“缩节安”又名“Pix”,化学名称为N.N一二甲基(口辰)啶鎓氯化物,是一种新型棉花生长调节剂。1982年经我们初步试验,获得了104亩棉田施药比不施药普遍增产20％以上的好效果。为进一步探讨“缩节安”对棉花的实用价值,1983年全县扩大示范,总面积达4,800余亩。根据1982年的试验资料,我们将棉花化控示范的最佳用药量定为每亩3—5克,即每亩60ppm—100ppm,施药时间定为7月1日—7月20日。在施药过程中,我们区别对待长势不同的棉苗,长势最好的每亩施5克;旺的每亩4克;
“Reduced security” also known as “Pix”, the chemical name is N. N a dimethyl (cinnabar) pyridinium chloride, is a new type of cotton growth regulator. In 1982, after our preliminary test, we obtained the good effect of applying more than 20% of the total yield of 104 mu of cotton field compared with no spraying. In order to further explore the practical value of shrinking the security on cotton, the county expanded its demonstration in 1983 with a total area of 4,800 mu. According to the test data of 1982, we set the optimal dose of cotton chemical control demonstration at 3-5 grams per mu, that is, 60ppm-100ppm per acre. The pesticide application time is from July 1 to July 20. In the spraying process, we distinguish between different growing cotton seedlings, the best growing 5 grams per acre; Wang 4 grams per acre;
