摘要
CO_2是植物光合作用的重要原料之一,当CO_2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CO_2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CO_2的交换,从而引起设施内的CO_2浓度明显变化,为了进一步探讨和验证CO_2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CO_2气肥,在设施草莓上开展了试验与研究,初步摸索了CO_2的应用技术和施用效果,为设施草莓增施CO_2提高品质、产量提供理论依据。
One of the important raw materials for photosynthesis of plants,when the CO_2 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 CO_2 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 CO_2 exchange,thus cause the CO_2 concentration significantly change of facilities,in order to further investigate and verify the CO_2 air fertilizer applied in facility cultivation in the reaction,we introduced the cylinder liquefied CO_2 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 CO_2 technology and application effect,to improve quality and production facilities strawberry increasing CO_2 provides theory basis.
