| 摘 要： | 在膜下滴灌条件下 ,北疆棉花花铃期以灌水 2 2 5mm、随水根施氮肥 1 50 kg/hm2 处理的皮棉产量最高 ,群体冠层结构较为合理 ,过高或过低的水肥状况对棉株生长都不利。在花铃期 ,合理的群体冠层结构诊断指标应为 :叶面积指数 1 .56～ 3.95,叶倾角 36°～ 4 5°,太阳辐射自上而下逐渐递减 ,地面可见光斑 ,散射光透过率 0 .1 87～ 0 .2 6 3。

| Abstract: | The yield of ginned cotton is highest and the canopy structure is rational under the mulch drip irrigation in case of the treatment of W225N150 during the blooming period in North Xinjiang, the cotton growth was unfavorable with the treatment of higher of lower water and fertilizer.Diagnose standard of rational cotton canopy structure under MDI was as follows: LAI, TD and MLA were 1.56～3.95，0.234～0.357 and 36°～48° respectively during the period of blooming. |
