【摘要】 以"四位一体"农村能源生态模式为研究对象,分析了12～1月该模式的保温效果。试验结果表明:晴天时,室内气温增加明显,最快时每小时增温5～9℃;阴天时,清晨室内最低气温在-1℃左右,低于一般作物生长温度的下限;通过积温分析,1月份活动积温0℃为299.7度,10℃为199.7度,有效积温0℃为299.7度,10℃只有49.7度;温室内地温最高可达23℃,最低为5℃;10 cm深的平均地温为11℃,30 cm深的平均地温为13℃,10～30 cm深的地温介于上述温度之间;温室内空气相对湿度均在65%以上,在晴天,室内空气湿度能维持在80%以上。通过研究分析,该温室在此时期适合种植耐寒作物。更多还原

【Abstract】 In this paper,"Four in One" ecological model of rural energy is taked as study object,the heat preservation effect of which through measuring the temperarure in December and Janunary was analyzed.The results showed that the temperature indoor increase obviously in sunny days,the quickest temperature increase may be 5～9 ℃ each hour.In cloudy day,the lowest temperature in the room is about-1 ℃ in early morning,which is lower than the minimum growth temperature of the common crops.Through the analysis of accumulated temperature in January,activity accumulated temperature of 0 ℃ was 299.7 degree,and 10 ℃ was 199.7 degree,the effective accumulated temperature of 0 ℃ was 299.7 degree and 10 ℃ only reached 49.7 degree.In the greenhouse the hightest ground temperature was 23 ℃ and the lowest temperature may reach 5 ℃.The average ground temperature of 10 cm and the 30 cm was 11 ℃,13 ℃ respectively,the ground temperature of other depths are between them.relative humidity in greenhouse was above 65%,the humidity could maintain above 80% in the sunny day.Through the analysis showed that it is suitable for planting cold resistant crops in this period,in this greenhouse.更多还原
