亚硫酸氢钠(NaHSO_3)是一种普通的化学药剂,自本世纪六十年代中揭示其对光合作用的光呼吸作用后,被称为光呼吸抑制剂。但能否应用于大田生产,国外至今尚未见报道。我们于1978—1981年开展亚硫酸氢钠应用研究工作表明;水稻穗期喷施200ppm 亚硫酸氢钠能促进籽粒饱满、降低空秕率、提高千粒重,具有早熟增产的作用。1982年在安徽省科委领导和支持下,于宣城地区、芜湖市以及巢县水稻科学实验点上进行了亚硫酸氢钠大面积示范应用。
Sodium bisulfite (NaHSO 3) is a common chemical agent that has been called a photorespiratory inhibitor since its discovery of its photosynthetic photorespiration since the 1960s. However, whether it can be applied to field production has not been reported abroad. Our research work on sodium bisulphite application in 1978-1981 showed that spraying 200ppm sodium bisulfate at the heading stage promoted full grain, reduced empty rate, increased 1000-grain weight, and had the effect of increasing yield early. In 1982, under the leadership and support of Science and Technology Commission of Anhui Province, a large area demonstration application of sodium bisulfite was carried out in Xuancheng area, Wuhu city and Chao county rice scientific experiment site.
