农场尺度土壤养分空间变异研究--以复兴圩农场为例
Study on Spatial Variability of Soil Nutrients on the Farm Scale
摘要
Abstract
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 ef-fective 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 Fux-ingwei farm, and providing theoretical reference for the farm to implement precise fertilization strategy of crops and improve crop pro-duction capacity and economic benefits.关键词
