摘    要:通过不同氮素及缩节铵运筹对棉花的源库影响的研究表明 :增施桃肥和增加化控能促进叶面积变化合理 ,后期下降缓慢 ,光合强度提高。在库上表现为单株果节数增多 ,成铃强度提高 ,叶铃比下降。在高肥力条件下 ,增强化控更能增加铃数 ,提高产量

关 键 词:棉花  氮肥运筹  源库质量

Abstract:The experiment was designed to study the effects on the quality of source sink in cotton, the result showed that the increase of the peach fertilizer and chemical (DPC) could adjust the grow of leaf area, LAI maintained at optimum range and decreased slowly in ripen period, the photosynthetic intensity of leaf raised. The number of fruit node got increased, the intensity of retained boll raised, the leaves/bolls decreased. The DPC could increased the number of retained bolls and yield at high soil fertilizer.
Keywords:cotton  application of nitrogen fertilizer  quality of source  sink
