摘要: 根据1980年复兴圩农场全场域第二次土壤普查资料和2000年、2010年GPS定位测土试验数据,研究了复兴圩农场耕作层与剖面土壤有机质、全氮、碱解氮、有效磷、速效钾含量和pH值等的时间维变异特征,以探究农场尺度土壤养分的时间维演变规律,为农场稻麦精确施肥策略的拟订提供理论依据。
关键词: 农场尺度, 土壤养分, 时间维变异
Abstract: Based on the second soil census of whole farm in 1980 and soil testing results using GPS in 2000 and 2010, the paper studied the time dimension variation characteristics of soil organic matter, total nitrogen, alkali-hydrolyzable nitrogen, available phosphorous, available potassium and pH value in the plough layer and profile of Fuxingwei farm, aiming to explore the time dimension variation rules of soil nutrients on the farm scale and provide theory basis for the formulation of precise fertilization strategy on rice and wheat.
Key words: farm scale, soil nutrient, time dimension variation
