  春耕春管时节,吉林地区的水稻育秧工作目前已经完成九成以上。在双辽市,吉林省单体面积最大的育秧工厂,利用智能设备使得育秧效率和管理更加高效。

  在双辽市双山镇秀水村,农户们正分工协作,进行秧苗铺盘、覆土等育秧工作。在当地,普通农户小规模育秧,大棚的面积大多是两三百平方米,而这座育秧工厂,占地面积达到了4万平方米,能实现集中连片育秧。在使用同款育秧机的前提下,免去了人工来回在多个大棚里转运育秧材料和设备的时间,作业效率可以提升3倍左右。

  再有两天时间,工厂将全部铺满育秧苗盘,经过25到30天的生长周期,可以产出超3000万株水稻苗,能满足大概350公顷的水稻种植需求。这样的育苗量,三天就可以完成。在接下来的秧苗生长阶段,田间管理只需要一个人就可以完成,大大降低了人力投入。

  效率提升了,育苗的质量怎么样?来看育秧工厂的第二个优势,实现统一管理。在育苗环节中,托盘底部需要先装上土,铺上种子后,再覆上一层土。在工厂里,这些土是非常有讲究的,按照农技专家的指导,育苗土是由有机质含量比较高的腐殖性物质、杀菌剂等复配而成,在保障秧苗养分的同时,减少病虫害的发生。在这样统肥统管的模式下,可以使每一粒种子均匀提质生长。

  俗话说苗好七分收,秧苗长得是否壮实,种子播种质量是第一关,田间管护也尤其重要。育秧工厂采取智能化管理,一个人一部手机就可以操控灌溉、温控系统,远程控制秧苗所需的光照、水分和肥料。工厂内的新型移动喷淋设施,可根据棚内湿度自动开合,能更精准地控制苗床的干湿度,为秧苗生长提供最适宜的水分。

  维护水利设施保灌溉

  细水长流润良田

  在湖北孝感,近日高温少雨天气叠加农田用水高峰,如何保障春灌供水?当地通过启动泵站抽水灌溉、修护水利设施等措施,让春耕生产“细水长流”。

  湖北孝感孝昌县王店镇种有油菜2.5万亩、小麦1.14万亩,连续的高温少雨天气让种植户很发愁。得知情况后,镇村干部和农技人员来到田间地头,与村民一起摸排处理。经过对周边地势、水源分布以及泵站设施的综合考虑,决定启动泵站从附近河流抽水灌溉,解决农田的用水问题。

  在安陆市接官乡长山村,当地干部群众正加紧维护当地的千口堰河,为灌溉“舒筋活络”,打通春灌“生命线”。

  接官乡新龙村,则制定详细的水稻育秧灌溉用水计划,有序做好各灌区的堰塘水储备,让每一亩农田都喝到饱。

  荔枝花盛开

  授粉采蜜两不误

  在广西北流市,近40万亩荔枝花陆续盛开,吸引了不少周边省份的蜂农前来,蜜蜂在采蜜的同时还能帮助荔枝花授粉,助力荔枝丰收。

  由于今年北流市的荔枝普遍开花良好,来自四川、贵州、云南等多地蜂农前来养蜂酿蜜,每位蜂农都带来超过100箱、上万只的蜜蜂。

  据了解,荔枝花是雌雄同株异花,蜜蜂是很好的授粉媒介,可以提高坐果率、确保荔枝丰收。

  北流市农业农村局高级农艺师韦伟:清明以后气温比较稳定,没有极端的高温,也没有极端低温,对荔枝授粉坐果非常有利。水肥管理和防病虫害这两点做好的话,今年荔枝丰收在望。

  海上春耕忙

  2000万尾大黄鱼开始“分家”

  海上也是一派繁忙景象。经过一年多的养殖,福建连江投放到海里的2000万条大黄鱼苗已长到100克到200克,为了让它们更好地生长,渔民们这两天开始在养殖渔排上忙着给鱼苗“分家”。

  这批正在分苗的大黄鱼,是连江县本土培育的“岱衢族”大黄鱼,总数量约2000万尾,是去年春季投放到定海湾塑胶渔排上养殖的。当时每条重约1克多,现在已经长到了100克到200克不等,分苗是为了让它们更好地生长。

  福建省连江县文湾村渔民卢统辉:分三档,大、中、小,放到不同的网箱来养,如果不分,如果投料下去,料全部都是大的吃走,小的就吃不到,所以说要分开不同的网箱养。

  除了给大黄鱼分档,渔民们还要将从小就混入网箱里的河豚、鲈鱼、鲫鱼等其它鱼类分拣出来。

  福建省连江县大埕村渔民陈群:鲈鱼在里面,会吃大黄鱼。还有河豚、大黄鱼的鳍、尾巴也会被它吃掉,长大后就不好看了,所以说通通都要清理掉这些。

  渔民们介绍,大黄鱼分苗之后,个头较大的会全部搬进深水网箱养殖,等养到一斤左右,再搬到深远海养殖平台进行类野化养殖,之后就可以上市出售了。新闻结尾 我决定去找我亲爸:电气工程师必知的电压应用技巧与实例!的相关文章
