Abstract:: This experiment monitored the environmental indicators which included temperature,lightintensity,relative air humidity and CO₂ concentrations in Beijing area of facilities watermelon in the whole stages.The results showed that in the solar greenhouse,the change range of average air temperature was 10.67-29.95 ℃,change range of soil temperature was 16.92-35.10 ℃,change range of average light intensity was 268.37-13 842.60 lx,change range of air relative humidity was 52.40%-94.26%,change range of average CO₂ concentration was 455-631 mL?m-3.In the greenhouse,the change range of average air temperature was 14.05-29.84 ℃,change range of average soil temperature was 17.47-28.12 ℃,change range of average light intensity was 55.80-12 858.64 lx,change range of average soil moisture content was 18.19%-34.56%,change range of average relative air humidity was 20.72%-96.26%,change range of average CO₂ concentration was 351-544 mL?m^-3.
