[0012] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention will be further elaborated below.
[0013] A material selection method for a winter solar greenhouse, characterized in that it comprises the following steps,
[0014] Step 1. Selection of rear roof materials: mainly materials with good heat storage and insulation, and tight sealing, such as straw and firewood. The total thickness of the bottom pavement and outer covering reaches 2 / 3 of the maximum thickness of the local permafrost layer. -4 / 5. First lay a layer of asbestos tiles on the inner side, spread 5cm vermiculite on it, and then spread 5cm thick polyethylene foam board, cover the top with 4-5cm prefabricated cement board, and spread 1:3 cement slurry slag on the outside to plaster the slope, and the slope goes uphill Bottom flat, thickness 5-15cm;
[0015] Step 2. Selection of skeleton materials: selection o...
