CCTV News: At present, various rice seedling cultivation sites in Jinhua City, Zhejiang are speeding up seedling cultivation. This year, many bases have introduced new irrigation systems and technologies to improve the quality of dry seedling cultivation.

In Taoxi Town, Wuyi County, Jinhua City, grower Zhou Guoping is busy in the seedling plant. This fully automatic rice seedling cultivation assembly line can complete the production of 1,200 to 1,500 seedling trays per hour. After the prepared seedling tray is germinated and sprouted, it is transported to the fields for seedling cultivation. In order to improve the quality of seedlings and save labor costs, this year, Zhou Guoping introduced the automation technology of rice dry seedling sprinkler irrigation from the Jinhua Agricultural Department.

Zhou Guoping told reporters that in the past, they were all raising seedlings in water, "relying on the weather to make a living". When the weather is not good, they often need to lift the membrane, which is time-consuming and laborious. If the management and maintenance are not in place in time, the quality of the seedlings will also be uneven. Nowadays, seedlings are placed in paved fields and then taken root and sprouted through automated control systems. The survival rate of seedlings can be increased by 10%, and the root system is more developed.

This year, Jinhua City expects to plant early rice in more than 310,000 mu, of which the early rice machine planting area is more than 140,000 mu. Machine planting seedlings are provided by 46 seedling centers and 81 seedling sites. It is expected that early rice seedlings can be completed in mid-April.

Jinan, Shandong: Science and Technology + Service Helps Fine Spring Pipe of Wheat Fields

In Jinan, Shandong, winter wheat is in a critical period of field management and yield formation. Local agricultural technicians comprehensively use plant protection drones, integrated water and fertilizer smart drip irrigation and other scientific and technological means to carry out field management in a refined manner.

In a wheat field in Changqing District, Jinan City, the green wheat seedlings are neat and evenly distributed and have good growth. Rows of drip irrigation belts are closely attached to the wheat roots, and are dripping water droplets slowly at a constant speed. The newly installed integrated water and fertilizer smart drip irrigation system this year can view and control the irrigation flow and water and fertilizer ratio in different areas of the wheat field with one click, making the wheat field spring pipe more accurate and efficient.

In another wheat field, plant protection drones are spraying drugs to prevent and control diseases and diseases. The pilots operate the controller circle to draw the corresponding range. The plant protection drone can automatically design the route and complete the spraying task accurately and efficiently, and spray more than 700 acres of wheat fields in one day.

This year, the area of ​​winter wheat in Changqing District, Jinan City reached 290,000 mu. After entering the wheat greening period, local agricultural technicians formed a spring management team to move the agricultural classroom to the fields, and guided farmers to do a good job in spring field management based on the wheat seedling conditions.

Henan: Wheat enters the stand-up period, agricultural technicians check the seedlings

At present, more than 85 million mu of wheat in Henan Province are entering the stand-up period one after another, which is also a key stage in water and fertilizer management. In Hua County, Anyang, Henan, farmers seized the farming season and carried out field management.

In a high-standard farmland in Duzhuang Village, Wangu Town, Hua County, large plant protection drones and self-propelled sprayers are efficiently carrying out fertilization and pest control operations. This year, the local area vigorously promoted the "drip irrigation + water and fertilizer integration" technology. The patch drip irrigation belt laid in the fields is like a "capillary", accurately delivering water and fertilizer to the roots of wheat seedlings. Compared with traditional irrigation, this model can save more than 30% of water and fertilizer.

The reporter learned from the Henan Provincial Department of Agriculture and Rural Affairs that this year, the province's wheat sowing area continues to stabilize at more than 85 million mu. In order to do a good job in spring wheat management, Henan sent 18 technical guidance groups to rural areas to provide specific technical guidance to farmers based on different seedling conditions.
