【摘要】 根据上海市农业产业结构调整过程中对土质的要求 ,本文从资源化利用上海市城市生活垃圾的角度出发 ,将自然堆置多年的垃圾堆肥应用于土壤改良 .由于垃圾堆肥质地粗松 ,含有较高的营养成分 ,同时考虑到水稻土对垃圾堆肥的承纳量 ,本实验设计了 0、7.5、15、2 2 .5kgm-2 4个垃圾堆肥施用剂量 ,经过一个完整的生长季节后采集土壤样品进行理化分析 .结果表明 ,相较对照小区 (0kgm-2 ) ,施用垃圾堆肥可以有效地改良水稻土的物理化学性状 :有机质、全N、全P、碱解N和速效P的含量分别提高 5 %～ 2 4 0 % ,土壤中细砂含量升高 ,粘粒含量下降 .而且这种改良的效果随着垃圾堆肥施用量的增加而增加 .在不同耕作深度上 ,以 0～ 10cm土层的效果最佳 ,10～ 2 0cm次之 ,2 0～ 4 0cm最低 .本实验结果表明 ,垃圾堆肥不仅是上海市水田旱作土壤的有效改良添加剂 ,而且是解决城市生活垃圾出路的一条有效途径 .表 2参 7更多还原

【Abstract】 Composted refuse was used to reclaim paddy soil for planting flowers. Four different quantities of composted refuse were designed at 0, 7.5, 15 and 22.5 kg m -2 , respectively. After one year, the treated soil samples were taken and analyzed. Results showed that composted refuse could reclaim paddy soil effectively. The chemical characters, such as organic matter, total N, total P, available N and available P were increased from 5%～240%. The content of fine sand was increased and that of clay soil was decreased. The improvement effect was increased along with the quantity increasing of composted refuse. The 0～10 cm upper layer gained the best reclamation effect, 10～20 cm the middle, and 20～40 cm the less. Whether Aster novi-belgii L. or Buddleja davidii Franch was planted on the treated fields, the results were remarkably. Tab 2 , Ref 7更多还原
