摘　　要：采用无土栽培基质穴盘育苗法,对不同浓度保水剂对黄瓜幼苗生长的影响进行了研究。结果表明:保水剂可以增加基质含水量,除0.1%处理外,都抑制出苗,适宜浓度可以提高秧苗质量、根系活力和叶片含水量,浓度过大会抑制生长。综合分析得出以保水剂0.5%处理效果为好。The different concentrations of water-retaining agent on cucumber seedlings were studied by soilless culture. The results showed that the water-retaining agent could increase substrate moisture. All treatments decreased emergence rate but 0.1% treatment. Suitable concentration could improve seedling quality, root activity and leaf water content, but higher concentration treatments inhibited cucumber seedlings growth. By comprehensive analysis, 0.5% was the best treatment in this experiment.
