At present, cotton in Xinjiang has entered the spring plowing and sowing period. In order to effectively solve the pollution of farmland residual film, a new technology is being rolled out in the fields of Kashgar. High-strength high-strength film is used in large areas to clothe cotton fields. Environmentally friendly “new clothes”.
“We did an experiment last year. Compared with ordinary membranes, its advantage is that it has a better grass-pressing effect, retains moisture and fertilizers, and the effect is good.” Wen Wen, a cotton grower in Xiyitidun Township, Maigaiti County, Kashgar Prefecture Ming used this new technology in his field this year. He told reporters that the recovery rate of Gaobao membrane residual film can reach more than 90%.
According to a test demonstration report issued by the Key Laboratory of Agricultural Film Pollution Prevention and Control of the Ministry of Agriculture and Rural Affairs and the Institute of Agricultural Environment and Sustainable Development of the Chinese Academy of Agricultural Sciences, the 2021 new high-strength mulch film has a residual film recovery rate of up to 6 months after use. More than 90%, 30% higher than traditional mulching film recycling rate; comprehensive cost reduced by 50 yuan per mu; cotton yield increased by 6.5%-10.4%, economic income increased by 14.8%-22.8%. “Gaobao film is high-strength and easy to recycle. It not only achieves the purpose of recycling residual film, but also saves resources. It has practical significance for controlling white pollution in farmland.” said Zhang Jing, director of the expert committee of Xinjiang Plastics Association.
According to Liu Zhifu, deputy magistrate of Maigaiti County, last year, the county allocated special funds to further increase the efforts to remediate residual film pollution in farmland, and provided special subsidies for the application and promotion of Gaobao membrane technology, covering an area of 30 Thousands of acres. “This year, the cotton planting area in Maigaiti County has reached 620,000 acres. We hope that through the further promotion and use of Gaobao membrane technology, we can effectively control the problem of white pollution in farmland.” Liu Zhifu said.
It is reported that a recycling industry chain of production, use, recycling and reuse of Gaobao membrane has been established, with a production capacity of 20,000 tons/year. “After the residual film is recycled, its mechanical properties are still very good. Therefore, the recycled material after cleaning and granulation will be used to produce high value-added shrink packaging film to achieve the effect of recycling.” Maigaiti Starlink Technology said Deng Zhu, deputy general manager of Agricultural Film Co., Ltd.
