Synergist and functional compound fertilizer for preventing and treating plant root-knot nematodes

Abstract

The invention provides a synergist for preventing and treating plant root-knot nematodes, wherein the synergist comprises alkali lignin, a biological enzyme and nematode-resistant functional microorganisms, and the mass ratio of the alkali lignin to the biological enzyme to the nematode-resistant functional microorganisms is (5-15):(1-10):(1-7). The synergist for preventing and treating plant root-knot nematodes provided by the invention not only can effectively solve the harm of plant root-knot nematodes, but also can loosen and improve soil, increase the number of beneficial microorganisms in soil and increase the content of organic matters in soil on the premise that farmland fertilizers (chemical fertilizers) can be normally used.

Description

technical field [0001] The invention belongs to the technical field of pest control of crops, and in particular relates to a synergist for preventing and controlling plant root-knot nematodes and a functional compound fertilizer for preventing and controlling plant root-knot nematodes. Background technique [0002] Plant root-knot nematode is a highly specialized omnivorous plant pathogenic nematode. There are 54 species of root-knot nematodes that parasitize plants, of which about 15 species are relatively common. Root-knot nematodes mainly harm the roots of plants, resulting in weak plant growth, and even yellowing and death. In severe cases, it affects crop yield and quality. The causes of root-knot nematodes are: first, unreasonable fertilization, excessive and blind application of chemical fertilizers, and insufficient use of organic fertilizers, resulting in the reduction of beneficial microorganisms in the soil, the increase of harmful bacteria, and the increase of so...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a synergist for preventing and treating root-knot nematodes and a functional compound fertilizer for controlling root-knot nematodes, aiming to solve the problem of root-knot nematode control using only organic fertilizers or functional microorganisms. , the efficiency is low and the effect is not good, and at the same time, it cannot provide balanced nutrition to the plants. However, the existing methods of using chemical pesticides to control plant root-knot nematodes cause a large amount of pesticide residues, which affect human health, and the cost of pesticides is relatively high.
