AbstractThis paper systematicallysummarized the key cultivation techniques and demonstration outcomes of high yield selenium-enrichedrice production in Shitai County，Anhui Province.Thekeycultivation techniques include selecting selenium-enriched rice varietiessuch as Zhuliangyou 57O，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 densityadjusted according to varietal characteristics （1.O5 million plants/hm 2 for hybrid rice，1.20 million plants/hm 2 for conventional rice）; applying selenium-enriched organic fertilizers to supplement selenium content，andadopting ashallow-wet-dryalternating irrigation mode tooptimizesoil conditions;controlling weeds， including grasses and broadleaf weeds， through manual removal and chemical applications （ 30% bensulfuron-methyl+ pretilachlor）;implementing integratedpest managementusingphysical （traps），biological （natural enemies），and chemical methods （ 6% kasugamycin） to control diseases and pests such as rice blast and brown planthoppers; harvesting when rice paniclesreach 85%-90% maturity and grain moisture content is between 18% and 20% ，and storing grains at temperatures of 10-15 ∘C and humidity levels of 65 % -75%;and incorporating impurity removal and color-sorting processes during post-harvest processing toimprovericequality.From 2023 to2O24，andtheyield，production input ratio，andseleniumcontentof ricewillallbe improved.Thisstudyprovidesareferenceforthegreenand efficient production of selenium-enriched rice.
