| 摘 要： | 通过对干热河谷地区10个紫花苜蓿品种在孕蕾初期进行刈割1茬和不刈割处理后,从其种子成熟时间、产量方面,研究刈割对该区引种的紫花苜蓿品种种子生产的影响,以提高其种子生产性能。结果表明:在干热河谷地区,在紫花苜蓿孕蕾初期刈割1茬后,种子产量平均提高14.933 g/m2,并促使种子主要集中在播种次年的5月份成熟采收;10个参试紫花苜蓿品种中,猎人河(74-55)的种子平均产量显著高于其他品种,可达36.401 g/m2,其次是萨兰纳斯(75-43)和德宝,其种子平均产量分别为31.727 g/m2和30.060 g/m2。

| Abstract: | The seed production perfotmeance of Medicago sativa in dry-hot valley region was studied.The results indicated that the seed production of Medicago sativa was improved after cutting 1 stubble and impeling the seeds maturitied on May in ensuing year;The average yield of 36.401 g/m2 for Hunter-river(74-55)seeds was the highest,and that of 31.727 g/m2 for Sa Lan na si(75-43)seeds was the second highest. |
