摘　　要：通过田间定位试验 (30 .0 m2 /处理 ) ,重点探讨了轻、中度污染酸紫泥、黄泥田两种类型水稻土施用钙镁磷肥、高温碱性硅渣、腐殖酸矿粉、石灰 4种改良剂的合理施用技术、改良效应与机理 ,并通过田间微区 (1.0 m2 /小区 )试验 ,研讨了改良配合施用的改良效果 ,提出了 2组投入强度小。By field orientation test(30 0m 2 disposed), we focues attention on inquiring into the reasonable applying techology,improvement effect and mechanism of applying 4 kinds of improving agents which are calcium magnesium phosphate, hightemperature alkaline silica residue,humic acid mineral powder and lime in the two types of paddy soil:middlepollution acid purple paddy soil and slighy,middlepollution yellw paddy soil. Through field micro area (1.0m 2/tiny area) test, discussed the improving effect of applying improving agent cooperatvely, then put forward two cooperative applying sets with low investment intension, notable results of lowering cadmium and having no effect on production.
