摘  要:
1978~ 1998年在陕西关中地区农田的长期定位试验研究表明 ,长期单施化肥基本上可以维持土壤有机质和NP水平 ;单施化肥与化肥配合有机肥处理的作物产量基本相当 .但是 ,单施化肥处理使土壤腐殖质能量水平降低 ,分子缩合程度和芳构化度增大 ,“老化”作用增强 .

摘  要:
A long-term located experiment showed that single application of chemical fertilizer basically sustained the quantity le- vel of soil organic matter,nitrogen and phosphrous,reduced the energy level of soil humus and inhanced its condensation degree,aromaticity and aging function.The corp yield was basically the same as that of combined application with organic manure.
