Abstract

The invention discloses a high-yield and high-quality early-maturing cotton cultivation method, which comprises the following steps: (1) selection of direct-broadcast cotton varieties with limited fruit branch types in the Yangtze River Basin; (2) mechanized sowing technology; (3) one-time balanced fertilization technology; (4) ) UAV prevention and control technology; (5) Whole-process chemical control technology. In step (2), after the previous crops are harvested, the stubble is promptly removed to level the land, and the cottonseed is develored and coated before sowing to control the seeding rate; the seed germination rate is more than 90%, and 1-2 grains are sown each time, and the row spacing The plant spacing is 55-65cm, the plant spacing is 15-20cm, the total seeding rate is 1.3-17,000 grains / mu, and the density is 7300-7700 plants / mu, so as to achieve the effect of no need for thinning after sowing full seedlings. The method of the invention promotes the growth of cotton plants, reduces labor and labor intensity, and increases 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...
