乙烯利是一种植物生长调节剂,化学名称为2-氯乙基膦酸,酸性,淡棕色液体,可溶于水。我厂生产的乙烯利,经中国医学科学院卫生研究所进行毒性测定,证明对动物无明显积蓄毒性,对人体不致产生危害。乙烯利施用在作物上,能很快地被作物各器官吸收,并在茎、叶、花、果等组织内释放出乙烯,调节作物的代谢、生长和发育。它有打破种子休眠、减少顶端优势、去雄、催熟及增产等作用。例如,用于水果、番茄,可以促使成熟;用于果树疏果,可提高产量和质量;用于烟草,可提前落黄,提高烤烟质量;在作物苗期施用,可抑制作物生长而不致徒长倒伏,且能减少腋芽;苹果在花前施用,可以催花,并使花期集中;黄瓜在花前用药,可以多开雌花,增加产量;乙烯利还可用作棉花的脱叶剂;用于橡胶树,能促进胶乳增产。
Ethephon is a plant growth regulator known by the chemical name 2-chloroethylphosphonic acid, an acidic, light brown liquid that is soluble in water. The ethephon produced by our factory was tested for toxicity by the Institute of Health of Chinese Academy of Medical Sciences and proved no obvious accumulation of toxicity to animals and no harm to the human body. Ethephon is applied to crops and can be quickly absorbed by various organs of plants and release ethylene in tissues such as stem, leaf, flower and fruit to regulate the metabolism, growth and development of crops. It has the effect of breaking seed dormancy, reducing the top edge, removing male, ripening and increasing yield. For example, for fruit, tomato, can promote maturity; for fruit tree thinning, can improve yield and quality; for tobacco, yellowing can be ahead of schedule to improve the quality of flue-cured tobacco; Seedling stage of the crop can inhibit the growth of crops without lengthening Lodging, and can reduce the axillary buds; apple application in front of the flower can promote flower, and the flowering period; cucumber in the flower before treatment, you can open more female flowers, increase yield; ethephon also can be used as cotton defoliants; for Rubber tree, can promote latex production.
