光呼吸(Photorespiration)是指植物在光照条件下所进行的吸氧吐碳过程。高光呼吸C_3植物在光合作用的同时,又有1/3以上刚刚合成的有机物质被光呼吸消耗掉,是影响产量、质量的重要因素,现已引起国内外的普遍重视。为探求抑制剂亚硫酸氢钠对西瓜的作用效果,我们于1985年进行了喷施试验。材料与方法试验设在千户寨乡郭寨沟村郭国民的园中,土地平坦,土质重壤,肥力中等,排灌方便。供试品种为“早花”,试剂是天津塘
Photorespiration refers to the process of oxygen and carbon exhaustion carried out by plants under light conditions. High light breathing C_3 plants in photosynthesis at the same time, more than 1/3 of the newly synthesized organic matter is consumed by photorespiration is an important factor affecting the yield, quality, has now attracted widespread attention at home and abroad. In order to explore the effect of inhibitor sodium bisulfite on watermelon, we sprayed it in 1985. Materials and Methods The experiment was conducted in the park of Guo Guomin, Guozhaigou Village, Chiazhai Village, with flat land, heavy earthy soil, moderate fertility and convenient drainage and irrigation. Test varieties for “early flower”, reagent is Tianjin pond
