- W2348754862 abstract "The objective of this study was to accelerate the extensive application and production of sweet potato Guifen No.2,known for its high yield and energy type,and to explore the high-yield culture technique.The relevant densities and different fertilizers of nitrogen(N),phosphate(P),and potassium(K) were tested in field experiments using 4-factors-5-levels-twice-versatile regressive rotary compound design(half implementation).The regression model between densities and different fertilizers of nitrogen(N),phosphate(P),and potassium(K) was consequently established.From the measured results,the effects of fertilizer and density on the yield of sweet potato was NPdensityK.The optimal combination for the maximum theoretical yield of 32685.60 kg·hm-2 of sweet potato was the density of 53835-55515 zhu·hm-2,N content of 116.85-125.10kg·hm-2,P2O5 content of 59.85-64.35kg·hm-2,and K2O content of 156.60-173.40 kg·hm-2.There was a significant positive correlation between the yield of sweet potato and the different groups of density and fertilizer.According to the regression model,the relation between yield and density and N,P,K was expounded to provide theoretical basis for the large-area growth of this new sweet potato cultivar Guifen No.2." @default.
