联合直播机主动防堵深施肥装置
本技术涉及农业机械
,具体地指一种联合直播机主动防堵深施肥装置。
技术介绍
化肥是提高作物产量、实现农业可持续发展的物质保证,施用化肥是最有效、最重要的增产措施。传统的地表撒施化肥或机播混施方式,大部分养分随地表径流、挥发而流失,肥料利用率低,盲目增加施肥量提高了生产成本,且造成严重环境污染。化肥深施是将肥料施到土壤特定层次,易于作物根系吸收利用的一项绿色生产措施,能够达到稳产、节肥、环保的节本增效综合效益。在联合直播机的应用上,施肥装置是实现施肥联合作业的重要部件。其中,施肥开沟器在土层运动,主要作用是将排肥器排出的肥料施入一定深度的耕层中。现有被动式防堵装置或主动式防堵装置通过抛、切、拨等作业形式对秸秆和杂草进行清理,但在实际作业时自身也会出现缠绕和堵塞现象,且主要适用于北方旱地作业,不适用于长江中下游地区稻茬田油菜小麦等作物播种时的深施肥作业。目前,我国长江中下游稻油轮作区稻茬田直播油菜、小麦时土壤黏重、秸秆量大,存在秸秆缠绕在开沟单体上或土壤-秸秆混合物黏附在施肥单体上,形成壅土堵塞造成播种机的通过性能差,施肥口被回流土壤堵塞造成肥料断条等现象,影响播种机作业性能质量。
