po film is a common special tool for greenhouse growers. How to adjust the temperature in the greenhouse film during the whole process of application?

First effective rational layout. When the greenhouse is constructed, it is necessary to have a standard that can fully accept the sun and prevent shading. When selecting a po film, it is recommended to use a drip free film. Greenhouse film must use new film, the greater the total area of the greenhouse, the slower the temperature reduction, the higher the actual effect of heat insulation.

Second is double cover. When the frost comes and the daily low temperature is 0 ~ 4℃, the small arch shed is placed in the greenhouse film, and the sunshade net or no waterproof cloth can be stamped. When the low temperature outside the greenhouse film drops below 0 ° C, the grass sheet is stamped at the skirt plate of the outer field of the greenhouse, the double-layer plastic film is covered on the small arch shed in the greenhouse, and a layer of sunshade net or no waterproof cloth is sandwicked in the middle of the double-layer plastic film, and the edge of the small arch shed near the two sides of the greenhouse is covered with a layer of grass sheet. If the temperature in the po film greenhouse is still too low, a sunshade net can be covered on the top film of the greenhouse, and even two films can be covered at 10 to 20 cm from the top film in the greenhouse.

The above is the method of temperature regulation in the po film. As a user, we should always pay attention to the control of temperature in order to play the role of the po film.
