植物残体对土壤结构性状的影响

Effects of plant residues on soil structure

  • 摘要: 试验研究了有机肥、亚锭造纸制浆黑液(SWUA)和化肥对砂壤质水稻土结构的影响。结果表明,施用有机肥的水稻土孔隙度、水稳性团聚体和持水能力等性状显著忧于黑液处理和化肥处理;秸秆直接还田最有利于土壤结构改善;土壤毛管孔隙范围内水分最活跃孔径为0.05~O.10mm,其孔径孔隙度与土壤持水能力呈明显线性关系。

     

    Abstract: The effects of organic manure,tstraw-paper-pulping waste using ammonium sulphite(SWUA)and chemical fertilizer on the soil structure of sandy Loamy paddy are studied.The resuts show that the soil porosity.water-stable aggregate and water-holding ability of organic manure treatments are significantly higher than those of other treatments among organic manure treatments,plant residue is the most favourable to improve soil structure,and the diameter of pore in which water can most actively move is O.O5~O.1Omm among capillary.There is a significant linear relationship between the porosity 0.O5~0.10mm in diameter and the water-holding capacity of soil.
