摘要
[目的]为探明环翠区苹果园营养状况。[方法]采用田间果园叶片样品采集和室内分析结合的方法,运用平衡指数法进行营养诊断。[结果]环翠区苹果叶片N、P、K、Ca、Mg含量处于标准范围的比例分别为29.41%、9.80%、0%、10%、100%,其中K和Ca的含量处于低值范围的比例分别为57.84%、80.00%,而N、P的含量处于高值范围的比例分别为70.59%、55.88%。Cu的变异系数为32.32%,是所有测定元素中变异系数最大的元素,其次是Mn和K。运用平衡指数法的诊断结果为:N、P、K、B、Fe、Zn、Mg、Ca、Mn、Cu处于正常范围的比例分别为100%、57.89%、52.63%、94.74%、94.74%、84.21%、100%、78.95%、47.37%、52.63%。[结论]环翠区苹果园磷、钾、锰和铜缺乏比例较大,苹果叶片钾和钙含量处于低值范围的较多。
[ Objective ] The aim was to proven Orchard nutrition in Huaneui district, Shandong Province. [ Method ] The method of field sam- ple collection and laboratory analysis was used, and nutrition diagnosis of the leaves was studied with equilibrium Index method. [ Result] Per- centage of N, P, K, Ca and Mg content of apple leaf in standard range were respectively 29.41% , 9.80% , 0, 10% and 100% , K and Ca content in the lower standard range were 57.84% and 80.00% , but the content of N, P, Mg in higher standard range were 70.59% and 55.88%. Diagnosis by using the method of balance index of N, P, K, B, Fe, Zn, Mg, Ca, Mn, Cu in the normal range of proportion were 100% , 57.89%, 52.63%, 57.89% , 94.74% , 84.21%, 100% , 78.95%, 47.37% and 52.63%. [ Conclusion] Deficiency percentages of phosphorus, potassium, manganese and copper were higher, and the percentage of the content of potassium and calcium in a low range were more in Orchard, Huancui district.
