This paper systematically summarized the key cultivation techniques and demonstration outcomes of high yield selenium-enriched rice production in Shitai County, Anhui Province. The key cultivation techniques include selecting selenium-enriched rice varieties such as Zhuliangyou 570, soaking seeds in warm water and applying chemical seed treatments to improve germination rates and control diseases; transplanting seedlings at the 3.5-leaf stage, with planting density adjusted according to varietal characteristics (1.05 million plants/hm2 for hybrid rice, 1.20 million plants/hm2 for conventional rice); applying selenium-enriched organic fertilizers to supplement selenium content, and adopting a shallow-wet-dry alternating irrigation mode to optimize soil conditions; controlling weeds, including grasses and broadleaf weeds, through manual removal and chemical applications (30% bensulfuron-methyl+pretilachlor); implementing integrated pest management using physical (traps), biological (natural enemies), and chemical methods (6% kasugamycin) to control diseases and pests such as rice blast and brown planthoppers; harvesting when rice panicles reach 85%-90% maturity and grain moisture content is between 18% and 20%, and storing grains at temperatures of 10-15 ℃ and humidity levels of 65%-75%; and incorporating impurity removal and color-sorting processes during post-harvest processing to improve rice quality. From 2023 to 2024, selenium-enriched rice cultivation practice will be carried out in Xiaohe Town, Shitai County. The planting cost will decrease from 17 175 yuan/hm2 to 12 150 yuan/hm2, the yield (from 7 950 kg/hm2 to 8 250 kg/hm2) and production input ratio (from 1.18 to 1.66) will increase in 2024 (after promoting high yield cultivation techniques) compared to 2022 (before promoting high yield cultivation techniques). This study provides a reference for the green and efficient production of selenium-enriched rice.
