近年来,苏联研究家们的工作证明:植物也能通过根部获得二氧化碳。及其同事藉放射性碳素之助指出,根自土壤中吸收的二氧化碳能以很大的速度转运到植物的绿色部分,并在叶中被同化为碳水化合物(光合作用);而且,自根部吸入的二氧化碳佔很大的数量。其他研究家们的材料同样也说明了这一事实。曾以各种植物进行试验,证明通过根以二氧化碳营养植物可以提高植物的收获量。用二氧化碳改善植物的营养能提高叶的光合作用强度。指出,增加叶的光合作用强度首先会影响到植物有经济價值器官 In recent years, the work of Soviet researchers has proved that plants can also get carbon dioxide through the roots. And colleagues showed that carbon dioxide absorbed from the soil can be transported to the green part of the plant at a high rate and assimilated into carbohydrates (photosynthesis) in the leaves by radioactive carbon assists. Furthermore, inhalation from the roots The carbon dioxide accounts for a large amount. The material of other researchers also illustrates this fact. Experiments have been conducted on a variety of plants, demonstrating that the plant’s yield can be increased by rooting the plants with carbon dioxide. Use of carbon dioxide to improve plant nutrition can increase leaf photosynthesis intensity. Pointed out that increasing the photosynthetic intensity of leaves will first affect the plant has an organ of economic value
