Natural plant biological composite nutrient solution for killing nematode and preparation method thereof

Abstract

The invention relates to a natural plant biological composite nutrient solution for killing nematode and a preparation method thereof. The natural plant biological composite nutrient solution for killing nematode comprises bacillus subtilis bacillus subtilis, paecilomyces lilacinus, beauveria bassiana and plants marigold flower, stemona, maidenhair, sophora flavescens, derris trifoliata, melia azedarach and protein liquid according to weight ratio, compared with prior art, the natural plant biological composite nutrient solution has beneficial effects that harm due to soil borne parasites such as root-knot nematode, heterodera sachachtii, and ditylenchus dipsaci can be effectively prevented and treated; no pesticide residue on soil and crops fruits can be realized, usage is convenient, no pollution is generated, nematode harm can be avoided by using the solution for three times in a whole fertility period, and the nutrient solution creates condition for producing green organic food; and has good prevention and treatment effects for crop soil borne disease, can improve the soil and increase soil granular structure, and is capable of preventing soil hardening, increasing the content of the organic matter, dissolving phosphor, releasing potassium and fixating nitrogen, as well as supplementing crop nutrition.

Description

Technical field [0001] The present invention relates to a plant insecticide and a production method thereof, in particular to a liquid that kills nematodes, is compounded from natural plants and organisms, and is supplemented with nutrients, and a preparation method thereof. Background technique [0002] The early research work on root-knot nematode biological control was mainly in France, the United States, the United Kingdom and the former Soviet Union. Their results of taxonomic and ecological research on nematode fungi provided detailed information for the biological control of root-knot nematodes and other plant parasitic nematodes. data. However, early research work was not effective in preventing and controlling plant parasitic nematodes, causing some people to lose confidence in controlling the harm of nematodes, and it is difficult for scientists interested in this research to get the necessary support. Therefore, the control of nematodes mainly relies on chemical n...

Problems solved by technology

The long-term use of existing nematicides will cause harm to the soil environment, increase pesticide residues in crops, and affect quality; the use time and method are limited; the drug effect is short, and the control effect is not ideal; green organic food cannot be produced
