摘要
通过用艾氟迪(AFD)600ml/hm2在棉花的初花期和盛花期喷施棉株中部的主茎、分枝和叶背,分析其对棉花生长发育和品质的影响,以研究鄱阳湖棉区中等肥力条件下AFD的施用时期。试验结果表明:在棉花的初花期和盛花期喷施艾氟迪(AFD)600ml/hm2均能有效协调棉花营养生长与生殖生长的关系,能够促进花芽分化、减少赘芽,增加单株果节数、促使棉花成铃集中并能改善棉花纤维品质,但略使衣分降低。
This research analysed the impact of AFD on cotton growth , development and quality, by spraying the 600 ml/hm2 concentration of AFD on stem, branch and notopedium in early flowering period and full flowering period. The aim is to study the best concentration and time of AFD application under the conditions of high water and fertilizer. The results indicated that spraying 600 ml/hm2 concentration of AFI） in early flowering period and full flowering period couldharmonize the relationship of vegetative growth and reproductive growth of cotton, it also eould accelerate differentiation of flower bud, reduce excess bud, increase the number of fruit node on individual plant, promote the concentrate of cotton bolls and improve cotton fiber quality. However, it would have a certain negative influence on ginningoutturn.
