preparation example Construction

[0038] The preparation method reference example 1 of tobacco leaf extract

[0039] Crush 1 part by weight of dried tobacco leaves to pass through a 10-mesh sieve, add 12 parts by weight of water, adjust the pH value to 11, heat and leach at 50°C for 1.5 hours, filter, and concentrate the filtrate to a moisture content of 25%. Tobacco leaf extract 1 was obtained.

[0040] The preparation method reference example 2 of tobacco leaf extract

[0041] Crush 1 part by weight of dried tobacco leaves to pass through a 10-mesh sieve, add 10 parts by weight of water, adjust the pH value to 12, heat and leach for 2.0 hours at 40°C, filter, and concentrate the filtrate to a moisture content of 20%. Tobacco leaf extract 2 was obtained.

[0042] The preparation method reference example 3 of tobacco leaf extract

Abstract

The invention discloses a composition for biologically preventing and treating cotton blight and verticillium wilt as well as a preparation method and application of the composition. The composition mainly comprises the following components: a tobacco leaf extract, a cirsium setosum extract, a bacillus subtilis preparation, a paecilomyces lilacinus preparation, a streptomyces scab preparation, gamma-aminobutyric acid and an organic material. The invention further discloses a preparation method and application of the composition for biologically preventing and treating cotton blight and verticillium wilt. The composition can eradicate cotton blight and verticillium wilt, increase the yield, improve soil organic matter, improve soil fertility, is environmentally friendly and low in cost, andachieves sustainable utilization of soil. The method and application are simple, and the method is suitable for agricultural production.

Description

technical field [0001] The invention relates to a composition for preventing and treating cotton fusarium wilt, a preparation method and application thereof, in particular to a composition, a preparation method and application for biologically controlling cotton fusarium wilt. Background technique [0002] China is one of the major cotton producing areas in the world, and as the biggest cotton disease, the occurrence of cotton fusarium wilt, known as the "cancer" of cotton, greatly limits the increase of cotton production in China. Cotton Fusarium wilt occurs in the main cotton-growing areas, and the northern cotton area is more serious than the Yangtze River Basin cotton area. In China, cotton verticillium wilt is caused by Verticillium dahliae, the pathogen of cotton verticillium wilt, and occurs in cotton stems, branches, and leaves. How to prevent and control through pollution-free is an important subject to be studied for cotton quality assurance and income increase. ...
