Embodiment Construction

[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...

Abstract

The invention provides a winter type solar greenhouse material selecting method and relates to the technical field of vegetable greenhouse building. The winter type solar greenhouse material selecting method is characterized by comprising the steps of selecting a back roof material, selecting a framework material, selecting a cover-shed plastic film and selecting a non-transparent outer covering material. The winter type solar greenhouse material selecting method is reasonable, the selection is convenient, and the effect is good.

Description

Technical field: [0001] The invention relates to the technical field of vegetable greenhouse construction, in particular to a material selection method for a winter solar greenhouse. Background technique: [0002] Greenhouse is also called greenhouse. A facility that can transmit light, keep warm (or warm), and be used to grow plants. In seasons that are not suitable for plant growth, it can provide a growth period and increase yield. It is mostly used for planting or raising seedlings of temperature-loving vegetables, flowers, forest trees and other plants in low temperature seasons. There are many types of greenhouses, which can be divided into many types according to different roof truss materials, lighting materials, shapes and heating conditions, such as glass greenhouses, plastic greenhouses; single-span greenhouses, multi-span greenhouses; single-roof greenhouses, double-roof greenhouses; Heated greenhouse, unheated greenhouse, etc. The greenhouse structure should ...
