What is film greenhouse?

What film is widely used in greenhouses?

Greenhouse film is generally divided into four categories: po film (non-drip film), pe film (drip film), woven film greenhouse .

plastic film greenhouse advantages and disadvantages

pe greenhouse film

Advantage:

(1) The width is 1-10m, and there is no need to glue when covering, which is more convenient to use.

(2) It only needs 70-80kg to cover a 100m long shed, with few consumables and low price.


Disadvantage:

(1) After covering, a large number of water droplets will gather on the inner surface of the shed film, which is easy to cause excessive humidity and increase diseases.

(2) The presence of water droplets in the film will also seriously affect the light transmittance, resulting in low temperature in the shed and weak light, thereby hindering the growth of vegetables and reducing yield and efficiency.

Suggestion: It is used for the production of leafy vegetables that are resistant to low temperature and weak light, such as leeks and celery, and in cold sheds.

po greenhouse film

Advantage:

1. High transparency and low scattering rate, so the temperature will rise rapidly in the morning.
2. The ability to continuously clean up fog and water droplets, and the fog and droplet elimination period can be synchronized with the service life of the po film.
3. The po film makes most of the infrared rays radiated inside and outside the shed be reflected back. Guarantee the growth temperature of crops at night and shorten the maturity period. It can prevent freezing damage to crops caused by sudden temperature drop at night.
4. Long service life: Using high-tech anti-light stabilizer, the service life of the agricultural film is greatly prolonged, and the normal use can reach more than 3 years.

Disadvantage:

The cost of po greenhouse film is more expensive than that of PE greenhuse film.

White and transparent 120g/㎡(0.15mm)160g/㎡(0.22mm), width 2m~20m, length 50m. Transmittance 80%
Special lengths available in blue or whole meters.

Features:

More than 75% light transmission, high anti-aging performance, high tensile strength, strong wind and rain and hail resistance, good toughness, durable, anti-aging warranty period of 3 years.

Applications:

Chicken, duck and pig sheds and roller shutters (thermal insulation, windproof, waterproof, high tensile strength)

Flower shed (thermal insulation, windproof, waterproof, high tensile strength)

Vegetable, fruit and vegetable greenhouse (thermal insulation, windproof, waterproof, high tensile strength)

Aquaculture insulation shed (thermal insulation, high tensile strength)

What percentage of light should a greenhouse have?

Generally, the requirement for light transmittance is above 75%, but it is not that the higher the light transmittance, the better. The light transmittance of the shed film is high, and the sunlight entering the greenhouse is more energy, which is conducive to the growth of light-loving crops, but the direct sunlight will also damage the crops. Adding an appropriate amount of heat preservation agent to the greenhouse film can reduce the light transmittance, and it is also conducive to the nighttime insulation of the greenhouse. Moreover, the greenhouse film can diffuse the sunlight entering the greenhouse, so that the greenhouse can obtain light energy evenly in all directions.

What is the thickness of film used in greenhouse?

Although reducing the thickness of the film is beneficial to reduce the cost of the greenhouse, the thickness of the film is directly related to the performance and service life of the film, and only the film with a certain thickness can be used normally.
