环渤海旱碱区冷季型草坪草引种筛选研究

针对环渤海低平原区较复杂的环境条件、恶劣的立地条件及目前草坪建植中存在的引种盲目、失败率高、寿命短等问题,通过对引进的4个草种37个品种的生育期、抗逆性、坪用价值等进行综合评价,鉴定出高羊茅为最适合的草种,草地早熟禾较适合,多年生黑麦草不适宜单播,可以和高羊茅以适当的比例混播,紫羊茅不适宜在该区种植。筛选出最优良的品种高羊茅为皇后、贝克,草地早熟禾为亨特、普通、兰神、奖品。

The preliminary study on introduction and screening of cold-season turf grass in the dry and alkali area around the Bohai Sea

In consideration of resolving the problems existing in turf sector, especially the improper turfgrass introduction, 37 turfgrass varieties, which belong to 4 species were introduced and evaluated with the growth period, resistance and turf quality comprehensively. The result showed that tall fescue was the most suitable species, which followed by Kentucky bluegrass and perennial ryegrass (in which, the latter was not suitable for sole sowing and better to be used together with tall fescue). Red fescue was unsuitable in this region. The most suitable varieties of tall fescue are Empress and Pixie. Hengte, Common, Nublue and Award were the most suitable varieties from Kentucky bluegrass.
