Abstract

The present invention discloses a cultivation method of high-yield, high-quality and early-maturing cotton. The cultivation method of the high-yield, high-quality and early-maturing cotton comprises the following steps: (1) selection of limited fruit branch-type direct-sowing cotton varieties in Yangtze river basin; (2) a mechanized sowing technology; (3) a one-time balanced fertilization technology; (4) an unmanned aerial vehicle prevention and control technology; and (5) a whole-process chemical regulation and control technology. In the step (2), after previous crops are harvested, stubble cleaning and land leveling are carried out, before sowing, cotton seeds are delinted and coated, and the sowing amount is controlled; a seed germination rate is 90% or more, one sowing is conducted 1-2grains every time, row spacing is 55-65 cm, plant spacing is 15-20 cm, the total sowing amount is 13-17 thousand grains/mu, density is 7,300-7,700 plant/mu and an effect of not needing thinning afterone sowing of full seedling is reached. The used method promotes growth of cotton plants, reduces manual and labor intensity and improves cotton yield.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a cultivation method for high-yield and high-quality early-maturing cotton. Background technique [0002] my country has a large population and little land, and the pressure on food production is huge. The contradiction between grain and cotton competition for land is prominent. A consensus has been reached on the development trend of cotton not competing with grain. As early as the early 1970s, Chinese cotton researchers and farmers began to look Early-maturing cotton varieties, such as Heishan Mian No. 1, Liao Xia No. 1, etc. [0003] Zhongmian No. 10, the first generation of early-maturing cotton variety in my country, is 8 days earlier than Heishan Mian No. 1, and its yield is 20% higher than that of the national summer cotton regional test control. It is the first to achieve double cropping of wheat and cotton in North China. Poor performance, incomplete supporting t...
