中文摘要	根据河西走廊灌漠土上连续27 a的长期定位试验数据,研究了河西绿洲区灌漠土有机肥和化肥长期配施对作物产量和土壤养分库的影响。结果表明,有机肥与化肥长期配施增加了作物产量和产量的稳定性;7种施肥方式(单施氮、NP配施、NPK配施、单施有机肥、有机肥+N、有机肥+NP、有机肥+ NPK)中,以有机肥与NP或NPK肥配施效果为最佳。长期有机肥和化肥配施增加了N,P,K养分投入量、养分携出量和盈余量;有机肥与化肥配施21~25 a后,土壤有机质、全氮和全磷含量分别提高了10.0%~16.0%,58.1%~69.0%和13.4%~31.1%,速效氮、速效磷和速效钾含量分别提高了45.7%~79.0%,172.2%~287.8%和21.4%~38.8%,均显著高于对照和单施化肥处理;有机肥与化肥配施处理中,以有机肥与NPK肥配施改善土壤肥力的效果最理想
英文摘要	Long-term fertilization experiment on indigenous soil of Hexi Oasis,Gansu Province indicated that 27 yearsmixed use of organic manure and chemical fertilizers increased crop yield and its stability,especially for organic manure and NP or NPK fertilizers.Long-term use of organic manure and chemical fertilizers increased N,P and K investment to soil and nutrient output from soil as well as nutrient surplus.Soil organic matter,total N,total P,available N,available P and available K content increased by 10.0%~16.0%,58.1%~69.0%,13.4%~31.1%,45.7%~79.0%,172.2%~287.8%,21.4%~38.8%,respectively after 21~25 yearsuse of organic manure and chemical fertilizers,and were significantly higher than those of single use of chemical fertilizers and the contrast.The treatment of organic manure and NPK fertilizers was the best one in improving soil fertility.
