Research advances and prospects in the seeding technology and equipment for tray nursing seedlings of rice

After having gathered and summarized the technology and equipment for rice precision seeding of tray nursing seedlings at home and abroad, the paper summarized systemically the current research status of every kind machine type and analyzed particularly the technology difficulty in seeding, soil-spread and synchronous transmission of tray, and adopted work principles, technical parameters and performance index to be achieved, based on the structure characteristics and work principles of seeding pipelining. The application scope was confirmed by analyzing the characteristics of the existing machine types. A new type nursing seedlings system fitting for precision seeding supper hybrid rice was put forward based on the agronomic requirements of the rice planting and throwing transplanting and more especial supper hybrid rice planting technology in China. The above research provides technical references for traditional rice nursing seedlings and low cost, high velocity, precision tray nursing seedlings of developing supper hybrid rice.
