Biological organic fertilizer for preventing and treating root-knot nematode and preparation method and application of biological organic fertilizer

Abstract

The invention provides a biological organic fertilizer for preventing and treating root-knot nematode and a preparation method and application of the biological organic fertilizer. The biological organic fertilizer comprises 5-30 parts of a composite bacterial agent and 70-95 parts of a carrier, wherein the composite bacterial agent contains bacillus subtilis, paecilomyces lilacinus, pochonia chlamydospora and streptomycete, and the carrier is made from chicken manure, mushroom residues, and rape seed cake through microorganism compost fermentation. The composite bacterial agent has the effectof preventing and treating root-knot nematode in soil. The carrier is abundant in organic components and inorganic components, which can improve soil, increase the nutritive components in soil, accelerate the effective colonization of the composite bacterial agent in soil, and improve the capability of controlling treating root-knot nematode in soil of the composite bacterial agent. The providedbiological organic fertilizer for preventing and treating root-knot nematode is powder, can be used as a base fertilizer, is harmless to human and animals, is good in preventing and treating effect, and can obviously improve the quality and yield of crops.

Description

technical field [0001] The invention relates to the field of organic fertilizers, in particular to a bio-organic fertilizer for preventing and controlling root-knot nematodes and its preparation method and application. Background technique [0002] Root-knot nematode is an important group of plant parasitic nematodes and a major soil-borne disease that harms crops. It has a wide variety and a wide range of hosts, which seriously affects the production of crops and brings huge losses to crops every year. Root-knot nematode infects the roots of crops, affects the growth and development of crops, reduces crop quality, and causes crop yield reduction or even failure. In addition, root-knot nematodes further aggravate the spread of plant bacterial and fungal diseases by parasitizing among plants. At present, the main method of controlling plant root-knot nematodes is chemical agents. The perennial use of chemical agents not only brings food safety hazards such as pesticide resi...

AI Technical Summary

Problems solved by technology

It has a wide variety of species and a wide range of hosts, which seriously affects the production of crops and brings huge losses to crops every year

Root-knot nematodes affect the growth and development of crops by infecting the roots of crops, reduce crop quality, and cause crop yield reduction or even failure

In addition, root-knot nematodes further aggravate the spread of plant bacterial and fungal diseases through their parasitism among plants

At present, the main method of controlling plant root-knot nematodes is chemical agents. The use of chemical agents all year round not only brings food safety hazards such as pesticide residues to agricultural products, but also brings a series of problems such as water and soil pollution and ecological damage to the environment.
