OTC-1型开顶式气室中CO_2对大豆影响的试验结果

The Experiment of the Influences of CO_2 on Soybean in Open Top Chamber OTC-1

利用OTC-1型开顶式气室对大豆进行了长时期不同CO_2浓度处理的接触试验,结果表明:不同CO_2浓度处理对大豆生长发育、生物产量、籽粒产量及叶片光合作用率等影响显著,且均为正效应。

The touch experiment of long time measurement with different CO2 concentration on soybean was made by using open top chamber OTC-1. The result shows that the influences of different CO2 concentration on soybean growth and development, mass and grain yield and photosys-thesis rate are remarkably positive effect.
