Abstract

The invention relates to a soil improvement agent trichoderma atroviride DQ1 composite powder TLB, and applications thereof. The soil improvement agent trichoderma atroviride DQ1 composite powder TLB is prepared via following steps: 1, PDA slant culture-medium is inoculated with trichoderma atroviride DQ1 so as to obtain a spore liquid, and sterilized PD culture medium is inoculated with the spore liquid for culturing; 2, a pore suspension liquid is prepared from wheat bran, diatomite, rice husk, and water, and is taken as a solid shallow tray fermentation seed liquid; 3, a solid shallow tray fermentation medium is prepared from wheat bran, diatomite, streptomycin, and sterile water at a mass ratio of 50:25:1:50, is stirred, and is sterilized, the sterilized solid shallow tray fermentation medium is mixed with the solid shallow tray fermentation seed liquid, culturing is carried out, an obtained shallow tray fermentation product is subjected to air drying and smashing so as to obtain trichoderma atroviride DQ1 spore powder; and 4, the soil improvement agent trichoderma atroviride DQ1 composite powder TLB is prepared. The soil improvement agent trichoderma atroviride DQ1 composite powder TLB is capable of preventing and treating vegetable soil borne diseases, and is harmless for human and animals, and no environment pollution is caused.

Description

1. Technical field [0001] The invention relates to a biological bacterial agent for preventing and controlling crop diseases, in particular to a soil improver Trichoderma dark green DQ1 composite powder TLB and an application thereof. 2. Background technology [0002] With the growth of crop planting years, the planting pattern is relatively fixed, resulting in the accumulation of a large number of harmful organisms in the soil, and the occurrence of diseases is becoming more and more serious. In addition, the continuous cultivation of the soil has caused obvious changes in the physical properties of the soil, and a large amount of compaction of the soil. Therefore, soil-borne diseases and soil fertility decline have become important limiting factors affecting crop production. However, the current prevention and control of crop diseases mainly relies on chemical means. As we all know, chemical pesticides have residues in crops, air, water and soil, causing excessive pesticid...
