西宁地区春播草地早熟禾播种量对草坪建植质量的影响

The Effect of Kentucky Bluegrass Spring Sowing Rate on the Turf Establishment Quality in Xining District

在西宁城北校园区进行草坪建植试验结果 ,在 1 0g/m2 ～ 2 5g/m2 播种量范围内 ,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 ,分蘖数增加 ,次年返青率高。本试验表明 ,在西宁地区春播早熟禾建植草坪以 1 8g/m2 的播量为宜。

The experiment was engaged in the compus in Xining,the results showed that high plant density,good total coverage,rapid establishment and thin plant.Poor plant tillers of the turf ware got at high sowing rate and were turned out contrary at low sowing rate within the range of sowing rate 10g/m 2～25g/m 2,but the plant grows thin and the tillering decreases as well as the lower rate of turnning greenagain.The result is confrary to the less soron quantity.According to the appropriate londitions,the authen holols that setting up lown of poapratensis sllowd limitted in 18g/m 2 in Xining district.
