According to the cultivation of vegetables and their own conditions, the correct selection of shed film is an important part of the production of shed vegetables. Currently marketed on the market are generally divided into four categories: no drip film, drip film, composite film and purple film. The water droplets gathered on the inner surface of the film after the dripless film (polychlorinated film) are covered can flow along the slope to the front corner of the shed. There is no water drop on the film, and the water permeability is good. The temperature inside the shed is 4-5 degrees higher than that of the drip film, which is favorable in winter. Sheds grow and safely pass winter. There is no water drop under the membrane, and the humidity in the greenhouse is small, which greatly reduces the occurrence of various diseases. High temperatures in the shed, good light, and light disease are important conditions for the high yield and efficiency of sheds. No drop-film aging resistance, generally available for more than 2 years. However, there is no significant liquid film thickness of 10-12um, covering about 125-130kg in a 100m long shed, the price is 20%-30% higher than the drop film. Film width is generally 3-4m, according to the need to bond. The use of this membrane is beneficial to the production of spring fruit and vegetables. After the drip film (polyethylene film) is covered, a large number of water droplets can be accumulated on the inner surface of the film, which seriously affects the light transmittance. The temperature in the shed is low, and the light is weak. Drops of water will fall on the ground at any time. The humidity in the shed is high. Severe disease is not conducive to the growth of vegetables in winter, and the poor yield of fruits and vegetables is poor. Drop film width 8-10m, covered without bonding. The proportion is small, the film thickness is 7-8um, and only 100-80kg is required to cover a 100m long shed, which is cheap. It is suitable for the production of leafy vegetables and cold sheds that are resistant to low temperature and low light such as leeks and celery. Composite film is currently a high-tech product. Synthesized by three layers. The front surface is a dust-proof film that is not treated to absorb dust. In the middle, a high-strength, age-resistant, strong film is sandwiched. On the opposite side, there is a layer of no-drop film. In this way, it focuses on the three major advantages of dust resistance, aging resistance, and no drip. The specific gravity, thickness, and price are similar to those without drip film, making it ideal for use in vegetable greenhouses in winter and spring. However, when using it, you must face it up to receive good results. The violet film absorbs and reflects violet light. Purple light can control the length of vegetables and stems, cover the purple film, make the shed reduce the purple, can promote lush foliage, so that the main stem and leaves of vegetables such as leeks, celery, cabbage, lettuce, rape, spinach, garland chrysanthemum, Parsley, green onions, garlic sprouts, etc., can not only increase production, but also improve quality, with high yield and high efficiency. The cultivation of shed vegetables is only based on their own cultivation of different vegetables and shed structure, and scientific selection of shed film can achieve high yield and high efficiency.
