| 摘 要： | 通过对中条山铜矿区尾矿坝的复田试验结果表明，３０ｃｍ，６０ｃｍ，１００ｃｍ，３各复土厚度，其土壤保肥、抗旱能力不同。在种植绿肥和施化肥后，新复田土壤熟化度在１年内达到与老复田地（１５年）熟化程度同等肥力不同，作物产量也随复土厚并增加相应增加。

| Abstract: | The relationship between crop yield and both of the soil covered thickness and properties of reclaimed land within copper mine area in Shanxi province was studied.The result shows soil Physical properties as well as the capability of drought resistance are different duing to the differences of soil covered thickness.The fertility level of one--year new reclaimed land after green manuring and fertilizing is almost equivalent to that of the fifteen years old reclaimed land.The crop yield increases with the thickness of covered soil increasing. |
