Defoliating and yield-promoting agent and preparation method and application thereof

Abstract

The invention discloses a defoliating and yield-promoting agent which comprises the active ingredients, namely thidiazuron and potassium chlorate. The defoliating and yield-promoting agent further comprises a solid penetrant and a sold dispersing aid. The defoliating and yield-promoting agent is applied in the cotton harvest time and can be used for effectively controlling the defoliation of cotton leaves, prolonging the reproductive stage of cotton and improving the cotton quality. The added solid penetrating agent and the added solid dispersing are more beneficial to absorption of cotton plants. The defoliating and yield-promoting agent is longer in pesticide effect duration time, enables nutritional ingredients of the leaves at a dark green state to be rapidly transferred to cotton rolls of the cotton plants to ensure that the cotton plants cannot wither and has the advantages of thoroughly solving the marcescence problem, reducing the pollution of the leaves on machine-harvested cotton, improving the quality and efficiency of mechanical cotton picking operation, promoting synthesis of fiber of cotton, increasing the cotton boll weight and reducing the cotton boll drop-out rate.

Description

technical field [0001] The invention relates to the field of crop planting and production, in particular to a defoliation and yield-increasing agent as well as its preparation method and application. 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. 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-...

Problems solved by technology

These products have the function of defoliation, but they are used in large quantities, high in cost, long in action, low in defoliation rate, and have a great impact on cotton quality.
