| 针对日光温室后墙蓄热效率较低的问题，研究一种后墙主动蓄热的青海型日光温室。对青海型日光温室与普通日光温室室内温度、光照、地温及不同深度墙体温度进行测定，比较2种类型温室室内温度、湿度、作物生长指标及产量的差异。结果表明：青海型日光温室较普通日光温室，晴天夜间温度平均高2.1 ℃，阴天平均高 0.9 ℃；湿度方面，青海型日光温室晴天白天平均低4.7%，夜间平均低2.6%，阴天白天平均低2.7%，夜间平均低2.2%；地温晴天平均高1.69 ℃，阴天平均高0.59 ℃；青海型日光温室墙体的蓄热层深度为320~520 mm；青海型日光温室中番茄株高、茎粗等生长指标略优于普通日光温室，番茄采收期产量提高17.8%。 |

| Abstract: |
| In order to solve the problem of low efficiency of solar greenhouses back wall,a new heating storage type solar greenhouse was built in alpine areas.The experimental greenhouse and an ordinary solar greenhouse were measured in The indoor temperature,soil temperature and different parts temperature of the back wall.The result showed that:Compared with ordinary greenhouse,the experimental greenhouse air temperature was 2.1 ℃ higher on average at night in clear day and 0.9 ℃ higher in overcast day;From the aspect of humidity,it was reduced by 4.7% on average in day and 2.6% at night in clear day.While in overcast day,it was reduced by 2.7% on average in day and 2.2% at night;Soil temperature of the experimental greenhouse was 1.69 ℃ higher on average in clear day and 0.59 ℃ higher in overcast;Heat storage layer was 320-520 mm depth of the wall.During tomato growth period,the advantages in tomatoes height and stem diameter were obvious.The yield of tomato in the heating storage type solar greenhouse was 17.8% higher than the ordinary greenhouses. |
