根据2010年GPS定位测土试验结果,利用经典统计学与地统计学等方法,分析了农场尺度有机质、碱解氮、有效磷、速效钾、pH与有效硫等土壤养分指标的空间变异特征,并进行了上述指标的地理制图,旨在阐明研究区复兴圩农场土壤养分的空间分布规律,为该农场实行作物精确施肥策略、提升作物生产能力与经济效益等提供理论参考。
According to the results of soil testing using GPS in 2010, the paper analyzed the spatial variability characteristics of the soil nutrient index such as organic matter, alkali-hydrolyzable nitrogen, available phosphorous, available potassium, pH value and effective sulfur on the farm scale by the methods of classical statistics and geostatistics, and made geographic cartography based on the above indicators. The paper aimed at clarifying the regulation of the spatial distribution of the soil nutrients in the study area of Fuxingwei farm, and providing theoretical reference for the farm to implement precise fertilization strategy of crops and improve crop production capacity and economic benefits.
