Ultrahigh yield cultivation method for cotton canopy design and application of ultrahigh yield cultivation method

Abstract

The invention discloses an ultrahigh yield cultivation method for the cotton canopy design and application of the ultrahigh yield cultivation method. The method includes the following steps of firstly, delaying topping, wherein the topping time of cotton is delayed for 4 days to 5 days; secondly, completely conducting capping and fertilizing, wherein capping and fertilizing are completed in ten days after topping is conducted; thirdly, appropriately conducting chemical control at the right moment, wherein chemical regulation and control are conducted twice after topping is conducted, chemical regulation and control are conducted for the first time 2 to 3 days after topping is conducted, and chemical regulation and control are conducted for the second time 5 days to 7 days after chemical regulation and control are conducted for the first time; fourthly, prolonging insect control time, wherein the insect control time is prolonged to 20 days to 25 days. By taking comprehensive measures of appropriately delaying the topping time, completely conducting capping and fertilizing, appropriately conducting chemical control at the right moment, delaying the insect control ending time and the like, and by fully using the characteristic that temperature and photothermal resources on the top of cotton are rich, the yield-increasing potential of cotton is tapped, and the per unit area yield of cotton is increased by more than 15% compared with an existing cultivation method.

Description

technical field [0001] The invention relates to the technical field of cotton cultivation, and particularly discloses a super-high-yield cultivation method and application of cotton canopy design. Background technique [0002] Cotton yield is an economic trait that is affected by many factors. In addition to the direct effect of cultural technical measures, it is also affected by various non-technical factors such as national policies, regional economy, climate and soil. Due to differences in natural and economic conditions such as economy, climate, and soil, different regions have different technological approaches to high cotton yields. However, as far as a certain area is concerned, the high-yield cultivation methods adopted must be able to make full use of local natural resources such as temperature, light, water, and heat, adapt to the local economic development level, and have relatively stable and efficient production capacity. That is to say, in a certain natural ec...

Problems solved by technology

Due to the promotion of hybrid cotton, cotton farmers are overly superstitious about the heterosis of hybrid cotton, and the planting density is getting thinner. In addition, the supporting technology has not been able to keep up with it in time. The cotton production has not been improved due to the promotion of genetically modified hybrid cotton, and the cotton production has entered a stagnation stage.
