摘要
施用污泥堆肥后,木槿、月季、美人蕉及旱荷花的开花量增加,花期延长,金枣、龟背竹与五叶地锦的各生长参数也明显增大;土壤理化性质有明显改善;当污泥堆肥施用量小于9Kg/m^2时,无因盐分、NO_3^-—N淋溶及地面径流而造成的环境问题.
After the sewage sludge compost was applied to the media and plots, the number of the flowers and the blooming period of rose of Sharon (Hibiscus Syriacus L. ), Chinese rose (R. Chinensis Jacq. ), Nasturtium (Tropaeolum Majus L. ) and Canna (C. Indica L. ) increased; the growth parameters of the Kumquat CFortunella nargarita (Lour. ) Swingle], Ceriman (Monstera deliciosa Liebm) and five -leaf humid euphorbia (P. quinquefolia Planch) increased, too. The physical and chemical properties of the soil had beneficial changes. When the sewage sludge compost application rates didn't exceed 9 kg/m2, there were no salinity affect and nitrate leaching as well as runoff pollution problem.
