Abstract To explore the effect of different pipeline layouts in fertilizer applicator on Venturi injectors performance, multi-channel fertilizer applicators were tested with five same Venturi injectors for diffe-rent main pipe pressure and two pipeline layout modes. The results showed that compared with bypass-pushing-fertilizer pipeline, the numbers of Venturi injector channels with high efficiency can be dominated by bypass-pulling-fertilizer pipeline, up to a maximum of six. What′s more, bypass-pulling-fertilizer pipeline layout mode can meet accurate ratio fertilization of more various nutrient medium si-multaneously, and it can be applied to drip irrigation system that has a wider range of main pipe pressure compared with bypass-pushing-fertilizer mode. When the number of channels is less than 3, the ave-rage suction amount of single channel for bypass-pushing-fertilizer mode decreases with the increase of pressure, however, the average suction amount of single channel for bypass-pulling-ferti-lizer mode could keep stable. Under the same number of channels, the total suction volume flow and proportion of fertilizer injection for bypass-pulling-fertilizer mode are obviously higher than those for bypass-pushing-fertilizer mode, and ″three channels+ bypass-pulling-fertilizer mode″ can be recommended as an optimal pipeline layout mode for fertilizer applicator.
