| 摘 要： | 在新疆生态条件下,采用海岛棉新海35号研究同等用量3种施磷方式(犁地前全部撒施、犁地前撒施50%与作种肥施50%和全部作种肥施)对棉花农艺性状及产量的影响。结果表明:施磷方式对棉花生育进程的影响较小,各处理对新海35号棉花的农艺性状没有显著性的影响,P1处理可略为提高棉花花铃期叶面积指数,其中P1处理会略提高棉花后期的干物质积累量,以P1、P2处理的方式施磷肥,棉花的单株结铃数可提高4%~7%皮棉产量可提高12%~14.8%。

| Abstract: | Under the ecological conditions of Xinjiang,the effects of three phosphorus application methods(all before ploughing,50%before ploughing,50%for sowing and all for sowing)on agronomic characters and yield of cotton were studied by Island cotton Xinhai 35.Results show that the low phosphorus treatment have less effect on the cotton growing process,the processing of Xinhai 35 agronomic traits without significant influence.P1 treatment can slightly improve the cotton leaf area index during the blooming period,and P1 processing will slightly improve the late cotton dry matter accumulation.With the treatment of P1 and P2,the boll number per plant could increase by 4%~7%and the yield of lint could increase by 12%~14.8%. |
