西藏河谷农区青稞轻简栽培技术规范

Technical Specification for Simple Cultivation of Highland Barley in Valley Agricultural Region in Tibet

西藏河谷农区青稞生产的耕整地、播种、植保、收获等关键环节已实现机械化或半机械化,在机械化耕整地或旋耕施肥播种、无人机或植保机械、机械化收获等方面集成先进适用机械装备和技术形成青稞轻简化栽培模式,“一江两河”流域的部分青稞生产示范基地实现水肥一体化管理,相较传统青稞生产实现了节约劳力和节本增效的比较优势。青稞轻简化栽培技术是我区青稞产业发展的必然之路,对西藏河谷农区青稞产业的发展具有重要意义。为适应当前青稞生产需要,本文从青稞选种与处理、耕整地与施肥、播种、田间管理、收获等技术要求方面阐述了适用于西藏河谷农区青稞生产的轻简栽培技术,研究制定了青稞轻简栽培技术规范,供青稞大田生产参考。

The key links of highland barley production in the valley agricultural region in Tibet had been mechanized or semi-mechanized.The simplified cultivation mode of highland barley had been formed by integrating advanced applicable mechanized equipment and technology in mechanized land preparation or rotary tillage fertilization and sowing,unmanned aerial vehicles or plant protection machinery,mechanized harvesting,etc.Part of highland barley production demonstration bases in the“one river and two rivers”basin had realized the integrated management of water and fertilizer,which had achieved the comparative advantages of saving labor and saving costs and increasing efficiency compared with traditional highland barley production.The simplified cultivation technology of highland barley is the inevitable way for the development of highland barley industry in this region,and it is of great significance to the development of highland barley industry in the valley agricultural region in Tibet.In order to meet the current needs of highland barley production,this paper expounds the light and simple cultivation technology suitable for the production of highland barley in the valley agricultural region in Tibet from the aspects of technical requirements such as selection and treatment,land preparation and fertilization,sowing,field management and harvesting,and studies and formulates the technical specifications for the field production of highland barley.
