一、建造简易日光温室时,其走向为东西向,偏西南方向15度,单面式,四周打土墙,其迎光“屋面坡度”,要求在冬至节中午与太阳交角大于或等于50度,屋面坡度各地具体在20～27度左右。具体公式是:23.5+(当地地理纬度-40)×0.5+1。这样增温效果最佳。屋面拱型,半个鸡蛋式。二、设风障或防风墙。在温室北部或西北部离温室1～2米处设防风障,可以起到挡风、挡雪、分散气流的作用。也可以在墙外面设挡风墙,挡风墙离温室墙50厘米,中间填上软草,起防寒保温作用。
First, the construction of simple solar greenhouse, its direction for the east-west, 15 degrees southwest direction, single-sided, playing around the wall, the welcome light “roof slope” requires the midday solstice at noon with the sun greater than or equal to 50 degrees , Roof slope around specifically in the 20 ~ 27 degrees. The specific formula is: 23.5 + (local geographical latitude -40) × 0.5 +1. This warming the best. Roof arch, half an egg-style. Second, set wind barriers or wind walls. In the north or northwest of the greenhouse from the greenhouse 1 to 2 meters at the wind barriers, can play a wind, snow, scattered airflow effect. You can also set a wind wall outside the wall, wind wall 50 cm away from the greenhouse wall, filled with soft grass in the middle, played the role of cold insulation.
