摘要
本文对 OTC-1型开顶式气室的结构和性能与国内外同类气室进行了比较,结果表明,由于OTC-1型开顶式气室通风方式的明显改进,使得气室内 CO_2浓度分布更为均匀,气室之间气象要素差异较小且更接近于自然农田,试验期间 CO_2浓度控制稳定。
The structue and function comparsion between OTC—1 open top chamber with the similar one in home and overseas shows that,because the vantilate way of OTC—1 open top chamber is remarkably improved,makes the distribution of CO_2 concentration in chamber more uniform,and the difference of meteorological elements between different chambers de- creasing,and more similar to the natural farmland.The CO_2 concentration control is steady during the experimental period
