通过田间小区试验研究了保水专用肥对甘薯产量和品质的影响。结果表明：保水专用肥可促进甘薯营养器官的生长，增加蔓长和主茎分枝数；与施肥对照相比（ N6 P5 K10），三种保水专用肥处理的鲜薯和薯干产量均表现增产，以保水专用肥1的增产幅度最大，分别比施肥对照增产23．15％和29．33％；保水专用肥可促进前中期可溶性糖的积累和后期向淀粉的转变，收获期三种保水专用肥处理的淀粉含量均高于施肥对照；三种保水专用肥处理的直链淀粉含量均高于空白对照和施肥对照，以保水专用肥1、3的效果佳，其直链淀粉含量分别比对照提高14．57％和15．14％，比施肥对照提高9．07％和9．61％。

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 .
