  种植莲藕:做那种防水层的藕池,一亩地要投资在五千元左右。一亩地一般能产5000-6000斤藕。
  种植莲藕:
  生长状况、抗御自然灾害和病虫危害的能力以及球茎的个数和重量。因此,培育荸荠健壮苗就成为夺取高产稳产的首要条件。
  1、严格选留种,保全苗作为种用荸荠必须在上一年植株生长的后期对地上部进行观察。将地上部群体生长整齐一致、无倒伏或倒伏轻微、无病虫危害的田块定为留种田,此为初选。荸荠收获时,从留种田中选外形圆整、表皮无破损、芽头粗壮、皮深褐色、单球茎重在15~20g以上、符合于所采用品种特征的球茎贮藏越冬,再进行复选。伏水荸荠4月中旬、晚水荸荠6月下旬至7月上旬进行催芽育苗时,从贮藏的荸荠中选择饱满、表皮光滑且色泽一致的球茎。皮色不一致的花荠通常是带病荠,应予剔除。将选出的芽头粗壮的种荠进行育苗,此为决选。
  2、药剂浸种浸根,育无病苗荸荠秆枯病是荸荠生产上的大敌,农民称为瘟病。常因此病的危害导致荸荠减产,严重者甚至绝产。种荠带菌是以后病菌扩展、蔓延的主要来源。若种荠带菌,在生长期中即使多次用药防治,也基本上效果甚微。而采用育苗前药剂浸种,栽植时用药浸根的方法,防病效果十分显著。具体做法是在育苗前用25%多菌灵500倍液浸种8~12h取出沥干,然后催芽育苗。栽植前用25%的多菌灵500倍液浸根16~24h。
  3、假植促根,育壮苗荸荠栽植后必须早发棵、早分蘖、早分株、早封行,才能早结荠,获高严。因此,栽植苗必须根系粗壮发达。假植是促进发根的有效手段。通常荸荠最初排种时球茎相距3cm,大约20~25天,苗高20~25cm时移苗假植1次,移苗距离放稀到12~15Cm,这样既利于发根,又扩大了苗的营养面积。移苗时发现病苗、瘦弱苗还可及时剔除。
  4、浅水薄肥,育大苗育苗期间尤其是伏水荸荠育苗期间温度不稳定,有时温度偏低,不利苗的生长。苗期灌浅水可以提高土温,促进苗的生长。一般在移苗之前灌水深1~2cm,移苗后,随着苗长大,气温也逐渐升高,灌水深掌握在2~3cm,最深不宜超过4cm。苗期追肥宜轻施勤施,当苗高10cm左右时浇稀粪水1次,随即浇水,以后每隔5~6天浇稀粪水1次。这样在栽植时苗高可达35~40cm,有的甚至达60cm以上,叶状茎粗0.5cm以上。
