普那菊苣不同刈割利用方式的研究

Study on Different Cutting Methods for Puna Chicory

该试验对普那菊苣不同留茬高度与其产草量和再生速度的关系和不同刈割高度对产草量和茎叶比的影响进 行了研究,结果表明,普那菊苣留茬高度以4-6 cm为适中,株高40 cm时刈割利用,其产草量和茎叶比均较好。

In this study, the relationship between the stubble height with fresh grass yield, and the regeneration capacity and the influence of the cutting height on the fresh grass yield and the ratio of stems and leaves of puna chicory were tested. The results showed that the suitable stubble height is 4-6cm. The grass yield and ratio of stems and leaves is perfect when puna chicory is cut at 40cm.
