The effect of planting density and combined application of Nitrogen with Potassium were studied on the yield of“Datian jinjiang”ginger by 311-A regression design.The results showed that planting density and combined application of Nitrogen with Potassium affected the ginger yield significantly,and any over dosage in application would reduce ginger yield.With the optimization by computer,the results suggested that the high yield would be obtained by density in 4.39 Million4.8 Million plants per hectare and fertilizing N in 151.4~209.5kg·hm-2 combined with K2O in 88.2~117.1kg·hm-2.
