摘　　要：为研究新型结构面包温室性能,特开展面包温室与宁夏二代节能日光温室环境因子变化趋势研究试验,通过分析比较两种日光温室冬春季节气温、地温、空气湿度、CO2浓度、光照强度等环境因子及作物长势、产量等指标的变化趋势,评价两种类型日光温室的保温性、透光性、丰产性等方面的综合性能。结果表明:1~3月份,面包温室地温较二代温室低0.2~1.4℃,气温较二代温室低1.1~1.6℃;面包温室白天空气湿度较二代温室低1.30%~15.7%,夜间空气湿度较二代温室高0.5%~8.2%;CO2浓度较二代温室提高62.9~295.8μg/L;土地利用率较二代温室提高30.5%,净生产面积产量较二代温室低20544 kg/hm^2;以占地面积核算,产量较二代温室高15832.5 kg/hm^2,增产24.1%,单位面积土地产出效益较二代温室高41164.95元/hm^2。To study the characteristics of new structures of greenhouses,the experiment was carried out to study the change trends of environmental factors of greenhouse with the new structure and Ningxia second-generation energy solar greenhouse The change trends of their environmental factors were compared and analyzed,including the winter and spring temperature ground temperature,air humidity,CO2 concentration,illumination intensity,crop growth,yields and etc.Their overall performances were evaluated in terms of heat preservation,light transmittance and high yield and etc.The results showed that compared with the second-generation greenhouse,from January to March,the ground temperature of the new type of greenhouse was 0.2~1.4℃lower;the temperature was 1.1~1.6℃lower;the air humidity was 1.30%~15.7%lower during the day,and was 0.5%~8.2%higher at night;the concentration of CO2 increased by 62.9~295.8μg/L;the land use capacity increased by 30.5%;the net production area yield was 20544 kg/hm^2 lower;according to the occupied area the yield was 15832.5 kg/hm^2 higher,and increased by 24.1%;the output benefit per unit area of land was 41164.95yuan/hm^2 higher.
