| 摘 要： | 结合施肥实践阐述了平衡施肥原理中静态的横向平衡和动态的纵向平衡概念,并提出具有纵向平衡特点的速度复合型控释肥,其养分释放速度能与作物的养分需求基本一致,可显著提高肥料利用率和作物产量。 |
| 关 键 词： | 平衡施肥 肥料利用率 控释肥料 横向平衡 纵向平衡 |

| Abstract: | The concepts of balanced fertilization linking up applied fertilizer practices are explicated, which include static and roworiented , as well as dynamic and columnoriented balanced fertilization. The controlled release fertilizer of the ratecompound type with columnoriented characteristic is further discussed. The nutrient releasing rates of the fertilizer synchronizes approximately with the absorption by crop and it could increase fertilizer use efficiency and crop yield significantly |
| Keywords: | balanced fertilization fertilizer use efficiency controlled release fertilizer roworiented balance columnoriented balance |
