| 摘 要： | 研究了新疆特早熟棉区化学调控对棉花群体发育的影响。结果表明：在肥水适量的基础上，运用ＤＰＣ对棉花群体进行系统地化学调控，能够有效合理的协调营养生长和生殖生长的关系，加快生殖器官干物质的积累进程，使群体叶面积的高峰期提前，并将叶面积指数（ＬＡＩ）稳定在适宜范围，改善了冠层光照条件，使棉花成熟期提前，霜前花产量提高。

| Abstract: | This report studied the effect of DPC on populatoin development of cotton under suitable fertility and water codintions in special early cropping cotton areas of XinJiang. The results showed as follows: systematic chemical regulation Of DPC 1)accelerated the process of dry matter accumulation of reproductive organ, 2)Improved the relation of vegetative and reproductive growth, 3)Moved up the peak value of leaf area index (LAI) And maintained it optimum range. 4)Improved light distribution of canopy 5)Raised the yield before frost. |
