乙烯利在中农8号黄瓜上的应用效果

对不同浓度的乙烯利及不同的施用次数在中农８号黄瓜上的应用进行了研究。结果表明，用１００μＬ·Ｌ－１的乙烯利处理黄瓜幼苗１次或２次，能够有效地提高前期产量，同时，对植株的生长和瓜条的商品性没有太大的不良影响，适合在生产中推广使用。乙烯利浓度过高或施用次数过多会导致空节的形成，从而使雌花率降低，雌花开始节位升高，始花期推迟，前期产量和总产量都有降低趋势，且对瓜条商品性也有不利的影响。

Ethylene Application on Cucumber Zhongnong No.8

Effect of different ethylene concentrations and applying times on cucumber Zhongnong No.8 was studied. The results indicated that using 100 LL-1 ethylene one or two times on Zhongnong No.8 could raise its early yield efficiently without bad effect on plant growth and fruits. High concentrations or more application times would lead to empty nodes,low female flower rate,high first female flower node and late blooming date,which were harmful to both early and total yield as well as to fruits.
