Abstract:

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 leaf mineral 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 the mineral elements, the content of soluble sugar and titratable acid in leaf and fruit and the mineral elements in soil were significant. The correlation of fruit shape index and the 13 kinds of mineral 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.
