Abstract
Effect of different varieties,planting density and fertilization method on the yield of sweet potato was studied by using orthogonal design method.The results showed that: varieties were the main factor affecting sweet potato yield,then cultural density and the fertilization method was a secondary factor.Meanwhile,the maximum tuber yield could be obtained when Longshu1 and Jinshan57 were chosen and planting density,fertilization rates of N,P2O5 and K2O were 4000 plant/667m2(60,000 plant/hm2),11.5 kg/667m2(172.5 kg/hm2),53 kg/667m2(795 kg/hm2) and 15 kg/667m2(225 kg/hm2) respectively.关键词
