三十烷醇是一种天然的生长调节剂,和其它植物生长调节剂相比,它有自己的特点:①广谱性。在植物2—3叶真叶期施用能不同程度地提高黄瓜、玉米、大豆、胡萝卜、水稻、西红柿、小麦、菜豆等的产量。②对植物代谢有多方面影响。如增加千重、叶面积、还原糖浓度、自由氨基酸、可溶性蛋白氮以及还原氮的水平,促进蛋白质的合成率。③发生作用快。施用后几分钟到几十分钟内就可显效。④用量小。0.1—1微克/升即可稳定增加玉米和水稻干重,对环境没有污染。 但应用中存在的问题是效果不稳定,可靠性差,田间试验与温室试验有很大差距,有时甚至全无效果。其原因系由于其效应易受许多生物学和物理学因素的影响。如喷药 Triacontanol is a natural growth regulator that has its own characteristics compared to other plant growth regulators: ① broad spectrum. The application of 2-3 leaves of true leaf in the plant can increase the yield of cucumber, corn, soybean, carrot, rice, tomato, wheat, kidney bean and so on to some extent. ② on plant metabolism in many ways. Such as increasing the weight, leaf area, reducing sugar concentration, free amino acids, soluble protein nitrogen and reducing nitrogen levels, and promote protein synthesis rate. ③ occurs quickly. A few minutes after application to dozens of minutes can be effective. ④ small dosage. 0.1-1 micrograms / liter can be a steady increase in dry weight of corn and rice, no pollution to the environment. However, there are problems in the application of instability, poor reliability, field trials and greenhouse tests have a big gap, and sometimes no effect. The reason is due to its effects susceptible to many biological and physical factors. Such as spraying
