山东青州:因地制宜开展水肥一体化技术推广与指导

2023-08-15 11:00

今年以来,青州市农业农村局不断探索研究适合青州市沿河两岸村庄设施大棚安装使用的水肥一体化技术模式,在谭坊镇摸索出两套适合当地发展的水肥一体化技术应用模式。通过技术培训、现场观摩、示范展示、发放资料、技术指导等形式在全市进行了大力推广。

一是简易模式,在棚头安装简单的配肥装置,给作物行铺设喷灌带或滴灌带,将肥料和水同时供给到作物根系,根据作物需水需肥量的多少,通过阀门控制水肥用时用量,较常规的畦灌省水省肥省力,作物缓苗时间短,苗齐苗全苗壮,为作物整个生育期生长提供全方位的水肥供应。

二是高端模式,采用基质栽培的轻简自控无土栽培技术模式,基质下面铺设铝箔锡纸隔离膜,起到承托基质的作用,且保水保肥防渗漏,特别针对种植年限10年以上的老棚,改造以后直接解决土传病害的问题和肥料随水下渗的问题,肥水利用率提高到90%以上,农药使用量减少80%,提高了作物品质,在一定程度上减轻了农业面源污染。

通过水肥一体化技术的应用,较常规施肥节肥30%-50%,节水50%-70%,节约大量的劳动力,提高了肥料利用率,提高作物产量20%以上,同时降低棚室湿度,减轻病害的发生,减少了农药的使用量,提高作物品质。上半年,新增水肥一体化技术应用面积1.08万亩。
