Abstract: To study the influence of trace element fertilizer on growth characters and yield of ginger, and explore the optimal fertilization level, the authors carried out a“3414”test (three fertilizer factors, i.e., zinc, boron, and iron, four fertilization levels, fourteen plots) of trace element fertilizer on Anqiu ginger. The results showed that the application of Zn, B, Fe trace element fertilizer had different promoting effects on the growth of ginger, and the yield also increased by 0.5%-15.6%. Through regression equation analysis, the authors found that the optimum fertilizer amount of per hectare of zinc sulfate was 40.1 kg, borax was 25.4 kg and ferrous sulfate was 600.8 kg, and the yield reached 84851 kg/hm2. Under the optimum fertilization, the yield per hectare increased by 5988.5 kg and 7.6%, the output value per hectare increased by RMB 11977, and the input-output ratio was about 1: 27.64, and the economic benefit was the best.
