Q-Box便携土壤呼吸测量系统（Q-Box SR1LP Soil Respiration PacKage ） The Q-Box SR1LP Soil Respiration Package provides the user with all of the materials required to measure soil respiration using an open-flow gas exchange system when the rate of respiration is high, or as a closed-flow recirculation system when the rate of respiration is low. The Battery Pack and Charger allow the use of the package in the field conditions. Air is pumped at a known flow rate through the soil chamber and sensors. The concentration of CO2 in the air is determined using the Q-S151 CO2 Analyzer. In the open-flow system the difference in CO2 concentration entering the flow through the cuvette holding the soil sample and exiting it is used to calculate the rate of respiration. In a closed-flow system the initial rate of CO2 accumulation in the soil chamber (placed on * of the soil surface) is used to determine the rate of respiration. （Q-box 便携土壤呼吸系统可以作为一个开放的测量方式，也可以选择闭合式的土
