钾肥的肥效高低与施用方法有十分密切关系。现将近几年省化肥试验网进行的和本省一些地区农业生产单位进行钾肥施用技术研究结果整理如下:一、不同肥力稻田施钾的研究:我所在福州郊区典型的贫钾和富钾两块稻田进行施钾试验,其结果见表一。建阳地区农科所在两块不同肥力水平的稻田上进行施钾试验,其结果见表 Fertilizer efficiency and application methods are very closely related. Now in recent years the province fertilizer experiment network carried out in some provinces and the province’s agricultural production units of potassium fertilizer technology research results are summarized as follows: First, the fertility of different fertility paddy fields of potassium: I Fuzhou suburbs typical of two poor-potassium and potassium-rich paddy fields Potassium test, the results in Table 1. Jianyang region where two different levels of fertility in paddy fields for potassium test results are shown in Table
