Summary:The invention provides a seed metering mechanism and a seeder, and relates to the technical field of mechanical seeding. The seed metering mechanism comprises a roller, an air pipe, an air needle and an air distribution disc; seed needle holes are formed in the roller; the air pipe is arranged in the roller in a replaceable mode, and the air needle is arranged on the air pipe in a replaceable mode and located in the seed needle hole; the gas distribution disc is rotationally connected with the end part of the roller, and a negative pressure area and a positive pressure area are respectively arranged in the gas distribution disc; when the air pipe rotates to a negative pressure area, the air needle can adsorb seeds; when the air pipe rotates to the positive pressure area, the adsorbed seeds can be separated from the air needle. The seeder comprises a seeding mechanism. The seed metering mechanism disclosed by the invention can adapt to seed metering of seeds with different shapes and granularities by replacing
