目前辽南地区使用的温室,多是由前屋面、后屋面、后墙组成。后屋面长1.2—1.6米,后墙高1.7米左右,宽0.5米左右。在生产中存在着的主要问题是:后屋面遮阴,影响光照;后屋面及后墙太薄,冬季保温性能不好,很难保持黄瓜生长所需的下限温度。近几年有的地方采取后墙培土,后屋面加厚等措施,多是一年一整理,用工量太大。为了克服上述问题,我们设计了一种新型温室,前屋面采光角度科学,无后屋面,后墙高2.5米,后墙及东西山墙加厚到0.9米,(当地冻土层为0.7—0.9米),中间夹0.4米厚稻壳保温。后墙及东西山墙内侧抹白灰,增加反射光。(见图1)。
Currently used in southern Liaoning greenhouse, mostly by the front roof, after the roof, composed of the back wall. After the roof 1.2-1.6 meters long, about 1.7 meters high after the wall, about 0.5 meters wide. The main problems in the production are: shading the rear roof, affecting the light; after the roof and the back wall is too thin, poor insulation in winter, it is difficult to maintain the minimum temperature required for the growth of cucumber. Some places in recent years to take the rear wall soil, thickening and other measures after the roof, mostly finishing a year, the amount of labor is too large. In order to overcome the above problems, we have designed a new type of greenhouse with a scientific front-facing lighting concept. There is no rear roof, 2.5 meters behind the back wall, thickened back walls and east-west gables to 0.9 meters (0.7-0.9 meters ), The middle folder 0.4 m thick rice hull insulation. The inside of the back wall and things gable wipe gray, increase the reflected light. (see picture 1).
