摘　　要：选用美国干水、多功能营养激活剂和旱露植宝3种保水材料在盐池沙地进行了造林试验。结果表明:美国干水、多功能营养激活剂和旱露植宝3种保水材料均能有效地提高植株根系周围的土壤含水量,从而促进苗木的生长和提高造林成活率,美国干水能显著提高造林成活率以及促进林木生长。Three water-retention agents,namely,American drywater,multifunction nutritional activator,Hanluzhibao,were used to conduct afforestation test on sandy land of Yanchi County.The result showed that all the 3 agents could effectively raise the water content in the soil around the plant root systems so as to promote the growth of seedling and raise the survival rate of afforestation.Among the 3 agent,American drywater performed the best.
