【摘要】 测定显示,山核桃适宜生长于微酸性土壤,其果实品质与土壤性质间存在明显的相关关系。其中粗脂肪含量与土壤有效P含量呈显著正相关;粗蛋白含量与土壤有机质、水解N及有效P间具有显著的相关性;K元素含量与土壤有效K呈显著正相关;Na元素含量与土壤pH值呈显著负相关;Ca元素含量与土壤pH值呈极显著负相关;Mg元素含量也与土壤pH值间具有较强的负相关关系。更多还原

【Abstract】 Results indicated that Carya cathayensis growed better in slight acid soil.There was evident relationship between soil property and fruit quality.Coarse fat content had significantly positive relationship with available P;Coarse protein content had significantly positive relationship with organic matter,hydrolyzed N and available P;There was significantly positive relationship between element K content in fruit and available P in soil;Element Na content had significantly negative relationship with pH value;Element Ca had critically negative relationship with pH value;There was also close relationship between element Mg and pH value.更多还原
