| 摘 要： | 试验于2002年采用心土培肥犁进行大田作业处理,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。4年后调查土壤理化性质,结果表明：心土混层改土区与对照区相比20-35 cm土层土壤固相比例降低,液气比例有所上升;孔隙度20-50 cm机械处理区平均比对照高5.00%-6.68%,说明机械处理4年后改土效果仍然十分明显。白浆土心土有效磷含量随施磷量的增加而增加,心土施钙提高土壤pH。连续3年产量调查结果,磷和钙配施增产效果最好,比对照平均增产20.27%。 |

| Abstract: | The experiment used the subsoil fertilizing plough mixed Aw layer with horizon B and put some fertilizers such as phosphate and calcium into the mixed layers in 2002. The results which investigated the physicalchemical properties after 4 years showed that the solid phase of treatment was lower than uncontrolled in 20-35cm layers,liquid and air phases of treatment were higher than uncontrolled; and the average porosity of treatment was larger than that of uncontrolled by 5.00%-6.68%. So after 4 years,the effect was still obviously. The available P content of planosol subsoil increased along with the quantity of phosphate we put in. The subsoil was executed Ca to enhance the soil pH. The yield showed that Subsoil-fertilizer with Ca and P made the effect of production increasing to be best,higher than uncontrolled by 20.27% on average in 3 years. |
