Different colors of agricultural film on light absorption, refraction and reflection are different, the impact on crops is also different, its economic benefits vary greatly. Therefore, farmers expect manufacturers to produce a variety of colored agricultural film, agricultural film to meet the needs of different crops and different levels. The following po film manufacturers introduce the characteristics of agricultural film color matching:

Agricultural film color matching Agricultural film developed according to the thermotaxis of vegetable crop roots. It is usually black and white, with a white film band in the cultivation row and a black film band between the rows. In this way, the temperature increase effect of the white film belt is good, and the crop growth stage can promote its early development and fast growth. po film manufacturers believe that although the temperature increase of the black agricultural film belt is poor, it does not affect the early maturity of vegetables because it is far from the crop rhizosphere, and has the function of weeding. Entering the high temperature season, the ground temperature between rows can be low, the roots can be induced to grow between rows, and the crops can be prematurely aged.

First of all, the recycled agricultural film will remove the attached impurities, and then rinse with water, avoid rubbing and beating with a stick. After washing, it should be open to dry in a cool and ventilated place, not exposed to the sun, and windproof to break the film or dry inside and outside. When airing, pull on the rope, spread the greenhouse film on the rope, and fix it with clips to prevent the agricultural film from touching the ground and slipping until dry. After drying, check the film before storage, and repair any damaged areas in time.

Protection method

The thickness of agricultural film products has a great influence on the durability of agricultural film products. Due to different regions, the thickness of domestic greenhouse film and agricultural film is 60μm, 80μm, 100μm and other thickens.

In cold areas, due to the requirements of thermal insulation performance, the thickness of agricultural film is generally 100~120μm, the thickness of agricultural film products, determines the capacity to accommodate drips, so po film manufacturers suggest that in cold areas, the duration of agricultural film drips is longer, and the thickness of agricultural film is thicker.

The above is the introduction of agricultural film thickness, if you are interested, we will share with you one by one later, if you want to know other, welcome to contact us, we will be happy to serve you!

When purchasing agricultural film, we want to choose a functional agricultural film with light transmission, heat preservation, aging resistance, fog elimination and so on. But no matter what kind of agricultural film, in use can not avoid a situation is the phenomenon of water droplets. Now a drip agricultural film has been invented, but the phenomenon of water droplets still occurs. The following po film manufacturers teach you how to do about agricultural film leakage:

The phenomenon of water droplets occurs because we first pay attention to the thermal insulation performance of agricultural film, but the agricultural film is not resistant to the change of temperature difference between high and low, easy to absorb a lot of dust due to infiltration. Generally, when we find that water droplets occur in agricultural film, we can not let it go, otherwise it will affect the crop yield in agricultural film. po film manufacturers suggest that you can grind the soybeans into fine powder, each square meter of the shed film with 7.5 to 10 grams of soybean powder, 150 grams of water, soaked for 2 hours with gauze filtration, remove the droppings and spray with a sprayer against the water droplets on the shed film, which can make the water droplets fall quickly, and can maintain 15 to 20 days without new water droplets.
