Abstract

The invention belongs to the technical field of agricultural pollution prevention and control, and particularly relates to a facility agricultural pollution prevention and control type water and fertilizer cyclic utilization technology which comprises the following steps: 1, runoff diversion: firstly, carrying out farmland field investigation, understanding terrain, water source, drainage conditions and the like, designing a reasonable drainage system layout, and after the drainage system layout is completed, carrying out water supply according to a design scheme; the method comprises the following steps: constructing drainage facilities such as an ecological ditch and a rainwater collection pool, ensuring that the construction quality meets the standard, guiding runoff into a treatment area during rainfall or irrigation, setting monitoring points, regularly monitoring water quality change, regularly cleaning and maintaining the drainage facilities, ensuring the drainage facilities to be unobstructed, and preventing blockage and pollution. According to the facility agriculture pollution prevention and control type water and fertilizer cyclic utilization technology, a runoff flow guide process is set, topographic conditions can be utilized, a natural drainage system can be designed, and low-cost and efficient utilization of water resources is achieved.
