试验证明,亚硫酸氢钠(NaHSO_3)对C_3作物的光呼吸有明显的抑制作用,光合效率提高10～20％。江苏农学院高煜珠等同志研究,光呼吸对光合作用有双重效应,即降低净光合的消极作用和对光合机理的保护作用。在不同条件下,光呼吸的作用地位也不同,因此,亚硫酸氢钠对C_3作物的抑制是有限度的。超过一定的限度,将影响光合作用的正常进行。花生是C_3作物,光呼吸的作用较强,呼吸消耗较多。为了找出亚硫酸氢钠在花生上喷洒的最佳时期,减少光呼
The results showed that sodium bisulfite (NaHSO_3) significantly inhibited the photorespiration of C_3 crops, and photosynthetic efficiency increased by 10 ~ 20%. Jiangsu Agricultural College, Comrade Gao Yuzhu and other comrades, photorespiration on photosynthesis has a dual effect, that is, to reduce the negative effects of net photosynthesis and photosynthetic mechanism of protection. Under different conditions, the role of photorespiration is also different, therefore, sodium bisulfite inhibition of C_3 crops is limited. More than a certain limit, will affect the normal photosynthesis. Peanut is C_3 crops, the role of light breathing stronger, more respiratory consumption. To find the best time to spray sodium bisulfite on peanuts, reduce the light
