人工环境(二氧化碳)在作物增产中的应用

Application of Controlled Environment (CO_2) to Plants Production Increment

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。

Controlled environment has an obvious effect on plants production, and control of carbon dioxide in a greenhouse may be increased production. This paper described the effect of CO2 and controlled concentration on plants production increment. The result showed that CO2 could promote photosynthesis, increase plants weight and height and higher product; pure CO2 has an advantage over smoke CO2 in any case, the lowest concentration CO2 in greenhouse is about 800-1 660mg/L; and injection of CO2 not only could apply to greenhouse in winter but also could promote the production in spring and autumn.
