How long can the effect of greenhouse agricultural film last

Grout film is the main force of China's agricultural science and technology, grout film has good anti-fog, strong dripping, premature vegetable production and early maturation, good sunlight penetration and other characteristics. It provides good convenience for the planting and development of crops in China. The use of grout film products has three advantages: continuous anti-fog dripping, good light transmission, and good longevity function. It can be of great help to save agricultural production capital and ensure crop production efficiency and growth effect.
Continuous anti-fog dripping: agricultural plastic film needs continuous anti-fog drip performance, due to the internal and external temperature and humidity of the plastic film has a gap, so the plastic film has fog and water vapor is obvious, when the water vapor in the shed film to form small water droplets is harmful to crops. Because water droplets reflect sunlight, this will have an adverse effect on the photosynthesis of green leaves of crops, because the refraction of sunlight by water droplets greatly reduces the absorption rate of green leaves. There is a layer of chemicals on the surface of the plastic film, and these water droplets will be mixed with some chemicals that harm the surface of the plant. When water droplets drip on the surface of crops, it is easy to cause crop wilting. Therefore, the continuous anti-fog drip performance makes the growth of crops more quality. The dripping and anti-fogging film period of the grout film can reach between 6-8 months.
Good light transmittance: the light transmittance of the grout film is good, which can make the crops get full light. This is good for the growth of crops. The characteristics of strong direct light and fast increase in ground temperature improve the photosynthesis of crops and promote premature production and early maturity of crops.
Long service life: we know that plastic film is easy to age, especially in summer, the sun is hot, but also relatively strong, strong sunlight on the plastic, easy to cause aging, aging plastic film manifested as: the surface is white, the light transmittance is greatly reduced, hard and brittle, a rub to break. Even if such plastic film continues to be used, it will not help crops, but hinder crop growth. This is why ordinary agricultural film is changed once a year. Therefore, we need longer-life plastic film products. The grout film can achieve this effect. Due to the abundant liquid in the grout film, these liquids have a good maintenance effect on agricultural plastic film.
