摘　　要：根据自行设计的ＯＴＣ－１型开顶式气室及连续３年试验资料，在评述该套设备性能的基础上，分析了ＣＯ２浓度倍增对４种作物生长发育和产量的影响。结果表明：ＣＯ２浓度倍增，作物发育进程加快，株高增加，经济产量和生物产量增长明显，且Ｃ３作物的增长幅度大于Ｃ４作物；冬小麦、棉花品质呈良性变化，玉米品质可能有所下降，大豆品质变化不明显。According to OTC 1 Open top chamber designed by ourselves and experimental data of succssive 3 years,we analysed the effects of CO 2 concentration at double levels of natural condition on growth,development and yields of 4 crops based on discussing the physical performance of the equipment.The results showed that an increasing CO 2 concentration accelerated the course of crops growth,increased the height of plant,economical yields and biomass production greatly,and the increasing range of C 3 crops was greater than that of C 4 crops;The quality of winter wheat and cotton seemly have positive effect,on the contrary,the quality of crn seemly has negative effect,the change of soybean quality wasnt obvious.
