通过分析山东省胶东不同地区富士苹果果园土壤养分状况和苹果叶片矿质营养元素含量,探讨苹果叶营养元素含量和土壤矿质元素含量间的关系。结果表明,胶东不同地区富士苹果叶片中大量元素和微量元素的含量存在一定差异,且叶内大量元素基本符合李港丽制定的标准值,而部分微量元素未在正常值范围内;胶东地区土壤p H值在5.47~6.97,适合苹果生长,不同地区土壤中氮、磷、钾和有机质含量有差别,不同土壤深度含量也有一定差异;此外,富士苹果叶中的营养元素含量与其在土壤中的含量间呈现出相关性,其中钾元素在叶片和土壤间呈负相关,氮和磷2种元素在叶片和土壤间都呈现正相关。
By analyzing the soil nutrient status and the contents of mineral nutrient elements in apple orchard in different regions of Shandong Province, the relationship between the content of nutrient elements in apple leaves and the content of mineral elements in soil was discussed. The results showed that there were some differences in the contents of trace elements and trace elements in the leaves of Fuji apple in different areas of Jiaodong. The contents of many elements in leaves were in line with the standard values formulated by Li Gangli and some trace elements were not within the normal range. The p H value ranged from 5.47 to 6.97, which was suitable for the apple growth. The content of nitrogen, phosphorus, potassium and organic matter in different soils differed from each other, and the soil depth also differed to some extent. In addition, The content of potassium showed a negative correlation between leaf and soil, while the contents of nitrogen and phosphorus both showed positive correlation between leaf and soil.
