摘　　要：对5种常见暖地型草坪草在不同遮荫条件的成坪速度及其景观效果进行研究观察,结果表明:天堂328、狗牙根、结缕草均随遮荫程度的加大,成坪速度显著减慢或不能成坪,假俭草、马尼拉在遮荫度37%、58%条件下,成坪速度超过对照水平或相当,因此认为,在遮荫地或林下种植草坪时,供试草种中应首选假俭草,其次为马尼拉,另外3个草种不宜作为耐荫草种利用;遮荫提高了各草坪草叶片的叶绿素含量,一定程度上增加了绿色景观效果;遮荫处理不同程度增加了草坪植株的高度、叶片长度、宽度、面积,但降低了叶片的厚度。The effect of shading on turf quality and establishment speed using 5 turfgrasses were studied and the result indicated that the establishment speed of Tifton 328, Cynodon dactylon, Zoysia japonica was reduced along with the degree of shading, and it was almost same for Eremochloa ophiurodes and Zoysia matrella under 37% and 58% of shading. It is conduded that Eremochloa ophicuroides and Zoysia matrella are proper species for turf under shading condition. The content of chlorphyll in leaf was inceased to a certain degree through shading treatment and the height, length, area and broadth of leaf were also increased by shading, but the thickness of leaf was decreased.
