摘要
为了最大限度提高人工草地地上生物量,并延长草地的使用寿命,在果洛州玛沁县“黑土型”退化草地上进行了人工草地群落优化配置研究。初步确定“垂穗披碱草+中华羊茅+冷地早熟禾+波伐早熟禾”为最佳人工群落组合。
To increase above ground biomass and the year of utilization are two main purposes of grassland rehabilitation. A comprehensive seeding trial was carried out in ＂Black Soil Type＂ degraded meadow so as to determine effects of different treatments. The results showed that the optimal combination of artificial plant community was ＂Elymus nutans L ＋ Festuca sinensis Keng ＋ Poa crymophila Keng ＋ Poa poiphagorum Bor＂
