| 摘 要： | 本实验结果表明,黑龙江省黑土施用农家肥后,土壤有机质、全氮量分别增加0.19～0.55％,0.02～0.07％,速效磷增加0.41～19.75毫克/100克土;复合胶体的数量也相应提高,增值复合量为0.16～1.04％;土壤物理性质得到改善。农家肥的应用,增强了土壤肥力的后劲。

| Abstract: | After application of farm manure to black soil, the total content of organic matter and nitrogen in black soil were increased by 0.19～0.55%, 0.02～0.07% respectively, the content of available phosphate were increased by 0.41～19.75mg/100g soil compared with the controle plot The quantity of organo-mineral complexes were raised correspondingly. The soil physical properties were improved. With the application of farm manure to black soil, the potential fertility of soil was promoted. |
