    滑子菇渣与猪粪不同配比对堆肥腐殖质组成的影响

    Effects of different ratios of Pholiota nameko residue to pig manure on compost humus composition

      摘要
    • 摘要:
      目的  探究不同施肥配比对堆肥腐殖质组成的影响。
      方法  以滑子菇渣为基础材料，通过添加不同比例猪粪，对腐殖质的结构进行分析，并筛选滑子菇渣与猪粪堆制有机肥料的最佳配比。
      结果  滑子菇渣与猪粪不同配比堆肥的水溶性有机物以及胡敏酸碳的含量均随着堆肥过程先下降，再缓慢上升；胡富比均在15 d时显著下降，随着堆肥进程胡富比有所上升，堆肥结束时处理Ⅰ、Ⅱ、Ⅲ、Ⅳ和Ⅴ(滑子菇渣︰猪粪质量比分别为0︰10，1︰9，3︰7，5︰5和7︰3)的胡富比均显著高于起始值，分别是起始值的7.14、3.23、1.22、4.38和2.52倍，且处理Ⅳ的胡富比处于最佳水平；处理Ⅳ的胡敏素碳含量高于其他处理。
      结论  滑子菇渣与猪粪按不同配比堆肥与单施滑子菇渣或单施猪粪处理相比，腐殖质组分有机碳量更具优势，有利于堆肥腐殖质的组成含量及土壤肥力的提高。合适的滑子菇渣与猪粪配比条件下，随着胡富比的增加，土壤腐殖质的聚合程度以及腐殖化度提高。有机物料能够提高各结合形态腐殖质含量，改善土壤有机质结构，滑子菇渣与猪粪质量比为5︰5时，效果相对好于其他处理。

       

      Abstract:
      Objective  To explore the effects of different fertilization ratios on compost humus composition.
      Method  Pholiota nameko residue was selected as the basic material. Different proportions of pig manure were added to analyze humus structure, and screen the best ratio of P. nameko residue to pig manure while composting organic fertilizer.
      Result  In the compost with different ratios of P. nameko residue to pig manure, the contents of water soluble organic matter and humic acid carbon all decreased firstly and then increased slowly as the composting process continued. The ratios of humic acid to fulvic acid (CHA/ CFA) all decreased significantly on the 15th day, and then increased. CHA/CFA in treatment Ⅰ, Ⅱ, Ⅲ, Ⅳ and Ⅴ(the mass ratios of P. nameko residue to pig manure were 0︰10, 1︰9, 3︰7, 5︰5 and 7︰3) were significantly higher than the initial values, being 7.14, 3.23, 1.22, 4.38 and 2.52 times of the initial values respectively. CHA/ CFA in treatment Ⅳ was the best level. Meanwhile, the carbon content of humin in treatment Ⅳ was higher than those in other treatments.
      Conclusion  In compost with different proportions of P. nameko residue and pig manure, the organic carbon contents are more beneficial, and the humus composition contents and soil fertility are improved, as compared with using P. nameko residue or pig manure alone. Under the appropriate proportions of P. nameko residue and pig manure, the polymerization and humification degrees of soil humus improve with the increase of CHA/CFA. Organic material can improve the humus content of each combination form and the structure of soil organic matter, and the effect is better than other treatments when the ratio of P. nameko residue to pig manure is 5︰5.
