黑龙江省西部干旱区草坪草引种筛选研究

针对黑龙江省西部半干旱区较复杂的环境条件及目前草坪建植中存在的品种少和引种盲目等问题,对不同来源的8个草种32个品种的生育期,抗逆性和再生速度等进行了综合评价。结果表明,草地早熟禾属的亨特和肯塔基,紫羊茅属的J61CR278和普通紫羊茅,硬羊茅属的Osprey和斯巴达在2001年极其干旱年份越冬率、抗逆性、再生性、叶色和叶质地均较好。这6个品种是黑龙江省西部寒冷半干旱区建植草坪的优良草种,可以大力推广。

Study on the turfgrass introducing and screening in semi-arid area of western Heilongjiang Province

In order to select the adaptable turfgrass species/varieties and avoid wildly introducing,8 turfgrass speies(including 32 varieties) were used to evaluate the growth characteristics and adaptability.The results showed that Huntsville and Kentucky bluegrass from Kentucky bluegrass family,J61CR278 and Comon from Red fescue family,Osprey and Spartan from Strong fescue family performed quite better in over winter rate,resistance,leaf colour and texture.These six varieties were suitable to be extended in the western area of Heilongjiang Province.
