Abstract:

In order to explore the suitable planting density and nitrogen rate of direct seeding cotton in summer under the measures of increasing density, reducing nitrogen and simplifying fertilization (One-time fertilization at first flowering), split plot design trail was conducted to explore the effects of planting density (75 000 and 90 000 plant/ha), nitrogen rate (135, 195 and 255kg/ha) and their interaction on agronomic traits, yield and fiber quality in three major cotton production areas of Hubei province in 2016 and 2017. The results showed that when the planting density was increased from 75 000 to 90 000 plant/ha, the length of middle-top fruiting branches decreased by 1.3 and 1.8cm respectively, the length of first fruit internode of fruiting branch decreased by 0.5 and 0.6cm respectively in two years; the number of bolls per unit area increased by 90 000 plant/ha; but there was no significant difference in agronomic traits, harvest lint yield and fiber quality. There was also no significant difference in theoretical lint yield, harvest lint yield, fiber quality and agronomic traits across nitrogen fertilizer from 135kg/ha to 255kg/ha. Under the pattern of the cotton direct seeding in summer with simplified fertilization, cotton could achieve a relatively stable yield within the range of high density and low nitrogen fertilizer set up in this study. When this planting pattern was implemented in the main cotton producing areas of Hubei province, the density can be increased to 90 000 plant/ha and the nitrogen fertilizer reduced to 135kg/ha.

Key words: Cotton, Direct seeding in summer, Yield, Quality, Planting density, Nitrogen
