| 摘 要： | 对紫花苜蓿不同刈割期的产量及营养进行了测定。结果表明：不同刈割期紫花苜蓿的产量差异极显著（P〈0.01），第一茬最高为7473．8kg，耐，第三茬3827．9kg/hm^2，第二茬2316．2kg，雠。粗蛋白（CP）含量随刈割时期顺序变化呈下降趋势，第三茬与第一茬、第二茬差异极显著（P〈0.01）。酸性洗绦纤维（ADF）、中性洗涤纤维（NDF）含量随刈割时期顺序变化呈上升趋势，不同刈割期期间差异极显著（P〈0.01）。

| Abstract: | The yield and nutrition of alfalfa in different cutting stages were determined. The results showed that the yield of alfalfa in different cutting stages was significant （P 〈 0.01）.The first cutting yield was 7 473.8 kg/hm^2 ,the second and third cutting yield were 2 316.2 kg/hm2 and 3 827.9 kg/hm^2 , respectively.The crude protein content（CP） was tended to decrease as increaed the cutting stages,but acid detergent fiber（ADF） and neutral detergent fiber（NDF） increased significantly（ P 〈 0.01）. |
