This study used Liaohong Xiaodou 2 as experimental material, designing 7 different combinations of amino acid soluble fertilizers and auxin to discuss the effects on the growth of adzuki bean. The results showed that the values of stem diameter, number of leaves, dry weight of stem, dry weight of leaves and dry weight of petiole were the highest under the compound treatment of shell calcium magnesium and Xian U Su. The root length, root surface area, root diameter and root volume of the adzuki bean were the largest under the single treatment of Chaonengchongbao. The yield of adzuki bean was the highest under the compound treatment of Shell Calcium Magnesium and Xian U Su.
