摘　　要：分析了山东省棕壤、褐土、潮土、砂姜黑土和盐碱土果园的土壤理化性状,取样测定了上述土壤红富士苹果的果实含钙量。结果表明,除盐碱土外,土壤有效性钙含量高低顺序是:砂姜黑土>褐土>潮土>棕壤;果实中含钙量高低的排序同上。土壤交换性钙含量与果实含钙量呈显著正相关。栽培红富士苹果的土壤Ca/Mg比值为8-16、N/Ca比值9-18较适宜。棕壤栽培红富士苹果应增施钙肥,并减少氮素化肥的施用量,以降低N/Ca比值。Analyses of soil physico - chemical properties and calcium levels in ' Red Fuji' apples as well as in various soil types cultivated ascertained that excepting salinized soil , the calcium contents both in apples and cultured soil types were gravel black soil > cinnamon soil > fluvio - aquic soil > brown forest soil. The calcium content in fruit was positively correlated with exchangeable calcium in soil. The specific values of 8 - 16 Ca/Mg and 9 - 18 N/Ca in soil were suitable to ' Red Fuji' apple. ' Red Fuji' apple trees grown on cinnamon soil should be fertilized with more calcium but less nitrogen.
