果树进行光合作用的主要原料是二氧化碳和水。在一定范围内,二氧化碳浓度高,光合速率就高,制造和积累的有机营养物质就多,产量就高,而且还能增进果实品质,提高果树的抗性。果树设施栽培,若不能及时给棚室内补充二氧化碳,将严重影响树的光合作用,果树会处于饥饿状态,降低果实产
Photosynthesis of fruit trees the main raw material is carbon dioxide and water. In a certain range, high concentrations of carbon dioxide, photosynthesis rate is high, the production and accumulation of organic nutrients more, yield is high, but also can improve fruit quality, improve fruit tree resistance. Cultivation of fruit trees, if not promptly added to the greenhouse indoor carbon dioxide, will seriously affect the photosynthesis of trees, fruit trees will be in starvation, reduce fruit production
