Equal rowledge ultrawide film-film three-row simplified cultivation method for mechanical picking of hybrid cotton

Abstract

The invention discloses an equal rowledge ultrawide film-film three-row simplified cultivation method for mechanical picking of hybrid cotton. The method comprises the following management steps of (1) preparation before sowing; (2) sowing: precisely sowing seeds by adopting ultrawide films according to a rowledge of 76cm, wherein a mulching film is 2.05m wide, one seed is sowed into one pit, one film covers three rows and three bands, one pipe covers one row, a planting distant is 9.5cm, water is fed within 24 hours after the seed is sowed, and the water amount is 8-15m<3> per mu; (3) cotyledon period management: checking seedlings, supplementing seeds and performing a chemical regulation method; (4) seedling stage management: performing intertillage, chemical regulation and pest damage prevention and treatment; (5) bud stage management: performing intertillage, chemical regulation, water topping and pest damage prevention and treatment; (6) flower and boll stage management: performing chemical control, water fertilization, topping and pest damage prevention and treatment; (7) boll opening stage management: performing ripening defoliation and harvesting at proper time. According to the equal rowledge ultrawide film-film three-row simplified cultivation method for the mechanical picking hybrid cotton, the work for seedling fixing, topping and chemical control is reduced, and ripening of the hybrid cotton is promoted; compared with conventional high-density cotton, the mechanical picking hybrid cotton has the advantage that the yield is increased by 13.5 percent.

Description

technical field

[0001] The invention relates to a cotton cultivation method, in particular to a simplified cultivation method of machine-harvested hybrid cotton with equal-row-spaced super-wide film, one film and three rows. Background technique

[0002] With the continuous advancement of agricultural modernization, intensive, large-scale, and modern production levels have been gradually realized, and the level of agricultural machinery and equipment has also been continuously improved. Especially in recent years, with the continuous development of cotton mechanized picking technology and the comprehensive mechanization of agricultural production Has reached a higher level, mechanical harvesting has become an inevitable trend of cotton production, and it is also the only way.

[0003] The research on machine-picked cotton in foreign countries started very early. The United States started the development and research of cotton-picking machinery as early as the middle of the ...
