Embodiment 1

[0055] Such as figure 1 , figure 2 Shown, utilize the method for ecological cultivation of aquatic vegetables and carp entering lake river water, comprise the following steps:

[0056] A, the construction of culture pond 1: build two-stage culture pond 1 on the gentle slope of lake 4 sides, the culture pond 1 water of the first level is connected with the river 2 water flowing into the lake, the culture pond 1 of the first level is at the height of the dam ridge There is an overflow 3 at the 50cm place, and the redundant pool water is discharged into the culture pond 1 of the second level through the overflow 3, and the culture pond 1 of the second level has an overflow 3 at the dam height of 50cm, and the excess water passes through the overflow Port 3 discharges into lake 4;

[0057] B, Aquatic Vegetable Cultivation: Floating planting devices are placed in the culture pool 1 of the first level and the culture pool 1 of the second level, and the floating planting devices a...

Embodiment 2

[0065] The method for ecologically cultivating aquatic vegetables and carp by using water entering lakes and rivers comprises the following steps:

[0066] A, the construction of culture pond: build two grades of culture ponds on the gentle slope beside the lake, the water of the culture pond of the first level is connected with the river water flowing into the lake, and the culture pond of the first level has an overflow at the ridge height of 60cm, redundant The pool water of the second level is discharged into the second-level aquaculture pond through the overflow port, and the second-level aquaculture pond has an overflow port at the height of the dam ridge at 60 cm, and the excess pool water is discharged into the lake through the overflow port;

[0067] B. Planting of aquatic vegetables: floating planting devices are placed in the first-level culture ponds and the second-level culture ponds, and the floating planting devices are arranged in parallel rows in the culture po...

Abstract

The invention relates to the field of sewage treatment characterized by ecological breeding, in particular to a method for ecological breeding of aquatic vegetables and carps through lake inflowing river water. The method comprises the following steps that (A), a breeding pond (1) is constructed; (B), the aquatic vegetables are planted; (C), the carps are bred; (D), the aquatic vegetables are harvested; and (E), the carps are caught. According to the method, agricultural chemicals and fertilizers are not used in the growth process of the aquatic vegetables. Pollutant in water can be effectively eliminated, and the fish growth can be ensured. Nitrogen and phosphorus in water bodies and silt are absorbed in the growth process of the aquatic vegetables, so that the phenomenon that the nitrogen and phosphorus migrate downstream is reduced. The aquatic vegetables can add the dissolved oxygen content in the water bodies and promote degradation of dissolved organic matter. The bred carps can eliminate plankton, and water quality is further purified; and meanwhile, the carps and the like are good aquatic products, and certain economic income can be acquired. The method for ecological breeding of the aquatic vegetables and the carps through the lake inflowing river water has good ecological benefits, economic benefits and social benefits.

Description

technical field [0001] The invention relates to the field of sewage treatment characterized by ecological cultivation, in particular to a method for ecologically cultivating aquatic vegetables and carp by utilizing the water flowing into lakes and rivers. Background technique [0002] In the past 30 years, the agricultural production in many lake runoff areas has undergone great changes in crop structure and layout with the adjustment of the planting structure. Rapid development. Compared with food crops, vegetables require a large amount of fertilizer, and the multiple cropping index is high, which will greatly increase the amount of fertilizer applied per unit of land area per unit of time, coupled with unreasonable fertilization by farmers, The soil nutrient structure is unbalanced, the residual nutrient increases, and it is easy to flow into the river (ditch) with the water movement. There are many main rivers in the lake runoff area, and the nutrients flowing into the...
