Abstract

The invention discloses an application process for trichodermin preventer, and belongs to application of microorganisms. The application process for the prior trichodermin preventing products has heavy labor, poor sporegermination and non-ideal colonization. The application process for the trichodermin preventer is to spread the trichodermin preventer comprising a trichodermin spore agent and a nutrient medium on the surface of moist soil to accelerate the growth and propagation of trichodermin. The implementation of the application process comprises the following steps: firstly performing irrigation, water spray, water sprinkle or drop irrigation, and infiltrating irrigation to moisten the soil; and then spreading the trichodermin preventer on the surface of the moist soil. The application process is simple and practical, saves labor and is easy to be accepted by users. The trichodermin preventer is applied by the application process, and the nutrient medium on the surface of the soil provides nutrient to the trichodermin to accelerate the growth and propagation of the trichodermin so as to prevent fungal diseases on roots and bud bases of plants and simultaneously prevent the fungal diseases on stems, leaves, flowers and fruits of the plants.

Description

technical field [0001] The invention belongs to the field of microorganism application, and in particular relates to an application method of a trichoderma biological control agent. Background technique [0002] Nowadays, plant fungal diseases have restricted the high yield, stable yield and high quality of crops. With people's increasing requirements for pollution-free and pollution-free green organic food, experts and scholars have spared no effort in the research of biological control without chemical pesticide residues, and have screened out such as Trichoderma harzianum, Trichoderma viride, Trichoderma longibrachiae, Some Trichoderma fungi that have the function of antagonizing disease fungi and can be used for biological control, such as Trichoderma konii, Trichoderma hacinata, Trichoderma chrysopride and Trichoderma citrus viride. The number of Trichoderma biological control agents developed and registered at home and abroad in recent years with Trichoderma fungus as...
