Problems solved by technology

[0004] The prior art mainly carries out chemical control before and at the beginning of the onset, and sprays agricultural streptomycin or neophytomycin, dexonium powder, ammonium methionine, copper hydroxide, and chloramphenicol on the petiole base and stem base near the ground. But the current control effect is not ideal: the control effect is poor, and the antibiotics used to prevent soft rot are expensive, and there will be problems of drug resistance

Abstract

The invention discloses a preparation method and application of a matrix for preventing and treating vegetable soft rot, and belongs to the technical field of preventing and controlling vegetable soft rot. First japonica rice and corn are sterilized, pulverized, and sieved; then mixed with water according to the mass ratio of 1: (0.1-0.3) as japonica rice culture medium and corn culture medium, and inoculated with 1 g of japonica rice culture medium for 10 5 -10 8 Monascus spores were inoculated, and 1 g of corn medium was inoculated for 10 5 -10 8 Aspergillus oryzae spores were inoculated and fermented at 25-40°C for 6-15 days to obtain japonica rice fermentation products and corn fermentation products; the corn fermentation products and japonica rice fermentation products were mixed to obtain a substrate for the prevention and treatment of vegetable soft rot; specific application: first in the ditch According to the prevention and treatment of vegetable soft rot substrate and seed mass ratio is (50-500): 1 or 5g-30g / hole sowing prevention and control vegetable soft rot substrate, then sowing vegetable seeds or planting seedlings, the anti-efficiency to vegetable soft rot can be achieved Up to 88.5% or more.

Description

technical field [0001] The invention belongs to the technical field of preventing and treating vegetable diseases, and relates to the technology of preventing and treating vegetable soft rot, in particular to a method for preparing a substrate for preventing and controlling vegetable soft rot, and the application of the prepared substrate for preventing and controlling vegetable soft rot. Background technique [0002] Soft rot, caused by bacteria of the genus Erwinia and fungi of the genus Rhizopus, rots plant tissues or organs. The pathogens are all weak parasites, which mainly harm the juicy and plump organs of plants, such as roots, tubers, fruits, stem bases, etc.; and the pathogens are mainly accompanied by diseased plants and diseased residues in soil, compost, vegetable pits or seedlings. Infection and reproduction can also be invaded from plant wounds with the help of insects, irrigation water, and wind and rain. High density of chewing mouthparts insects, early sow...
