Abstract:A field experiment was carried out in order to explore the influence of 2 fertilization modes (F1, NPK fertilizer all dropped; F2, N fertilizer dropped and PK fertilizer as base fertilizer), 4 N application rates (at 150, 225, 300, 375 kg/hm2, respectively) on the yield, quality, water use efficiency(WUE) and nitrogen use efficiency (NUE) of mulched-cotton by drip irrigation. The results showed that the boll retention rate increased significantly, and the number of available bolls per plant and single boll weight decreased, cotton yield, WUE, NUE decreased when N application rate was 150 kg/hm2 under the two fertilization modes. Shedding rate of cotton decreased at first and then increased while yield and WUE and NUE increased first then decreased with nitrogen supplying increased under 4 nitrogen application rates. The average cotton boll retention rate of F2reduced by 335% compared to F1, the average yield of F2 increased by 406% compared to F1, and WUE and NUE of F2 increased by 1258% and 301% compared to F1. Nitrogen amount had a significant influence on uniformity index, micronaire value, and the breaking tenacity of cotton fiber, and nitrogen rate was 300 kg/hm2, the above-mentioned index of cotton fiber reached maximum. Cotton has low boll retention rate and high available bolls and single boll weight and lint percentage under F2 mode with nitrogen amount at 300 kg/hm2, yield reach 699233 kg/hm2, WUE and NUE come to 145 kg/m3 and 459% respectively, cotton fiber has good maturity and high strength.
