Embodiment Construction

[0007] 1. The cultivation process of Trichoderma viride

[0008] Using the formula of 78% broad-leaved tree (oak tree, birch) sawdust, 20% wheat bran, 1% white sugar and gypsum, after autoclaving, inoculate and manage according to the normal aseptic operation method, and choose the fungus bag contaminated by Trichoderma viride as the biological Antimicrobial agents.

[0009] 2. Leguminous forage root rot fungus

[0010] Root rot often occurs in the planting process of alfalfa and fodder soybeans. Generally, the incidence in the field is 5% to 30%. Severe plots lead to lack of seedlings and broken bars. The main pathogens are Fusarium, Rhizoctonia and Pythium Wait. It is a type of soil-borne soil habituating fungus.

[0011] 3. Treatment methods and management techniques

[0012] During the sowing period of leguminous pasture, according to 5kg / 666.7m 2 The dose and seed fertilizer are applied to the sowing ditch together, and other field management is the same as that of t...

Abstract

The invention discloses a method for controlling legume root rot by using trichoderma viride in pollution materials in the production process of edible mushrooms. According to the invention, xylosma / birch wood dusts and wheat bran are used as main raw materials to cultivate the breeder seeds and cultivars of edible mushrooms and the raw materials polluted by trichoderma viride bacteria in the production process are used; and the raw materials are applied to the field along with the seed fertilizer during sowing, so that the invasion of root rot bacteria in the soil is controlled. The trichoderma viride is widely distributed in natural world and is often saprophytic in residues of timers, seeds and plants. The trichoderma viride is capable of producing a plurality of enzymes with biological activity, such as cellulose, chitinase, xylanase, and has important function in pathological and biological control of plants. The trichoderma viride is applied to fields along with the seeds during the sowing of legumes, shows double efficacies of protection and treatment and is capable of effectively controlling soil-borne root rot.

Description

technical field [0001] The invention relates to a method for biological control of pasture diseases in artificial grasslands. Background technique [0002] With the vigorous development of edible fungus industrialization, edible fungus cultivation waste (fungus chaff) has brought serious pollution to the environment and caused a waste of resources. The research on the reuse of fungus chaff has attracted much attention. Root rot occurs seriously in artificial grassland production, which reduces the yield and quality of forage grass and restricts the development of artificial grassland industrialization. Exploring efficient and green biological agents to control diseases is an urgent problem to be solved in production. In 1932, Weindling discovered that Trichoderma lignorum can parasitize a variety of plant pathogenic fungi, and suggested that the fungus be used for the biological control of soil-borne plant diseases, and the research on the biocontrol of Trichoderma began fr...
