【摘要】 以“津春4号”黄瓜为材料,通过采用不同浓度的乙烯利在黄瓜不同叶龄期进行不同次数喷施试验,研究了乙烯利对黄瓜产量及主要农艺性状的影响。结果表明:用100μl/L的乙烯利在1叶或2叶龄期处理1次能有效提高雌花率及产量,特别是前期产量,且瓜条品质有所提高;不同浓度的乙烯利处理后黄瓜株高变矮,节间变短,空节率增高,而雌始节、雌花率和被影响的节数则表现为增加趋势。更多还原

【Abstract】 Cucumbers of "Jing Chun No.4" were sprayed with ethrelat in different rates,different dates and different times to study the yield and the main agronomic characters.The results showed that the treatment with the concentrations of 100 μL/L ethephon at different conc entrations in one-leaf and two-leaf period by one time could efficiently increase female flower node ratio and yield,especially the prophase yield,and had no effect of aberration.The internode length and plant height were shortened;node ratio without flower,the female node,the female flower ratio and the number of affected node was reduced after the cucumber were sprayed with ethrelat.更多还原
