Abstract

The invention relates to the technical field of silage, and provides a method for increasing the protein content of silage corn feed. The method which comprises the following steps that silage corn is planted on two sides of a planting belt, and soybeans are planted in the planting belt; 2-3 days after the soybeans and the corn are sown, herbicide is correspondingly sprayed in the period of 2-3 compound leaves of the soybeans and the period of 3-5 leaves of the corn; topdressing is correspondingly carried out in a corn seedling stage, a corn jointing-booting stage and a tasseling-flowering stage; and harvesting and ensiling are carried out from the late milk-ripening stage to the early dough-ripening stage of the corn kernels and the late plump-grain stage of the soybeans. According to the method for increasing the protein content of the silage corn feed, silage corn and soybeans are compositely planted, so that the edge row advantage of high-stalk crop corn is exerted, the utilization rate of land, water, nutrients, space and light and heat resources is increased, nitrogen fixation of soybean root nodules increases soil nitrogen, diversity of soil bacterial communities is enriched, soil quality is improved, the effect of crop rotation is achieved, a planting and breeding combined circular agriculture mode is realized, and the ecological benefit is remarkable.

Description

technical field [0001] The invention relates to the technical field of silage feed, in particular to a method for increasing the protein content of silage corn feed. Background technique [0002] The current main sources of silage are crop straw, annual forage grass and perennial forage grass. Among them, the output of crop straw silage is more than 190 million tons, the output of annual forage grass silage is more than 60 million tons, and the output of perennial forage grass silage is more than 30 million tons, of which corn silage accounts for the largest proportion. Silage corn feed, which uses silage corn as the main raw material, needs additional soybean meal to supplement the protein content in the feed, which poses a challenge to the national soybean supply. [0003] With the rapid development of animal husbandry, the supply of high-quality forage is seriously insufficient. Silage corn and high-protein soybeans are planted together, and the whole plant corn and soy...
