摘要
本文阐述了线叶菊草地内线叶菊、禾草和杂类草营养物质的季节动态规律；根据营养动态指数和适口性等因素确定最佳刈割时期为８月上旬，即线叶菊盛花期，指出该类型草地应兼顾放牧和刈割两种利用方式，提倡线叶菊青贮。
he paper studied the seasonal dynamics of nutient substances of Filifolium sibiricum,grasses and forbs on.sibiricum grassland and determined that the optimal cutting time was the first ten day of August(F.sibiricum blooming stage).It was suggested that the proper utilization of the grassland must take account of the two using ways of graz-ing and cutting.Ensiling use of F.sibiricum was also recommended.
