通过US350环境传感器监测了北京地区设施西瓜全生育期的环境因子(包括温度、光照强度、空气相对湿度和CO_2浓度)等环境指标。结果表明:北京地区日光温室西瓜生育期内平均空气温度变化范围10.67~29.95℃,平均土壤温度变化范围16.92~35.10℃,平均光照强度268.37~13 842.60lx,平均空气相对湿度变化范围52.40%~94.26%,平均CO_2浓度变化范围455~631mL·m~(-3);北京地区春大棚设施西甜瓜生育期内平均空气温度变化范围14.05~29.84℃,平均土壤温度变化范围17.47~28.12℃,平均光照强度55.80~12 858.64lx,平均土壤水分含量变化范围18.19%~34.56%,平均空气相对湿度变化范围20.72%~96.26%,平均CO_2浓度变化范围351~544mL·m~(-3)。
The environmental indicators (including temperature, light intensity, air relative humidity and CO 2 concentration) of watermelon during the whole growth period of facilities in Beijing were monitored by the US350 environmental sensor. The results showed that the mean air temperature ranged from 10.67 to 29.95 ℃ and the average soil temperature ranged from 16.92 to 35.10 ℃ and the average light intensity ranged from 268.37 to 13 842.60 lx and the average relative air humidity ranged from 52.40% to 94.26 %, Average CO 2 concentration ranged from 455 to 631 mL · m -3. The average air temperature range of 14.05 ~ 29.84 ℃ and average soil temperature range of 17.47 ~ 28.12 ℃ during the growth period of melon in spring canopy facilities in Beijing were average light The average soil moisture content ranged from 18.19% to 34.56%. The average relative air humidity ranged from 20.72% to 96.26%. The average CO_2 concentration ranged from 351 to 544 mL · m -3.
