棉花使用健壮素有增产效果,但使用不当,反而会干扰棉花正常生育。本文将着重讨论棉花使用健壮素对棉铃生长、蕾铃脱落、品质和产量等方面所引起的变化,以期明确该剂在本地区的应用价值和合理的使用技术。田间试验在青浦县环城、朱家角,嘉定县徐行,宝山县罗店,上海县七一等公社进行,喷药一般在见花至开花期,每亩纯药2～5克(多数田块2～3克),大多数试验田用药一次。少数田块用药二次,半数以上试验田设3～4次重复,余者为简单的对比试验。试验结果一、棉铃生长定期测量棉铃的直径(铃龄3、5、7、10、20、30天),下部棉铃直径,各次测量结果,健壮素处理的均大于对照1.0～3.7%。
The use of a healthy cotton yield increase effect, but improper use, but will interfere with normal cotton production. This article will focus on the use of healthy cotton on cotton boll growth, buds off, quality and yield changes caused by changes in order to clear the agent in the region of the value and rational use of technology. Field trials were carried out in Qingpu County Ring, Zhujiajiao, Xuhang in Jiading County, Luodian in Baoshan County and Qili Commune in Shanghai County. The spraying was generally carried out at flowering and flowering stages, with 2 to 5 grams of pure drug per acre (most plots 2 ~ 3 grams), most experimental field medication once. A small number of field medication twice, more than half of the experimental field set 3 to 4 times repeated, the remaining for a simple comparison test. Test results First, the growth of bolls Regular measurement of boll diameter (bell age 3,5,7,10,20,30 days), the lower part of the boll diameter, the measurement results, the healthy hormone treatment were greater than the control 1.0 ~ 3.7%.
