摘要
为了进一步提高苹果树的营养状况,便于管理,在山东省栖霞市盛果期果园采样,检测叶片中营养元素的含量,并与标准值比较。结果表明:大量元素中氮、钾肥含量丰富,但磷、钙、镁含量普遍较低;微量元素中铁、锰含量充足,但是硼、铜、锌含量不均匀,部分果园含量低于标准值。
In order to further improve the nutritional status of apple trees and easy to manage,the contents of nutrient elements in leaves of Qixia orchard in Shandong province were measured and compared with the standard values.The results showed that the content of nitrogen and potassium in major elements was rich,but the content of magnesium,calcium,phosphorus were generally low.The content of iron and manganese in trace elements was sufficient,but content of boron,copper and zinc were not uniform,the content of some orchard was lower than the standard value.
