Study on the Uniformity of Water and Fertilizer of Hydrodynamic Injection Drip Irrigation Fertilizer Applicator

In order to explore the distribution characteristics of irrigation and fertilization in the drip irrigation fertilizer applicator. In the process of fertilization, photometric colorimetry is used as a method to detect the concentration of fertilizer solution, so as to analyze the uniformity of irrigation and fertilization. The results show that the statistical indicators of the uniformity of fertilization of the fertilizer applicator are above 98%. The irrigation flow and fertilization amount of each emitter are affected by the distance from the emitter to the inlet of the branch pipe and the inlet of the capillary.
