Jining City Create Inada Field Returning Governance Mode

Jining City is located in the hinterland of the southwestern Luban. It is an important commodity grain production base in the country. Among them, the area of ​​rice fields is 630,900 mu. At the same time, our city is the "2+26" channel city in Beijing, Tianjin, and Hebei. It is one of the cities along Huang 9 in Shandong Province. Special geographical location has put forward higher requirements for the green development of agricultural.

The reporter learned from the Municipal Agricultural and Rural Bureau yesterday that around the paddy field retirement management, the bureau established the leading group and expert technical service guidance group of agricultural ecological environmental protection work. The feasibility study report of nitrogen and phosphorus surface source pollution control project ", which clarifies the principles of" source reduction, circulation utilization, process control, end governance ", and formulated the" Jining City Daitian Returning Water Management Work Plan ". It is planned to use 3 The annual time has completed the comprehensive rectification and ecological transformation of the lake area. Among them, 93,500 acres of 2021 (first phase), 380,400 mu in 2022 (second phase), and the remaining 157,000 mu was completed in 2023 (No. 3).

According to reports, the city has strengthened soil measurement formula fertilizer, promoted new fertilizer such as controlling fertilizer, biological fungi fertilizer, reducing the amount of fertilizer fertilizer, and increasing the utilization rate of chemical fertilizers. Strengthen the monitoring and early warning of pests and insect pests, timely release the forecast of diseases and insect warning, promote the use of high -efficiency, low toxic, low residual pesticides, and promote the application of green prevention and control technology such as insecticidal lights, sticky insect plates, and sexual seductive agents to reduce the amount of pesticides. At the same time, actively promoting straw tied to the field not only effectively reduces the labor intensity of the growers, prevents the stacks of straws, and dump the ditch to pollute the water body. It can also solve the hidden dangers of incineration and reduce air pollution.

In accordance with the concept of "accommodation, control, purification, and cycle use", relying on high -standard farmland construction projects, the city's city to expand the carrier capacity of the main canal water body, form a system of mutual connectivity, reasonably set up the system of control, control the flow of water, and two in the main canal. Inside the side, cultivate plants with strong absorption and purification function, filter purification and absorbing and purifying the water body, improve the quality of farmland degraded water, and retreat the farmland stored in the main canal, and achieve recycling. Since last year, there are 18 newly built, rebuilt and irrigation stations, 14 repairs, 962 new bridges and culverts, 450 repairs, 137.7 kilometers of hardening ditch, and 507.1 kilometers of dredging canal.

In order to achieve the double harvest of ecological benefits and economic benefits, the city's construction in the area along the river and the lakes along the river improves the ecological breeding base of rice dumpling shrimp, develop rice dumpling shrimp, rice frogs, and improve the symbiotic ecological species of rice dumplings and rice frogs. In the maintenance model, crayfish and black spots can ingest the weeds and pests in the rice fields. The excrement of crayfish and black spots can also play a role in fat. Since 2021, the city's newly converted and transformed rice dumplings (frog) bases of more than 22,000 acres. In addition, the city also actively builds artificial wetlands and ecological ditches in regions with conditions. In combination with the actual situation, the towns and streets will be transformed and promoted to the original drainage ditch system. The absorption effect improves the ability of water body purification.
