当前全球性大气CO_2浓度的提高可能导致作物产量和水分利用的改变。在生长室里进行试验以确定提高CO_2浓度并结合不同土壤含水量对玉米生长、产量、蒸腾作用和用水效率的影响。共三种CO_2浓度(350～360、600～650和850～900微升/升),每种CO_2浓
The current global atmospheric CO 2 concentration increase may lead to changes in crop yield and water use. Experiments were conducted in the growth chamber to determine the effects of increasing CO 2 concentration and combining different soil moisture levels on maize growth, yield, transpiration and water use efficiency. Three CO 2 concentrations (350-360, 600-650 and 850-900 μl / L) were obtained. Each CO 2 concentration
