Effect on Physical-chemical Properties of Planosol with Subsoil Fertilizing

KUANG En-jun1,2,LIU Feng3,GUO Wen-yi4(1.Plant Science and Technology College of Heilongjiang August First Land Reclamation University,Daqing 163319;2 Soil and Fertilizer and Environment Resource Institute of Heilongjiang Academy of Agricultural Sciences,The Key Laboratory of Soil Environment and Plant Nutrition of Heilongjiang Province,Harbin 150086;3.Science Research Department of Heilongjiang Academy of Agricultural Sciences,Harbin 150086;4.Army of 39012 of Xianghua Village in Keshan County,Qiqihaer 161000)  
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 physical-chemical 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.
