摘　　要：为明晰秸秆生物反应堆技术对冬季日光温室地温、二氧化碳(CO)浓度的影响,在日光温室中应用玉米秸秆行下式秸秆生物反应堆技术,对温室内1—2月份不同时间段CO浓度、15 cm地温进行分析。结果表明,采用行下式秸秆生物反应堆技术与常规栽培相比,1—2月份可平均提高温室15 cm地温1.14~2.82℃,最高可提高3.83℃,提高CO浓度93.57~453.76 mg/m~3,密闭环境最高可提高723.88 mg/m~3。In order to clarify the effect of straw bioreactor technology on the ground temperature and carbon dioxide concentration of solar greenhouses in winter, the corn straw descending straw bioreactor technology was applied in the solar greenhouse, and the effects of carbon dioxide concentration and 15 cm ground temperature were analyzed in different time periods from January to February in the greenhouse. The results show that compared with conventional cultivation, the use of the under-row straw bioreactor technology can increase the average temperature of the greenhouse 15 cm from January to February by 1.14 to 2.82 ℃, the highest can be increased by 3.83 ℃, and the COconcentration can be increased by 93.57 to 453.76 mg/m~3, even up to723.88 mg/m~3 in the closed environment.
