小龙虾养殖技术之稻田如何套养小龙虾

发布日期:2016-07-27 作者: 点击:

     龙虾苗


       稻田微孔增氧养殖龙虾苗是利用稻田的浅水环境,辅以人为增氧措施,既种稻又养虾,以废补缺、化害为利、互利助长,以提高稻田单位面积效益的一种生产形式。 2008年我们在前锋镇淮胜村利用60亩稻田开展微孔增氧养殖龙虾苗,取得了每亩产成品虾139.6kg、稻谷465.4kg,每亩利润达2402.8元的优异成绩。现将其情况介绍如下:

  1.2 TIANJIANGONGCHENGJIANSHE 

  稻田田间工程建设包括田埂加宽、加高、加固,进排水口设置过滤、防逃设施,环形沟、田间沟的开挖,建人造洞穴,安置遮荫棚等工程。沿稻田田埂内侧四周开挖环形养虾沟,沟宽3~5m,深0.8m,坡比为1:2.5,同时在田中问开挖“十、井”字形田问沟,田问沟宽1m,深0.6m,环形沟和田间沟面积约占稻田面积20%左右;利用开挖环形沟壑田间沟挖出的泥土加固、加高、加宽田埂,平整田面,田埂加固时每加一层泥土都要进行夯实,以防以后雷阵雨、暴风雨时使田埂坍塌,如有条件最好用塑料薄膜覆盖田埂内坡,以防小龙虾种苗打洞逃逸。

  微孔增氧设备由增养机、主管道、砂头管和砂头组成。在稻田四周设置直径4cm的大管道,在田问沟设置直径lcm的小管道并与罗茨鼓风机连接好,功率配置为 0.1kW/亩。增氧机固定在铁架上,远离稻田放置,开机时以不影响小龙虾苗种活动为宜。在生产季节,增氧机一般阴雨天24小时开机,晴天下半夜开机6小时(午夜12:00~凌晨6:00),具体开机时间和长短还要根据龙虾的存塘量、健康情况和水质等因素综合考虑。

  施药。原则上能不用药时坚决不用,需要用药时则选用高效低毒的无公害农药和生物制剂。施农药时要注意严格把握农药安全使用浓度,确保龙虾的安全,并要求喷药于水稻叶面,尽量不喷入水中,而且最好分区用药。分区用药的含义是将稻田分成若干个小区,每天只对其中一个小区用药。一般将稻田分成两个小区,交替轮换用药,在对稻田的一个小区用药时,小龙虾幼苗可自行进入另一个小区,避免伤害。水稻施用药物,应严禁使用含菊酯类的杀虫剂,以免对龙虾造成危害。喷雾水剂宜在晴天露水干后或下午进行,因稻叶下午干燥,大部分药液吸附在水稻上。同时,施药前田间加水20cm,喷药后及时换水。
