Ensilage method of ear-removed corn straw

Abstract

The invention discloses an ensilage method of ear-removed corn straw. The ensilage method comprises the following steps: 1, harvest of straw; 2, cutting short of straw; 3, addition of lactic acid bacteria powder and molasses; 4, loading and compacting; 5, sealing and storing; and 6, use of silage. By addition of the molasses and the lactic acid bacteria in the ensilage processing course of the corn straw, the lactic acid bacteria are promoted to rapidly ferment to reduce the pH value of the silage, the activities of harmful microbes and plant clastic enzymes are inhibited, loss of nutrient substances in the ensilage fermentation process is reduced, the feed utilization ratio of the straw is improved, the fermentation quality of silage is improved and loss of the nutrient substances in theensilage fermentation process is reduced.

Description

technical field [0001] The invention relates to a utilization method of earless corn stalks, in particular to a silage method of earless corn stalks, which belongs to the technical field of feed processing. Background technique [0002] my country is extremely rich in cellulose resources, with an annual straw output of 570 million tons, accounting for 20% to 30% of the world's total straw output. Rice straw, wheat straw and corn straw are the three major crop straws in my country and the main straw in all countries in the world. However, as a non-competitive resource, crop straw is used as feed for less than 10% in my country. If these resources can be fully and effectively utilized, it will become one of the important ways to alleviate the three major crises of "food, energy and environment" that mankind is facing today, and to achieve sustainable agricultural development. However, due to the high crude fiber content of straw feed, low protein and available mineral content...

Problems solved by technology

However, as a non-competitive resource, crop straw is used as feed for less than 10% in my country.

[0007] There are more than 30 million tons of crop straw in Guizhou every year, but the utilization rate of straw is less than 15%. A large amount of corn straw is directly used for fuel incineration or discarded in the corner of the field to rot and mold

The content of water-soluble carbohydrates and crude protein in corn stalks without ears is low, and the number of lactic acid bacteria attached to them is limited, so the quality of natural silage fermentation of corn stalks is low
