喷施保铃剂与杀虫剂种子处理技术配套使用对棉花生长发育及产量的影响

本研究表明，叶面喷施保铃剂与常规拌种剂（６０％甲拌磷乳油＋５０％林丹胶悬剂）配套使用，表现出显著的防虫壮苗、促进生长、保铃增产的正联合作用。较单一的种子处理果枝数分别增加１３．５％和１．４％；现蕾数增加５１％和１４％；单株成铃数提高２９．４％和１７．３％，产量提高２９．３％和３１．４％。较空白对照处理保铃增产效果更加显著

The Effect of Spraying Boll keeping Agent Combining Pesticide Seed Treatment on the Growth and Yield of Cotton

The study shows that the combined effect of spraying BKA with 60% phorate EC or with 50%.Lindane SC is significant and positive in controlling pest, keeping seedling, quickening growth, keeping boll and increasing yield of cotton. As compared with the single seed treatnment, the increasing rates of the number fruit branch are 13.5% and 1.4% respectively; that of the flower buds-51% and 14%; the bolls on a single plant-29.4% and 17.3;and the yield-29.4% and 31.4%.As compared with the check plot, the effect is even more signficant.
