摘要
通过对青海草地早熟禾不同刈割强度下再生性的研究,结果表明:刈割高度与频度不同,牧草再生能力不同。低茬高频的刈割,即留茬高度5cm、刈割频度7天/次,青海草地早熟禾再生性达到最佳水平,产草量也随之增加。
Through studies on the regeneration of Poa pratensis L. cv. Qinghai under, different mowing intensity, results indicated that the reproductive property was changed under different mowing hight and frequency. When the low stubble and high frequency mowing were 5cm and 7 days per time respectively, pratensis U cv. Qinghai reached the best levels, and the outputs of forge also increased.
