我国春油菜产区以普通播种机条播为主,播种量大;精密播种在新疆示范,省种、增产显著,技术成熟,受到普遍欢迎,需广泛开展示范。冬油菜产区机械直播处于示范阶段,实用机型不多,价格昂贵,限制大面积推广,应开发实用型油菜精密播种机。本文介绍了几个型号的油菜播种机和精密排种器。 Spring rapeseed production areas in our country are mainly sowed by ordinary sowing machines with large sowing volume. Precise sowing is a demonstration in Xinjiang, provincial species, significant increase in yield, mature technology, generally welcomed, to be widely demonstrated. Winter rapeseed areas mechanical live in the demonstration stage, few practical models, expensive, limiting the promotion of large area, should develop practical rapeseed precision sowing machine. This article describes several models of rapeseed sowing machines and precision seed metering.
