Agricultural film has a "strange" effect on "increasing production and improving quality"?

[Abstract]:
“Although the development of agricultural film industry is only 40 years, the speed of technological iteration innovation is rapid. Zhang Zhenhe, president of the Chinese Society of Agricultural Plastics Applied Technology, is a treasure for the development of the first four generations of agricultural film. In his view, the core of promoting innovative research and development of agricultural film is always to provide consumers with real value. Zhang Zhenhe introduced that in the initial stage of agricultural film research and development, the function was single, limited to heat preservation and frost prevention. "Dew droplets condensed on the inner surface of the film reflect 20% to 30% of the sunlight, resulting in inadequate temperature in the shed. At the same time, the drops of dew are very cold, which can also cause damage to crops. These factors are the leading causes of crop yield reduction and quality degradation. So far, dripping film came into being, but the hazards of "fogging" came one after another, and double anti-frost film (anti-frost and anti-fog) began to sell well in the market. From 1990s to the 10s and 20s of this century, composite multi-functional agricultural film became popular rapidly. In 2015, according to the requirements of the 13th Five-Year Plan, China's agricultural film industry officially opened the fourth stage, "super-long life" has become an important topic of innovation and application. Zhang Zhenhe said that the core of "super-long life" lies in alleviating the pressure of labor scarcity, promoting cost savings and increasing agricultural added value, etc. The new concept of functional agricultural film was further proposed.

    In recent years, new functional greenhouse film has achieved fruitful results in the cultivation of fruit and vegetable crops such as strawberry, grape, peach, tomato, eggplant, color pepper and so on. Strawberry is big, tastes sweet, colors well and yields increase by about 20%. According to reports, for functional agricultural film, agricultural plastic branch of the agricultural film enterprises are trying to develop new products, seize the market highland.

    At the meeting, Qin Lijie, chairman of Agricultural Plastic Products Branch of China Agricultural Plastics Applied Technology Society, shared data that showed that the development speed of functional agricultural film in China was significantly accelerated. At present, functional film has accounted for about 70% of the total product, functional film accounted for more than 5% of the total product.
