　　Sow a grain of millet in spring, harvest ten thousand in autumn.

At present, more than 700 million mu of grain has been sown in the country, accounting for more than 70% of the intended area, and the progress is faster than the same period last year.

　　On May 20, the national summer harvest meteorological service was fully launched, bringing a successful conclusion to the previous stage of spring sowing.

　　Spring agricultural production has a bumper harvest throughout the year. The meteorological department has deployed ahead of schedule, increased investment in science and technology, strengthened the application of new technologies and new means, and implemented refined agro-meteorological services by region, crop, disaster, and link, in order to lay a solid foundation for the whole year. The "first battle" of grain production, building a "ballast stone" for food security and contributing meteorological forces.

　　Science and technology "strong seedlings" smart farming promotes weak to strong

　　Grain harvests year after year, not to sit back and relax.

"A few years ago, the wheat fields here were still 'a needle', and after watering and fertilizing, they looked the same every day," said Geng Libin, director of the Agricultural Technology Extension Station in Junxian County, Hebi City, Henan Province.

In the summer of 2021, Junxian County was severely affected by rainstorms and floods, and then was affected by rare autumn floods, resulting in prominent waterlogging disasters in some winter wheat areas, significantly delayed winter wheat planting, insufficient accumulated temperature before winter, and a large proportion of late weak seedlings.

　　Since the beginning of spring this year, helping winter wheat "promote the weak and become strong" has become the top priority of agricultural meteorological personnel.

In order to let wheat "eat" and customize "nutritious meals", this year, satellite remote sensing has become the "eyesight" for monitoring the condition of winter wheat seedlings.

　　On April 6, in a green wheat field, agricultural meteorologists from Tangyin County, Anyang City were busy measuring the wheat planting area and collecting inspection samples for the satellite remote sensing monitoring and evaluation business of winter wheat distribution.

The four-level linkage of the meteorological department has applied satellite remote sensing technology to monitor and evaluate the distribution of winter wheat for the first time. The spatial resolution of the monitoring products reaches 30 meters, and the growing situation of wheat and soil moisture can be dynamically grasped, so as to provide solutions for the “strong seedlings” of science and technology.

　　Not only in Henan, but also in the main winter wheat producing areas, the late sowing caused by the severe autumn flood is a new challenge faced by all regions.

The Shaanxi Meteorological Department established a meteorological science and technology service team to use multi-source satellite data to carry out refined business services for the monitoring of winter wheat growth (miao condition); ”, a special person is in charge of the spring weather service.

　　War "epidemic" spring ploughing is correct

　　In early March, the epidemic hit like a "cold spring", and Jilin, a major food province, pressed the "pause button".

Spring ploughing is imminent, and farming is not waiting.

　　In the face of the new challenges brought by the epidemic, the "army and horse" of agricultural materials and agricultural tools have not been moved, and the meteorological service will be online first.

Jilin Provincial Meteorological Department and Department of Agriculture and Rural Affairs jointly issued spring plowing and spring sowing reminders through the "Ji Shi Office" column of the provincial epidemic prevention health code; organized a series of online training to deliver "meals" on demand.

　　"Since I followed the WeChat public account of the Bureau of Meteorology and planted seeds every day based on the weather information, it has given us peace of mind." Bai Xiwen, a farmer in Xinwanfa Town, Fuyu City, Jilin Province, said that before the arrival of the precipitation, he had completed the planting of all corn in the field. Sowing the seeds and now mulching the peanuts.

　　"The seedlings are really good, and there is no shortage of seedlings at all!" Kou Hongzhuan, head of the Donghe Rice Farming Farmers Professional Cooperative Association in Qing'an County, Suihua City, Heilongjiang, was overjoyed when he looked at the earliest rice seedlings planted on the black soil.

　　Under the guidance of the meteorological department, local farmers tried to adopt the rice super-early pot cultivation technology to raise seedlings in advance, which was 15 days earlier than the middle-ripening varieties.

This is equivalent to "grabbing" enough accumulated temperature, which satisfies the heat demand for rice growth to the greatest extent and accelerates the process of seedling raising.

　　This is just one of the silhouettes of the fine-to-grid Agrometeorological Service on black soil.

In the face of the new situation and new requirements of grain production, the National Meteorological Center has established a Chinese agricultural meteorological business system, and issued rolling updated grid-based agricultural weather forecast guidance products to the meteorological bureaus of 31 provinces (autonomous regions and municipalities directly under the Central Government) daily, so as to adapt measures to local conditions in Northeast China. Provide support for the development of sub-regional, sub-crop and sub-disaster service guarantees.

　　For the black land, in addition to continuing to stabilize the grain "ballast stone", this year must also play two important roles - the "main force" of soybean "supplementary short board" expansion tasks.

The "stabilizer" of corn production.

Meteorological departments in various places have issued practical measures to provide scientific and technological support for farmers to scientifically adjust their planting structure in a timely manner and increase and stabilize production.

　　"Planting corn or soybeans, the weather expert's words gave me the courage to make up my mind." Shao Guangjin, a farmer in Hailun City, Heilongjiang Province, has been entangled between the two crops. It was the meteorological expert who told him that the local climatic conditions were suitable for soybean planting, so he made a decisive decision. selected.

　　"The meteorological department helped us quickly identify areas suitable for soybean planting, which is conducive to comprehensively promoting the compound planting model," said Zhang Jinsuo, director of the Agriculture and Animal Husbandry Technology Promotion Center of Xing'an League, Inner Mongolia Autonomous Region.

　　This year, the tasks of clearing and expanding 3.5 million mu of soybeans in Inner Mongolia Autonomous Region and 1.6 million mu of compound planting have been gradually decomposed to various places.

According to the urgent needs of compound planting, the Meteorological Bureau of Xing'an League analyzed the agricultural meteorological conditions and the climatic zoning data of soybean planting in the past 30 years, and put forward suggestions for soybean expansion, which solved the urgent need.
