Abstract

The invention discloses a compound microbial fertilizer for antagonism of soil-borne fungal diseases, and a preparation method and an application thereof; the fertilizer takes humic acid as a compound carrier, includes bacillus amyloliquefaciens HFJ-7 with the bacteria content of 1.8*10<8>-2.1*10<8> CFU / g, and also includes bacillus megatherium B3. The bacillus amyloliquefaciens HFJ-7 in the compound microbial fertilizer has the preservation number of CGMCC No.10011. The bacillus amyloliquefaciens HFJ-7 strain can be antagonistic to rhizoctonia solani, fusarium oxysporum, root rot pathogen, cucumber fusarium wilt pathogen, phytophthora capsici leon pathogen and other soil-borne disease pathogenic fungi. After the bacillus amyloliquefaciens HFJ-7 is compounded with the bacillus megatherium B3, the resistance to rhizoctonia solani and pepper root rot pathogen can be significantly improved, a disease state index of pepper seedling root rot disease can be significantly reduced, and the occurrence and spreading of pepper root rot can be effectively prevented and controlled.

Description

technical field

[0001] The invention belongs to the field of biological fertilizers and relates to the preparation and application of compound microbial fertilizers, in particular to a compound microbial fertilizer for antagonizing soil-borne fungal diseases and its preparation method and application. Background technique

[0002] In recent years, great progress has been made in the control of plant diseases by bacteria. According to reports in the United States, the effect of using Erwinia herbophilus to control amylovora is equivalent to that of streptomycin. The Biological Pesticide Engineering Center of Shenyang Agricultural University used antagonistic Trichoderma and antagonistic bacteria to make a powder, which successfully prevented the seedling diseases of protected vegetables and melons. The product is in the pilot stage. Other reported bacterial fungicides include: Bacillus licheniformis used to control cucumber and tobacco anthracnose, Bacillus subtilis to contr...
