不同处理下大叶油草草坪坪用性状的研究

用几种处理法在广州地区园林常见草坪--大叶油草Axonopus compressus草坪上进行冬绿技术研究,结果表明:从草坪冬季的景观来看,用盖播处理法的保绿效果远优于高水肥管理法;同时从盖播草坪杂草的发生情况来看,盖播处理区草坪杂草的发生率远低于水肥处理区.此外,试验还表明尽管水肥处理区的经济成本略低于盖播处理区,但水肥处理一方面耗费更多的水资源,另一方面可能排放更多的潜在污染源.而使用盖播法的资金投入主要在于草种和用工开支,这一特点不仅环保,而且有利于商业化经营.

Winter turf characteristics of carpetgrass under different treatments

Winter-green technology was studied using several t re atments on carpetgrass turf commonly found in gardens in the Guangzhou region. From the aspect of winter turf looks, the effect of oversowing was much better a t keeping the turf green than the high water and fertilization treatment. The o ccurrence of weeds in the oversown turf was also much lower than in the water an d fertilization treatment. The trial also indicated that although the cost of t he water and fertilization treatment was slightly lower than oversowing, it used more water and maybe discharged more latent contaminating sources. The capital in oversowing is mostly invested in grass seed and in hiring labour, this pecul iarity therefore not only protecting the environment but beneficial to commercia l management.
