Abstract：Results of a series observation, selections and studies proved that Paspalum notatun Flugge is the best covering crop for tropic and subtropical regions at present. Paspalum notatun Flugge has characteristics of strong endurance of poor soil, drought, acid, alkaline, trample, soak and moderate endure of shade, therefore, it can be extensively planted on slopeland, grass waterways ditches, hillside ditches, farm roads. Observations indicated that these conservation practices will be well protected, farmland will be decorated in green and the ecological conservation will be achieved once ground is widespreadly covered by Paspalum notatun Flugge . In addition, results of plot runoff studies also proved that both soil losses and peak flow can be reduced significantly for slopeland covered with Paspalum notatun Flugge . Paspalum notatun Flugge has been proved to be a soil conserving crop and soil building crop as well.
