Cotton planting method reform should be combined with autumn sowing production
In recent years, to promote high cotton yields, the Ministry of Agriculture of the People's Republic of China has carried out a 10,000-mu high-yield cotton creation activity in the major cotton-producing provinces nationwide. Recently I inspected high-yield cotton fields in Hubei, Anhui, Jiangsu, Jiangxi and other provinces, and previously also conducted surveys in high-yield cotton fields in Hunan and Zhejiang provinces. The high-yield cotton creation goals are broadly the same across regions, but the planting patterns are not entirely the same, and the planting methods each have their own particularities. Cotton yield is composed of indicators such as planting density, number of bolls per plant, boll weight and lint percentage, among which planting density is closely related to cotton yield, and planting density

Cotton struggling to open its bolls? Reforming the planting method is key
In recent years, with the continuous deepening of the breeding of new cotton varieties and the improvement of sowing and seedling-raising methods, as well as the increase in the degree of agricultural mechanization, the planting method of cotton fields has become extremely important for high cotton yields. In the era when conventional cotton varieties dominated, cotton sowing was mostly direct seeding, cotton planting density was relatively high, cotton row spacing was relatively small, and cotton fertilization was mostly broadcast application. After hybrid cotton was promoted and applied on a large scale, because the individual development of hybrid cotton is larger, cotton field density was continuously reduced, cotton row spacing was expanded, and cotton
