摘要
在甘蔗的分蘖初期用不同浓度的乙烯利处理，结果表明：５０ｍｇ／Ｌ，１００ｍｇ／Ｌ浓度的乙烯利处理明显促进了甘蔗前中期的生长，改善了甘蔗的经济性状，使蔗茎的节间长度、茎长、茎径、单茎重及有效茎数均有所提高，获得显著的增产效果，并且明显提高了甘蔗的蔗糖分及品质．
The treatments of spraying different concentrations of ethephon were done at early tillering-stage of sugarcane. The results showed that the treatment with the concentrations of 50 mg/L and 100 mg/L of ethephon promote the growth of sugarcane during early and middle growth stages, and the internode length, stalk diameter, weights per stalk and millable stalks are increased, and obtained significantly higher cane yield. The treatments with the concentrations of 50 mg/L and 100 mg/L of ethephon also increased sucrose content in stalks and improved quality of juice.
