In response to the bottleneck in the promotion and application of rice machine transplanting technology, we adopted advanced practical equipment and techniques for technology integration research such as high-speed sowing assembly line, high-speed conveyor belt, large mesh bag bracket, supporting varieties, low-cost substrate, medium arch double-layer covering insulation and large-scale seedling cultivation, etc., forming an efficient mechanical seedling cultivation and transplanting integrated technology system in Dongting Lake area. Compared with the original machine transplanting seedling cultivation technology, this integrated technology significantly improved production efficiency and significantly reduced seedling cultivation costs, which is suitable for large-scale centralized seedling cultivation in Dongting Lake area and similar areas.
