二氧化碳是植物光合作用的主要原料,也是构成作物产量的物质基础。每种植物都有一个二氧化碳的最低补偿点,当环境中的二氧化碳浓度低于这个最低补偿点时,植物的光合作用就停止,植物即处于一种“饥饿”状态,营养积累减少,入不敷出。若植物长期处于这种状态下,则造成生长衰弱,抗
Carbon dioxide is the main raw material for plant photosynthesis and also the material basis for the crop yield. Each plant has a carbon dioxide minimum compensation point. When the carbon dioxide concentration in the environment is below this minimum compensation point, the plant photosynthesis ceases and the plant is in a state of starvation with reduced nutrient accumulation. If the plant is in this state for a long time, it will result in weak growth and resistance
