摘　　要：与当地青稞传统生产模式作比较、试验研究集成合理密度、合理施肥、绿色防控与低损耗机械化生产于一体的轻简化青稞生产模式是西南区西藏河谷青稞主产区日喀则市节约劳动力投入,提高青稞优质与高效,降低播种和机械化收获损失率,扩大青稞轻简化示范面积,发展以轻简化栽培生产模式为主的青稞产业兴盛战略的势必走向。为印证青稞轻简化栽培生产模式在西南区西藏河谷区日喀则市的可操作性,2020—2022年在西藏河谷区日喀则市白朗县嘎东镇和白朗县洛江镇扎林村,与传统青稞生产模式为对照,对青稞轻简化生产模式进行了研究。结果显示,青稞轻简化生产模式与传统青稞生产模式相比,青稞各品种的株高、穗长等主要农艺性状变化不大;产量和品质差别不明显;但在用工投入上,轻简化生产模式节约劳动力达到了96.7%,每667 m2节本增效效果明显,适合在西藏河谷青稞主产区应用。Compared with the local highland barley traditional production model,the light simplified Highland Barley production model,which inte⁃grated reasonable density,reasonable fertilization,green control and low-loss mechanized production,is the inevitable trend of saving labor input,im⁃proving the quality and efficiency of highland barley,reducing the loss rate of sowing and mechanized harvest,expanding the demonstration area of highland barley,and developing the flourishing strategy of highland barley industry in the highland barley main producing area Shigatse.In order to confirm the operability of light and simplified highland barley cultivation production model in Shigatse,Tibet,Southwest China,compared with the tra⁃ditional highland barley production model,in Zalin village,Luojiang Town,Bailang County,Bailang County,Shigatse,Tibet,from 2020 to 2022,the light and simplified production mode of Highland Barley was studied.The results showed that compared with the traditional production mode,the main agronomic characters of highland barley,such as plant height and panicle length,had little change,the yield and quality had no obvious difference,but in terms of labor input,the light and simplified production mode can save labor force by 96.7%,which is suitable for the main production area of Highland Barley in Tibet Valley.
