冷地型草坪混播组合中草地早熟禾最佳含量的研究

Study on the Optimum Percentage of Poa pratensis L. in Mixed-seeding Combination of Turf

在实验条件下，以不同配比的草地早熟禾（ＰｏａｐｒａｔｅｎｓｉｓＬ．）进行了建立混播草坪的实验，并用模糊数学综合评判法评定草坪应用性。结果表明：在混播草坪组合中，草地早熟禾的百分含量最佳配比为７０％（综合评判值为０．６１４）

A turf was established by using different percentages of Poa pratensis L. (10%～80%) under the environment condition and management level, large difference between the rate of establishment and the qualities of the turf was found. The percentage of Poa Pratensis L. was higher, the rate of establishment was slower. When fuzzy mathematics was used to determine the application's characteristics of turf, the results showed that the best percentage of Poa Pratensis L. was 70%.
