Mechanized rice direct seeding is a cost-effective and efficient approach for rice cultivation. Recently, the use of rice direct seeding has been increasing rapidly owing to rural labour shortages and continuous increases in agricultural production costs. This article reviews the research and application progress of mechanized rice direct seeding including direct seeding technologies, precision rice seeding, precision rice seed-metering devices, key supporting agronomy technologies for… 
DESIGN AND PERFORMANCE TEST OF DIRECT SEED METERING DEVICE FOR RICE HILL
In order to meet the requirements of rice field precision direct seeding in rows and hills, a spiral grooved seed metering device for rice field precision direct seeding in hills is designed. The
