丰产素是黑龙江省绥化市参美化工厂研制的一种新型植物生长调节剂。为了探讨该丰产素对黑穗醋栗增产和抗病效果,我们于1987～1988年连续两年进行了试验。丰产素为瓶装100毫升,使用时,按每亩用药25毫升,兑水20公斤,配成800倍液。喷药前用少量25～30℃温水配成母液,快速搅拌至起大量泡沫为止,倒入喷雾器中,加水
High yield of Suihua City, Heilongjiang Province, the United States and the United States chemical plant developed a new plant growth regulator. In order to explore the high yield of black currant yield and disease resistance, we conducted in 1987 to 1988 for two consecutive years of trials. High yield of 100 ml bottled, when used, according to 25 ml per acre medication, watered 20 kg, dubbed 800 times solution. Spray before using a small amount of 25 ~ 30 ℃ warm water dubbed the mother liquor, stirring quickly until a lot of foam, into the sprayer, add water
