气流输送式条播机现状及我国应用情况分析

摘要

气流输送式条播机具有减少钢材使用量、增加作业幅宽和提高作业效率等优点，是未来条播机主要发展机型。为此，对气流输送式条播机的国内外技术现状、种类及在我国应用中存在的问题进行了分析。结果表明：国外气流输送式播种技术已经成熟并广泛应用，我国仅处于实验室研究阶段，试制产品还未推广应用，且对技术的理论研究很少。%Air seed drills have many advantages which can reduce the use quantity of steel , increase working width , im-prove efficiency etc .It will be the main form of future seeders .The current research status at home and abroad , classifi-cations and problems existing in China of air seed drills were analyzed .Analysis showed that the technology of air seed drills at abroad had been very successful and widely used .However , the study in China was still in laboratory stage , the product had not been applied , and it lacked of theoretical study .
