Embodiment 1

[0092] 1. In 2013, it was successfully tested at the Ganning base of Wanzhou Fisheries Research Institute. The sunshade net was used as a floating bed, and a moso bamboo was added every 3 meters to increase the buoyancy. The sunshade net full of spinach seedlings is laid flat on the water surface of the pond, and the two ends are fixed on the embankment of the pond with thin ropes. The water spinach seedlings absorb nitrogen, phosphorus and other waste nutrients in the pond water to grow without fertilization, so as to improve the water quality of fishery.

[0093] 2. Promotion area

[0094] It is planned to promote 200 mu in Wanzhou District in 2014.

[0095] 3. Work measures

[0096] 1. In August 2013, the research team of "Pond Fish and Vegetable Symbiosis Water Quality Improvement" held an on-site training meeting for fish farming owners in Wanzhou District at the Ganning Base of Wanzhou District Fisheries Research Institute. 30 owners in the district participated in the...

Embodiment 2

[0111] Basic results of rice planting experiment on pond surface

[0112] 1. Rice yield:

[0113] 1.16# Pond: rice variety "Fengyouxiangzhan", transplanted seedlings on April 15, 2015, harvested on August 16, planted 624 square meters, accounting for 15% of the pond water surface, harvested 583 kg of rice, equivalent to 622.9 kg per mu. A total of 10 rows were planted, each row was 62.4 square meters, and the output of each row was shown in the table below.

[0114]

[0115] The technical parameter of Fengyouxiang accounted for production is 600 kilograms per mu. The yield of this trial exceeded its yield parameters.

[0116]1.25# Pond: transplanted seedlings on April 24, 2015, and harvested on August 20. There are a total of 6 rice varieties, 1-5 are Fengyouxiangzhan, and 6-10 are the regional test varieties of the Agricultural Commission Seed Station. Due to the rain and wind on August 18-19, rows 1-6 are high-stem varieties with a plant height of more than 1.3 meters...

Abstract

The invention discloses an ecological purifying system for a pond water body. The ecological purifying system for pond water quality comprises a shading net, a floating island and terrestrial plants, wherein the shading net is used for planting vine floating plants, the floating island is used for planting plants which cannot grow in a floating mode, traction ropes are tied to the two sides of the shading net, and a plurality of seedling growing pots are arranged on the floating island. A biological floating bed technology based on a floating bed plant system disclosed by the invention has multiple advantages of small investment, easiness to manage, no environment risk, good economical effect and the like, so that the biological floating bed technology can attract attention and has wide application prospect in aquaculture water body restoration. Controlling culture water body pollution, maintaining water body ecology balance and achieving water body virtuous circle are imperative; thus, the ecological floating bed technology has important theoretical and practical significance in healthy development of Chongqing aquaculture industry and sustainable utilization of resources.

Description

technical field [0001] The invention belongs to the technical field of pond planting, and in particular relates to a pond water ecological purification system. Background technique [0002] In recent years, with the continuous development of Chongqing's aquaculture industry, the intensive and high-density farming model has brought many new environmental problems while bringing substantial economic benefits. Aquaculture uses a large amount of feed while utilizing limited water resources, but the utilization rate of feed by farmed animals is very low, only 25% to 30% of the feed put in is used by farmed animals, and a large amount of excrement and feed residues are extremely high. Under the action of microorganisms, it is easy to decompose ammonia and nitrate, which are harmful to the survival of aquatic organisms, leading to eutrophication and deterioration of water bodies, and even the outbreak of various diseases. So far, there are three restoration methods, namely physica...
