基于中国科学院长武试验站王东沟模拟弃土场的长期定位试验,分析了不同施肥下植物对弃土场土壤改良的效果。不施肥与施有机肥处理下各植物小区土壤水分较对照有明显的提高;三种处理下土壤容重和孔隙度均有所改善;施入有机肥和秸秆能够明显增加土壤中有机质含量,有机肥处理下增加量高于秸秆,各处理下土壤有机质含量在第一年基本呈下降的趋势;有机肥和秸秆的施入能够增加土壤中全氮和铵态氮的含量;三种处理对于增加土壤有效磷含量均有很明显的效果;施入有机肥和秸秆极大地增加了土壤中有效钾的含量,有机肥处理下各植物小区平均含量较基土值有所降低,不施肥和施秸秆处理下各植物小区平均含量分别较对照和基土值均有所增加。

Based on the long term location test of simulation spoil ground in Wangdonggou, Changwu Agro-Ecological Experimetal Station, we studied the effects about soil improvement of plants with different fertilization. The results showed that the soil moisture of plant communities of no fertilizer and organic fertilizer processing has obvious increase than control. The soil bulk density and porosity improved in three treatments. The content of soil organic matter increased significantly in utilizing organic fertilizer and straw, and the increasing in organic fertilizer is higher than straw, but it decreased generally at the first year in three different managements. In addition, total nitrogen and ammonium nitrogen in the soil increased under taking organic fertilizer and straw. The content of available phosphorus increased in three treatments. Also, the content of available potassium increased greatly under taking organic fertilizer and straw. However, the average available potassium in the soil of different plant communities are less than the standard in organic fertilizer, no fertilizer and straw increased oppositely.
