The greenhouse is to cover a certain area to make it controllable, so that heating equipment can be set up in the greenhouse to simulate the environment suitable for the growth of vegetables. However, the growth of vegetables needs sunlight, so there are several ways to heat up the greenhouse in the greenhouse, so let's take a look at it together.
1. In order to better play the thermal insulation effect, the semi-underground furrow surface should be considered in the construction of the greenhouse, that is, the indoor furrow surface is built 30-40 cm lower than the outdoor ground, so that the heat storage is more reasonable.
2. Under normal circumstances, the back slope of the greenhouse construction is facing north, sitting north and facing south, and the elevation angle of the back slope is about 45 degrees, which can enhance the light and heat storage capacity of the back slope.
3. In order to prevent cold weather in winter, especially in the northern region, the thickness of the wall and back slope of the greenhouse needs to be thickened during the construction of greenhouses.
4. Use the storage pool to increase the temperature, dig a storage pool at intervals in the greenhouse, spread plastic film at the bottom of the pool, then fill it with clean water, and then cover the upper part of the pool with a transparent film (to prevent the water in the pool from evaporating and increase the air humidity in the shed).

5. Clean and scrub the shed film frequently, and remove the dust, dirt and snow on the shed film in time to increase the light and increase the temperature of the shed.
