CCTV News: At present, it is the critical period of rapeseed field management and maintenance. Chongqing has carried out unified prevention and control through plant protection drones, and scientific and technological forces have pressed the "accelerator" for spring farming production.

In the past few days, more than 320,000 acres of rapeseed in Tongnan District, Chongqing have ushered in its initial flowering period. In this planting base in Chongkan Town, two drones are spraying mixed fertilizer along the set route. Through such precise operations, "one spray and multiple effects" can be achieved, which can not only supplement foliar fertilizer to promote growth, but also prevent and control diseases and pests such as sclerosis and aphids, and also enhance crop stress resistance, laying a solid foundation for stabilizing production and increasing income.

Tongnan District is one of the largest rapeseed cultivation areas in Chongqing, with a coverage rate of more than 99%. Agricultural technicians formed multiple service teams to go to the fields to provide detailed guidance on prominent issues such as high incidence of sclerosis and weak seedlings to strengthen. In Shangyu Town, Wuxi County, the rapeseed fields are green, and the drone sprays fertilizer evenly, covering the rapeseed with a layer of "protective clothing". This year, in order to improve the efficiency of spring management, the local area has hired a professional flight defense service team and provided certain subsidies to help stabilize the production and increase income of rapeseed.

The national winter wheat area remains stable and ushers in a critical period of returning to greenery

As the temperature steadily rebounds, winter wheat across the country has gradually ushered in a critical period of returning to greenery. At present, the field management of winter wheat, the main summer grain variety in my country, has been carried out on a large scale in spring.

This year, the national winter wheat area remained stable. At present, winter wheat in most areas has entered the period of greening and rising.

More than 60 million mu of winter wheat in Shandong are gradually returning to green. In Mamiao Town, Jinxiang, this year, a smart agricultural system was built, and satellite monitoring and field measurement methods were adopted to divide the wheat fields into grids, and pest warning maps and growth analysis maps were generated every week for precise management.

More than 33 million mu of winter wheat in Hebei grew better than usual. More than 100 provincial experts from the local area provided "one-on-one" guidance, and 45,000 village-level agricultural technicians participated to ensure that each wheat field had a dedicated service.

More than 12 million mu of wheat in the Guanzhong Plain in Shaanxi Province have gradually returned to green. At this intelligent irrigation demonstration site of 10,000 acres of wheat fields in Chang'an, the reporter saw that various water-saving irrigation modes such as high-rod sprinkler irrigation and micro-spraying irrigation make spring irrigation high-quality and efficient.

The winter wheat in the southwest region has begun to thrust.
