摘要
1999～ 2 0 0 1年在大兴安岭进行了林间草地牧草产量及营养品质测定。结果表明 ,大兴安岭草地小叶章占优势地位 ,牧草产量随年度和降水变化无明显差异 (P >0 0 5 ) ;小叶章在抽穗期营养品质最佳 ,野豌豆在盛花期营养品质最佳 ,杂类草在初花期营养品质最佳。由此确立大兴安岭草地在品质最佳期前是良好的放牧地和割草地。
The interforest grassland yield and its nutritive quality were tested in Daxinganling from 1999 to 2001. Results showed that Deyeuxia angustifolia(0.61610.6458)occupied dominant position in the Daxinganling grassland.There were no obviously difference of yields under the change of the year and precipitation.The nutritive quality of the Deyeuxia angustifolia was the highest in the early heading stage, Vicia cracca(0.18850.2128) was the highest in the full flowering period.The weeds was optimum in the initial flowering period.Therefore, Daxinganling grassland is a suitable grazing and mowing meadow in the best quality period.
