乙烯利也叫“一试灵”,是一种对植物有广泛生理活性的生长调节剂,用于棉花,其催熟功能显著。适时适量喷施乙烯利,可使棉花吐絮提早7—10天,霜前花增加一至三成,增产5—15％。使用乙烯利要求严格,技术性强,为了提高催熟效果,应注意以下七点。 l.安全。乙烯利虽系低毒制剂,对人畜微毒,但原液对皮肤、眼睛等具有刺激作用,故配制时要防止溅落在皮肤上。 2.使用对象。地肥后劲足,秋桃多的迟吐絮棉,最宜使用。喷乙烯利可加速棉铃吐絮,减少霜
Ethephin, also known as “Triton,” is a growth regulator that has a wide range of physiological activities on plants and is used in cotton, where its ripening function is significant. Appropriate amount of ethephon sprayed, cotton boll can be made earlier 7-10 days, frost before the flowers increased by 1 to 30%, an increase of 5-15%. The use of ethylene Lee demanding, strong technical, in order to enhance the ripening effect, should pay attention to the following seven points. l. Safety. Although the low-toxicity ethephon formulations, micro-toxic to humans and animals, but the liquid on the skin, eyes and other stimulating effect, it is formulated to prevent splashing on the skin. 2. Use the object. Fat enough stamina, autumn peach flocculus, the most appropriate to use. Spraying ethephon can speed cotton boll and reduce frost
