摘　　要：在河西地区进行草坪建植试验 ,播种量范围在 1 0～ 2 5g/m2内 ,其结果播种量越大 ,单株密度越大 ,总覆盖度越大 ,成坪速度快 ,但植株细弱 ,分蘖数减少 ,次年返青率低 ;播种量低则单株密度小 ,覆盖度小 ,成坪速度缓慢 ,但植株发育强壮 ,分蘖数增加 ,次年返青率高 .试验证明在河西地区春播早熟建植草坪以 1 5g/m2The experiment was engaged in Hexi district. The results shosed that high plant density,good total coverage,rapid establishment but thin plant and poor plant tillers of the turf grown at high sowing rate of 10~25 g/m 2, except for low establishment,we got strong plant, increased tillers and at high rate of turning green in the next year. The experiment shows that it is suitable to grow Kentucky bluegrass at the sowing rate of 15 g/m 2 in spring in Hexi district.
