冷季型草坪草根茎比与草坪品质的关系

The relationship between ratio of root and stem and turf quality of cool season turfgrass.

该研究通过对冷季型混播草坪 (高羊茅 +草地早熟禾 )地上、地下生物量的测定 ,结合草坪综合品质的观测 ,揭示出了冷季型草坪合理的根茎比值 .在环境胁迫严重的 8,9月份 ,发现以高羊茅和草地早熟禾占优势的混播草坪最适根茎比值为 1 0 ,而在生长条件适宜的秋季 。

A suitable ratio of root and stem of cool season turf was found out by measuring above ground, underground biomass, and by observing and rating turf quality of cool season turf mixture(tall fescue+Kentucky bluegrass). It was found that 1 0 should be taken as the most reasonable ratio in Aug. and Sept. when serious environment stress happened. However, the ratio between root and stem had no relationship with turf quality in autumn.
