| 摘 要： | 研究了反季节莲雾叶片养分周年变化规律,结果表明:莲雾开花对叶片N、P、Mg含量有一定影响,而叶片K、Ca含量受莲雾果实生长发育影响较大;在莲雾幼果期和壮果期喷施叶面肥对于补充叶片Ca、Mg含量有一定效果。并根据不同时期莲雾叶片养分含量的变化提出施肥建议。 |
| 关 键 词： | 莲雾 叶片养分 周年变化 反季节 施肥 |

| Abstract: | In this paper,the annual variation of leaf nutrient of out-of-season wax-apple was studied.Results showed that blooming has some influence on the content of N,P,Mg in wax-apple leaves,and wax-apple fruit growth and development mainly impact K,Ca content.Spraying foliar fertilizer in the period of young fruit and fruit puffness has a certain effect on adding content of Ca and Mg.Then the corresponding recommendations about fertilization were put forward. |
| Keywords: | wax-apple leaf nutrient annual variation out-of-season fertilization |
