Abstract

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
