Bacillus psychrosaccharolyticus strain and application thereof in complex microorganism seaweed fertilizer

Abstract

In the invention, a bacillus psychrosaccharolyticus obtained by screening is used for preparing an efficient complex microorganism seaweed fertilizer. The bacillus strain in the invention is named as bacillus psychrosaccharolyticus and preserved in the Common Microorganism Center under China Microorganism Strain Preservation and Management Committee with a preservation number of CGMCC No.4519. The bacillus psychrosaccharolyticus not only has the capacity of carrying out forced degradation on cellulose and starch but also has a wide antimicrobial spectrum; the bacillus psychrosaccharolyticus strain can be compounded with the traditional common strain for bacterial manure; then mixed zymocyte liquids, plant growth factors, immunoregulation factors, active extractives from seaweed, amino acids, organic matters and trace elements are prepared into an efficient complex mircoorganism seaweed fertilizer with an active viable count of 0.2 billion / g to 1 billion / g and an organic matter content of 20-40% according to a certain proportion. The fertilizer has remarkable capacity in combating plant diseases and insect pests and promoting growth. With the fertilizer, the yield of crops can be increased by more than 30%.

Description

technical field [0001] The invention relates to a strain of Bacillus pyrolyticum and its application in compound microbial seaweed fertilizer. Background technique [0002] Soil-borne diseases appearing in various parts of our country are becoming more and more serious and are on the rise. Fusarium wilt, nematode disease, blight and viral diseases are spreading. The use of a large number of chemical fertilizers and pesticides, on the one hand, has solved the problem of food supply and increased economic income; but on the other hand, chemical pesticides have also brought about more serious negative effects: low fertilizer utilization rate, environmental degradation, land quality decline, Water pollution and the decline of crop disease resistance have largely threatened food security and the sustainable development of agriculture. Microbial fertilizer has its unique function in solving this problem and has achieved good results. It will be the focus and support of the develo...
