Problems solved by technology

[0003] Corn straw is the main feed for ruminants, but the harvested corn yellow straw has low nutrition, hard texture, high crude fiber content, poor palatability and low utilization rate
At present, the research mainly focuses on lactic acid bacteria to improve the palatability of forage grass, which is relatively low in improving the utilization rate and nutritional value of straw.
At the same time, the contact surface is small in the form of powdered block straw, which cannot effectively improve its nutritional value.
[0004] In the current field of feed, there are still the following defects: 1. Not every farm has a cellar, and the fermentation is not easy to control; 2. If part of the fermentation is infected with bacteria, it will be broken, and once it breaks, it will all be broken; 3. Enzymatic hydrolysis The inoculation is not uniform at the time, and it is not easy to carry out uniform enzymatic hydrolysis in all directions; 4. It is not easy to commercialize production; 5. It is not easy to pack; 6. It is not easy to weigh

Abstract

The invention relates to the field of biological agriculture, in particular to a method for preparing forage grass from a complex leavening agent and biological yellow corn silage of yellow corn straw. The forage grass is prepared from, by weight, 20-30 parts of cellulase, 15-20 parts of ligninase, 8-12 parts of protease, 5-8 parts of lipase, 5-8 parts of pectinase, 5-8 parts of a trichoderma viride solution, 8-12 parts of a lactic acid bacterium solution, 8-12 parts of a saccharomycetes solution and 8-10 parts of urea. The method has the advantages that the operation is simple and convenient,the straw degradation utilization rate is high, the cost is low, and the environment is not polluted; the prepared forage grass has high content of protein saccharides, can increase the nutritive value, and can increase the digestive absorption utilization rate of the forage while improving the palatability.

Description

technical field [0001] The invention relates to the field of biological agriculture, in particular to a compound starter and a method for preparing forage grass from corn yellow stalk biological silage. Background technique [0002] Corn as the main crop in northern my country occupies a large proportion of planting, but most of the corn stalks are randomly piled up or incinerated after harvesting. After the corn stalks are burned, a large amount of solid particles can be released into the air, which not only causes air pollution but also Harm to people's health. At the same time, as a large agricultural country, my country has too many people and too little land, which seriously degrades the grassland, and the shortage of forage becomes increasingly prominent, which restricts the development of animal husbandry. my country is rich in corn stalk resources, so it is of great significance to develop the resource utilization of corn yellow stalks to solve the shortage of forage...
