Terraced fields are important farmland resources in mountainous and hilly regions. However, in recent years, rice cultivation in terraced fields has encountered a series of issues, such as low economic returns, a shortage of rural labor, inadequate mechanized supporting facilities, and poor irrigation conditions, which have resulted in the inefficient utilization of a large amount of terraced field resources. The technology for raising seedlings in bowl trays and simplified throwing-transplanting of rice in terraced fields fully leverages the ecological advantages of mountainous terraced fields and takes high-quality rice varieties as the foundation, utilizes factory-based bowl tray seedling production and supply along with simplified throwing transplantation methods, effectively enhancing labor productivity and reduces labor intensity. Meanwhile, this technology, combined with scientific fertilizer and water management as well as green pest and disease prevention and control measures, ensures stable rice yields and improves rice quality. Additionally, by optimizing storage and processing steps and engaging in brand marketing, it extends the industrial chain and enhances the value chain. This technology has achieved remarkable economic, social, and ecological benefits and is suitable for promotion and application in the hilly and mountainous regions of Southern China.
