Plant protecting nutritional agent, preparation method thereof and amino acid water-miscible fertilizer containing plant protecting nutritional agent

Abstract

The invention relates to the field of agriculture and forestry, particularly to the technical field of pesticides, and more particularly to a plant protecting nutritional agent, a preparation method thereof and amino acid water-miscible fertilizer containing the plant protecting nutritional agent. In order to seek out a novel and environment-friendly pesticide, based on Chinese herbal medicine resources, the plant protecting nutritional agent is disclosed, through combining reactions of szechwan chinaberry fruits, flavescent sophora roots, tobacco leaves, stemona roots, tripterygium wilfordii, stellera chamaejasme, common monkshood mother roots, golden larch bark, silktree albizia bark, saponins, sinapis alba and licorice roots, only the extracting solution of the Chinese herbal medicines is used as the plant protecting nutritional agent, and effects of preventing and treating diseases and insect pests for plants and regulating nutrition are realized. At the same time, the amino acid water-miscible fertilizer containing the plant protecting nutritional agent is safe and environment-friendly, the fertilizer conforms to the use criterion of pollution-free food and organic food and has the advantages that the fertilizer can be repeatedly used without harm to people and livestock or phytotoxicity to the plants, the use cost is low, and the nutritional supplement is completed while insect pests and bacteria are killed.

Description

technical field

[0001] The invention relates to the field of agriculture and forestry, in particular to the technical field of pesticides, more specifically to a plant protection nutrient, a preparation method thereof and an amino acid water-soluble fertilizer containing the job protection nutrient.

[0002] Background technique

[0003] The application of pesticides is one of the important means to prevent and control diseases, insects and weeds, and to ensure a good harvest in grain production. With the continuous progress of scientific understanding, people are increasingly aware of serious problems such as environmental pollution, ecological imbalance, and human and animal poisoning caused by long-term use of chemically synthesized pesticides in large quantities. The sustainable development of society has attracted much attention. Therefore, people are eager to find new pesticides with unique mechanism of action and environmental friendliness.

Examples

Embodiment 1

[0025] According to 10~20 parts of Toosendan, 7~8 parts of Sophora flavescens, 6~7 parts of tobacco leaves, 5~6 parts of Baibu, 5~6 parts of Tripterygium wilfordii, 4~5 parts of chamaejamas, 3~4 parts of Aconitum, Weigh 5-6 parts of Vitex bark, 5-6 parts of Albizia juniperus, 4-5 parts of saponins, 3-4 parts of white mustard seeds, and 2-3 parts of licorice, and weigh the raw materials;

[0026] (2) Add more than 65% alcohol solution, and extract at room temperature for 40-60 minutes to obtain a plant protection nutrient solution.

Embodiment 2

[0028] First obtain the plant protection nutrient solution according to the method in Example 1, then use acid hydrolysis to obtain component A through deacidification and desalination steps respectively, obtain component B by protease fermentation and hydrolysis, and then first combine component A and component Part B is mixed in equal proportions to obtain plant-based amino acid solution, and then the plant protection nutrient solution is mixed with the plant-based amino acid solution to form a plant protection nutrient solution≥400g / L, NH≥100g / L, FA≥150g / L, NPK≥ 100g / L, organic matter ≥ 200g / L, pH 6.0~7.0, amino acid content ≥ 100g / L, trace elements ≥ 20g / L amino acid water-soluble fertilizer.

[0029] The method in Example 2 was used to obtain amino acid water-soluble fertilizer, which was used as the stock solution in the following examples.

Embodiment 3

[0031] Dilute the stock solution 500 times in the early stage of pests, mainly used as a preventive effect, and spray it on the plants in the form of spray; dilute the stock solution 400 times in the initial stage of pests, and spray it once every 5-7 days; Increase the dose, reduce the dilution factor, and spray the plants once every 3-5 days, and implement 2-3 times in a row.

[0032] Found common pests of food crops such as rice stem borer, rice planthopper, rice leaf roller, corn borer, armyworm; aphids, whitefly, cabbage caterpillar, diamondback moth, cabbage moth, scarab and other vegetable pests; apple Fruit tree pests such as leaf tortrix, cherry bee, cherry sawfly and citrus mites; tea pests such as tea black thorn whitefly, tea caterpillar, small green leafhopper, and tea weevil.
