| 摘 要： | 以陆地棉新陆早１号为材料，研究了缩节胺在宁夏灌区的应用效果，结果表明，ＤＰＣ在喷施后７￣３０ｄ内可提高棉叶的叶绿素含量和光合速率，改善群体结构，提早开花结铃，增加早期铃数，提高霜前花率和皮棉产量。以蕾期、花期喷施效果最好。

| Abstract: | DPC(N, N-dimthyl piperidinium chloride) applying effect on upland cotton (G.hirsutum L.) planted in Ningxia irrigated area was studied.Results showed that DPC could promote the increase of total chlorophyll content in the cotton leaf, especially for chlorophylla and bin 7 to 30 days after spraying.The application of DPC could increase the photosynthetic rate of leaves, regulate structure of the cotton plants, promote early flowering and boll setting, increase the number of early boll and the percentage of cotton harvested before frosting and cotton yield.The best effect resulted from twice of spraying in square appearing and flowering period. |
