【技术实现步骤摘要】
本技术涉及一种施肥器,具体涉及一种能够精准控制施肥量的手动开合施肥器。
技术介绍
“精准施肥”的概念来源于精准农业。根据作物生长的土壤性状,分析作物的需肥规律,调节肥料的投入,充分利用土壤生产力,以最少的肥料投入达到更高的收入,从而提高化肥利用率,改善农田环境,增加农业种植效益。众所周知,我国目前的化肥当季利用率较低,实施精准施肥,按科学的方法种田,将会大大节省化肥用量,减少农业投入,增加种植效益。精准施肥的主要技术要点,采集和分析土壤养分,研究土壤施肥增产效应,拟定作物目标产量和需肥比例,配制肥料,确定施肥时期、地点和施用量,记载作物生长及产量变化情况。当然,要实现精准施肥还要用到特定的施肥器才能把肥料精准地施用到位。现有市面上的背负式施肥器缺点是肥料与打孔顶杆接触,在湿土和粘土中使用,肥料会粘在顶杆上,且下肥完不能盖土,手柄长短不能调节,下料管也不能调节,配件太多且不耐用,对使用人的操作要求高。
技术实现思路
为了克服现有技术的不足,本技术提供了一种手动开合施肥器,该施肥器设计合理,结构简单,不仅能够精准地控制施肥的用量,而且在肥料不会与菱形开合铲嘴粘连,从而可在湿土和粘土里使用。本技术解决其技术问题所采取的技术方案是:一种手动开合施肥器,其主要包括菱形开合铲嘴、加料管、下料阀、量杯、控料开关和手柄。上述菱形开合铲嘴安装在加料管的下端,所述加料管的上端为进料口,所述菱形开合铲嘴包括定铲嘴和动铲嘴,所述定铲嘴固定在加料管的下端一侧,所述动铲嘴铰接在定铲嘴上或者铰接在加料管下端的另一侧;所述下料阀固定在动铲嘴上,当动铲嘴张开时,下料阀同时向下打开;反 ...
