CCTV News (News Network): At present, national grain production has entered a critical period. All regions seize the farming season and empower science and technology to lay the foundation for a bumper grain harvest.

At present, winter wheat in various places has entered the grouting period one after another. This year, the winter wheat planting area in Hebei is more than 33 million mu. In Handan, the local intelligent field monitoring station has achieved the transformation from "experience farming" to "data farming". Agricultural technicians provide farmers with accurate "one spray and three prevention" operation guidance through the seedling conditions and soil moisture conditions displayed on the data platform. More than 36 million mu of winter wheat in Jiangsu have entered a critical period of pest control. In Dongtai, relying on the smart farm service platform, farmers have real-time monitoring of wheat insect situations to achieve unified prevention and control. At present, more than 400 unmanned plant protection machines have been invested in the city to carry out flight prevention operations. In Hejin, Shanxi, the plant protection drone has installed dual centrifugal spray heads to make the atomization of the medicine liquid more finely, which is conducive to the absorption of wheat leaves.

The sowing of crops such as corn in Northeast China has reached its peak. At present, the corn planting in Jilin Province has been more than half. In Tongyu, the seed machine equipped with a navigation system runs back and forth. This year, Tongyu has promoted precise dense planting technology on a large scale to improve the survival rate of corn. In Fuyu County, Heilongjiang, the local area adopts the integrated water and fertilizer planting model of large ridges and double rows to increase crop yields. The sowing of corn, soybean and other dryland crops in the province has exceeded 49 million mu.

The transplantation of southern rice is accelerated. Chongqing Rongchang, Sichuan Dazhou and other places vigorously promote mechanized rice transplanting, which not only greatly improves operating efficiency, but also makes the seedlings' plant spacing and row spacing more standardized, which is conducive to the later ventilation, lighting and growth of seedlings. The newly introduced super hybrid rice in Honghe, Yunnan this year has begun to be transplanted on a large scale. Compared with traditional rice varieties, super hybrid rice has large ears and many grains, which has strong resistance to lodging, and can effectively increase rice yield. Nanchang, Jiangxi Province processes rice straw into degradable fertilizers for seedling cultivation, which is not only green and environmentally friendly, but also reduces the cost of seedling cultivation, and the seedlings cultivated are also thicker. At present, the early rice planting area in Jiangxi Province exceeds 18 million mu.
