Effective Application Of New Environmental Protection Technology In Xinjiang Cotton Field

At present, Xinjiang cotton has entered the spring ploughing and spring sowing period. In order to effectively solve the problem of residual plastic film pollution in farmland, a new technology is being pushed out in the field of Kashgar, and high-strength high-strength high-strength film is widely used to put on environmental protection "new clothes" for cotton fields.

"Last year we did experiments, and compared with ordinary film, its advantage is that the effect of pressing grass is better, and the effect of soil moisture, water and fertilizer is good." Wen Ming, a cotton grower in xiyitidun township of Maigaiti County in Kashgar Prefecture, used the new technology in his own field this year. He told reporters that the recovery rate of gaobao residual film can reach more than 90%.

According to the experimental demonstration report issued by the Key Laboratory of agricultural film pollution prevention and control of the Ministry of agriculture and rural areas and the Institute of agricultural environment and sustainable development of Chinese Academy of Agricultural Sciences, in 2021, the residual film recovery rate of the new high-strength plastic film after six months of use is more than 90%, which is 30% higher than that of the traditional plastic film; The comprehensive cost is reduced by 50 yuan per mu; Cotton yield per unit area increased by 6.5% - 10.4%, and economic income increased by 14.8% - 22.8%. "Gaobao film is high strength and easy to recover, which not only achieves the purpose of recycling residual film, but also saves resources, which has practical significance for controlling white pollution of farmland." Xinjiang Plastic Association Expert Committee Director Zhang Jing said.

According to Liu Zhifu, deputy county chief of Maigaiti County, last year, the county allocated special funds to further strengthen the remediation of farmland residual film pollution, and carried out special subsidies for the application and promotion of gaobao membrane technology, covering an area of 300000 mu. "This year, the planting area of cotton in Maigaiti county has reached 620000 mu. It is hoped that through the further promotion and application of gaobao membrane technology, the problem of farmland white pollution can be effectively controlled." Liu Zhifu said.

It is reported that a circular industrial chain for the production, use, recovery and reuse of gaobao membrane has been established, with a capacity of 20000 tons / year. "After the residual film is recovered, its mechanical properties are still very good. Therefore, the recycled materials after cleaning and granulation will be used to produce high value-added shrink packaging film, so as to achieve the effect of recycling."
