摘　　要：以微机为中枢，配以先进的温度、照度、ＣＯ２红外传感器及相关的控制器件，对工厂化育苗车间（塑料大棚）的温度、照度、ＣＯ２浓度等物理量实施远距离自动监测和控制，并对采集的实验数据进行及时的处理、分析，作出相应的变化曲线，用于指导工厂化容器育苗施放ＣＯ２气肥技术的实施。多年实验表明，应用此项技术可根据天气条件，精细控制育苗车间的ＣＯ２浓度，提高针叶树生物量的０．２～０．５倍。Using a computer and data sampling system with temperature, light intensity and CO2 concentration sensor, the temperature, light intensity and CO2 concentration in a greenhouse was measure, recorded and real time treated. Based on the result of long time research, CO2 concentra- tion was precisely and optimally controlled by this system according to the weather conditions. As the result, the growth of needle leaves was increased by 20% to 50%. This paper will describe the whole computer control system in a detail.
