山东省苹果园果实品质指标、叶片营养与土壤营养元素的相关性分析

Correlation Analysis on Fruit Quality and Leaves Nutrition and Soil Nutrient in Apple Orchard of Shandong Province

为了深入了解山东省苹果的生长状况与土壤的相关关系,指导科学施肥,以山东省48个果园的‘红富士’苹果为试材,研究了地上部矿质元素和果实品质与土壤元素的相关性关系,结果表明:叶片中和果实中的矿质元素、可溶性糖和可滴定酸含量与土壤中矿质元素间的相关性都较显著;果形指数与13种指标的相关性都较显著;单果重除与土壤有效硼和全盐含量间的相关性达到显著水平外,与其他11种土壤性状指标间的相关性均达到极显著水平,而且均为正相关;果实光洁度与土壤有效硼的相关性显著,与其他指标的相关性均为极显著;果实硬度与土壤有机质和pH大小呈极显著负相关,与有效钙和有效铁含量间呈显著负相关。果实可溶性固形物含量与土壤全盐的相关性最大,达到极显著水平,相关系数达到0.643。因此,山东省果园应当注重中微量元素肥料的施用。

In order to study the relationship between growth status of apple and Shandong soil condition deeply,and guide fertilization scientifically,＇ Red Fuji ＇ was used as samples,and the correlation among leafmineral elements,fruit quality and soil elements were studied in 48 apple orchards of Shandong Province in this thesis.The results showed that：the correlation among themineral elements,the content of soluble sugar and titratable acid in leaf and fruit and themineral elements in soil were significant.The correlation of fruit shape index and the 13 kinds ofmineral elements were significant.In addition to effective boron,the correlation between individual fruit weight and 11 kinds of soil traits was significant positive level.The correlation of apple smooth finish and soil available boron were significant,furthermore,with other related indexes highly significant.The correlation between fruit hardness and soil organic matter and pH was highly negatively significant,with the effective calcium and iron content reached negatively significant.The correlation between soluble solids content and soil total salt was the biggest,the correlation coefficient reached 0.643.Therefore,people should notice apply more fertilizer of trace elements in Shandong apple orchard.
