Spatial heterogeneity of the weed community in a manilagrass lawn

摘要

Zoysia matrella (L.) Merr.(manilagrass) can form a dense and pest‐free turf.However if mowing at low height is coupled with frequent watering, the lawn is more easily invaded by weeds.In order to evaluate the quality and sustainability of manilagrass lawn, the spatial variation and species of weed community were analyzed with a new power‐law method in this study ( Shiyomi et al., 2001 ), which is helpful to recognize the patterns of weed invasion and distribution, as well as to eventually anticipate weed population dynamics as affected by lawn management strategies.
