Abstract

The invention relates to a method for chemically regulating and controlling cotton root configuration, comprising the following steps: firstly spraying mepiquat chloride after establishing seedling in the cotton seedling stage; secondly spraying the mepiquat chloride during the trefoil stage; spraying the mepiquat chloride in the five-leaf stage; spraying the mepiquat chloride for one time every 5-10 days during the period from the five-leaf stage to the top-cutting stage; and spraying the mepiquat chloride after cutting the top for twice. The invention adopts the action theory of the plant growth adjusting agent of the mepiquat chloride to implement the method for chemically regulating and controlling cotton root configuration by matching with the growth stage indexes of the cotton.

Description

technical field

[0001] The invention relates to a method for chemically regulating the configuration of cotton roots. Background technique

[0002] Cotton root system is the main organ for cotton water and nutrient absorption, and the development and spatial configuration of the root system have a significant impact on cotton yield. Xinjiang's cotton high-yield cultivation technology has been at the world's advanced level in recent years, and the cotton yield per unit area is far higher than the world's average per unit area yield, which is at the highest level in the world. However, there are also problems such as premature aging and hollowing of cotton in Xinjiang cotton area. The root sampling results showed that shallow root distribution and root water and nutrient absorption obstacles caused by premature senescence in the later stage were important reasons for a series of problems such as premature senescence and hollowing. The method of directional regulation of cott...
