2026-09-18 Rice Paddy Soil Fertility Maintenance and Productivity Improvement Dataset doi:10.57760/sciencedb.iga.01256 en To address the prominent challenges in the major rice-producing areas of Liaoning Province — including large disparities in soil organic matter accumulation and depletion, insufficient utilization of resources such as water, fertilizers, and pesticides, and the low value-added of rice products — a "Rice Paddy Soil Fertility Conservation and Quality-Efficiency Enhancement Model" was developed with "soil fertility improvement, resource use efficiency enhancement, and grain quality upgrading" as the core technical pathways. Shenyang Shenbei New District was designated as the core demonstration area, with other major rice-producing regions serving as radiation zones. This dataset was constructed around the establishment and evaluation of the aforementioned model, and encompasses four components: (1) baseline soil data from the ten-thousand-mu demonstration area (Dataset 1); (2) high-throughput qPCR chip data of soil microbial communities following full-quantity in situ incorporation of rice straw (Dataset 2); (3) measurement and evaluation data on technology application effects in 2023 (Dataset 3); and (4) measurement and evaluation data on technology application effects in 2025 (Dataset 4). The key technologies involved include multi-pathway efficient organic material incorporation techniques (in situ straw incorporation, composting-based incorporation, and biochar-based incorporation), stabilized rice-specific fertilizer application technology, mechanized transplanting with simultaneous side-deep fertilization technology, and integrated water-saving and pest/disease management technology. The dataset comprises 4 files, all in Excel format, with a total data volume of 504 KB.
