Abstract

Abstract: In order to clarify potash best installment application period of sweet potato.To study the effect of yield formation,potassium uptake and the influence of soil nutrient change after harvest on different installments K and period of sweet potato.And eight treatments were carried out:CK(No potassium fertilizer),K1(Whole potassium basal applied),K2(Half potassium fertilizer as basal and half as top dressing at 75,100,120 d after transplant)and K3(Whole potassium fertilizer top dressed at 75,100,120 d after transplant) at the year of 2013-2014.The results showed that compared with CK,different ways of K application could significantly improve the biomass,nitrogen and potassium accumulation in and yield of sweet potato.From the point of different K ways and period,compared with the basal application of potash,75 d or 100 d stage K (1/2+1/2 Top dressing) could significantly increase sweet potato 100-160 d biomass,N and K accumulation,N and K use efficiency,2013 yield increased by 13.8%,13.5%,2014 yield increased by 19.1%,18.6%.2013 potassium production efficiency increased by 11.3%,11.5%,2014 potassium production efficiency increased by 18.6%,19.0% respectively;2013 potassium efficiency increased by 6.2,6.3 percentage points,2014 potassium efficiency increased by 9.4,9.6 percentage points;2013 potassium apparent use efficiency increased by 8.2,6.2 percentage points,2014 potassium apparent use efficiency increased by 9.1,7.7 percentage points;under the way of conditions of sweet potato,K basal application should use half potassium fertilizer as basal and half as top dressing,and K application period of 75-100 d after transplanting is advisable.

Key words: Sweet potato, Postponing potassium fertilizer, Potassium absorption
