摘要: 采用种植密度和施肥量两因素三水平研究了其对冈棉10号产量的影响。结果显示,种植密度和施氮量及其互作对冈棉10号产量的影响均极显著,最适宜的栽培模式为种植密度33 000株/hm2、施氮量225 kg/hm2,该条件下皮棉产量最高。

Abstract: To study effects of different planting densities and nitrogen application rates on yield of cotton variety Gangmian No.10,the factors of nitrogen application rates and planting density were designed with three levels in this experiment.The results showed that nitrogen application rates,planting density and their interactions had highly significant effects on the yield of Gangmian No.10.When the density was 33 000 plants/hm2 and nitrogen application rates was 225 kg/hm2,the yield was the highest.

Key words: cotton, Gangmian No.10, planting density, nitrogen application rates, yield
