Preservation method of agricultural film
Different colors of agricultural film absorb, refraction and reflect light differently, and have different effects on crops, and their economic benefits are very different. Therefore, farmers expect manufacturers to produce a variety of colored agricultural films, which can meet the needs of different crops and different levels. The following is an introduction to the characteristics of agricultural film color matching:
The color of the agricultural film is based on the thermotaxis of the roots of vegetable crops. Usually black and white, with white film tape for cultivation rows, and a black film tape between the rows. In this way, the white film belt has a good effect in warming, and the early stage of crop growth can promote early growth and growth. Although the black agricultural film belt has a poor temperature increase, it is far away from the crop rhizosphere and basically does not affect the early maturity of vegetables. Features. In the high temperature season, the ground temperature between the rows can be lowered, and the root system can be induced to grow between the rows, which can lead to premature aging of crops.
First remove the attached impurities from the recycled agricultural film, and then rinse it with clean water. Avoid rubbing it with your hands and beating it with a stick. After washing, it should be spread open to dry in a cool, ventilated place, not exposed to the sun, and protected from wind blowing and scratching the film or drying inside and outside. Pull on the rope when drying, unfold the greenhouse film on the rope, and fix it with a clamp to prevent the agricultural film from contacting the ground and slipping off until it dries. After drying, check the film before storage, and repair any damaged areas in time.
The thickness of the agricultural film product has a great influence on the durability of the drip agent of the agricultural film product. Due to different regions, the thickness of domestic greenhouse film and agricultural film has various thicknesses such as 60μm, 80μm and 100μm.
In cold areas, due to the requirements of thermal insulation, the thickness of agricultural film is generally 100~120μm. The thickness of agricultural film products determines the capacity of the drip agent. Therefore, in cold areas, the agricultural film drip agent is effective The period is longer, and the thickness of the agricultural film is thicker.
The above is an introduction to the thickness of agricultural film. If you are interested, we will share it with you later. If you want to know more, please contact us and we will serve you wholeheartedly!
When purchasing agricultural film, we want to choose functional agricultural film with light transmission, heat preservation, aging resistance, anti-fogging, etc. But no matter what kind of agricultural film, there is a situation that cannot be avoided in use is the phenomenon of water droplets. A dripping agricultural film has also been invented, but the phenomenon of water droplets still occurs from time to time. Let me teach you how to deal with the leakage of agricultural film:
The water drop phenomenon occurs because we first pay attention to the thermal insulation performance of the agricultural film, but the agricultural film is not resistant to changes in high and low temperature, and it is easy to absorb a large amount of dust due to the adsorption. Generally, when we find that there are water drops in the agricultural film, we should not let it go. Otherwise, it will have an impact on the crop yield in the agricultural film. Grind soybeans into fine powder, use 7.5-10 grams of soybean powder per square meter of greenhouse film, 150 grams of water, soak for 2 hours and filter with gauze. After removing the residue, spray it with a sprayer against the water droplets on the greenhouse film. The water droplets fall quickly and can keep no new water droplets for 15-20 days.
