对三江平原典型白浆土进行田间试验。结果表明，施用有机物料结合松动白浆层，不仅改善耕层土壤的物理、化学及生物性状，而且可使白浆层的不良性状得到改善，有机碳及重组碳含量增加，追加复合量提高０．３４％～０．７７％，生物活性明显提高。 Field experiment on typical white soil in Sanjiang Plain. The results showed that the application of organic material combined with loose white pulp layer not only improved physical, chemical and biological properties of topsoil, but also improved the bad traits of white pulp layer, increased the content of organic carbon and recombinant carbon, and increased the amount of additional compound .34% ~ 0.77%, biological activity was significantly improved.
