Recently, the industry standard "Technical Regulations for Factory Seedling Raising of Green Onion" undertaken by Shandong Wohua Agricultural Technology Co., Ltd. has been successfully authorized by the Ministry of Agriculture , which is the first case in Anqiu Agriculture. If this technical regulation is successfully implemented and popularized in the future, it will fill the gap of domestic industry standards for factory seedling raising of scallion, provide strong technical support for intensive and standardized seedling raising of scallion, and provide industry reference for the further development of the national scallion industry.
