在不同的光照强度 (光照 150 0 0～ 2 0 0 0 0lx ;遮荫 30 0 0～ 4 0 0 0lx)和不同的播种量 ( 2 5、4 0g/m2 )条件下 ,对建植 3个月高羊茅草的生长及草坪质量进行了研究。结果表明 ,光照条件下草坪草表现优于遮荫。遮荫严重影响高羊茅的生长 ,降低草坪质量。遮荫条件下对氮的吸收减少 ,对钾的吸收有所增加。而播种量对草坪草的影响则相对较小 Under the conditions of different light intensity (light 150 0 0 ~ 200 000 lx; ​​shade 30 0 0 ~ 4 0 0 0 lx) and different seeding rates (2 5, 40 g / m 2), three Forsythia on the growth and lawn quality were studied. The results showed that lawn grass performed better than shade under light conditions. Shading seriously affects the growth of tall fescue and reduces the quality of the lawn. Under the shade condition, the absorption of nitrogen decreased, and the absorption of potassium increased. The amount of seeding grass lawn impact is relatively small
