亚硫酸氢钠(NaHSO_3)是绿色植物光呼吸抑制剂。在农作物上应用亚硫酸氢钠,主要是抑制光呼吸作用,增加光合产物的积累,以达到提高产量的目的。1978—1982年来,我们在水稻抽穗期喷施亚硫酸氢钠,适当抑制一部分光呼吸,提高光合效率,使产量提高10％左右。同时,我们根据水稻品种不同,其光呼吸强度有差异的特性,在研究亚硫酸氢钠对各品种均有不同程度增产效果基础上,进行了品种间的比较试验和分析。结果发现,亚硫酸氢钠对不同类型或不同品
Sodium bisulfite (NaHSO_3) is a green plant photorespiration inhibitor. Application of sodium bisulfite in crops, mainly inhibition of photorespiration, increase the accumulation of photosynthetic products, in order to achieve the purpose of increasing production. From 1978 to 1982, we sprayed sodium bisulfite during rice heading stage to restrain some light respiration properly and increase the photosynthetic efficiency so that the yield could be increased by about 10%. In the meantime, according to the differences of rice varieties, their photosynthetic respiration intensity was different. Based on the study of the effects of sodium bisulfite on the yield of different varieties, the comparative experiments and analyzes were conducted. The results found that sodium bisulfite on different types or different products
