摘　　要：松嫩秣食豆是黑龙江省优质的饲用豆科作物新品种,为解决松嫩秣食豆的合理利用问题,笔者在松嫩平原西部地区开展了秣食豆不同刈割时期（盛花期、结荚期、成熟期）对其产量及品质的试验研究,对松嫩秣食豆的产量和品质进行综合评价。结果表明：松嫩秣食豆在黑龙江西部地区9月初结荚期刈割其鲜草产量达63 703.70 kg/hm^2,相对饲用价值显著高于成熟期（P〈0.05）,为产量和品质的最佳平衡点。说明松嫩秣食豆最佳刈割时期为结荚期,其利用模式适宜在东北寒冷地区及类似气候地区示范推广。Glycine max（L.）Merr. Songnen is a new variety of high-quality forage legume crop in Heilongjiang Province. In order to solve the problem of rational utilization of Glycine max（L.）Merr. Songnen,experimental study on its yield and its quality was carried out at different cutting time（full-bloom stage,fruiting stage,maturation stage）of Glycine max（L.）Merr. in the western region of Songnen plain,and the yield and the quality of Glycine max（L.）Merr. Songnen at different cutting time were comprehensively evaluated. The results showed that fresh grass yield of Glycine max（L.）Merr. Songnen at fruiting stage reached 63 703.70 kg/hm^2 at the beginning of September in the western region of Heilongjiang,which had higher relative feed value than that at maturation stage（P〈0.05） and was the best balance between yield and quality. The results suggested that fruiting stage was the best cutting time for Glycine max（L.）Merr. Songnen,and its utilization pattern was suitable for demonstration and promotion in cold northeast region or similar climate regions.
