Mechanized rice direct seeding，which improves the level of rice mechanized planting，is a cost-effective and efficient approach for rice cultivation. Recently, rice direct seeding has rapidly increased owing to rural labour shortages and continuous increase of agricultural production cost. In this article,we analyzed the research and application progress of mechanized rice direct seeding at home and abroad, and introduced in detail the technical system and tools of rice precision hole sowing successfully studied by South China Agricultural University. The future research directions of rice precision hill-drop drilling technology and equipment were proposed.
