| 摘 要： | 黄土高原区长期定位试验麦秸、玉米秸、绿肥、厩肥及化肥等培肥物质对土壤养分及小麦产量的影响结果表明,长期施用有机肥可明显提高土壤有机质、全量养分和速效养分含量,提高土壤酶活性,改善土壤有机无机复合体、土壤水分、物理形状和土壤团聚度,提高调节土壤水、肥、气、热等能力,其中秸秆增产效果最显著。

| Abstract: | A long-term experiment on Loess Plateau shows that the long term application of organic manure,the content of soil organic matter and total and available nutrients can be raised and the soil organic-inorganic complex soil enzyme activity,soil moisture and physical characters,and soil gather together degree also be improved.Finally,the regulate capability of moisture,fertilizer,air,hot are raised.The increased yield effect of a long-term application of straw is the best. |
