自1796年，国外学者阐明了植物营养根源是CO2这一问题后，人们就开始了气肥研究．CO2浓度将以2种方式影响作物的代谢、生长发育和产量形成．一种是通过温室效应加热气候，改变降水类型进而影响作物；另一种是浓度变化本身对作物生理过程的影响．1CO2气肥的增产效果文献表明，施 Since 1796, foreign scholars have clarified the root cause of plant nutrition is the issue of CO2, people began to study the gas fertilizer. CO2 concentration affects crop metabolism, growth and yield formation in two ways. One is the warming of the climate through the greenhouse effect, changing the type of precipitation and thus affecting the crop; the other is the effect of the concentration change itself on crop physiology. 1CO2 gas fertilizer yield effect literature shows that Shi
