摘要
调查了春玉米、夏玉米生育期间主要生态因子的变化幅度,分析了诸因素对光合蒸腾的影响,利用 Minicuvette-CO_2和 H_2O 测定系统进行了测定条件的测定。并确定了以下两种数学关系:①玉米光合速率与光的关系以及温度和 CO_2对该关系的调节作用;②蒸腾与光合的关系相对湿度对该关系的调节作用。
The changes range and effects of ecological factors on photoysy- nthesis and transpiration was studied under field condition with mincuvette CO_2 and H_2O measuring system during entire growth period,and some mathe- matic models were defined.They were 1,the relationship between photosynthetic rate and photosynthetic activty radaition (PAR) and the affect of temperature and CO_2 on this relatonship,2,the relationship between transpiration and photosynthesis and the effect of relativity humidy (RH) on the relationship.
