Abstract: The authors created and designed the reciprocating sowing machines in order to take place of the thinning out seedlings work-the traditional agricultural method of grain production. Through the theoretical analysis and the initial exploration of practical experiments, it is considered that seed-grain fixed planting and precision single seed sowing can be well realized by using reciprocating feeder applied to the precision seed-grain sowing machines, meanwhile the suffering of the handwork labor can be eliminated. Therefore reciprocating sowing machines have created excellent conditions for the spread of grain production and brought brand new future for the use of the precision seed-grain sowing machines in agriculture.
