摘要
作者经过３年的试验，对引自美国、加拿大的１５种草坪型草地早熟禾在宁夏引黄灌区的物候期、生长特性以及种子生产性能进行了较为系统的研究。结果表明，所有参试品种在银川地区均可结实，但抽穗率和结实性能差异极大，以Ｐａｒｋ、Ｍｅｒｒｙ、Ｎａｓｓａｕ、Ｓｕｆｆｏｌｋ、Ｃｏｍｍｏｎ等最佳。因此，作者认为，在宁夏引黄灌区建立草坪型草地早熟禾种子生产基地是完全可行的。
The phenology, growing characteristics and seed productivities of 15 varieties f or turf-type Poa pratensis, which introduced from United States and Canada, were systemically studied in the Yellow River irrigation area of Ningxia through 3-year experiments. It is indicated that all of the tested varieties can produce seeds in Yichuan region, and the tasseling rate and fecundity rate are different significantly. The varieties of 'Park', 'Merry', 'Suffolk' and'C ommon'give the highest seed yields. Therefore, it is practical to establish see d production base for turf-type kentucky blue grass (Poa pratensis) in the irrigation area of Ningxia.
