通过对新曹农场不同土壤类型 181个耕层土壤农化样本和 34个定点监测土壤剖面样本的调查分析 ,明确了全场土壤肥力状况有机质含量为 12 6g/kg处在中等偏下水平、全氮含量为 1 1g/kg处于中等偏上水平、碱解氮量为 6 4 95mg/kg处在中等偏下水平、速效磷含量为 15 97mg/kg处于上等水平、速效钾含量为 4 0 2 7mg/kg处在下等水平。分析了土壤肥力演变原因 ,并提出了今后土壤培肥策略和主要措施
Through the investigation and analysis of soil samples of 181 tillage soils from different soil types in Xincao Farm and 34 samples of soil profiles monitored by fixed-point monitoring, it was clarified that the soil organic matter content of the whole soil fertility condition was 12 6g / kg at the middle-lower level Nitrogen content of 1 1 g / kg was in the middle level, the amount of available nitrogen was 6 4 95 mg / kg at the middle level, the available phosphorus was 15 97 mg / kg at the upper level, and the available potassium was 40 2 7mg / kg at the lower level. The reason of soil fertility evolution was analyzed, and the future strategy of soil fertility cultivation and the main measures were put forward
