Problems solved by technology

Among them, Paecillin lilacin, Puccinia pachytansporum, Abamectin, Bacillus, etc. are more common, and the control efficiency is about 40-60%. The effect of controlling root-knot nematode is better, but the effective strain is single , resulting in a single biocontrol mechanism, no synergistic effect between strains, and no further improvement in control efficiency

Abstract

The invention provides a biological control method for peanut root-knot nematode disease, including the steps of firstly, preparing biological fermentation liquid by using human and livestock manure,furfural residues, fly ash, activated sludge treatment liquid, and a composite fermentation preparation as raw materials, then soaking seeds with the biological fermentation liquid, digging low ridges, sowing at the bottom of the ridges, and spraying diluted biological fermentation liquid before and after sowing.Through pretreatment of peanut seeds and improvement of the sowing environment, the incubation of root-knot nematode eggs and infestation of root-knot nematodes on peanut roots can be effectively inhibited, and the method is safe and effective in preventing and controlling peanut root-knot nematodes.In addition, the biological fermentation liquid is rich in beneficial active bacteria, which can improve the growth environment of peanut root systems, and promote the absorption of water and nutrients by the peanut root systems, thereby increasing yield and quality.

Description

technical field [0001] The invention relates to the technical field of peanut planting, in particular to a method for biological control of peanut root-knot nematode. Background technique [0002] Peanut root-knot nematode (Peanut Root Knot Nematode) is also known as peanut nematode disease, commonly known as ground yellow disease, ground drop disease, dwarf yellow disease, yellow seedling disease, etc. Peanut root-knot nematode is a worldwide disease that occurs in almost all countries and regions where peanuts are grown. It was first discovered in Shandong Province in China, and currently occurs in Shandong, Anhui, Jiangsu, Hebei, Beijing, Liaoning, Jilin, Henan, Hunan, Hubei, Guangdong, Guangxi, Guizhou, Shaanxi, Gansu, Hainan and other provinces (cities, districts) Among them, Shandong is the most common. After peanut infection, the absorption function of the roots is destroyed, the plants are short and yellow, and the results are few and sparse. Generally, the produc...
