| 摘 要： | 分层施肥是在配方施肥的基础上根据甘薯不同生育期的需肥特点进行养分供给,其增产效果好于配方施肥和普通施肥,高产机理在于通过增加光合面积、提高净同化率、改善光合产物分配来提高经济产量。 |
| 关 键 词： | 分层施肥 甘薯 高产栽培 生理特性 |

| Abstract: | Based on balanced fertilization,separated-layer fertilization could provide nutrients for sweet potato according to the fertilizer requirement in different growth period,so its effect on increasing the root yield was better than balanced fertilization and conventional fertilization.Its high-yielding mechanism was the increase of photosynthetic area and net assimilation rate and the improvement on the regulation of photosynthates. |
| Keywords: | Separated-layer fertilization Sweet potato High-yielding cultivation Physiological characteristics |
