在桃树上喷施不同浓度ＮａＨＳＯ＿３，结果表明，以１００ｍｇ·ｌ￣（－１）效果最佳。于桃树后期落果高峰前３周处理３次，能显著减少后期落果、提高坐果率、促进新梢生长、改善鲜果品质。生理分析显示，此与ＮａＨＳＯ＿３多重生理效应相关。
Spraying different concentrations of NaHSO_3 on the peach tree, the results showed that the best 100mg · l ~ (-1). The treatment of peach tree three times in the first three weeks before the peak of the falling fruit can significantly reduce the late fall fruit, improve the fruit setting rate, promote the growth of new shoots and improve the quality of fresh fruit. Physiological analysis shows that this is related to the multiple physiological effects of NaHSO_3.
