Abstract

The invention provides a microbial agent for preventing and treating southern blight of crops and a preparation method of the microbial agent, and belongs to the technical field of biological products. The microbial agent comprises the following components in parts by weight: 15-25 parts of trichoderma, 15-25 parts of bacillus subtilis, 25-35 parts of saccharomycetes and 1500-2500 parts of an amino acid; the preparation method of the microbial agent comprises the following steps: adding trichoderma, bacillus subtilis, saccharomycetes and amino acid into a fermentation tank, adding 7000-8000 parts of water, uniformly stirring, and carrying out anaerobic fermentation at 22-27 DEG C for 40-60 hours, thereby obtaining the microbial agent. The microbial agent disclosed by the invention containsmetabolic products of three kinds of microorganisms and three active microorganisms, and ketone substances, such as eurycomanone, are generated in fermentation metabolites; because of cooperation ofthe various fermentation products and the three microorganisms, crop southern blight can be prevented and treated effectively.

Description

technical field [0001] The invention relates to the technical field of biological products, in particular to a microbial bacterial agent for preventing and treating the mildew of agricultural crops and a preparation method thereof. Background technique [0002] Sclerotia, also known as sclerotinia root rot and sclerotia seedling blight, harms the roots and stems of seedlings and young trees; the asexual generation of the pathogen is neat small sclerotia Seleroium rolfsii Sacc. , Sclerotinia. [0003] Symptoms: Usually occur at the rhizome or stem base of seedlings. The cortex of the infected rhizome gradually turns brown and necrotic, and the cortex is severely rotted. After the seedlings are damaged, the absorption of water and nutrients will be affected, resulting in poor growth, the leaves above the ground will become smaller and yellow, the internodes of the branches will be shortened, and the branches and leaves will wither in severe cases. When the disease spots ring...
