Preferably, described base angle groove is a little more than warm flooring.
Preferably, described heat-insulation layer is XPS heat-insulation layer.
Preferably, described damp-proof layer is BAC double-sided self-adhesive coiled material damp-proof layer.
Preferably, described heat-collection and heat-accumulation groove support is that clay brick is built by laying bricks or stones or pouring concrete.
Preferably, the grid orifice plate of described grid orifice plate heat-collection and heat-accumulation groove is concrete grid orifice plates.
Preferably, described base angle groove near crop side a little more than warm flooring and outdoor ground.
Compare with existing greenhouse technology, tool of the present invention has the following advantages:
1. the non-growing area (base angle, greenhouse) in greenhouse utilizes combined type heat-collection and heat-accumulation thermoregulating system to store certain solar radiation heat daytime, it is relatively little that the heat that both can absorb by day inside greenhouse makes it the temperature difference, again can be when nighttime temperature reduces, thermal release in heat-storing material is out improved to base angle, greenhouse temperature, solved the shortcoming that greenhouse by solar heat base angle at night and middle portion temperature difference are large;
2. reduce the consumption of conventional energy resource, reduced the discharge capacity of carbonic acid gas, protection of the environment;
3. utilize clean, economic solar energy, saved the investment that greenhouse utilizes conventional energy resource heating, improved economic benefit;
4. utilize the advantage that cobble heat conduction and accumulation of heat are fast (the thermal conductivity factor λ=2.2W/ (mK) of cobblestone for example, thermal diffusivity a=11.3 * 10
-7m
2/ s, specific heat capacity c=780J/ (kgK)) be the water that heat capacity ratio (specific heat) is larger (c=4178J/ (kgK)) accumulation of heat, improved accumulation of heat and exothermal efficiency;
5. simple in structure, easy construction, operating cost is low.
