Embodiment Construction

[0025] Referring to Fig. 1, it is a schematic structural diagram of a control box for farmland drainage and drainage. There are several drainage notches 2 on the top of the main box body 3, and the several drainage notches 2 are specifically opened on the front side of the main box body 3 and the upper ends of the left and right sides of the main box body 3. The main box body 3 Drainage holes 6 are provided on the rear side of the main box body 3. On the outside of the left and right sides of the main box body 3, and at a position close to the bottom of the main box body 3, a side box body 7 is provided. The side box body 7 passes through the conduction hole. 8 is in communication with the main box body 3, and a drain hole 5 is opened near the center of the top surface of the side box body 7, and the top surface of the main box body 3 and the top surface of the side box body are respectively equipped with main box body cover plates 1 and side box cover 4. As can be seen from ...

Abstract

The invention discloses a control box for drainage and drainage floodwater in farmland, comprising main box body and side box body. Drainage hole is set on the back-side surface of main box body and side box bodies are set on the outer bottom position of two left-right side surfaces of main body box. The side box body is connected with main body box by guiding hole. On the upper end of side and left-right sides several drainage notches are set and floodwater drainage hole is set on the top of side box body. Cover boards are set on the top of main and side box bodies respectively. Automatic control system for soil surface water in farmland in the invention is formed as said control box for drainage and drainage floodwater in farmland is buried in the ridge of field near the drainage canal, the back-side face of main box body is towards the drainage canal, meanwhile drainage holes set on the back-side face is are connected with the drainage canal. The design and arrangement of reasonable structure can decrease the load of N, P nutrient elements in drainage. It is provided with extending and applying value widely in pollution control for national river network area.

Description

technical field [0001] The invention belongs to the technical field of farmland drainage, and relates to a farmland drainage and stain control box and an automatic field water control system using the farmland drainage and stain control box. Background technique [0002] Water pollution is a common environmental protection problem in all countries in the world. The pollution sources that cause water environment pollution can be divided into point source pollution and non-point source pollution. Among them, non-point source has become the primary pollution source of water environment, and has gradually received great attention from the environmental protection departments of governments in various countries. [0003] According to literature reports, non-point source pollution accounts for two-thirds of the total pollution, and the contribution rate of agricultural activities to non-point source pollution is as high as 75%. With the rapid development of my country's economy a...
