为了确定三江源区黑土滩栽培的适宜牧草,自20世纪90年代末开始,在果洛藏族自治州的达日县和玛沁县引进50个牧草品种进行引种筛选试验。试验结果表明,外来草种在黑土滩上引种栽培很难成功,而青海草地早熟禾等6个乡土草种应作为当前黑土滩治理中大面积推广应用的首选草种;麦宾草等草种可作为黑土滩治理的后备草种,并提出了黑土滩人工草地建植的牧草混播组合。
In order to determine the suitable forage for cultivation of black soil in Sanjiangyuan area, 50 forage varieties were introduced in Dali County and Maqin County of Guoluo Tibetan Autonomous Prefecture from the late 1990s to introduce and select forage. The results showed that introduction and cultivation of exotic grass species on black soil beach were very difficult to succeed. Six native grass species, such as Poa pratensis in Qinghai Province, should be the preferred grass species for large-scale popularization and application of black soil beach management. It can be used as backup grass for the treatment of black soil beach, and put forward the combination of forage grass planting of artificial grassland of black soil beach.
