摘　　要：为观察不同气候条件下，亚硫酸氢盐对红富士叶片光合色素含量和果实生长量的影响，以10～11年生盛果期红富士苹果树为试材，分别在高温、多日照干旱年份和低温、寡日照多雨年份进行外源喷施5 mmol＆#183; L-1的NaHSO3和KHSO3溶液的试验，以喷清水为对照。结果显示，无论是高温、多日照干旱年份还是低温、寡日照多雨年份，两种亚硫酸氢盐处理组叶片的光合色素含量和果实生长量均显著高于同期对照组，且KH-SO3的作用效果优于NaHSO3；相同处理组间，低温、寡日照多雨年份的光合色素含量显著高于高温、多日照干旱年份，而果实生长量却明显比干旱、高温、多日照年份低。Spraying 5 mmol＆#183; L-1 NaHSO3 and KHSO3 on the 10-11 a Red Fuji apple trees was carried out under high temperature, strong sunlight and arid condition or low temperature , poor sunlight and rainy condition to investigate the effect of bisulfate on the photosynthetic pigments content and fruit growth of Red Fuji apple , and water was used as the control.The results showed that the experimental groups were superior to the control significantly , and the effect of KHSO3 was better than that of NaHSO 3 .It was also concluded that the photosynthetic pigments under the low temperature, poor sunlight and rainy condition were higher than that under high temperature , strong sunlight and arid condition in both experimental group and the control obviously , but the fruit growth changed to the contrary .
