The alternative application of biodegradable mulching film is an important measure to solve the pollution of residual film in farmland soil and promote the sustainable development of agriculture. The materials team of the Institute of Bioengineering, Guangdong Academy of Sciences, in accordance with the needs of the country’s green development of agriculture, and relying on the”Functional Biomaterials Innovation Capability Building” project, has carried out a lot of innovative research work around the preparation and processing of biodegradable mulch composite materials. , And demonstrate application in winter potato planting area in Yuanzhou Town, Boluo County, Huizhou City. On March 18, the project team invited leaders of relevant departments in Guangdong Province and Huizhou City, well-known experts from scientific research institutes, media reporters and local farmers to evaluate the application effects of the fully biodegradable plastic film mulching cultivation technology.
Senior Engineer Xie Dong, a key member of the project team and deputy director of the Institute’s Bioengineering Research Office, introduced the basic situation of the project team and the content of this on-site evaluation. The materials team of the Institute has been committed to the environmental protection of agricultural arable land and the development and application of agricultural environmental protection materials for many years. According to Guangdong’s climate characteristics and crop physiological characteristics, it has developed a variety of fully biodegradable mulching films and supporting cultivation techniques, and has been in the province. Demonstration, application and promotion will be carried out on various crops. This on-site evaluation mainly investigates the impact of biodegradable mulching film on potato yield and the occurrence of green potatoes, in order to evaluate the degradation effect of biodegradable mulching film and the suitability of mechanized harvesting.
Zhang Yucan, a second-level investigator from the Planting Division of the Department of Agriculture and Rural Affairs of Guangdong Province, highly praised the results of the project team and introduced the current status of the research and development and application of the fully biodegradable mulch film in the province. At present, Guangdong Province has successfully applied fully biodegradable mulch film on 13 crops, and achieved good demonstration effects, and the overall level is in the forefront of the country. Experts from South China University of Technology, Guangdong Agricultural Environmental Protection and Rural Energy Station, and Agricultural Resources and Environment Research Institute of Guangdong Academy of Agricultural Sciences affirmed the demonstration effect after listening to the report of the project team and on-site evaluation. After the application of the fully biodegradable mulch film, the potato output increased by 3.06%compared with the ordinary mulch film, and the yield increased by 31.31%compared with the non-cover film. The fully biodegradable mulch film has obvious cracks during the potato harvesting period, has a good degradation effect, can meet the requirements of mechanized harvesting, is conducive to large-scale production, and can produce good economic benefits. Moreover, it degrades in the soil, is environmentally friendly, meets the needs of modern agricultural development, has good ecological benefits, and can be popularized and applied in a large area.
Huizhou local agricultural technicians, media reporters and farmers friends praised the application effect and significance of the fully biodegradable plastic film mulching cultivation technology. The results of the on-site evaluation were reported by the”Money Tree” column of Guangdong Radio and Television Station and the Southern Rural News.
