冷地型足球场草坪混播组合多年生黑麦草最佳含量的研究

The Study on the Optimum Ratio of Lolium perenne in Mixed─Seedling Cool Season Sportfield Turf

在该试验的生境和养护管理条件下，以不同配比的多年生黑麦草（Ｌｏｌｉｕｍｐｅｒｅｎｎｅ）进行了建立混播足球场草坪的试验。结果表明：成坪速度和成坪后的草坪质量差异很大。成坪速度表现为随多年生黑麦草比例的增加而增快。成坪后用模糊数学综合评判法评定草坪质量，多年生黑麦草的百分含量最佳配比为２０％（综合评判值为０．６７４），其次，多年生黑麦草的百分含量为５０％（综合评判值为０．６１２）。综合考虑成坪速度和成坪后的草坪质量，多年生黑麦革的百分含量最佳配比为２０％左右（综合评判值为０．６７４，成坪速度为１个月左右）。

The effect of different ratios of Lolium prenne(10%～80%)on establishment of mixed seeding coolseason sportfield turf were investigated under the exlperimental conditions. The results indicated thatgrowing rates and qualities of turf were remarkable different among the different ratios of L. prenne. Theestablishing rate of turf faster as the ratio increased.The quality of sportfield turf assessed using a methodof Fuzzy mathematics showed that the best ratio of L. prenne was 20%,followed by the ratio of 50%,It isconcluded that 20%of L. renne could give the good establishment of cool season sportfield turf as bothestablishing rate and quality considered.
