摘　　要：利用ＯＴＣ－１型开顶式气室对玉米进行了不同ＣＯ_２浓度处理的试验研究，结果表明，ＣＯ_２浓度增加，对玉米发育期和株高几乎没有影响，生物产量和籽粒产量呈上升趋势，籽粒成分变化较为复杂；ＣＯ_２浓度增加，对玉米籽粒粗蛋白、粗纤维和总糖含量的影响呈负效应，对淀粉的影响呈正效应。The effects of increase in CO_2 concentration on corn were studied using OTC-1 open top chamber. The results showed that increase in CO_2 concentration have no effects on corn development stage and height, but increased the biomass and grain yield. With CO_2 concentration increased, negative effects on corn seed rough protein, rough fiber and contents of total carbohydrate were observed but the starch of corn was positively effected.
