Reservoir flowing water culture largemouth bass and vegetable-rice planting cooperation method

Abstract

The invention discloses a cooperation method for reservoir flowing water culture of largemouth bass and vegetable-rice planting. The method comprises the following steps: (1) selection of a culture area site; (2) building a culture area; (3) constructing a hydroponic ditch; (4) cleaning and disinfecting the pond; (5) stocking fish fries; (6) breeding management; (7) hydroponic planting and water quality regulation and control; (8) fishing and marketing. Tail water, excrement and residual feed which are rich in nutrient substances such as nitrogen and phosphorus and are produced by weever culture are discharged into the water culture ditch under the driving of the gravity of flowing water of the reservoir. After being digested and absorbed by hydroponic vegetables and submerged plants, the water-soluble fertilizer can reduce the level of nutrient elements such as nitrogen and phosphorus to a proper level, can be directly supplied to rice for irrigation, and provides fertility for rice growth. According to the method, the unit area breeding yield of the largemouth bass is increased, crops such as high-quality vegetables and rice are produced, fish-vegetable-rice cooperation is formed, the comprehensive benefits of breeding are increased, land resources are saved, fusion of breeding and planting is promoted, and green, low-carbon and efficient breeding and breeding cooperation is achieved.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a collaborative method for culturing largemouth bass in flowing water in a reservoir and planting vegetable rice. Background technique [0002] Largemouth bass is very popular among consumers because of its delicious meat and no intermuscular spines. It is the characteristic freshwater fish species with the highest aquaculture volume in my country, and its aquaculture production is increasing year by year. At present, there are traditional pond aquaculture, large water surface cage culture and the latest factory culture. Traditional models such as pond culture and large-surface cage culture are limited by aquaculture production and large-surface ecological environmental protection factors, and have limited development space. New models such as factory farming require large investment, high technical requirements, and high operating costs and consumption of electr...

Problems solved by technology

[0003] In order to solve the defects of the prior art, the present invention provides a cooperative method for cultivating largemouth bass with flowing water in a reservoir and planting vegetables and rice. On the one hand, the cultivation output per unit area of ​​largemouth bass is improved, and on the other hand, high-quality vegetables, rice, etc. are also produced. For crops, form a "fish-vegetable-rice" collaboration, increase the comprehensive benefits of farming, save land resources, promote the integration of farming and planting, realize green, low-carbon and efficient farming collaboration, and overcome the current low density of largemouth bass farming, which is prone to disease, The survival rate is low, the benefit is not high, and there are many insufficient problems such as electricity, ponds, and waste of land resources.
