摘要
通过棉花花铃期用不同DPC（缩节胺）剂量化控对株型和空间成铃分布的影响效应进行分析，表明，花铃期重控极端地抑制棉株营养体生长，使果枝数减少9．65－28．95％，总果节数减少12．04－28．42％，由于冠层密集，叶片变小，内围铃脱落严重，较CK多34．9－38．0％，且熟期延迟，产量降低，较适控减少10．8─12．0％。
The effect of DPC (Suo Jie An), sprayed indifferent concentrations , on plant type and ball distribution were examined in this study. The results showed that the heavy dose of DPC extremily restrained vegetative body, reduced the fruit shoots of 9. 65 - 28. 95 % and the fruit nodes of 12. 04 - 28. 42 %,densified the canopy, increased the dropping of inside boll of 34. 9- 38. 0%,delayed the maturity day,and thus made the yield decreased by 10. 8- 1 2. 0 %.
