草坪型扁穗牛鞭草种质资源的坪用价值初步评价

采用景观-性能-应用适合度的综合评价体系，以暖季型狗牙根和冷季型高羊茅为对照，分春季、夏季、秋冬季对西南地区扁穗牛鞭草坪用性状和使用性能进行评价，结果表明：春季草坪景观质量H050、H049的坪用性状好于对照；夏季H036、H049、H011坪用性状好于对照；秋冬季H036、H049表现好于对照；综合一年的表现进行指标权重分析，H036、H049得分分别为17．60和18．08，可作为过渡性气候区建植观赏草坪、游憩草坪、运动草坪、保土草坪的优质材料进行开发利用。

The Turf-value Evaluation of Hemarthria compressa Germplasm Resources

Using the synthesis appraisal system of visual-performance-suitability, the turf characteristic and performance of Hemarthria compressa in the southwest region in China was evaluated in the spring, summer, autumn and winter,with bermudagrass and tall rescue as warm-grass and cold-grass contrast respectively. The results showed that in the spring, lawn landscape qualities of H050 and H049 were more excellent than that of contrast. And in the summer H036, H049 and H011 were better than the contrast in the performance, then in the autumn and winter, H036 and H049 had an advantage over contrast in the performance. After integrated indicator weight in a whole year, H036 and H049, with the score of 17.60 and 18.08 respectively, could be planted as landscape lawn, open lawn, sports lawn and ecological turf in the transitional climate zone.
