| 摘 要： | 本研究探讨了赤壳、水涨两个龙眼品种秋梢叶片的常量元素在冬春期间的变化动态。经统计学分析表明:秋梢叶片各常量元素含量均呈显著的消长关系;各元素含量在此期间基本具有一定的消长特点;品种间叶片元素含量的变化规律颇为一致。本试验结果为龙眼营养诊断提供必要的依据。

THE VARIATION OF THE MAJOR NUTRIENT ELEMENTS CONTENTS IN LONGAN LEAF OF AUTUMN SHOOT |
| |
| Abstract: | The present study revealed the winter-spring variation of the major nutrien element contents in the foliage of autumn shoot of two longan cultivars. Statistical analysis showed significant differences from November to March in the amounts of N, P, K, Ca and Mg in the leaves. The variation curves represen~ting the contents of major nutrient elements in longan leaf basically possessed a special change character. Moreover, the variation of the foliage element contents_showed a similar tendency between the two cultivars. Thus, the results of this work may provide the reference for establishing nutritional diagnosis criteri_a of longan leaf. |
