Abstract

The invention belongs to the field of comprehensive utilization of crop straws and relates to a compound bacterial agent applied to high-efficiency quick straw decomposition. The compound bacterial agent applied to the high-efficiency quick straw decomposition is composed of a dewaxing bacterial agent and an enamelysin bacterial agent, wherein the dewaxing bacterial agent is a compound bacterial agent of Bacilluscereus, Bacillussubtilis and Clostridiumpasteurianum, and the enamelysin bacterial agent is a compound bacterial agent of P.chrysosporium, Aspergilusoryzae and Trichodermaviride. The compound bacterial agent applied to the high-efficiency quick straw decomposition can realize high-efficiency quick straw decomposition, straws are converted into an environmental-friendly organic fertilizer, and cyclic regeneration of biological energy sources is realized.

Description

technical field [0001] The invention belongs to the field of comprehensive utilization of crop stalks, and relates to a compound bacterial agent applied to efficient and fast rot of straws and its application in high-efficiency and fast rot of straws. Background technique [0002] In the context of depletion of available resources and increasingly severe environmental pollution, my country, as the country with the largest population base in the world, faces a more serious and complex energy strategy situation. At the same time, China is also a large agricultural country, and the annual crop straw residues (such as wheat straw, rice straw, sorghum stalks, corn stalks, hemp stalks, cotton stalks, etc.) reach 1.2 billion tons. Since my country's main crops are mainly wheat and rice, accounting for about 70% of the total straw, this is a huge renewable resource. However, random discarding and uncontrolled burning have not only caused serious environmental pollution but also a h...
