测定显示,大别山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磷含量呈显著正相关;粗蛋白含量与土壤有机质、水解N及有效磷间具有显著的相关性;钾元素含量与土壤有效钾呈显著正相关;钠元素含量与土壤pH值呈显著负相关;钙元素含量与土壤pH值呈极显著负相关;镁元素含量也与土壤pH值间具有较强的负相关关系。
The results indicated that Carya dabieshanensis growed better in slight acid soil, and there was evident relationship between soil property and fruit quality. The content of crude fat had significantly positive relationship with the content of available phosphorus in soil; the content of crude protein had significantly relationship with organic matter, hydrolyzable nitrogen and available phosphorus ; there was significantly positive relationship between the content of potassium in fruit and available phosphorus in soil; the content of sodium had significantly negative relationship with the pH value of soil ; the content of calcium had critically negative relationship with the pH value of soil; there was also close negative relationship between the content of magnesium and the pH value of soil.
