摘要: 为了探讨棉花(Gossypium spp.)高效综合栽培管理模式,以自育的棉花品种冈86为材料,研究了不同密度、施氮量和施肥模式对棉花产量和纤维品质的影响。结果显示,冈86在3.3万株/hm2、低氮水平180 kg/hm2和见花一次施肥的条件下增产,不同施氮量和施肥模式对冈86产量构成因素铃数、铃重和衣分没有显著影响,对冈86部分纤维品质有显著影响;不同施氮量对整齐度指数有显著影响;不同施肥模式对断裂比强度存在显著影响,一次见花施肥处理的断裂比强度显著高于常规施肥处理。

Abstract: In order to investigate the efficient comprehensive cultivation management model of cotton(Gossypium spp.), Gang 86 was used as material to study the impact of different planting density, nitrogen application and fertilization modes on yield and fiber quality. Results showed that the treatment of the planting density was 3.3×104 plants/hm2, 180 kg/hm2 fertilization level and one-time fertilization at the time of flowering had the highest cotton yield. The number of bells, boll weight and lint percentage were not significant under different treatments. Some fiber quality of Gang 86 were significant difference between different nitrogen application treatments. Uniformity index was significant difference between different nitrogen application, different fertilization modes had significant effects on the specific breaking strength, and the specific breaking strength of the one-time fertilization at the time of flowering treatment was significantly higher than that of the conventional fertilizer treatment.

Key words: cotton(Gossypium spp.), Gang 86, density, nitrogen application, fertilization modes, yield, fiber quality
