[目的]探讨不同播期和密度处理对超短季棉品种个体发育动态的影响,明晰它们对棉花营养生长和生殖生长的效应,为黄河流域冀东棉区棉花种植的播期和密度管理提供理论和实践指导.[方法]以超短季抗虫棉546系为材料,探讨了不同播期(播期Ⅰ:5月20日,播期Ⅱ:6月2日,播期Ⅲ:6月14日)和密度(低密度:12万株/hm2,中密度:15万株/hm2,高密度:18万株/hm2,)处理对其个体生长发育动态的影响.[结果]不同的播期和密度处理对超短季棉546系的个体生长发育具有明显的影响,其中播期的影响效力要高于密度的影响效力,而播期对于棉株个体果枝数量发育的影响效力又明显高于对主茎伸长生长和加粗生长的影响效力.[结论]在黄河流域的冀中棉区对超短季棉546系栽培过程中,可以通过播期和密度的调控,有效地促进其营养生长和生殖生长,夯实其产量基础.

[Objective]The paper was to explore the effect of different sowing dates and densities individual morphological development of super short-season insect-resistant cotton, confirm their effects on vegetative and reproductive growth of cotton, so as to provide theoretical and practical guidance for sowing date and density management of cotton planting in Jidong cotton growing region in Yellow River Basin.[Method]With super short-season insect-resistant cotton "546" as materials, the effects of different sowing dates(sowing date Ⅰ: May 20;sowing date Ⅱ: June 2;sowing date Ⅲ:June 14)and densities(low density:120000 planls/hm2;middle density:150000 plants/hm2;high density:180000plants/hm2)on individual morphological development of super short-season insect-resistant cotton were explored.[Result]Different sowing dates and density treatments significantly affected the individual morphological development of super short-season insect-resistant cotton "546".The effectiveness of sowing date was higher than the effectiveness of density, and the effectiveness of sowing date on development of number of individual fruit branches was higher than that on plant height and stem diameter.[Conclusion]The regulation of sowing date and density during the cultivation process of super short-season insect-resistant cotton"546"in Jidong cotton growing region in Yellow River Basin could effectively promote vegetative and reproductive growth of cotton, strengthening its production base.
