摘要:
棉花叶面积和干物质的形成均随主茎展叶数增加而增大。展12~16叶时,为主茎叶扩面高峰期;展16~24叶,为果枝叶扩面高峰期;棉株70%左右的生物产量在展16~24~4叶时形成,展24~24~4叶时是生物产量与经济产量形成的高峰期。“四桃”中伏桃与早秋桃为优质桃,其比率在70%~80%最佳。栽培中调节棉花生育展叶进程,在产量形成的重要时期施足花铃肥,根据棉花叶面积增大规律看叶“化控”,以协调个体生育与群体发展之矛盾,塑造高光效株型,建立良好的群体生态结构,确保高产、优质。
Abstract:
Results showed that the rapid enhancement period of leaf area of the main stem and fruiting branch were appeared, respectively, during the expanding of 12th to the 16th leaf and the 16th to the 24th leaf of the main stem. 70% of bimass was produced from the 16th of the main stem to the 24~4th leaf of the fruiting branch. The peak of bimass and economical yield were both formed from the 24th to the 24~4th leaf. 70%—80% of bolls was formed during the 22th to the 24~4th leaf. It was the best boll setting pattern for cotton production. These results indicated that the following measures would be favourable to good quality and high yield of cotton: regulating the planting date and leaf expanded process of the main stem; spraying a growth retardant upon cotton plants before the peak of leaf area and applying a heavyly blooming fertilizer after the 16th leaf.
