- 摘要:
- 以宁夏日光温室和塑料大棚环境为研究对象,对比分析了2种设施条件下室内空气温湿度和15 cm土壤温度,以促进当地设施农业发展。结果表明:从室内气温上看,日光温室气温高于塑料大棚;晴天二者日均气温相差2.3℃,但差异不显著;阴天二者相差2.2℃,差异显著。从季节变化来看,也是日光温室气温高于塑料大棚的温度;从室内土壤温度上看,日光温室土壤温度高于塑料大棚土壤温度;晴天二者日均土温相差1.2℃,差异显著;阴天二者相差2.6℃,差异显著。从室内湿度上看,晴天日光温室平均湿度大于塑料大棚空气湿度,二者平均值分别为73.4%、70.2%;阴天也是日光温室空气湿度大于塑料棚空气湿度,均值分别为81.4%、76.0%,但差异均不显著。从季节变化来看,整个试验期日光温室空气湿度平均为68.2%,塑料大棚为72.1%,二者结论相反,这与温室管理无法统一有关。
- Abstract:
- Taking solar greenhouse and plastic greenhouse in Ningxia as research object,air temperature and humidity,soil temperature at depth of 15 cm in two greenhouses were comparatively analyzed,in order to promote the development of facility agriculture.The results showed that,in terms of indoor air temperature,the temperature in a solar greenhouse was higher than the plastic greenhouse.On sunny days,the average temperature in a solar greenhouse during a day was 2.3℃ higher than in the plastic greenhouse,but the difference was not so obvious on sunny days.On cloudy days,the average temperature in a solar greenhouse during a day was 2.2℃ higher than in the plastic greenhouse,the difference was so obvious on cloudy days.The condition was the same according to the changes of the seasons.In terms of indoor soil temperature,the soil temperature in a solar greenhouse was higher than the plastic greenhouse.On sunny days,the average soil temperature in a solar greenhouse during a day was 1.2℃ higher than in the plastic greenhouse,the difference was so obvious on sunny days.On cloudy days,the average soil temperature in a solar greenhouse during a day was 2.6℃ higher than in the plastic greenhouse,the difference was so obvious too.In terms of indoor humidity,on sunny days,the average humidity in a solar greenhouse was higher than in the plastic greenhouse,the average values were 73.4% and 70.2% respectively.On cloudy days,the average humidity in a solar greenhouse was higher than in the plastic greenhouse too,the average values are 81.4% and 76.0% respectively.but the difference was not so obvious on cloudy days.According to the changes of the seasons,the average humidity in a solar greenhouse and in the plastic greenhouse were 68.2% and 72.1% in the whole experimental period,evidence showed the reverse that dues to different management.This research was of great significance to explore the different types of facilities agriculture development.
