我们知道,二氧化碳是植物光合作用过程中不可缺少的原料。如果没有二氧化碳,即使有肥、有水、有光,植物也是不会制造出糖和淀粉的。在二氧化碳短缺的情况下,植物“光合工厂”的原料不足,光合产物的质量就要降低,产量就要下降。 We know that carbon dioxide is an indispensable raw material in photosynthesis of plants. Without carbon dioxide, plants, even with fat, water and light, will not produce sugar and starch. In the case of a shortage of carbon dioxide, the raw material of a plant “photosynthesis plant” is insufficient, the quality of photosynthetic products is reduced, and the yield is reduced.
