摘　　要：采用心土培肥犁将白浆土的白浆层和淀积层混拌,并向混拌层施入改土物料钙肥和磷肥。试验结果显示:心土培肥的增产效果稳定,磷培肥区比对照区增产17.4%～26.4%,钙培肥区比对照区增产9.2%～16.3%。在心土混层耕基础上进行心土培肥,磷培肥的增产效果明显。对白浆土进行心土培肥,改善了其障碍层次,从而达到培肥土壤的目的。Through subsoil amendment by mixing Aw and B horizons with plough and at the same time, some fertilizers such as phosphate and calcium were applied into the mixed layers. The results showed that the crops yield was increased obviously by subsoil amendment. Compared with untreated control, yield increased by 17.4-26.4%, 9.2-16.3% respectively, after the application of phosphorus and calcium. Base on the subsoil plough, the increasing effect was obvious due to the breaking of obstacle horizons of Shajiang soil.
