Focus on the research, design, development and production of new plastics materials
Agricultural film has a "strange" effect on "increasing production and improving quality"? “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.
How to select an agricultural film which can promote the "yield increase and quality improvement" of local crops? n the future, where will agricultural film research and innovation go? On November 12, 2018, at the "2018 Annual Meeting of Agricultural Plastic Products Branch of China Society of Agricultural Plastics Applied Technology" held in Quzhou, Zhejiang Province, more than 300 leaders and authoritative experts of the industry and nearly 150 production enterprises in the agricultural film industry chain gathered to share and discuss these topics.
Agricultural film innovation has great potential: increase production by 20%, market in the morning, but also reduce disease! Agricultural film, as the fourth largest agricultural input in China, often makes growers both anxious and happy. It is gratifying to note that, according to the demonstration data of agricultural film industry in all parts of the country and key crops in 2017, when fertilizers and pesticides are applied in the same way and management techniques, agricultural film can increase crop yield by about 20%, promote early market and reduce diseases. Especially to improve the quality of agricultural products, such as: taste, color, trace elements and vitamin content and other significant effects.
