正三十烷醇CH_3(CH_2)_(28) CH_2OH,是美国密执安州大学S.K.Ries教授1975年从紫苜蓿中发现的,以后经国内外研究,也可以从蜂蜡、糠蜡,甚至蔗蜡中提取,是一种新型农用激素。其特点是:用量少,国外报导最适使用浓度只有0.01～0.1毫克/升;效果显著,国外报导对不同农作物可增产10～40%;毒性小,无公害。因此,正三十烷醇应用于农业,已引起国内外的重 N-triacontanol CH_3 (CH_2) _ (28) CH_2OH, is the University of Michigan State Professor SKRies from purple alfalfa found in 1975, after the study at home and abroad, but also from beeswax, bran wax, and even cane Wax extraction, is a new type of agricultural hormones.
