Abstract: Nutritional soil used for raising seedling by mechanical rice transplanting in Hainan is laterite or the mixed soil with loess and sandy as the basic soil, adding a variety of seedling strengthening agent. It is not only high cost but also faced with serious problems like supply and freight of nutritional soil. In this paper, we took mud (paddy soil) as nutritional soil, referred to mud raising seedling technology at home and abroad, was grounded on labor saving, effort saving and cost saving, combined with the special climate conditions in Hainan, set an matching technology for mud raising seedling used mechanical rice transplanting by field experiments for many times.
