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an efficient and environment-friendly corn stubble crushing and returning device. Background technique [0002] Corn stubble is the remaining stubble after cutting off the stalk. It is one of the main by-products in food production, and it is also an important resource for industrial and agricultural production. It is an extremely rich and directly usable renewable resource. Corn stubble Containing the main nutrient elements necessary for crop production, it is one of the important organic fertilizers in my country. As the organic content of farmland soil is decreasing year by year, the technology of crushing and returning corn stubble to the field has become an agricultural development direction. However, most of them are now when sowing, the corn stubble is turned up together with the soil with a cultivator, sown and covered with the soil mixed with the whole cor...
