环渤海低平原旱碱区冷季型草坪草适宜草种鉴定研究

Appraisal Research on Suitable Turfgrass on the Low-Lying Land around the Bohai Sea.

针对环渤海低平原区较复杂的环境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 ,对引进的 7个草种 4 7个品种的生育期、抗逆性、坪用价值等进行了综合评价。结果表明 ,高羊茅、白三叶为最适合的草种 ,草地早熟禾和百脉根较适合 ,多年生黑麦草不适宜单播但可以与高羊茅和草地早熟禾以适当的比例混播 ,紫羊茅和红三叶不适宜在该区种植 ;最优良的品种高羊茅为皇后、贝克 ,白三叶为拉吉诺白三叶、威亚白三叶 ,草地早熟禾为亨特、普通、兰神、奖品 ,百脉根为哥拉吉亚 1。

To counter the complex environmental condition, adverse soil condition and the blind introducing variety tendency on turfgrass constructing as well as the high failure rate, short life span and other problems,47 grass varieties that belongs to 7 grass species were introduced.Meanwhile,the growing period, property of resistance,turf quality were evaluated comprehensively.The results showed that Tall Fescue and White Clover is the most suitable grass species, the Kentucky Bluegrass and Lotus Corniculatus is the relative suitable grass species and the Perennial Ryegrass can't be sowed alone,but it can be sowed with Tall Fescue and Kentucky Bluegrass in proper proportion.Red fescue and Red Clover is unsuitable to this region.The most suitable varieties of Tall fescue are Empress,Pixie.The most suitable varieties of White Clover are Largeno White Clover and Viya.The most suitable varieties of Kentucky Bluegrass are Hunt,Common,Nublue,Award.The most suitable varieties of Lotus corniculatus is Gerogiaone.
