土壤施加垃圾堆肥的允许负荷量

ALLOWABLE LOAD OF THE GARBAGE COMPOST APPLIED TO SOILS

利用城市生活垃圾堆肥进行生菜、青莱、小麦三种作物的盆栽试验，并根据作物中金属元素Ｃｄ、Ｃｕ、Ｃｒ、Ｐｂ、Ａｓ的含量，探讨了三种土壤施加垃圾堆肥的效果及允许负荷量。结果表明：土壤消纳垃圾肥的潜力很大，但不同土壤类型对垃圾肥的负荷量有明显差异。

Compos made from municipal domestic garbage was used for the tests of potted plantation of romaine lettuce,green vegetable and wheat,and the effects and allowable load of the garbage compost applied to 3 types of soils,yellow brown earth,fluvo-aquic soil and red earth were studied based on the metal contents (Cd,Cu,Cr,Pb,As) in potted plants. The results indicated that the acceptance of garbage by soil was greatly potential, but obviously affected by soil types and crop varieties.
