摘 要:通过春播、夏播对短季棉中棉16和中熟棉中棉12进行叶片发育特征研究发现,前者的主茎叶位发生率和果枝叶位发生率均较高,叶片叶龄结构的最佳期出现较早,但群体叶片衰老较早,单叶叶面积及单株叶面积均不及中棉12,因而生物量较小,春播的产量潜力也不及中棉12.但中棉16夏播可收获较多的霜前优质皮棉.Having studied on characteristics of leaf development of Zhongmian 16 (short-season cotton ) and Zhongmian 12 ( mid-muturity cotton) by two sowwing dates in 1988, We found that main stem and fruiting branch leaf mode production rates of Zhongmian 16 were higher than Zhongmian 12 and its best composition of population leaf age presented more early too, but its leaf population tended to senescence more early, its single leaf area and single plant leaf area were less, so that mass of Zhongmian 16 was smaller and its yield was lower than Zhongmian 12 in spring-sowwing treatment but pre-frost yield was higher in summer-sowwing treatment.
