The effects of potassium humate on growth,potassium uptake and utilization efficiency of ginger was studied using a sort of potassium humate fertilizer in pool culture experiment.The result showed that the accumulating amount of dry matter and potassium increased with growth stages,which were well fitted to Logistic equation.Humic acid application increased root vigor and accumulating amount of potassium and dry matter,increased the yield by 8.88% compared with CK.Applying potassium humate promoted the growth of ginger root,increased potassium accumulating rate and amount,increased dry matter accumulating rate and amount.Meanwhile,potassium humate application increased yield by 61.29% and 9.92%,compared with CK and the treatment same application rate of potassium momoxide.Potassium humate application increased agronomic efficiency of potassium fertilizers and recovery efficiency of potassium fertilizers significantly,decreased potassium efficiency for biomass production and potassium harvest index.
