Description

The spectroscopic ecological energy concentration film for agricultural greenhouses (abbreviated as the spectroscopic film) is a patented product developed by Shandong Kuanli New Material Co., Ltd. for multiple years, and it is also a high-tech product that can promote photosynthesis inside the greenhouse through the adjustment of the plant's growth, which is realized by spectrum and light quality. The spectroscopic film is awarded by the Ministry of Science and Technology with the title of "Advanced Achievement of Ecological Environment Protection", which is regarded as high-tech technology of agricultural films. 

Product Features

● It greatly reduces the application quantity of pesticides and fertilizers and effectively reduces the investment of pesticides. 
● The orange-red light generated by it can accelerate the growth speed of plants, make stems and roots be strong and bring fruit maturation forward for 7-15 days. 
● It can improve the fruit setting rate and the average yield per mu by 15-30%. 
● It can make fruit and vegetables have eye-pleasing colors and well-balanced shapes. At the same time, the sweetness can also be improved to realize a good flavor and high sweetness. 
● It performs well in the aspect of heat preservation, with the features of temperature control and temperature regulation, with the internal temperature 2-3 ℃ higher than that of other films in the winter. 
● Its transmittance rate reaches as high as 89-94%, allowing diffuse scattering light entering the greenhouse to avoid burns of plants. 
● The long service life of 2-5 years greatly reduces the labor cost of building the greenhouse. 
● The natural fragrance and orange-red color are anti-counterfeit labels of the product, with the effect of pest-proof and bird-proof, which can greatly reduce the pest damage and bird damage to be borne by fruit and vegetables.
