在北方冬春蔬菜育苗和生产主要靠人工加温的温室。目前绝大部分的温室塞本上属于“北京改良式温室”的形式。温室低矮而且加温系统部设在屋面下靠近北墙根处。靠近加温系统的南边是人行道,人行道南边是栽培床,栽培床在同一水平面上。我们经过多年的使用和观察,觉得这样布局不够理想,弊病不少。1978年我市王禇公社定和三队对其进行了改造。使用至今效果一直很好。
Spring and winter vegetables in northern nursery and production mainly rely on artificial heating of the greenhouse. At present, most of the greenhouse on the capitals belong to the “Beijing modified greenhouses” form. The greenhouse is low and the heating system is located under the roof near the north wall. To the south of the warming system is the sidewalk, to the south of the sidewalk is a cultivation bed, which is on the same level. After years of using and observing, we think this kind of layout is not ideal and there are many drawbacks. In 1978 the city of Wang Tuan commune set and three teams to its transformation. The effect has been good until now.
