山核桃果实品质与土壤性质的相关分析

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.

Study on Correlation between Soil Property and Fruit Quality of Carya cathayensis

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.
