Abstract

The invention provides a biological preparation for treating crop straw. The biological preparation is prepared from complex microbial agents and auxiliaries according to a proportion of 1-2:3-5. Fermentation cytophaga, alcaligenes faecalis, paracoccus denitrificans, bacillus pumilus, phanerochaete chrysosporium and actinomycetes are mixed with one another according to a volume ratio of 5:4:2:6:1:3 to obtain the complex microbial agents. The biological preparation has the advantages that the problems of tight crop rotation between two seasons of crops due to the fact that all straw returns to fields locally, difficulty in carrying out cuttage and seed sowing on next-stubble crops, yellowing and seedling weakness due to nitrogen fighting between seedlings and straw decomposition and the like can be effectively solved by the aid of the biological preparation; the straw can return to fields locally, and the biological preparation can be widely applied to returning the crop straw of rice, wheat, corn and the like to the fields.

Description

technical field

[0001] The invention belongs to the technical field of soil improvement, and relates to a biological agent for treating crop straws. The bacterial agent is suitable for returning the crop straws to the field when they are decomposed. Background technique

[0002] Chinese farmers have a long history of using crop stalks, but due to the low level of agricultural production and low output in the past, the amount of stalks was small. Except for a small amount of straw used for gaskets, feeding livestock, and some used for composting, most of the straw was used as fuel. Lost. With the development of agricultural production, since the 1980s, China's grain output has increased significantly, and the amount of straw has also increased. In addition, the promotion of firewood-saving and coal-saving technologies, the popularization of coal burning and the use of liquefied petroleum gas have resulted in a large amount of surplus straw in rural areas. . At the same time...
