3，The acidity of the foliar fertilizer should be appropriate
Nutrient elements have different existing states under different pH levels. To maximize the benefits of fertilizers, there must be a suitable acidity range. Generally, the pH value is required to be 5-8, and the pH value is too high or too low, in addition to affecting the absorption of nutrients, it will also cause harm to crops.
Add additives
When the pilot uses the plant protection drone to spray the fertilizer solution on the leaves, appropriate additives can be added to improve the adhesion of the fertilizer solution on the plant leaves and promote the absorption of fertilizer.
Late spraying
After the plant protection drone is sprayed, the cleaning tank and the residual fertilizer in the spraying device must be properly treated. The residual fertilizer in the piping must also be safely treated. The medicine tank, piping, nozzles, etc. need to be specially cleaned
