Embodiment 1

[0030] Embodiment 1, Sedum notoginseng laboratory water purification simulation test

[0031] 1. Preparation of ecological floating bed

[0032] Use polyethylene foam board as the carrier of the ecological floating bed (such as figure 1 shown in A). The planting interval is 10 cm, and the hole diameter is 2 to 4 cm, which is just the right size for inserting the test plants.

[0033] 2. Planting of Sedum notoginseng seedlings on ecological floating beds

[0034] The cultivation of Sedum notoginseng seedlings adopts the cutting method of soil cultivation or hydroponic seedlings, and the vigorous plant branches are selected for direct cutting cultivation. When the temperature in the breeding pond is above 10°C and the seedling height reaches 10-15cm, select seedlings with strong plants, good growth and uniform size to transplant to the ecological floating bed in step 1. Carefully wash the sand with water, wrap the roots with spray-coated cotton, and place the cuttings on the...

Abstract

The invention discloses a method for ecologically remedying water by utilizing aizoon stonecrop. The method particularly comprises the following steps: planting aizoon stonecrop on an ecological floating bed; and placing into water to be remedied so as to ecologically remedy the water to be remedied. Nutrient substances such as nitrogen and phosphorus in culture water are absorbed by the aizoon stonecrop, so eutrophication of the water is avoided and the nitrogen content and the phosphorus content of the culture water are reduced; and economic benefit is obtained by harvesting and selling the aizoon stonecrop periodically. By the method, the problem that the culture water is deteriorated can be effectively solved and the culture ecological environment is recovered. Harmony and unity of environmental benefit and economic benefit are realized by harvesting the aizoon stonecrop to serve as a medicine material and high-economic-value vegetable.

Description

technical field [0001] The invention relates to a water body ecological restoration method, in particular to a water body ecological restoration method for aquaculture water by using sedum notoginseng. Background technique [0002] China is a big aquaculture country. In 2006, the output of aquaculture aquatic products in my country reached 3.6×10 7 t, accounting for 70% of the world's total output. Due to limited water resources, the breeding mode is mostly high-density farming, the aquatic animals are stocked at a high density, and the amount of bait fed is large. A large amount of residual bait, excrement, dead remains and other organic matter are easily accumulated in the aquaculture water body, resulting in aquaculture. The content of total nitrogen, total phosphorus, ammonia nitrogen and nitrite in the water body exceeds the standard, harmful bacteria grow in large numbers, the physique of farmed animals declines, and the ability to resist stress is poor, which may eve...
