| 摘 要： | 目的]为了解龙眼座果期间树体对养分的需求状况。方法]采摘龙眼座果期间叶片,分析其矿质元素含量,探讨龙眼座果期叶片矿质营养变化规律。结果]龙眼叶片中不同的营养元素在座果期内出现不同的变化规律,在大、中量元素中,N、K的变化最明显,P、Ca、Mg的变化不明显;在微量元素中,Fe的变化最明显,Mn、Cu、Zn、B含量相对稳定。结论]在龙眼座果期间应适当补充N、K、Fe。

| Abstract: | Objective] The purpose of the research on the nutrient need of longan during fruit-setting was explored through the experiment.Method] The content of mineral elements in longan leaf during the fruit-setting was analyzed to discuss the change of mineral nutrition in leaf.Results] There were different variation principles in different mineral nutrients present in longan leaf.In macro and medium elements,the content of N and K was with the most obvious changes and P,Ca and Mg,not significant;and in trace elements,the content of Fe was with the most obvious variation and Mn,Cu,Zn and B,relative stability.Conclusion] It was necessary to properly add N,K and Fe in the period of longan fruit-setting. |
