秸秆生物反应堆对温室气温和二氧化碳浓度的影响

Effect of Straw Bioreactor Landfill on Temperature and CO_2 Concentration in Greenhouse

[目的]研究秸秆生物反应堆技术的应用对茄子温室内气温和二氧化碳浓度的影响。[方法]以茄子温室为研究对象,通过栽培试验和室内测定分析方法相结合,对玉米秸秆反应堆技术应用过程中的温室内外二氧化碳浓度进行跟踪观测。[结果]秸秆生物反应堆对棚内气温有明显的提高,平均提高1.5～2.3℃,最高可以提高温室温度4℃。应用秸秆生物反应堆可以明显提高棚内二氧化碳浓度。[结论]秸秆生物反应堆技术能够明显改善温室的生态环境,解决日光温室CO2不足的矛盾,为温室蔬菜增产提供基础保证。

[Objective]The aim was to study the effect of applying straw biology reactor technology on temperature and carbon dioxide concentration of eggplant greenhouse.[Method]With eggplant greenhouse as study objective,the carbon dioxide concentration variation was observed during application process of corn straw biology reactor technology in eggplant greenhouse,by combining with the cultivation test and indoor measurement analysis.[Result]The results showed that straw bioreactor landfill obviously improve temperature 1.5-2.3 ℃,the highest could be increased 4 ℃.And the applying of straw bioreactor landfill could also increase indoor carbon dioxide concentration.[Conclusion]The straw biology reactor technology can improve ecological environment of greenhouse obviously and solve the problem of low CO2 concentration,which will provide basis for higher yield of greenhouse vegetable.
