研究了在盆栽条件下胶囊型花卉肥和粉状花卉肥氮、磷、钾释放规律，结果表明，粉状花卉肥氮、磷、钾的释放周期较短，胶囊灌装后氮、磷、钾释放周期相对较长，即胶囊对氮、磷、钾的释放有延缓作用，有利于花卉的吸收利用，减少了养分损失。

The release rule of nitrogen， phosphorus， potassium of capsule and powder flower fertilizer is studied in pot cultured， the result shows that nitrogen， phosphorus， potassium releasing time of capsule fertilizer is longer than powder fertilizer. We can conclude that the capsule has the delayed action for nitrogen， phosphorus， potassium releasing to reduce the nutrient losses， this is benefit for flower to use nutrients， reduce the loss of nutrients.
