Recently, the national key research and development plan project 'low-cost manufacturing technology and industrialization of agricultural cover materials with adjustable function and life expectancy' was held in Changchun. The project has made a number of important progress, and the development and application of agricultural film in China is 1. It is multi-functional, long-life, controllable, low-cost, degradable, and special-purpose.
China's agricultural film production and use are the highest in the world, playing an increasingly important role in the development of facility agriculture, improving resource utilization, and achieving high-quality and efficient production of crops. There are fewer special-purpose greenhouse films, high production costs of biodegradable film, product function and crop demand are not matched, and difficult to control and other prominent problems, which restrict the related applications. Around these issues, led by Shandong Agricultural University, Changchun Application of Chinese Academy of Sciences Research institutes of the Institute of Chemistry, Zhejiang University, Beijing Huadun Snowflake Plastics Group Co., Ltd. and Huazhong University of Science and Technology have jointly conducted research on the low-cost manufacturing technology and industrialization of agricultural cover materials with adjustable function and longevity. Collaborative innovation in production, education and research has achieved good results.
The researchers of Changchun Yinghua Institute have made breakthroughs in key technologies such as long life, high grafting, double light effect, enhanced coating synergy and low cost manufacturing through custom-made shed film special materials. The new product system regulates the dripping of the film. , anti-fog, dust-proof, dimming and other functions, technical transformation of 6000 tons / year energy-saving high-efficiency shed film production line, some of the key indicators of the product exceeds similar foreign products. Researchers have explored the light quality requirements of sweet pepper, tomato, eggplant and other crops. The special shed film of the solanaceous vegetables developed has improved the crop quality and increased the yield by 10-30%. The results have been extended to 5 domestic enterprises, and the new products are used in 10 provinces and cities, and the demonstration application is more than 80,000 mu.
