| 摘 要： | 研究了多功能保水剂对苜蓿产量的影响。结果表明：施用不同剂量的保水剂均能提高苜蓿产量，随着施用量的增加，产量也在增加，但从最大经济效益来考虑，以666．7m^2施用3kg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: | In this paper,the effect of applying multi-functional water retaining agent on the yield of alfalfa was studied.The results showed that the yield of alfalfa increased when different amount of water retaining agents were applied,and the yield increased with the increase of the agent application rate.However,the best amount was 3 kg per 666.7m2 considering for the largest economic benefit.The application of multi-functional water retaining agent could also increase the dry matter accumulation of alfalfa. |
