喷施亚硫酸氢钠促进作物增产,已被实践证明,但人们往往不知道其中的奥妙。作物的生长是光合作用的产物。而光合作用的实质是一个非常复杂的过程,其中有光能吸收的物理过程,光能转化的光化学过程,电子传递过程,以及二氧化碳还原转化酶的生物学过程。人们在长期的生产和科研实践中发现,植物的叶片在光照条件下进行光合作用的同时,也进行呼吸作用,即吸收氧气,放出二氧化碳的过程,这称之为植物的光呼吸。在广泛的植物界中,存在着光合效率差异非常悬殊的两大类植物。农作物中的大豆、小麦、水稻、棉花等,在光照条件下放出二氧化碳进行光呼吸,称为“光呼吸型植物”。这类植物光合效率较低,其光合强度只 Spraying sodium bisulfite to promote crop production has been proved by practice, but people often do not know the secret. Crop growth is a product of photosynthesis. The essence of photosynthesis is a very complicated process, including the physical process of light energy absorption, the photochemical process of light energy conversion, the electron transfer process, and the biological process of carbon dioxide reduction converting enzyme. People in the long-term production and scientific research found that plant leaves under photosynthesis in the light conditions, but also the respiration, that is, the absorption of oxygen, release of carbon dioxide, which is called the plant’s photorespiration. In a wide range of plant kingdoms, there are two broad categories of plants with very poor photosynthetic efficiency. Crops of soybeans, wheat, rice, cotton, etc., in the light of the release of carbon dioxide for light breathing, known as “photorespiration-type plants.” The photosynthetic efficiency of such plants is low, its photosynthetic intensity only
