A kind of forage grass and its processing method

Abstract

The invention relates to the technical field of agriculture and discloses herbage and a processing method thereof. The processing method disclosed by the invention comprises the steps of cutting herbage in booting stage into sections, uniformly mixing straws which are cut into sections with the herbage according to the mass ratio of (6:4)-(9:1), and performing closed normal-temperature fermentation for 1-2 months. The conventional single mode for ensiling fermented herbage is changed; the straws obtained by harvesting soybeans and rice are mixed with the herbage for realizing ensiling fermentation, and the proper mixing proportion is defined, so that the content of dry substances in the processed herbage is increased, the loss rate of crude proteins and soluble carbohydrates is reduced, the degrading rate of acidic washing fibers and neutral washing fibers is increased, the content of propionic acid, acetic acid and butyric acid is reduced, and the ratio of ammoniacal nitrogen to total nitrogen is obviously reduced; the processing method is suitable for popularization and application in the herbage industry.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a forage grass and a processing method thereof. Background technique [0002] Animal husbandry is the leading industry of agricultural economy in Southwest my country, and plays an irreplaceable role in its social economy. Grass is an indispensable part of animal husbandry. In the past ten years, my country's animal husbandry has developed very rapidly. There are more and more large-scale farms, and the degree of intensification is getting higher and higher. However, in terms of raw material supply, supply The amount is far from meeting the needs of the development of animal husbandry. The more serious situation is that in the high-humidity areas in southern my country, many forages cannot be made into hay for storage due to weather conditions, which directly leads to a decline in forage production and makes the already insufficient forage production worse.

AI Technical Summary

Problems solved by technology

At the same time, the fermentation quality of forage grass after direct silage is poor, which is one of the reasons for the failure of forage storage in high-humidity areas.

A variety of objective factors limit the fermentation quality of forage silage, which greatly limits the long-term development of my country's animal husbandry. It is necessary to provide a new agricultural technology to solve the above problems
