| 摘 要： | 在江河源区"黑土型"退化草地上用垂穗披碱草Elymus nutans+冷地早熟禾Poa crymophila+中华羊茅Festuca sinensis+碱茅Puccinellia tenuiflora混播建植栽培草地,自生长第2年起连续2年于7月26日-10月6日进行间隔10d的刈割试验。结果表明:2龄草地8月26日刈割牧草鲜草产量最高,为31933kg/hm2,3龄草地8月16日最高,为9520kg/hm2。营养物质的测定表明,8月16日刈割牧草粗蛋白产量最高,2龄为5683kg/hm2,3龄为2189kg/hm2。研究得出8月16-26日是该地区多年生栽培草地的最佳收割时期。

| Abstract: | The clipping experiment was conducted every ten days from July 26 to October 6 in the past two years on the mixed-sown artificial grassland,which was established withmixture of Elymus nutans + Poa crymophila + Festuca sinensis + Puccinellia tenuiflora in the Black Soil Type degraded grassland of source region. The results indicated that the fresh grass yield of 2-year old mixture grassland clipping firstly in August 26 was the highest for 31 933 kg/hm2,and 3-year old mixture grassland clipping in August 16 ... |
