一、家庭温室的产生绥棱林业局北股流林场的最低气温在零下42℃左右。当地群众每到冬季都用塑料薄膜贴封窗门,有的甚至用双层塑料里外贴封。能否把前窗的防寒保温薄膜扩大空间,顺房檐斜坡延伸到地面,形成一定的塑料薄膜空间,既保温住室,又能利用其空间与地面栽培菇菜,解决冬春长达七个月的食菜问题呢?笔者经两冬的家庭试验,并结合各地的实践调查很有启发。第一、关于住室日光透度问题。经试验证明,设家庭温室的住室光照与窗内外贴封薄膜防寒的住室光照并无显著差别,其透视
First, the generation of family greenhouses Sulei Forestry Bureau North Stream forest minimum temperature of minus 42 ℃. Every winter, the local people use plastic film to seal the windows, and some even use double-layer plastic to seal the windows. Can the front window of the cold insulation film to expand the space, along the eaves slope extends to the ground, forming a certain plastic film space, both insulation room, but also the use of space and ground mushroom cultivation, solve winter and spring up to seven months Food problem? The author after two winter’s family test, combined with the practice of the survey is very inspired. First, on the issue of sun room penetration. Proved by experiments, it is no significant difference to set the house light of the family greenhouse and the house light of the cold proofing film inside and outside the window, the perspective
