Product Description

Solar greenhouse is a kind of greenhouse widely used in north China. It mainly relies on solar radiation to maintain the indoor temperature, usually sitting north and south, extending east and west. Its structure mainly includes wall, back roof, front roof and other parts.
 

Product Description

Skeleton structure

The common skeleton has bamboo and wood structure, steel skeleton structure and so on. The cost of bamboo and wood structure is low, and the bamboo pole is generally used as an arch, and the wooden pole is used as a column to support. The advantages of this structure are convenient materials, cheap prices, suitable for small-scale planting and limited funds of farmers. However, the durability of bamboo and wood structure is poor, and some components need to be replaced regularly. The steel skeleton structure is more durable and can withstand large wind and snow loads. For example, the hot-dip galvanized steel pipe skeleton, its good rust resistance, long service life, usually can reach about 15-20 years, and its shape is regular, easy to install plastic film and other covering materials.

Wall section
The function of the wall is mainly heat preservation and heat storage. There are earth walls and brick walls. The insulation performance of earth walls is very good, because the soil itself is a good heat storage material. At the time of construction, the thickness of the earth wall is generally about 0.8-1.5 meters, and the thick earth wall can absorb and store a lot of solar heat during the day, and release it slowly at night to maintain the indoor temperature. Brick walls are relatively stronger and have a neat appearance. In order to improve the thermal insulation performance of brick walls, hollow brick walls are sometimes used, and thermal insulation materials are filled in the middle, such as perlite, polystyrene foam board, etc., and the thickness of the brick wall is usually about 0.24-0.37 meters.

Covering material
The main covering material is plastic film, which is the key to obtaining light in daylight greenhouses. Commonly used plastic films are polyethylene (PE) film and polyvinyl chloride (PVC) film. PE film light transmittance is good, the price is relatively low, its light transmittance can reach about 90%, but the insulation performance is slightly worse. The thermal insulation performance of PVC film is better than that of PE film, but the light transmittance is slightly lower, generally about 80-85%. In addition, in order to improve the thermal insulation effect at night, the plastic film will be covered with thermal insulation quilt or straw curtain. Thermal insulation quilt insulation effect is good, and relatively light, easy to operate, the curtain is lower cost, but more bulky.

Product characteristics

1. Efficient use of solar energy: make full use of solar radiant energy, reduce dependence on other energy sources, have a good energy-saving effect, in line with the requirements of sustainable development.

2. Anti-season planting advantages: It can plant vegetables, flowers and other crops in the cold season, providing anti-season agricultural products for the market and increasing farmers' income. For example, fresh tomatoes, cucumbers and other vegetables can be grown in the northern winter.

3. Relatively simple construction: Compared with some large multi-storey greenhouses, the structure of daylight greenhouses is relatively simple, and the construction cost is low, which is suitable for the majority of farmers and small and medium-sized agricultural enterprises.

Product System

Temperature control During the day, the temperature in the greenhouse is raised mainly by sunlight. In order to prevent the temperature from being too high, there is generally a vent at the top of the greenhouse, and when the temperature reaches a certain value (such as 28-30 ° C), the vent can be opened for ventilation and cooling. At night, reduce heat loss by putting down insulation blankets or curtains. In addition, some modern daylight greenhouses are also equipped with auxiliary heating equipment, such as hot fans, water heating equipment, etc., for maintaining the indoor temperature in extreme cold weather.

Light regulation Due to the aging and pollution of the greenhouse covering materials over time, the light transmittance decreases. Therefore, it is necessary to clean the plastic film regularly to ensure good lighting conditions. In the season or weather conditions of insufficient light, artificial light can also be used, such as the installation of plant growth lights (such as LED plant lights), which can adjust the light intensity and spectrum according to the needs of crop growth, and promote the photosynthesis of crops.

Humidity control Humidity in greenhouses is usually higher because water vapor produced by ground evaporation and crop transpiration is not easily dispersed. Humidity can be reduced by ventilation, and when the temperature is high during the day, the ventilation time and ventilation volume are appropriately increased, and the humidity is controlled within the appropriate range (generally relative humidity is 60-80%). In addition, ground mulch can also be used to reduce ground water evaporation, thereby reducing humidity.

Daylight greenhouse, also known as daylight greenhouse, is a single-roof greenhouse. It mainly uses solar radiation for lighting and warming, and is an important type of facility agriculture. It usually sits north and south in order to maximize the absorption of sunlight, and its structural characteristics make the indoor heat accumulation during the day, to a certain extent, resist the cold climate outside, extend the growth cycle of crops, and achieve anti-season planting.
