Abstract：To ensure that fertilizers are fully utilized during crop growth and that the soil receives appropriate nutrients,the uniformity of fertilizer application cannot be overlooked.Proportional fertigation pumps and Venturi injectors are commonly used fertilization devices in agricultural irrigation systems.Proportional fertigation pumps can precisely control the concentration and amount of fertilizer applied,ensuring stable and reliable growth for crops with strict fertilization requirements.Venturi injectors,on the other hand,operate without the need for external energy sources,making them unaffected by energy supply limitations during use.They are simple to operate,reducing user operational difficulty and the likelihood of errors.A uniformity test was conducted to compare the two fertilization methods:Venturi injector fertilization and proportional fertigation pump fertilization.The results showed that the uniformity of fertilization using a proportional fertigation pump was superior to that of the Venturi injector.
