Biodegradable mulch film, corn yield per mu exceeds one ton!

In 2023, with the strong support of the Science and Education Office of the Provincial Department of Agriculture and Rural Affairs of the Tongchuan Agricultural Science Research Institute of Shaanxi Province, the “Thousand-acre Biodegradable Film Substitution Technology Demonstration for Plastic Film” work was carried out and a ” Corn 5335+ biodegradable film covering planting technology” measures.

In mid-November, technicians conducted actual harvest and yield testing on the 8.5-acre demonstration field transferred to Jiyangzhai Village by Jinchao Greenland Agricultural Machinery Farmers Professional Cooperative in Yintai District. They harvested 21,800 kilograms of corn. After removing impurities and converting it into standard moisture content, the yield was 17,500 kilograms, an average of 17,500 kilograms. The yield per mu is 2,050 kilograms, and the yield per mu exceeds 1 ton, which is 500-800 kilograms higher than the annual corn yield in the area, setting a new high in Tongchuan City’s corn yield with biodegradable mulch film. This work is one of the specific actions taken by the Tongchuan Agricultural Science Institute to implement the strategy of storing food in the ground and storing food in technology. It plays a positive role in reducing the use of plastic mulch films, protecting the agricultural ecological environment and ensuring the safety of food release production. effect.

Tongchuan City is a typical rain-fed agricultural area. Unfavorable weather such as early dryness and frequent low-temperature freezing damage in spring has become one of the factors restricting grain production. The mulching technology popularized in the 1980s has played a role in increasing grain production and increasing farmers’ income. It takes hundreds of years for plastic mulch to degrade under normal circumstances. The white pollution caused by long-term use of mulch film causes the quality of cultivated land to decline year by year, hindering crop growth and reducing yields. In order to give full play to the positive role of mulching technology in increasing temperature, protecting the environment, and increasing production, in recent years, Tongchuan Agricultural Science Institute has carried out research and demonstration work on a variety of ground covering materials to replace traditional plastic mulch technologies, and will cooperate with Yijun in Yintai District in 2023 The county’s mulched corn core planting area carried out a “thousand acres of biodegradable mulch film replacement plastic mulch technology demonstration” work. A survey of demonstration fields by technical personnel at the city and county levels showed that biodegradable mulch has basically the same effect as traditional plastic mulch in increasing the temperature of soil ponds and maintaining soil moisture, without reducing output. The application and promotion of biodegradable mulch films can “reduce plastic” in farmland, “greener” agriculture, and contribute to the high-quality development of agriculture.
