| 摘 要： | 为了妥善处置和利用城市污泥,使之变废为宝,采用城市污泥对毛白杨进行了不同立地施肥量、施肥时期试验.结果表明,污泥施肥改善了林地土壤的理化性状,对土壤具有修复作用.在不同施肥时期,不同立地条件下,施入一定量的城市污泥对毛白杨株高、胸径的生长均有促进作用,平原林地毛白杨净生长量优于丘陵地,污泥施入量以75 kg/株效果最佳.

| Abstract: | As a kind of by-product of waste water treatment,municipal sewage sludge contains a large numbers of nutrients in terms of N,P and organic matter,as well as some harmful and poisonous substances.The municipal sewage sludge as soil improvement on Populus tomentosa woodland was studied primarily in this paper.The results showed that the soil quality and tree growth were greatly improved by sewage sludge.The amelioration effect depends on the quantity of fertilization,soil quality and tree age.For a 6-year-old Populus tomentosa plantation on poor soil,75 kg /stem was recommended. |
