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。此前,本申请人已经就相关技术提出了多件专利申请,例如:手动开合施肥器及其使用方法(申请号:201510797640. ...
