Product introduction of heavy duty greenhouse covers

Poly film greenhouse is the most cost-effective greenhouse and welcomed by the users. The traditional tunnel roof design is simple but strong. The heavy duty greenhouse covers can diffuse the light to protect the crop from burning and aid the photosynthesis, but it needs to change every 3-5 years. In the winter, especially in China. heavy duty greenhouse covers m can be laid with a pump to inject the hot air, not only to prevent the dissipation of the heat, but also to stop the cold air going in. So the inside temperature is guaranteed in cold weather. Poly film greenhouse anti-fog and anti-drip design will decrease the chance of the suffering from the disease of the plants . The huge roof ventilation and side ventilation will reduce the heat and humidity to make a temperate environment.

Smart greenhouse systems include:

1. Temperature control system:

The temperature in a smart greenhouse is mainly controlled by solar radiation and ventilation. Therefore, the function of the intelligent temperature control system is to maintain a certain appropriate indoor temperature and stabilize it at a given value to facilitate the growth of crops.

2. Humidity control system:

Changes in air humidity in smart greenhouses are mainly caused by condensation and evaporation of water vapor. Therefore, humidity control also determines the yield and quality of crops to a certain extent. Currently, two commonly used methods include humidifier humidification and fan dehumidification. The control principle is to adjust the relative humidity in the room by changing the air flow into the room. In addition, dehumidifiers or heaters can also be used to remove indoor humidity. of moisture to achieve the purpose of increasing indoor relative humidity (but the cost is higher).

3. Lighting control system:

Light is one of the conditions for crops to perform photosynthesis. At the same time, light is also one of the important factors that affect crop yields. Therefore, the control of light is one of the key factors for the normal growth of crops. The commonly used method is to use sunshade nets for shading and cooling. Or use lighting fill-in and other methods to control and adjust lighting (such as when using LED lamps as light sources).

4. Irrigation system:

The pressure of the circulating water is increased to a certain value through a water pump and then sent to the pipeline for transportation to each greenhouse (generally the water pressure per cubic meter is 0.15~0.2 kg/cm2, that is, there is a pressure of 0.3 kg per square centimeter), and then through The drip irrigation head sprays water to the roots of the plants; in addition, pipes can be buried in the soil to directly supply water to the roots of the plants, or seepage pipes can be set up to directly absorb water from the soil for crops to absorb and utilize.

5. Fertilization system:

Only by rationally designing the amount of fertilizer according to the plant's fertilizer requirements and supplying nutrients in a timely manner can the plant grow and develop normally and obtain high yield and quality (for example, tomatoes require more nitrogen fertilizer).

heavy duty greenhouse covers factory

heavy duty greenhouse covers made in china

1)Internal shading: Install sunshade nets inside the greenhouse.The use of rack and pinion drive, smooth operation, high control precision, long service life, easy maintenance.

2)External shading: Install shading nets on the top of the greenhouse to protect indoor crops from being burned by strong light in summer and reduce the indoor temperature by 4-6°C.

3)Cooling fan: Exhaust moisture and ventilate to ensure the growth of crops

4)Cooling pad: Using the principle of water evaporation and cooling to achieve the purpose of cooling

5)Drip irrigation system:It has a higher water-saving and yield-increasing effect, and can be combined with fertilization to more than double the fertilizer efficiency.

6)Mobile sprinkler : Sprinkler irrigation is not only a water-saving, yield-increasing, high-efficiency irrigation method, but also a high-energy-consumption irrigation method.

7)Fertilization system:Save fertilizer, improve water use efficiency, reduce pests and diseases, increase crop yield and improve quality.

8)Heating system:Even heat dissipation, good heat preservation effect.

9)Mobile seedbed:Manual drive, simple operation, simple movement, moisture-proof.

10)Growing light:LED growing lights control plant growth by regulating light.
