Problems solved by technology

Agricultural control measures are mainly crop rotation and selection of disease-resistant varieties, but crop rotation often limits the stable development of pepper planting, and cannot meet the requirements of large-scale production of peppers; breeding of disease-resistant varieties takes a long time, and the varieties are easy to resist. lost
Commonly used chemicals for chemical control include chlorothalonil, azoxystrobin, ketoxal, metalaxyl, zinc zinc, etc., which are the most commonly used control measures. However, due to the high frequency and large amount of chemical agents, they are easy to accumulate in the soil , seriously affecting the safety of agricultural products and human health, and due to the continuous rise in the resistance of pathogens, the control effect is gradually declining

Embodiment 1

[0029] Mix molasses and biogas slurry at a mass ratio of 1:1 as the liquid organic material of the organic preparation, adjust the carbon-to-nitrogen ratio of the liquid organic material to 25-35:1, Trichosporium dermatoides is used as a decomposition-promoting ingredient, and the liquid organic material The mass ratio of the decomposition-promoting ingredient is 95:5, and then 100ng / kg of liquid organic material is added to pyrroloquinoline quinone, and the above-mentioned raw materials are mixed at a mixing speed of 50-100r / min. After fully mixing, dry and concentrate at 30-40°C for 10 -30min, naturally cooled to room temperature.

Embodiment 2

[0031]Mix molasses and biogas slurry at a mass ratio of 1:2 as the liquid organic material of the organic preparation, adjust the carbon-to-nitrogen ratio of the liquid organic material to 25-35:1, and use pectinase as a decomposition-promoting ingredient. The mass ratio of decomposed ingredients is 97:3, and then add pyrroloquinoline quinone at 200ng / kg of liquid organic materials, mix the above raw materials at a mixing speed of 50-100r / min, fully mix and then dry and concentrate at 30-40°C for 10-30min , naturally cooled to room temperature.

Embodiment 3

[0033] Mix molasses and biogas slurry at a mass ratio of 1:3 as a liquid organic material for organic preparations, adjust the carbon-to-nitrogen ratio of the liquid organic material to 25-35:1, and use jelly-like bacillus and thermophilic bifidobacteria as decomposition-promoting ingredients , the mass ratio of the liquid organic material and the decomposition-promoting ingredients is 99:1, then add pyrroloquinoline quinone by 300ng / kg liquid organic material, mix the above-mentioned raw materials, the mixing speed is 50-100r / min, after fully mixing, the mixture is mixed at 30 Dry and concentrate at -40°C for 10-30 minutes, then cool naturally to room temperature.

Abstract

The invention belongs to the technical field of insect and disease prevention and treatment and in particular relates to an organic preparation for preventing and treating pepper phytophthora blight and elsinoe leucospila and a preparation and use method of the organic preparation. The organic preparation provided by the invention comprises a liquid organic material, a decomposition promotion material and pyrroloquinoline quinine, wherein the liquid organic material is composed of molasses and biogas slurry in a mass ratio of 1:(1-5); the decomposition promotion material comprises a at least one of a microorganism preparation and an organic catalyst; and the use amount of the pyrroloquinoline quinine is 100-300ng / kg of the liquid organic material. The organic preparation is prepared according to a certain method and is applied into soil, anaerobic treatment is implemented after watering and film covering, pathogenic bacteria, namely pepper phytophthora blight and pepper phyllosticta inthe soil can be effectively killed, the incidence rate of pepper phytophthora blight and elsinoe leucospila can be reduced, meanwhile, the yield and the quality of pepper can be improved, and the organic preparation is green, environment-friendly and efficient, and has certain application prospects.

Description

technical field [0001] The invention belongs to the technical field of disease and insect pest control, and in particular relates to an organic preparation for preventing and treating capsicum blight and white spot disease, and a preparation and use method thereof. Background technique [0002] Capsicum is an annual or limited perennial herb of the genus Capsicum in the family Solanaceae, and it is an important vegetable crop in my country. Pepper is native to the tropical regions of Central and Latin America. The country of origin is Mexico. In China, it is mainly distributed in Sichuan, Guizhou, Hunan, Yunnan, Shaanxi, Henan, Jize County of Hebei Province and Tuoketuo County of Inner Mongolia. The original distribution area of ​​this species is from Mexico to Colombia, and now it is widely cultivated in countries all over the world. [0003] Capsicum blight is a soil-borne disease caused by Phytophthora capsici, which occurs worldwide and in pepper producing areas in vari...
