摘要： 研究了多功能保水剂对苜蓿产量的影响。结果表明：保水剂不同施用量都能提高苜蓿产量，随着施用量的增加，提高程度也加大，但从最大经济效益来讲，以3Kg/亩为最佳施用量；施用多功能保水剂还能增加苜蓿体内干物质的积累。

Abstract: This paper studied the effects of applying multi-functional water retaining agent on the yield of alfalfa. The results show that: the yields of alfalfa increase when different amount of water retaining agents are applied. The increasing rate of the yield increases with the increasing of the application rate. However, the best amount is 3 kg/mu from the point of the largest economic benefits. The application of multi-functional water retaining agent can increase the dry matter accumulation of alfalfa.
