Temperature-sensitive trichoderma harzianum microbial agent carrier formula and preparation process thereof

Abstract

The invention relates to the technical field of biology and particularly relates to a temperature-sensitive trichoderma harzianum microbial agent carrier formula and a preparation process thereof. The temperature-sensitive trichoderma harzianum microbial agent carrier formula is characterized by being composed of the following raw materials in percentage by weight: 35%-45% of organic matter decomposed coal, 25%-35% of humic acid, 15%-25% of trichoderma harzianum fermented raw liquid and 5%-15% of diatomite. Compared with the prior art, a biological probiotic can be applied to various facilities including outdoor cultivation, greenhouse cultivation and the like, can be used for repairing soil and preventing soil-borne diseases, such as stem rot, wilt, damping-off, stalk break, rhizoctonia solani and root rots of various vegetables, grain crops, fruits, medicinal materials, flowers, nursery-grown plants and the like; microbes such as trichoderma harzianum and pathogenic bacteria interact; essentially, three organisms including trichoderma harzianum, plants and pathogenic bacteria interact.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a thermosensitive Trichoderma inoculum carrier formulation and a preparation process thereof. Background technique [0002] Use biological beneficial bacteria to develop and prevent soil-borne diseases, focusing on microbial soil-borne pathogens in soil-borne diseases. Soil-borne pathogens generally infect through soil and invade plant roots, stems, leaf orifices or wounds, causing crop root and even whole plant diseases, causing serious economic losses. At present, chemical control and screening of crop resistant varieties are commonly used, which are only effective for a few soil-borne diseases and have little effect on most soil-borne diseases. Moreover, the use of chemical pesticides will also cause pesticide residues and pollute the environment. At the same time, the long-term use of chemical pesticides will increase the resistance of pathogenic bacteria, resulting in a dec...

Problems solved by technology

Soil-borne pathogens generally infect through soil and invade plant roots, stems, leaf orifices or wounds, causing crop root and even whole plant diseases, causing serious economic losses

At present, chemical control and screening of disease-resistant crop varieties are commonly used, which are only effective for a few soil-borne diseases, and have little effect on most soil-borne diseases, and the use of chemical pesticides will also cause pesticide residues and pollute the environment

At the same time, the long-term use of chemical pesticides will increase the resistance of pathogenic bacteria, resulting in a decline in the control effect or even failure.
