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 wasnt obvious.
