大量的研究证实,作物的光呼吸会无益地消耗光合作用的中间产物乙醇酸,使光合效率明显下降;光呼吸抑制剂亚硫酸氢钠,在植物体内可转化成羟基磺酸,对乙醇酸氧化酶有抑制作用。经我们试用,普遍反应良好。1983年全县喷施亚硫酸氢钠的杂交晚稻共900亩,平均亩产821.4斤,比未喷的亩增75.3斤,增产10.1％。为了探索这种药剂在不同时期、不同用量和不同使用方法的效果,以找出最佳的使用技术,我们在示范的同时进行了多点对比试验。 A large number of studies have confirmed that the photosynthesis of crops, photosynthetic light consumption will be beneficial to consume the intermediate product of glycolic acid, so that photosynthetic efficiency decreased significantly; photo respiration inhibitor sodium bisulfite, can be transformed into hydroxy acid in plants, glycolic acid oxidation Enzyme inhibition. After our trial, the general response is good. In 1983 the county spraying sodium bisulfate hybrid late rice a total of 900 acres, the average yield of 821.4 kg, mu than the increase of 75.3 pounds mu, an increase of 10.1%. In order to explore the effect of different dosage, different dosage and different methods of using this medicine in order to find out the best using technique, we carried out multi-point comparison test while demonstrating it.
