摘 要: | 设4个遮荫梯度(0、20%、40%、70%),对遮荫生境下粤选1号匍匐翦股颖新品种草坪草植株形态进行了初步研究。结果表明:在遮荫条件下,粤选1号随着遮荫强度增加,叶片变长;分蘖减少,密度变小;根长变短,根系变浅;叶片宽度变化不明显;叶绿素含量略有下降;70%以下的遮荫对粤选1号草坪景观价值未造成影响,粤选1号可在70%以下的遮荫地大面积推广应用。

Abstract: | The morphology of shading treatment on the Agrostis stolonifera L. cv. Yuexuan No.1 were studied in four shading condition (shading 0percent,20percent,40percent,70percent).The results indicated that leaf blade length of the YuexuanNo.1 become longest,the tiller of lawns was decreased,density of lawns was diminished,root length of lawns was shorten and root System was shoaled,the breadth of leaf was inapparent changed,Chlorophyll content of lawns was descend in some sort in Shading treatment along with shading intensity increased. landscape quality of lawns had no influence on the Yuexuan No.1 under 70 percent shading condition,therefore Yuexuan No.1 can extend and appliy in large area under 70 percent shading condition. |
