摘要: 为了测定不同冬枣园(高产园和低产园)各个物候期叶片中营养元素含量的动态变化,以天津2个冬枣园的冬枣为试材,探究冬枣物候期营养元素动态变化趋势。结果表明,叶片中氮、磷元素含量呈降低趋势,钾、钙、镁、铁、锰、硼元素含量呈上升趋势,且高产园除镁、锰以外营养元素年平均含量均高于低产园。研究结果表明,在冬枣园的生产管理中,可以通过叶片喷施的方法补充营养,为冬枣的营养诊断和合理施肥提供理论依据。

关键词: 冬枣, 叶片, 物候期, 营养元素, 动态

Abstract: In order to determine the dynamic changes of nutrient element content in leaves of different winter jujube orchards(high-yield orchard and low-yield orchard)in each phenological period, and the dynamic trend of nutrient elements in Tianjin Dongzao in each phenological period was explored. The results showed that the contents of nitrogen and phosphorus in the leaves showed a decreasing trend, and the contents of potassium, calcium, magnesium, iron, manganese, and boron showed an increasing trend. The annual average content of nutrient elements except magnesium and manganese in high-yield orchards was higher than that in low-yield orchards. The research results showed that in the production and management of winter jujube orchards, nutrient can be supplemented by spraying leaves, which provide theoretical basis for the nutritional diagnosis and reasonable fertilization of winter jujube.

Key words: Dongzao, leaf, phenological period, nutrient element, dynamic
