In early July, amidst midsummer, the vast fertile fields of the Jiansanjiang Branch of the Beidahuang Group, spanning tens of millions of mu, are scenes of rice plants shooting up and forming ears.
As a national core demonstration zone for modern large-scale agriculture, Jiansanjiang is leveraging technology to empower industrial upgrading. By strengthening its "technology belt," utilizing "smart maps," and safeguarding the "black soil," it is transforming new quality productive forces into grain production capacity, striving with full force towards the challenging target of an annual output of 14 billion kilograms of grain.
Hailed as the core area of China's "Great Granary," Jiansanjiang is the country's largest, most modernized, and most comprehensively productive national-level crucial commodity grain base. In recent years, it has led the upgrade of modern agriculture with technology and empowered agricultural production with smart machinery, solidly reinforcing the "ballast stone" of food security.
Facing the task of increasing grain production capacity by "tens of billions of kilograms" this year, Jiansanjiang has established an agricultural technology demonstration belt stretching approximately 1,300 kilometers. This "technological artery" links 44 branch-level demonstration fields and 15 specialized demonstration zones, centrally showcasing over 20 core technologies and radiating across 1.26 million mu of black soil land.
Relying on a differentiated layout, Jiansanjiang has promoted digitalized smart irrigation districts and a "three precisions, three details, three increases" cultivation model adapted to cold-region planting. In 2025, the highest per-unit yields for rice, corn, and soybeans in Jiansanjiang reached 957.3 kilograms, 1,040.9 kilograms, and 320.8 kilograms respectively, achieving a "22nd consecutive bumper harvest."
To tackle the dual challenges of labor shortage and the need for increased production capacity, Jiansanjiang is steadfastly implementing a "storing grain in technology" strategy. In the fields, unmanned transplanters and intelligent harvesters enable multi-machine collaborative operations. In the cloud, a digital agriculture platform shares real-time farming data, shifting production decisions from "watching the weather" to "watching the screen."
In 2025, Jiansanjiang secured 8 national patents, saw smart agricultural machinery operate over 11 million mu-times, and achieved a comprehensive agricultural mechanization rate of 99.8%. This year, the branch has selected farms such as Qixing and Hongwei as pivotal points, focusing on multi-source remote sensing monitoring and unmanned variable-rate fertilization to propel smart agricultural machinery from "experimental display" to "practical production."
Regarding black soil protection, Jiansanjiang vigorously promotes the "Sanjiang Model," integrating key technologies like side-deep fertilization and full straw return. This combination punch of "reducing fertilizer and building soil health" has yielded significant results. For instance, the Honghe Farm alone achieved annual cost savings and efficiency gains exceeding 110 million yuan through black soil conservation measures. In 2025, its "1332 Water-Saving Model" was honored with the "First China Water Conservation Award for Advanced Collectives."
This year, based on a new stage of development, Jiansanjiang is utilizing technology to empower the upgrade of the agricultural industry, aiming for a "23rd consecutive bumper harvest" in grain production.
