| 摘 要： | 对经堆处理的污泥有机肥培育结缕草（Zoysia japonica)的初步研究表明，在污泥符合农用标准条件下，以Cd为施污泥肥厚的限制因子，在施污泥有机肥45t.hm^-2（干重）以下时，在微酸性土壤（PH＜6．5），土壤Cd含量低于Cd的土壤环境质量标准（0.3mg.kg^-1)，地下水NO^-3-N含量低于地面水Ⅰ、Ⅱ类标准（NO^-3-N10mg.kg^-1,P0.1mg.kg^-)，土壤中有机质，速效N、总N、总P分别经对照增加16％、78％、61％和140％，结缕草生物量比对照区高1倍，可以认为，污泥草地利用是一种良好途径。

| Abstract: | The experiment of sewage sludge composted as fertilizer for Zoysia japonica was conducted, and the results showed that Cd content in soil was lower than 0.3 mg.kg-1 under the condition of the fertilizer application lower than 45 t.hm-2 (dry weight) and the pH value of soil lower than 6.5 (Cd as the limiting factor for the amount of fertilizer application). NO3(-)-N content of groundwater was lower than the standard of the first class groundwater (10 mg.kg-1). The contents of organic matter, available N, total N, and total P were higher than those under control by 16%, 78%, 61%, and 140%, respectively. The biomass of Zoysia japonica was increased two times against the control. Therefore, sewage sludge utilized as fertilizer for grassland might be a valuable approach. |
