In the spraying of pesticides and fertilizers, the surface tension will affect the spreading degree of liquid on the leaf surface. If the contact area between liquid and leaves is small, the absorption effect of pesticides or fertilizers by plants may be poor. In order to improve this situation, some surfactants can be used together, such as "not afraid of rain" by Shanghai Yongtong, which can effectively reduce the surface tension of liquid medicine or water-soluble fertilizer solution, make the liquid spread on the leaves better, and help plants absorb pesticides and fertilizers more effectively.
In addition, surface tension is also used in the design of irrigation system. The surface tension coefficient of liquid will affect the flow rate of liquid in water pipe and the discharge speed of nozzle. Engineers will choose the appropriate liquid surface tension coefficient according to the actual situation to achieve the best irrigation and spraying effect.
