通过不同刈剪高度 (2 cm、4 cm、6 cm、8cm)对 80 %苇状羊茅 +2 0 %草地早熟禾混播草坪群落结构的影响进行研究 ,结果表明 ,亚热带湿润地区苇状羊茅 +草地早熟禾混播草坪早期低刈剪 (2 cm)、成坪后高剪 (8cm)有利于保持群落的稳定性。高剪 (8cm)营养物质累积较多 ,地下 10 cm× 10 cm× 30 cm根重达 1.9592 g。随着刈剪高度降低 ,苇状羊茅叶片变窄 ,草地早熟禾叶片加宽。
The effects of different forage height (2 cm, 4 cm, 6 cm, 8 cm) on the structure of turfgrass community with 80% reed fescue and 20% turfgrass were studied. The results showed that in the subtropical humid area, + Older grass mixed grass lawn early low mowing (2 cm), after cutting high shear (8 cm) is conducive to maintaining the stability of the community. High-shear (8cm) nutrients accumulate more, underground 10 cm × 10 cm × 30 cm root weight of 1.9592 g. With the reduction of mowing height, the leaves of tall fescue became narrower and the leaves of broadleaf trees became wider.
