| 摘 要： | 土壤长期定位试验结果表明作物连作条件下,施肥各处理作物产量高于不施肥处理,且有机肥优于化肥,化肥优于秸秆还田.施肥提高了土壤有机质及N、P、K养分含量,施有机肥土壤养分含量增加显著.在小麦、玉米、大豆作物中,小麦连作条件下,施肥利于土壤养分的积累.

| Abstract: | The results of soil long-term located experiment showed that the crop yields would be increased resort to fertilizing than no fertilizing and OM>NP>TS on continuous cropping. Application of fertilizers raised the contents of soil organic matter and NPK, and significant in application manures. Fertilization favoured accumulation of soil nutrients best on wheat continuous cropping in three crops. |
