人工环境在作物种植领域有着显著作用,对大棚蔬菜进行二氧化碳的含量控制可使蔬菜大量增产。文章介绍了二氧化碳的作用机制和通过其含量控制对作物增产的作用。研究结果表明:二氧化碳能促进作物光合作用,增加作物重量、茎长和提高产量;纯质的二氧化碳有着烟气二氧化碳不可以拟的优点;对大多数作物来讲,大棚中二氧化碳最佳浓度为800～1600mg/L;二氧化碳注入方法不仅能用于冬季温室,在春秋季节也有其提高作物产量的经济价值。
The artificial environment has a significant role in the field of crop cultivation. The control of the content of carbon dioxide in greenhouse vegetables can increase the yield of vegetables. The article describes the mechanism of action of carbon dioxide and its role in controlling crop yield through its content control. The results show that: carbon dioxide can promote crop photosynthesis, increase crop weight, stem length and increase yield; pure carbon dioxide has flue gas carbon dioxide can not be the merit; for most crops, the greenhouse carbon dioxide optimum concentration of 800 ~ 1600mg / L; carbon dioxide injection method can not only be used in winter greenhouse, in the spring and autumn also has its economic value to increase crop yield.
