Abstract：The effects of super absorbent fertilizer on the yield and quality of sweet potato were studied by field plot test .The results showed that super absorbent fertilizer could promote the growth of nutrition or -gan, increase the vine length and branch number .Compared with fertilization control ( N6 P5 K10 ) , the fresh and dry yield of sweet potato under 3 super absorbent fertilizer treatments were all increased .And the increase of super absorbent fertilizer 1 was the highest , which was 23 .15%and 29 .33%higher respectively than those of N6 P5 K10 .Super absorbent fertilizer could promote the accumulation of soluble sugar at early and mid -stage and transformation to starch at late stage .The starch contents of sweet potato under 3 super absorbent fertilizer treatments were all higher than those of N 6 P5 K10 .And the amylose contents were also higher than those of con-trol and N6 P5 K10 .Super absorbent fertilizer 1 and 3 had good effects, and their amylose contents were 14.57%and 15.14% higher respectively than that of control , and 9.07% and 9.61% higher respectively than that of N6 P5 K10 .
