A: In winter, the temperature in the night is very low. During the daytime, when the sun shines and the temperature rises, the trunk is dark brown and easy to absorb heat. The trunk temperature also rises quickly. It is so cold and hot that it is easy to freeze the trunk. crack. Because the lime is white, it can reflect a part of the sunlight and make the trunk not much different in temperature during the day and night. It is not easy to crack, delay the germination and flowering of fruit trees and prevent early spring frost.

Agricultural PO film is a high-tech coating product, and is an upgraded product of EVA film,Po film is widely used in Light Deprivation Greenhouse.PO film is a new type of agricultural film produced by external spraying drying,process with advanced olefin raw materials and other additives in Japan. It has outstanding comparative advantages with traditional PE film and EVA film on the market.It has outstanding comparative advantages with traditional PE film and EVA film on the market and is widely used in Strawberry Greenhouse.
Advantage:
1.Excellent transparency: low fog, high transparency high light transmittance, low scattering rate, so it will heat up quickly in the morning.
2.Super continuous fogging and dripping ability: using fogging and dripping agent coating and drying treatment, can inhibit the generation of fog, fogging and dripping period can be synchronized with the service life of agricultural film.
3.Strengthen heat preservation performance: adopt high-tech special organic heat preservation agent, effectively control heat loss, effectively prevent the sudden drop of night temperature caused by freezing damage to crops.
4.Long service life: the use of high-tech antioxidant and light stabilizer, greatly extend the service life of agricultural film.
5.Super tensile strength: raw materials have super tensile strength and tear strength.
