Biological organic water-soluble fertilizer for preventing and treating bacterial wilt of vegetables and preparation method of biological organic water-soluble fertilizer

Abstract

The invention relates to a biological organic water-soluble fertilizer for preventing and treating bacterial wilt of vegetables and a preparation method of the biological organic water-soluble fertilizer. The biological organic water-soluble fertilizer comprises an A group of effective components and a B group of effective components, wherein the A group contains the following raw materials in parts by weight: 460-540 parts of concentrated molasses ferment powder, 5-15 parts of calcium polyaspartate, 0-30 parts of paenibacillus polymyxa, 10-30 parts of bacillus cereus and 5-15 parts of bacillus subtilis; and the group B contains the following raw materials in parts by weight: 0.5-1.5 parts of 80% mevalonic acid, 0.5-1.5 parts of 1.51% Yun alcohol powder, 6-10 parts of small-molecule water-soluble chitosan, 5-15 parts of disodium octaborate tetrahydrate, 80-120 parts of potassium humate, 3-7 parts of EDTA manganese, 3-7 parts of EDTA zinc, 80-120 parts of ammonium low-polysphate, 80-120 parts of dipotassium phosphate and 80-120 parts of potassium tripolyphosphate. The biological organic water-soluble fertilizer has good prevention and treatment effects, long lasting period, has no toxicity or residue, is harmless to people and livestock and low in use amount and cost and does not pollute the environment.

Description

technical field [0001] The invention belongs to the field of vegetable bacterial wilt prevention and control, in particular to a bio-organic water-soluble fertilizer for preventing vegetable bacterial wilt and a preparation method thereof. Background technique [0002] Vegetable bacterial wilt, also known as bacterial wilt, is a bacterial vascular disease and is the main disease of tomato, eggplant, pepper, potato and other solanaceous vegetables. The main symptom is that the plants wilt and die quickly, and the stems and leaves remain green. The browning part of the diseased stem is squeezed by hand, and milky white bacteria liquid is discharged. The disease is prone to occur under the conditions of high temperature and high humidity, continuous cropping, low-lying soil, water accumulation in the field, acidic soil, and partial application of nitrogen fertilizers. Therefore, the pathogen has the characteristics of a wide range of hosts, strong stress resistance, and is di...

AI Technical Summary

Problems solved by technology

Although this type of method can achieve the control effect to a certain extent, it is labor-intensive and time-consuming, the application should be uniform, and it is easy to damage the plants; ③ chemical control

Commonly used pesticides such as streptomycin for agriculture, 40% Yekuning, 25% copper ammonia water, 50% chlorothalonil, 25% Qingkuling, etc. are used for prevention and treatment, but their effects are poor, pollute the environment, and have residues. Harmful to the human body; ④ grafting for disease prevention, using disease-resistant rootstocks for grafting to prevent and control bacterial wilt, which is labor-intensive and time-consuming, and the price of rootstocks is high
