缩节安是一种生长抑制剂,用在棉花上,具有抑制疯长、减少棉铃脱落、提高棉花产量的作用。今年将缩节安用于柑桔,目的是抑制夏梢的过量萌发与徒长,适当控制树体的营养生长,以保证生殖生长的正常进行,提高植株座果率、增加产量。试材为7年生枳砧锦橙,供试树20株;处理是用50ppm、70ppm、100ppm三个不同浓度的溶液喷雾树冠;五次重复、单株小区。试验处理于1984年6月12日进行。8月10日记载夏梢的生长量和抽发数,最后于果实采收前统计稳果情况。
Dian An is a growth inhibitor, used on cotton, with inhibition of insane, reduce cotton boll off, improve cotton yield role. This year will be reduced for the citrus citrus, the purpose is to inhibit the summer sprout excessive germination and leggy, proper control of vegetative growth of trees in order to ensure the normal reproductive growth, increase the rate of fruit set and increase production. The test materials were 7-year-old Poncirus trifoliata orange and 20 test trees. The treatment consisted of spraying crown with three different concentrations of 50ppm, 70ppm and 100ppm, five replicates and single plant plot. The test was conducted on June 12, 1984. August 10 recorded the growth of summer shoots and the number of pumping, the final statistics in the fruit before harvest stability situation.
