摘　　要：试验对紫花苕挤压出水40%和50%后烘干与原草直接烘干和晒干进行比较,结果表明,挤压出水40%和50%后烘干比原草直接烘干缩短烘干时间12和13h;比晒干缩短66和67h;DM获得率比原草直接烘干低0.02%和0.19%,比晒制干草高7.9%和3.8%;挤压出水40%后烘干的DM、CP、EE、CF、CA、Ca损失率分别为2.05%、4.22%、7.92%、1.09%、7.94%、9.44%;挤压出水50%后烘干的DM、CP、EE、CF、CA、Ca损失率分别为6.15%、9.32%、26.16%、4.28%、15.17%、15.89%;晒干的DM、CP、EE、CF、CA、Ca损失率分别为9.74%、14.45%、42.94%、16.15%、15.67%、17.07%。且挤压出水40%和50%后烘干相比,经济效益分别提高了177.67%和176.72%。The experiment was compared medicago tiaoxi by squeezing water 40% and 50% with drying directly and sun-air drying. The results showed that the drying of squeezing water 40% and 50% drying time shorter than drying directly（12 hours and 13 hours）, shorter than sun-air drying（66 hours and 67 hours）, the DM lower than drying directly（0.02% and 0.19%）, higher than sun-air drying（7.9% and 3.8%）; the drying of squeezing water 40% DM, CP, EE, CF, CA, Ca loss rate were 2.05%, 4.22%, 7.92%, 1.09%, 7.94%, 9.44%; the drying of squeezing water 50% DM, CP, EE, CF, CA, Ca loss rate were 6.15%, 9.32%, 26.16%, 4.28%, 15.17%, 15.89%; the drying of sun-air DM, CP, EE, CF, CA, Ca loss rate were 9.74%, 14.45%, 42.94%, 16.15%, 15.67%, 17.07%. The economic benefic of squeezing water 40% and 50% with drying drircctly increased 177.67% and 176.72%.
