摘要
工业革命以来,大气中CO2浓度一直在不断升高。所谓CO2的施肥效应是指CO2浓度增加对植物生长的助长作用,CO2浓度上升对粮食作物产量产生的影响将直接关系到气候变化背景下的全球粮食供应安全及人类适应对策。系统主要研究基于PLC的开发平台实现二氧化碳施肥系统的施放时间与浓度的自动控制。
Since the industrial revolution, the concentration of atmospheric CO2has been rising. The so - called CO2fertilization effect refers to the increase of CO2 concentration on plant growth facilitation effect, the increasing of CO2 concentration on grain crop yield impact will be directly related to climate change under the background of the global food supply security and human adaptation strategy. This system mainly studies based on the PLC development platform for the realization of CO2 fertilization system cast time and concentration automatic contro.
