Abstract

The invention relates to a composite biological preparation and application thereof in elimination of meloidogyne. The active component contained in the composite biological preparation is a nematodecontrol composition, which contains algae polysaccharide, xylanase, cellulase, protease and beta-glucosidase. The composite biological preparation prepared with the composition is soluble in water, can be added into irrigation liquid and seep into the soil at the same time of irrigation, thus achieving the meloidogyne control effect, the composite biological preparation also can be applied to irrigation treatment on soil before plant sowing, and the use method is simple and effective. The composite biological preparation can reach a nematode control rate up to 90% or more, also is non-toxic and harmless to animals and plants, and is low in cost, thus being suitable for mass production and promotion.

Description

technical field [0001] The invention relates to the technical field of biological control, in particular to a compound biological preparation for controlling root-knot nematode and its application. Background technique [0002] Root-knot nematode Meloidogynes pp. is a soil-borne pathogen, which is a bilaterally symmetrical, colorless, transparent invertebrate. The nematode body can be divided into body wall and body cavity. The body wall is composed of cuticle, subdermis and muscle from the outside to the inside. Inside the body wall is the body cavity, which is filled with body fluid used to moisten various organs. This liquid As the original blood of nematodes, it supplies the nutrients and oxygen needed by the nematodes. Nematodes harm the plant root system, induce plant root distortion to form "tumor-like" protrusions, cause plant physiological lesions, affect plant growth and development, and cause crop quality to decline, yield reduction by 20-40%, severe yield reduct...
