| 中文摘要: |
| 对海南主栽芒果品种台农和金煌芒的叶片养分的变化动态进行了分析。结果表明，相同栽培模式下，芒果叶片养分含量在不同品种、不同生长发育阶段和不同物候期之间存在显著的差异，但总体规律为：Ca＞N＞K＞Mg＞P＞Mn＞Fe＞Cu＞Zn。营养生长期间，不同月份芒果叶片中N、P、K、Mg含量基本保持在同一水平上；生殖生长期间，养分从叶片转移至花芽中，叶片养分明显下降。对于大量元素N、P、K、Mg而言，8月份至12月份叶片养分波动较小，因此10月份芒果的叶片可以作为叶片营养诊断的采样时间。 |

| Monthly-dynamics of nutrient contents in the leaves were analyzed in Tainong and Jinhuang Mango varieties as the main cultivars in Hannan. The results showed that in the same cultivation mode, there were significant differences in mango leaf nutrient contents in different varieties, different developmental stages and in different phenological phases, but the overall rule was Ca> N> K> Mg> P> Mn> Fe> Cu> Zn. In vegetative stage, the content of N, P, K or Mg in leaves was at the same level in different month, while in reproductive stage, these nutrients were transferred from leaves to flower buds and obviously decreased in leaves. The contents of N, P, K and Mg less changed in leaves from August to December, and October is suggested as the sampling time for Mango leaf nutrient diagnosis. |
