三连栋日光温室的结构设计与建造

Structure Design and Construction of Three-span Sunlight Greenhouse

针对日光温室土地利用率低、规模小不利于机械化操作,连栋日光温室节能效果差、运行成本高等问题,设计了三连栋日光温室,并制定出建造规范。研制出的三连栋日光温室空间大,环境较稳定,便于机械化操作;土地利用率提高到90%以上;采光和保温性能优,延长了蔬菜生产周期,大大提高了设施的利用率;利用集雨蓄水系统蓄积的雨水灌溉蔬菜,大大缓解了地下水供需的矛盾。

Aiming at the problems of low land-use efficiency and small scale for the sunlight greenhouse , poor save-energy effect and high operational cost for multi-span sunlight greenhouse, the three-span sunlight greenhouse was desighed, and the construction specification was drawn up.Developed three-span sunlight greenhouse had large space, stable environment, good lighting and keeping-temperature performance and is convenient for mechanical operation.By which the land-use efficiency was increased more than 90%, the vegetable produce cycle could enlonged and the utilization of facilities was greatly improved , collected rainwater by rainwater-collecting system relieved groundwater resources supply and need contradiction.
