There is finally a way to solve the white pollution of farmland. The history of relying on manual removal of soil residual film in the city for more than 20 years will also come to an end. Yesterday, the Municipal Agricultural Machinery Research Institute and the Ninghe County Agricultural Machinery Bureau jointly held the on-site meeting of the city's residual film recycling mechanization technology promotion in Guzhuang Village, Ninghe County. From next year, this technology will be promoted in the city's scale, and it will completely fight against white pollution.
In recent years, the cotton planting area of ​​this city has been basically stable at about 1 million mu. Most of the areas have been planted for 3 years in a row. Some areas have been planted for more than 5 years, and the “white pollution†caused by the residual film produced by the film-planting technology. Increasingly serious. According to an authoritative film residue test conducted by the Municipal Agricultural Machinery Test and Appraisal Station last year, the land planted in this city for three or four years has reached 16.93 kg and 22.73 kg per mu, indicating that the residual film pollution of most cotton fields in the city is close to serious. degree. In order to solve the problem of “white pollution†in farmland, the city has implemented the demonstration project of introducing new technologies for agricultural machinery since last year.
A few days ago, the reporter saw at the scene of the cotton field that after the cotton stalk cleaning machine was pulled by a common tractor, the long cotton stalk and the residual film of the white flower were respectively pulled out and collected collectively. According to the introduction of the experts of the Municipal Agricultural Machinery Research Institute, the mechanized operation of residual film recycling after cotton harvesting can complete the three steps of cotton stalk extraction, mulching cleaning and rotary tillage, cotton stalk removal rate and residual film. The recovery rate is 95% and 80% respectively, and it can work 4 to 8 mu per hour, which is more than 10 times higher than the manual operation efficiency. The technology has obvious social, economic, environmental and ecological benefits. It is conservatively estimated that each mu of cotton land can increase farmers' income by nearly 100 yuan, and the agricultural production environment is greatly improved.
