摘要
冀东新型高效日光温室为钢管竹木结构,采用厚土墙和半地下模式,墙体最底层厚度4.5 m,棚内畦面一般低于水平地面0.5~0.7 m,脊高4.3~4.5 m,跨度10~11 m,前屋面采光角为23.5°~25.0°,后坡仰角为40°~42°,减少了温室南部遮光,有利于清除棚面积雪,提高冬季室内温度。通过实践证明,冀东新型高效日光温室冬季棚内最低温度可保持在12℃以上,即使连续阴雪天气,棚内最低气温也在8℃左右,能确保深冬季节各种喜温蔬菜正常生长,解决了普通日光温室蔬菜深冬生长缓慢、收获期延迟和产量低的难题,非常适合在地下水位低于5 m、土地资源丰富、有发展设施蔬菜和果树需求的平原地区推广建造。
The new high efficiency solar greenhouse in eastern Hebei was a steel tube and bamboo wood structure,which adopted thick wall and semi underground mode.The thickness of the bottom layer of the wall was 4.5 m,the shed surface in the greenhouse was generally 0.5-0.7 m lower than the horizontal ground,the ridge height was 4.3-4.5 m,the span was 10-11 m,and the daylighting angle of the front roof was 23.5°-25.0°,the back slope elevation angle was 40°-42°.It could reduce the shading in the south of greenhouse,clear the snow in greenhouse surface area and improve the indoor temperature in winter.The practices showed that the minimum temperature in the new high efficiency solar greenhouse in eastern Hebei could be kept above 12℃ in winter,even in continuous overcast and snowy weather,the minimum temperature in the greenhouse was about 8℃,which could ensure the normal growth of all kinds of thermophilic vegetables during late winter and solve the problems of slow growth,delayed harvest period and low yield of vegetables in ordinary solar greenhouse during late winter.It was very suitable for promoting construction in the plain area where the groundwater level was below 5 m with abundant land resources and for need to develop facilities of vegetables and fruit trees.
