【摘要】 CO₂是植物光合作用的重要原料之一,当CO₂浓度不足或较低时,作物的光合作用效率将会减弱,生长,发育迟缓,产量和品质受到影响。根据资料研究表明,一般植物光合作用需要的最佳浓度为0.1%⁰.15%,而大气中CO₂浓度通常只在0.03%左右,不能满足作物生长发育的需要。设施栽培环境结构密闭性往往影响了设施内外CO₂的交换,从而引起设施内的CO₂浓度明显变化,为了进一步探讨和验证CO₂气肥在设施栽培中的肥效反应,我们于2016年冬引进了钢瓶液化CO₂气肥,在设施草莓上开展了试验与研究,初步摸索了CO₂的应用技术和施用效果,为设施草莓增施CO₂提高品质、产量提供理论依据。更多还原

【Abstract】 One of the important raw materials for photosynthesis of plants,when the CO₂ concentration is insufficient or lower,the photosynthesis of crops will weaken,growth,growth retardation,yield and quality will be affected.According to the data,the optimum concentration of plant photosynthesis is 0.1% 0.15%,while CO₂ concentration in the atmosphere is usually only about 0.03%,which can not meet the needs of crop growth and development.Facilities cultivation environment inside and outside the structure often influence in sealing facilities CO₂ exchange,thus cause the CO₂ concentration significantly change of facilities,in order to further investigate and verify the CO₂ air fertilizer applied in facility cultivation in the reaction,we introduced the cylinder liquefied CO₂ air fertilizer in the winter of 2016,on the facility of strawberry has carried out the test and research,preliminary grope for the application of CO₂ technology and application effect,to improve quality and production facilities strawberry increasing CO₂ provides theory basis.更多还原
