目的]研究秸秆生物反应堆技术的应用对温室生态环境因子的影响。方法]以温室为研究对象,栽培试验和室内测定分析相结合,在玉米秸秆反应堆技术应用过程中,对温室生态环境因子地温、气温及湿度进行跟踪观测。结果]秸秆生物反应堆使10cm地温提高1.13～1.52℃,20cm地温提高1.71～2.01℃,棚内温度平均提高1.5～2.3℃;应用秸秆生物反应堆的温室较对照温室夜间湿度下降2%～4%,而对白天的室内湿度影响不明显。结论]秸秆生物反应堆技术,能够明显改善温室的生态环境,解决了日光温室冬季生产地温低的问题,为温室蔬菜增产提供基础保证。

Effect of Straw Bioreactor Landfill Technology on Eco-environmental Factors in Greenhouse

Objective] The research aimed to study the effect of the ecological environment factors of greenhouse by applying straw bioreactor landfill technology. Method] Taking greenhouse as the research object,combining with the cultivation test and indoor measurement analysis,the ecological environment factors during application process of corn straw biology reactor technology were traced and observed,including the ground temperature,air temperature and humidity. Result] The straw bioreactor landfill enhanced 1.13-1.52 ℃ about 10 cm ground temperature and 1.71-2.01 ℃ about 20 cm,and decreased the humidity 2%-4% in the evening,and had no obvious effect on daytime.Conclusion] The straw bioreactor landfill technology can obviously improve ecological environment of greenhouse,and solve the problems of low ground temperature,provide basic guarantee for higher yield of vegetable in greenhouse.
