Plant protection liquid for agricultural products and preparation method

Abstract

The invention discloses a plant protection liquid for agricultural products and a preparation method thereof. The plant protection liquid comprises raw materials and auxiliary materials, wherein the raw materials comprise, by weight, 4-6 parts of xylosma and xylosma leaves, 5-6 parts of tobacco stems, 4-6 parts of licorice, 3-7 parts of rhizoma arisaematis, 8-9 parts of gastrodia elata, 5-7 parts of codonopsis pilosula, 4-6 parts of wormwood, 7-9 parts of miscellaneous tree leaves, 10-13 parts of weeds, 4-7 parts of aloe, 1-3 parts of Chinese asafetida, and 3-5 parts of Chinese honeylocust abnormal fruit. According to the plant protection liquid for the agricultural products and the preparation method, the high-concentration plant protection liquid is directly extracted by utilizing cheap raw materials and waste xylosma, weeds, tobacco leaves and other materials, the protection liquid can remove agricultural product residues and prevent various diseases and pests, and the plant protection liquid has the characteristics of no pesticide residues, no pollution, slight toxicity, difficulty in residue and the like; the safety of people is further ensured; the protection liquid has higher insect-killing and mosquito-repellent effects, increases the environmental protection, reduces the environmental pollution and improves the production efficiency of agricultural products.

Description

technical field [0001] The invention relates to the field of plant protection liquid, in particular to a plant protection liquid for agricultural products and a preparation method. Background technique [0002] Plant protectants are a class of low-molecular-weight antibacterial secondary metabolites produced or accumulated after plants are infected by pathogens or induced by various physiological, physical, and chemical factors. [0003] Oak leaf, the name of traditional Chinese medicine, is the branches and leaves of Xylosma racemosum (Sieb.et Zucc.) Miq., a plant of the Rhizoma family. It is distributed in the south of the Qinling Mountains and the south of the Yangtze River.

Problems solved by technology

[0004] At present, the preparation method of plant protection liquid for agricultural products, agricultural products in my country are often harmed by diseases and insect pests, and the main insecticides are controlled by highly toxic and high residual organic chemical insecticides. These insecticides have certain harm and pollution to the ecological environment. It is harmful to people's health. Although it reduces pesticide residues and heavy metal pollution to a certain extent, it cannot remove the hazards, and the production cost is relatively high. It is not suitable for various agricultural products.
