【摘要】 由于缺乏理论指导,我国目前的CO2供给方式不能很好解决温室CO2匮乏的问题。本文立足我国农业现状,提出了碳酸氢铵控释CO2供给新技术,并对控释效果进行了模拟计算。结果证明,该技术可使温室内在作物光合作用旺盛时段CO2浓度达到800μmol/mol以上,可以较好满足温室CO2施肥要求。更多还原

【Abstract】 Due to lack of theoretical guidance,the present CO₂ supply mode in China cannot very well solve the problem of CO₂ shortage in the greenhouse.Based on the present agricultural situation in China,this article offers a new technology for the controlled CO₂ supply from ammonium bicarbonate,and analog computation of the result of controlled release is carried out.The results prove that this technology can bring the CO₂ concentration to over 800 μmol/mol at the peak stage of photosynthesis of the crops in the greenhouse and well satisfy the requirement of CO₂ application in the greenhouse.更多还原
