Rice field water inlet and drainage system, rice field system and rice field water inlet and drainage control method
The invention discloses a rice field water inlet and drainage system, a rice field system and a rice field water inlet and drainage control method. The rice field water inlet and drainage system comprises a first communication assembly, a second communication assembly, an impermeable film layer, a filter material layer, a protective layer, a partition plate and a mound ridge. The impermeable film layer is used for being arranged on the inner wall of a groove surrounding the rice field and reaching the depth of a new soil layer, the groove is filled with the filter material layer and wrapped by the impermeable film layer, the protective layer covers the top face of the filter material layer and is in sealed connection with the impermeable film layer, and the impermeable film layer and the protective layer seal the filter material layer. The partition plate is arranged in the filter material layer and connected with the impermeable film layer and the protective layer in a sealed mode so as to partition the filter material layer, the mound ridge is piled on the protective layer and higher than a plowing layer in the rice field, and the first communication assembly and the second communication assembly are used for achieving water inflow and drainage between the rice field and the ditch respectively. The method is low in cost, easy to implement, environmentally friendly, good in effect and capable of delaying runoff and nitrogen loss time of the rice field under the rainstorm condition and increasing interception of nitrogen.
本发明公开了一种稻田进排水系统、稻田系统以及稻田进排水控制方法。稻田进排水系统包括第一连通组件、第二连通组件、防渗膜层、滤料层、保护层、隔板以及土堆田埂。防渗膜层用于设置在围绕稻田四周且深度抵达新土层的凹槽的内壁，滤料层填充于凹槽内并被防渗膜层包裹，保护层覆盖于滤料层的顶面并与防渗膜层密封连接，防渗膜层与保护层密封滤料层，隔板设置在滤料层内并与防渗膜层、保护层均密封连接以将滤料层隔断，土堆田埂堆砌于保护层并高于稻田内耕作层，第一连通组、第二连通组件分别用于实现稻田与沟渠之间的进排水。本发明成本低、易实施、环境友好、效果好，能够延缓暴雨情况下稻田径流和氮素流失时间，增加对氮素的截留。
