通过连续 8年长期定位试验 ,研究了不同施肥方式对燕山山麓平原高产粮区褐土土壤肥力和作物产量的影响。结果表明 ,褐土养分贮备及转化潜力较低 ,采用有机肥 (物 )料配施化肥 ,可明显提高土壤有机质和全量养分、速效养分含量 ,促进有机无机复合状况和腐殖质结合形态、腐殖质组成及其性质的改善 ,增强土壤酶群体活性 ,改善土壤水分及物理性质和微团聚体组成 ,较单施常量化肥具有极显著的增产作用。但在配施同量化肥条件下 ,不同有机肥 (物 )料培肥增产效果无显著差异。 Through eight years of long-term experiment, the effects of different fertilization methods on soil fertility and crop yield of cinnamon soil in the high-yielding grain-planting area of ​​Yanshan foothills plain were studied. The results showed that the nutrient reserves and conversion potential of brown soil were low, and the application of organic manure (material) with chemical fertilizers could obviously increase the contents of soil organic matter, total nutrients and available nutrients, and promote the organic and inorganic complexation and humus composition, humus composition and The improvement of its properties, the activity of soil enzyme groups, the improvement of soil moisture and physical properties and the composition of microaggregates have a significant increase in yield compared with that of single fertilizer. However, with the application of the same amount of chemical fertilizer conditions, different organic fertilizer (material) material fertilization no significant difference in yield.
