How to build a greenhouse fish pond greenhouse fish how to build

1, focusing on people, money and materials for the construction of key areas of the fishing pond; construction of a completed one, pay special attention to the shaping of the fishing pond and tamping. To avoid blindness in the construction of construction, the spread should not be spread too large, or built half-raised project, production and business activities can not be carried out.

2, the shape of the fishing pond project is often rectangular, pit pond type, in order to give full play to the three-dimensional benefits of aquaculture water. A single fishing pond area of about 10 acres, the pool depth of 2.5-3 meters, aspect ratio of 5:3, slope coefficient of 2-3, the ridge width of 5-10 meters, each fishing pond dug amount of about 5000-6000 cubic meters. Fishing pond construction modeling can be the first easy and then difficult to engage in some transitional fishing ponds, such as, "back" type, "high and low type", "well" type, "field" type and other shapes. "They are especially suitable for the construction of fishing ponds in low-lying lakes, swamps and mudflats. Among them, the "back" type fishing pond is the most ideal transitional fishing pond.

3, a complete water intake and drainage system should include pumping stations, pumps, water intake channels and other water intake systems, as well as culverts, drainage ditches, drainage gates and other drainage systems. In addition, there is a combination of intake and drainage system set up to stop fish facilities. After the beginning of spring, the construction of the fishing pond project is tight due to time constraints, and the aquaculture production season is imminent, so it is required to seize the construction of key parts in the overall deployment and arrangement of the project, such as synchronizing the drainage and irrigation system with the construction of the fishing pond. In the planning and design, the location of drainage and irrigation ditches is reserved. In the specific construction of the construction, focus on the construction of good stereotypes of fishing ponds, branch ditches, bucket ditches. The main canal, dry ditch and drainage ditch can be simple, leaving the project to be completed when the construction of good. In the form of construction and materials, the use of nullah form, positioning, stereotypes of the channel can be used in masonry materials; not positioning, stereotypes of the earth with the channel. For the construction of fish stopping facilities, it is best to use steel made of fences, the basic requirements are (fish) to stop, (water) flow smoothly, anti-(wind and wave) impact.
