Embodiment 1

[0020] A resistance enhancer for improving the ability of double-cropped cotton to resist Verticillium wilt, the resistance enhancer contains the following components in parts by mass: 10 parts of humic acid, 1 part of insecticide, 1 part of mancozeb, 2 parts of chlorothalonil, 3 parts of leek tobacco leaf extract, 1 part of copper sulfate, 2 parts of ammonium nitrate, 0.5 part of potassium borate, 0.1 part of plant growth regulator, 2 parts of organic solvent.

[0021] In this example, the preparation method of leek tobacco leaf extract is as follows: fresh leek and tobacco leaves are mixed and chopped according to the ratio of 1:4, added to the reaction kettle, immersed in 5 times the volume of absolute ethanol, and heated at 40°C The temperature of the water bath was cooked for 5 hours, and the ethanol solution containing the active substance was obtained by filtration; after the solution was absorbed, the gradient elution was carried out, and the eluate was sent to the evap...

Embodiment 2

[0027] A resistance enhancer for improving the ability of double cropping cotton to resist Fusarium wilt, the resistance enhancer contains the following components in parts by mass: 15 parts of humic acid, 2 parts of insecticide, 2 parts of mancozeb, 4 parts of chlorothalonil, 6 parts of leek tobacco leaf extract, 2 parts of copper sulfate, 3 parts of ammonium nitrate, 0.6 part of potassium borate, 0.3 part of plant growth regulator, 4 parts of organic solvent.

[0028] In this example, the preparation method of leek tobacco leaf extract is as follows: fresh leek and tobacco leaves are mixed and chopped according to the ratio of 1:4, added to the reaction kettle, and 8 times the volume of absolute ethanol is added to immerse, and the The temperature of the water bath was boiled for 6 hours, and the ethanol solution containing the active substance was obtained by filtration; the solution was adsorbed and then gradient eluted, and the eluate was sent to the evaporator for concent...

Embodiment 3

[0034] A resistance enhancer for improving the ability of double cropping cotton to resist Fusarium wilt, the resistance enhancer contains the following components in parts by mass: 13 parts of humic acid, 1.5 parts of insecticide, 1.5 parts of mancozeb, 3 parts of chlorothalonil, 5 parts of leek tobacco leaf extract, 1.4 parts of copper sulfate, 2.7 parts of ammonium nitrate, 0.5 parts of potassium borate, 0.2 parts of plant growth regulator, 3 parts of organic solvent.

[0035] In this example, the preparation method of leek tobacco leaf extract is as follows: fresh leek and tobacco leaves are mixed and chopped according to the ratio of 1:4, added to the reaction kettle, and 7 times the volume of absolute ethanol is added for immersion, and the mixture is heated at 43°C The temperature of the water bath was cooked for 5.5 hours, and the ethanol solution containing the active substance was obtained by filtration; after the solution was absorbed, the gradient elution was carrie...

Abstract

The invention relates to the technical field of cotton planting, in particular to a resistance enhancer for improving fusarium wilt resistance of cotton in continuous cropping. The resistance enhancercomprises humic acid, a pesticide, mancozeb, chlorothalonil, Chinese chive and tobacco extract, copper sulfate, ammonium nitrate, potassium borate, a plant growth regulator and an organic solvent. The Chinese chive and tobacco extract is extract obtained by digesting, filtering and repeated purification, and the active substance content of the extract is 3-6%; the pesticide is selected from one of abamectin, cypermethrin, fenpropathrin, thiacloprid, teflubenzuron and imidacloprid; the plant growth regulator contains indolebutyric acid, naphthylacetic acid, paclobutrazol, gibberellins, triiodobenzoic acid and diethyl aminoethyl hexanoate; the organic solvent is used for dissolving the plant growth regulator. The resistance enhancer can be sprayed in a cotton bud stage to improve fusarium wilt resistance of plants and increase yield of cotton in continuous cropping.

Description

technical field [0001] The invention relates to the technical field of cotton planting, in particular to a resistance enhancer for improving the ability of double cropping cotton to resist Fusarium wilt. Background technique [0002] Cotton is a plant that can provide natural plant fiber products. It is a crop with important strategic value. The cotton fiber in cotton has good toughness, high strength, excellent elasticity, chemical stability and moisture absorption performance. It is the best fabric fiber. Clothing made of cotton has good warmth retention, strong air permeability, and has excellent skin-friendly properties, making it very comfortable to wear. [0003] Cotton is planted in large quantities in the west of my country. The soil and hydrological conditions in these areas are poor, but the light and heat conditions are good, which is very suitable for cotton planting. Due to limited land resources, high-quality arable land needs to meet the production of food cr...
