缩节胺在新疆特早熟棉区已成为常规技术,但在使用时间、施用方法上的最佳用量未见专题报导。为此我们从1989年-1996年8年间对缩节胺,采用千分之 0.3,0.4,0.5进行拌种;从中筛选出 0.5,即 666.7m2用 4克缩节胺(按种子重量)拌种,又分别在棉花蕾、花铃期进行不同剂量的调控,以矮壮素(按种子重量)每666.7m2用8克拌种为对照,以等量清水为空白对照。试验结果:棉铃提早5—7天吐絮,单铃重增重0.3—0.5克,霜前花提高 9.5—17.4%,亩净增值增加 30—206.55元,投产比为1:2.14─1:11.56。
Polyamines in Xinjiang precocious cotton area has become a routine technology, but the use of time, the best method of application no special reports. To this end, we from 1989 to 1996, 8 years on the shrink amines, using 0.3 0.3,0.4,0.5 seed dressing; selected from 0.5, that is 666.7m2 with 4 grams shrink Day amine (seed weight) seed dressing, respectively, in the buds of cotton, flower and boll stage for different doses of regulation to CCC (per seed weight) per 666.7m2 with 8 grams of dressing as a control, with the same amount of water Blank control. Test results: Boll boll 5-7 days earlier, single boll weight gain 0.3-0.5 grams, 9.5-17.4% before the frost rose, mu net added value increased 30-206.55 yuan, put into operation The ratio is 1: 2.14─1: 11.56.
