据有关资料报道,作物光合作用形成的有机物质约有30％被光呼吸作用所消耗,目前已探明某些化学物质可以使作物的光呼吸作用减弱,从而减少有机物质的浪费,提高农作物产品的产量。如亚硫酸氢钠、2、3——环氧丙酸、L——谷氨酸等化学制剂施用于小麦、大豆、烟草、菠菜等作物,对光呼吸均有不同程度的抑制作用,取得早熟高产的效果。本试验以价廉、无毒的亚硫酸氢钠为抑制剂,在水稻穗期进行叶面喷施,探讨其增产效果及使用方法,现将初步试验结果报告如下。试验过程 According to relevant information, about 30% of the organic matter formed by photosynthesis of crops is consumed by photorespiration. It has been proved that some chemicals can reduce the photorespiration of crops, thereby reducing the waste of organic matter and increasing the production of crop products Production. Such as sodium bisulfite, 2,3 - epoxypropionic acid, L - glutamic acid and other chemical agents applied to wheat, soybeans, tobacco, spinach and other crops, have different degrees of inhibition of photorespiration, access to premature High yield effect. In this experiment, cheap, non-toxic sodium bisulfite as an inhibitor, the rice heading stage spraying, to explore the effect of increasing production and use, the preliminary test results are reported below. Experimental procedure
