摘　　要：采用无土栽培基质穴盘育苗,研究不同浓度保水剂与不同供水方式对西葫芦幼苗生长的影响。研究结果表明,保水剂在一定范围内可促进西葫芦幼苗生长,提高秧苗质量和生理活性;底部供水明显地优于传统供水方式,减少了供水次数,并且降低了苗期的供水总量。保水剂浓度为2g/L的底部供水处理不但节约用水,还提高了西葫芦秧苗质量,为今后的试验提供了理论依据。By soilless culture plug seedling, the interactive application on summer squash seedlings of different watering ways and water＇retaining gel were studied. The resuhs showed that in the proper ways, the using of water retaining gel can improve the quality of summer squash seedling. The watering from the under way was also better than the watering from the top, which can save the water and reduce the times of watering and improve the quality of the seedlings. The best treatment was with water retaining gel 2 g/L and watering from the under way, which can significantly promote the growth of summer squash seedlings and improve the quality of seedling.
