(三)红外线CO_2分析仪和配套装置果树是有生命的植物。在应用红外线CO_2分析仪测定其光合作用特性时,必须控制影响果树生理活动的各种环境因素,如光照强度、温度、湿度、气流速度以及空气中的CO_2浓度和O_2浓度等,使测定条件尽量接近自然状况,并要使测定条件保持
(C) infrared CO_2 analyzer and supporting devices Fruit trees are living plants. In the application of infrared CO_2 analyzer to measure its photosynthetic characteristics, it is necessary to control the various environmental factors that affect the physiological activities of fruit trees, such as light intensity, temperature, humidity, air velocity and CO 2 concentration in the air and O 2 concentration, so that the determination of the conditions as much as possible Close to the natural conditions, and to keep the measurement conditions
