Abstract: Taking the 12-year-old Red Fuji apple(Malus domestica Borkh. cv. Red Fuji) trees in the full fruit period as test materials, 1, 2, 3, 4, 5 mmol/L of Na2SO3 solution were sprayed on the leaves and fruit surfaces(respectively recorded as Ⅰ, Ⅱ, Ⅲ, Ⅳ, Ⅴ group), with fog liquid water as control. The experiment demonstrated that the exterior and internal quality of the fruits of treated groups were improved to different degrees compared with the control. Except for group V, the growth, yields, high quality fraction and total output value of the other groups were increased. The total output value(rate) of group Ⅲ was increased by 168.40(12.2%), 68.70(5.0%), 177.20(12.8%), 288.20(20.8%), 279.70(20.2%) CNY than group Ⅰ, Ⅱ, Ⅳ, Ⅴ and CK, respectively. The difference was significant. The results showed that Na2SO3 had similar effects with NaHSO3 and KHSO3 on Red Fuji apples, and the optimal spraying concentration was 3 mmol/L.
