摘要（英）：

The invention provides a precision seeder which comprises a seed bin (4), a bearing seat (9) arranged in the seed bin (4), and a seeding rod (6) penetrating through the seed bin (4) and the bearing seat (9). One end of the seeding rod (6) is communicated with an air suction and blowing device (1), the other end of the seeding rod (6) extends out of the seed bin (4), a seed inlet (10) is formed inthe side wall, located in the seed bin (4), of the seeding rod (6), and a locking piece (8) used for controlling the opening and closing of the seed inlet (10) is arranged in the seeding rod (6); a one-way valve (11) is arranged in the seeding rod (6) and located below the seed inlet (10), a ventilation and quantification rod (2) is movably matched in the seeding rod (6), and a cavity (14) is formed between the ventilation and quantification rod (2) and the one-way valve (11). The precision seeder has the advantages that the seeding quantity of seeds can be controlled, and the structure is simple.
