Problems solved by technology

[0003] Machine-picked cotton must be sprayed with ripening agent and defoliation agent before harvesting, and it takes about 15-20 days for the effect of the defoliation agent (hormone-regulated type) to play its role. At this time, cotton is at the key to ripening autumn peach D

Embodiment 1

[0017] A cotton defoliant, weighed 50g of thiadizuron, 20g of pyriflurone, 10g of pyridoxone, 100g of organic bentonite, 30g of wetting and dispersing agent, 10g of defoaming agent and 20g of deionized water.

[0018] Among them, the defoaming agent is an equal mixture of polydimethylsiloxane and polyoxypropylene, and the wetting and dispersing agent is sodium lignosulfonate.

[0019] The preparation method of the cotton defoliation agent is to take deionized water and add it to thiadizuron for dilution, then add pyrimiazide and pirazole to obtain a mixed solution; grind organic bentonite until the particle size is ≤1mm, and add it to the above mixed solution In the process, stir evenly; finally, at a temperature of 42°C, add wetting and dispersing agent and defoamer in turn while stirring, stir and mix evenly to obtain the finished product of the present invention.

[0020] Wherein, the dosage form of the cotton defoliant prepared by the method is a water suspension.

Embodiment 2

[0022] A cotton defoliant, weighed 100g of thiadizuron, 50g of pyriflurone, 50g of pyridoxuron, 200g of organic bentonite, 60g of wetting and dispersing agent, 30g of defoaming agent and 50g of deionized water.

[0023] Wherein, the defoamer is defoamer GPE50, and the wetting and dispersing agent is a mixture of polyethoxylated fatty alcohol and sodium lignosulfonate in equal amounts.

[0024] The preparation method of the cotton defoliation agent is to take deionized water and add it to thiadizuron for dilution, then add pyrimiazide and pirazole to obtain a mixed solution; grind organic bentonite until the particle size is ≤1mm, and add it to the above mixed solution In the process, stir evenly; finally, at a temperature of 44°C, add wetting and dispersing agent and defoamer in turn while stirring, and stir and mix evenly to obtain the finished product of the present invention.

[0025] Wherein, the dosage form of the cotton defoliant prepared by the method is a dispersible o...

Embodiment 3

[0027] A cotton defoliant, weighed 150g of thiadizuron, 100g of pyriflurone, 100g of pyridoxuron, 250g of organic bentonite, 80g of wetting and dispersing agent, 50g of defoaming agent and 100g of deionized water.

[0028] Among them, the antifoaming agent is a mixture of three equal amounts of polydimethylsiloxane, phenylethyl alcohol oleate and polyoxypropylene, and the wetting and dispersing agent is an equal amount of polyethoxylated fatty amine and alkyl sulfonate. mixture.

[0029] The preparation method of the cotton defoliation agent is to take deionized water and add it to thiadizuron for dilution, then add pyrimiazide and pirazole to obtain a mixed solution; grind organic bentonite until the particle size is ≤1mm, and add it to the above mixed solution In the process, stir evenly; finally, at a temperature of 45°C, add wetting and dispersing agent and defoamer sequentially while stirring, and stir and mix evenly to obtain the finished product of the present invention...

Abstract

The invention discloses a cotton defoliant and a preparation method thereof. The cotton defoliant is prepared from the following components in parts by weight: 5-25 parts of thidiazuron, 2-20 parts of pyrithiobac-sodium, 1-20 parts of forchlorfenuron, 10-40 parts of organic bentonite, 3-15 parts of a wetting dispersant, 1-10 parts of an antifoaming agent and 2-20 parts of deionized water. The preparation method comprises the steps of firstly adding taken deionized water to thidiazuron for diluting; adding pyrithiobac-sodium and forchlorfenuron and then adding organic bentonite to a mixed liquid; and finally sequentially adding the wetting dispersant and the antifoaming agent while stirring at a specific temperature, stirring and mixing evenly to obtain a finished product. The cotton defoliant is wide in raw material source, low in cost and simple in preparation, pollution of leaves to machine-harvested cotton can be reduced, the mechanical cotton-picking operation quality and efficiency are improved, the leaves fall off in a dark green state, growth of a cotton fiber can be promoted and the target of yield increase is achieved.

Description

technical field [0001] The invention relates to the field of crop planting and production, in particular to a cotton defoliant and a preparation method thereof. Background technique [0002] Cotton is the main economic crop in my country, and its planting area ranks among the top in the world. Affected by many factors such as planting conditions, management measures, and cotton characteristics, mechanized harvesting has not been realized. Wheat, corn, beans, etc. have been harvested mechanically, but cotton is still harvested manually in large areas, which seriously restricts the cost and economic benefits of cotton planting, and the harvesting mode needs to be improved urgently. The main way to solve at present is to cultivate fine varieties and popularize defoliation technology and mechanical harvesting. Defoliation technology and mechanical harvesting have been gradually promoted in Xinjiang, my country in recent years. The "Twelfth Five-Year Plan" plans to implement me...
