原粮供应链是粮食供应链的重要组成部分，我国原粮供应链在选种、种植、归集、干燥、储存以及销售（流通）各环节都存在不同程度的品质风险和损耗浪费。本文在原粮供应链视角下，通过列举原粮品质指标及其质量控制环节，分析不同环节与主体存在的品质风险，并提出对原粮品质风险进行有效控制：一是要从育种研发端着手化解原粮品质风险；二是要建立政府主导、社会参与的原粮供应链品质风险防控机制；三是要加快制定相关作业标准与技术规范，深化产业应用。

The raw grain supply chain is an important part of the grain supply chain, and there are quality risks and wastage in various aspects of seed selection, planting, collection, drying, storage and sales (circulation). From the perspective of raw grain supply chain, this paper enumerated raw grain quality indicators and quality control links, analyzed the quality risks existing in different links and subjects, and put forward effective control of raw grain quality risks. Firstly, it was necessary to solve the raw grain quality risks from the breeding research and development side. Secondly, it was necessary to establish a quality risk prevention and control mechanism of raw grain supply chain led by the government and participated by the society. Thirdly, to speed up the development of relevant operating standards and technical specifications and deepen industrial applications.
