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.
