【摘要】 对不同浓度的乙烯利及不同使用次数在绿岛3号黄瓜上的应用进行了研究,结果表明:用80～100 mg/kg的乙烯利处理黄瓜幼苗2次(二叶一芯和三叶一芯),可有效地提高早期产量和总产量,改善品质,植株生长势较好,应用效果最好,适合在绿岛3号黄瓜冬春茬日光温室生产中推广应用。乙烯利浓度过高或使用次数过多会导致植株生长受抑,雌花率低,瓜条变短,前期产量和总产量都有降低趋势。更多还原

【Abstract】 Effect of different concentration ethephon and applying times on cucumber Lüdao No.3 was studied.The results showed that using 80～100 mg/kg ethephon two times on cucumber Lüdao No.3 at the stage of two-leaf and three-leaf seedling could raise its early yield and total yield,and could improve growth and fruit quality,which indicates that this method can be applied in Lüdao No.3 greenhouse in spring crop.High concentration ethephon or more application times would weaken plant growth,reduce female flower rate,shorten fruit length,and decrease early and total yield.更多还原
