摘要
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。
An investigation of different mowing heights on turf grass community structure which mixed by tall fescue( Festuca arundincea) and kentucky bluegrass ( Poa pratensis) was conducted. The results showed that chipping height at 2 cm during establishing stage and mowing height at 8 cm during turf maturating period were helpful to keep the stability of community in humid subtropical area. Higher mowing height( 8 cm) increased nutrient accumulation and roots amounted to 1.959 2 g(10 cm×10 cm×30 cm underground). With the decreasing of mowing height, the leaf blades became narrow for tall fescue and wide for kentucky bluegrass.
