Straw crushed and returned to the field can slowly decompose and release mineral nutrients in the soil through the action of microorganisms in the soil and be absorbed and utilized by crops. Organic matter and humus formed in the decomposition process can provide raw materials for microorganisms and soil organisms in the soil, thus effectively improving soil structure and soil fertility. As livestock feed, corn stalk is one of the most effective utilization ways of straw and can bring certain economic benefits. Corn stalk, as a by-product of feed, is a good raw material for farmland. Making biogas directly from straw resources can effectively alleviate the problem of rural energy shortage. After corn stalk is crushed, a certain proportion of phosphate fertilizer, ammonia fertilizer, lime and water are added for fermentation. The fermented clinker can be bagged to produce edible fungi, such as Coprinus comatus and mushrooms, and the biotransformation rate can reach 70% ~ 100%, and the waste can be used as farm manure. The new corn straw beverage has bright color, unique aroma of straw, sweet and sour taste, excellent taste and uniform texture.
