胡麻作为甘肃中部地区主要油料作物之一，具有悠久的种植历史和显著的经济价值。旧膜免耕穴播技术一定程度上能保护土壤墒情，减少土壤水分蒸发，发挥保水抗旱功能。通过开展胡麻新品种陇亚31号配套旧膜免耕穴播技术示范，从品种选择、栽培与播种、播种后的田间管理以及适时收获等方面总结了胡麻旧膜免耕穴播技术，以期为甘肃中部寒旱区胡麻的提质增产提供技术指导。

Flax(Linum usitatissimum L.), a pivotal oilseed crop in the central Gansu region, boasts a long cultivation history and substantial economic significance. The no-till hill planting system with retained plastic film mulch demonstrates efficacy in preserving soil moisture, mitigating evaporation, and enhancing water conservation under drought stress. This study presents an integrated technology demonstration for Longya 31, a newly developed flax cultivar, aligned with retained film mulch-based conservation tillage practices. Key agronomic protocols are summarized across four domains: cultivar selection, cultivation and sowing, post-emergence field management strategies, and optimized harvest timing. The compilation aims to provide evidence-based technical guidance for enhancing flax yield and quality in cold and arid agroecosystems of central Gansu Province, as documented in relevant agronomic literature.
