Abstract: The difficulties of "soil fetching" and "disposal" of agricultural waste in rice seedling raising in China still exist. With the decrease of agricultural population year by year, the cost of traditional rice seedling raising, soil fetching and soil screening has increased, further reducing the farmers’ income from planting. Driven by many factors, the application of rice substrate based seedling raising technology in China has entered a rapid development period. This paper focuses on the operation process, operation methods The precautions and other aspects are described in detail to enable the majority of farmers and agricultural technicians to deeply, comprehensively and carefully understand the technology, with a view to providing application reference for the majority of rice farmers.
