Straw decomposing agent and preparation method thereof

Abstract

The invention discloses a straw decomposing agent and a preparation method thereof. The preparation method comprises the following steps: culturing bacillus subtilis, bacillus licheniformis, liquor-making yeasts, aspergillus niger and trichoderma koningii respectively until the bacterial concentration is (0.1-1)*10<8> / mL, uniformly mixing according to a bacterial amount ratio, inoculating to sugarcane leaves according to a ratio of 1 to (10-20) for culturing at 25-30 DEG C for 5-10 days under the condition that the moisture content of the sugarcane leaves is 30%-50%, and finally grinding the sugarcane leaves to be 20-100-mesh to prepare the straw decomposing agent. According to the preparation method, the bacterial selection and ratio are reasonable, and the bacteria have a synergistic effect, can effectively decompose ingredients such as cellulose, hemicelluloses and lignin in straws and increase the decomposing speed, and can effectively decompose the straws within 15 days in general; the preparation method is simple and easy to control, the culture is mainly carried out at the room temperature, a high-price culture agent does not need to be added, the production cost can be reduced, and the promotion is facilitated.

Description

technical field [0001] The invention relates to a straw decomposing agent and a preparation method thereof. Background technique [0002] Straw refers to the remaining stems and leaves of gramineous crops such as rice, wheat, and corn after threshing; among them, rice straw is often called straw, rice straw, commonly known as straw grass; wheat straw is called wheat straw. Due to the popularization of coal, electricity and natural gas and the abundance of various industrial products in China in the past two decades, the demand for straw in rural areas has decreased, and the disposal of a large amount of straw has become a serious social problem. Although it is prohibited by law, farmers in many places still directly Burning straw in the fields has caused air pollution, fires, and the failure of planes to take off and land normally. With the development of agricultural production, the utilization of straw has changed from the original composting manure to direct return of st...

Problems solved by technology

However, common straw decomposing agents are expensive, take a long time to decompose, and the decomposing effect is not obvious, so farmers seldom use them
