摘　　要：应用新型保铃剂进行了防治棉花烂铃的效果试验。结果表明,在棉花生长盛期,用新型保铃剂进行多次叶面喷施,结合科学栽培管理措施,可以起到防治烂铃、增加产量的效果,与不用保铃剂的处理相比,烂铃减少13%,产量增加16%;在每公顷密度15 000株、氮肥用量450 kg的情况下,配合喷施新型保铃剂的互作效应最好,烂铃最多减少42%,产量最多增加17%。This experiment was about the effect of the new mixed agent to prevent the boll-rot of cotton that was carried out on the Yangtze University in 2004.The result showed that the new mixed agent developed by plant disease laboratory of Yangtze University could prevent boll-rot of cotton and increase the yield of cotton. The treatment of using the agent could decrease the boll-rot 13% and increase the yield 16% than CK. The multi-factors test also showed that the new mixed agent combining the reasonable cultivation measure was more advantageous to its effect. With the density of 15000 plants each hectare and the nitrogen fertilizer of 450 kg each hectare,the effect of the new mixed agent to prevent boll-rot of cotton is the best.
