Black Soil Granary Whole-Region Customized Model Development and Demonstration Application Dataset

Guided by the "Third Law of Geography"—geographic similarity—and based on the degradation classification and grading of Northeast black soils and the knowledge graph of conservation technologies, this study conducts research on intelligent algorithmic decision-making for technology selection, provides tailored black soil conservation technical solutions for degraded areas, and selects representative degraded zones for field validation.

Leveraging the holistic customization model and integrated application platform for the Black Soil Granary, it carries out demonstration applications of optimized varieties, technologies, and models. It also conducts innovation and breeding of low-input, stress-resistant, high-yield crop germplasm resources and their extension; develops and demonstrates tillage techniques and models for different straw-returning methods in maize and rice; researches and demonstrates integrated pest, disease, and weed management and fertilizer reduction and efficiency enhancement for maize and rice straw return; innovates and demonstrates cropping models for optimal tillage and suitable planting, as well as coverage-based erosion-prevention planting on black soils; demonstrates integrated crop-supporting cultivation models for black soil conservation and fertility maintenance; and undertakes validation and demonstration of research outcomes from parallel projects.

By adopting rational technical pathways and scientifically effective methodologies, this study aims to achieve substantial breakthroughs in key technologies and the upgrading of integrated technologies, promote the implementation of core technologies for black soil protection, utilization, and health management, realize the conservation of black soil farmland, reduction of resource consumption, and improvement of farmland quality, safeguard national food security, agricultural product quality safety, and agro-ecological environmental security, and facilitate the sustainable agricultural development of the black soil region.
