往复式排种器用于谷子精密播种机的初探

为了取代谷子生产传统耕作方法中的间苗劳动，作者创新设计了往复式排种器应用在谷子精密播种机上。经过理论分析与实地试验的初步探索认为，在精密播种机上使用往复式排种器，可以很好地实现谷子的定植、定株精密单粒播种，从而取消了谷子间苗的手工劳动，为谷子生产推广创造了良好条件，为谷子精密播种机在农业生产中的使用带来广阔前景。

Reciprocating feeder applied to precision seed-grain sowing machines

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.
