What color glass, plastic film or supplementary light source should be chosen for growing vegetables in greenhouse?
Eggplant is the focus of coloring bar, as well as the impact of diseases and pests. Of course, the price depends.(2) PE longevity film,(3) long life without dropping film;(4) multifunctional membrane;(5) diffuse reflection film(6) light transfer film(8) PVC without dropping film;(9) ethylene vinyl acetate copolymer (EVA);
Hello friends, plastic greenhouse planting eggplant fruit vegetables suitable plastic film is EVA film, PO membrane two kinds, PO membrane price is too high, and use the most common or EVA film.EVA film transmittance, high temperature, fast, good insulation, the price is suitable for every square in a piece of five to two blocks between.Others, such as poly vinyl non dripping film, this is to filter UV, affecting the coloring of vegetables. Grouting film is cheap, the disadvantage is that the temperature is too fast, low transmittance, no drop is too short.
Membrane technical indicators, including light transmittance, no drop performance, anti fog effect, anti-aging, are directly related to the disease, the above indicators are good, the greenhouse disease is light, poor, it will lead to serious diseases. Serious diseases, to fight drugs, production is low, is a direct impact on your performance.I recommend you use the EVA film and other film, PVC. No dip film I am familiar with, kind of melon, Cucurbitaceae, with more than the other film, we rarely use, have been ready to use good films, who do not want to risk a delay is not a season vegetables, to the people to do the experiment.
