摘　　要：采用穴盘育苗,研究不同浓度下旱露植宝多功能保水剂与供水方式交互对辣椒幼苗生长的影响。结果表明:辣椒穴盘苗底部供水方式下灌水次数及灌水量均少于上部供水,可节约用水,最高节水率为36.98%;底部供水方式下保水剂浓度为4 g/L时对辣椒幼苗的生长量、形态指标及生理指标差异影响显著,可促进辣椒出苗,提高秧苗质量。The effects on the seeding growth of pepper（Capsicum Annuum L.） by using different content of skygel water retention agents and water supply modes through adopting plug seedling were studied.The results showed that the irrigation times and irrigation quantity of pepper plug seedling under bottom water supply were less than upper water supply,it can save water,and the water-saving rate reached 36.98%;There was concentration of water retention agents with 4 g/L on pepper＇s growth,morphological index and physiological index,and the seedling emergence rate and seedling quality were promoted.
