| 摘 要： | 设计了基于STM32单片机的水肥调节系统，该系统通过控制不同电磁阀开度实现不同元素水肥配比的调节。以生菜为例研究在其他元素水肥配比正常浓度的情况下，调节控制钾肥浓度的电磁阀开度，使得不同生菜对照组在具有不同钾肥浓度下生长，对比研究不同钾肥浓度与生菜叶片面积和植株高度的关系，从而得到电磁阀开度调整策略，实现水肥配比的精准调节。

| Abstract: | A water and fertilizer regulating system based on STM32 single chip microcomputer is designed, which can adjust the water and fertilizer ratio of different elements by controlling the opening of different solenoid valves. Taking lettuce as an example, under the condition of normal concentration of water-fertilizer ratio of other elements, the electromagnetic valve opened to control the concentration of potassium fertilizer, so that different control groups of lettuce could grow under different concentration of potassium fertilizer, the relationship between leaf area and plant height of lettuce and different potassium concentration was studied. Thus, the adjusting strategy of the electromagnetic valve opening can be obtained, and the precise adjustment of water-fertilizer ratio can be realized. |

| Keywords: | Stm32 water-fertilizer ratio lettuce potassium concentration precise regulation |
