| 摘要: |
| 1981～1990年在关中塿土进行了肥料定位试验的研究,结果表明:氮与磷或厩肥配施具有显著的增产作用,氮与厩肥配施产量高于氮磷配施。长期施用厩肥显著地提高了土壤有机质、全氮、全磷、碱解氮及有效磷等养分含量。施用化肥对土壤有机质和全氮含量无明显影响,但施用氮肥和磷肥分别显著地提高了土壤碱解氮和有效磷含量。 |

| Abstract: |
| The Long-term fixed-position fertilizer experiments were conducted in the years of 1981 - 1990 on Lou soil. The results showed that N and P fertilizers or manure in balance application had a significant yield increasing effect and N fertilizer and manure in balance application produced higher yields than those by N and P fertilizers in balance application. Long-term application of manure can improve soil organic matter, total N P and alkalized N and available P nutrients. Application of chemical fertilizer had no apparent effect upon soil organic matter and total N content,but application of Nfertilizer and P fertilizer can raise soil alkalized N and available P contents |
