Problems solved by technology

[0002] In southern prawn farming, from mid-to-late November to mid-April of the following year, the climate is changeable and the temperature is unstable, causing the outdoor time to exceed 4 months and normal farming cannot be carried out, so the shrimp farming ponds have been idle for at least 100 days , the means of production cannot be rationally utilized, resulting in a waste of resources; in addition, because the current prawn farmers mostly adopt the traditional aquaculture structure for prawn aquaculture production, resulting in no fresh and live shrimps on the market from the end of January to May, and there is not enough shrimp in the market. Supply of fresh and live prawn products

specific Embodiment 1

[0025] A method for cultivating prawns in an overwintering shed, comprising the following steps:

[0026] (1), build the overwintering shed breeding pond;

[0027] The construction of the overwintering shed breeding pond: such as Figure 1 to Figure 2 As shown in the wintering shed cultivation pond, the cultivation pond is preferably 6 to 8 acres of area. The bottom 1 of the breeding pond is laid with a central sewage discharge pipeline 6 and an oxygen supply pipeline 2, and the oxygen supply pipeline 2 is connected with the oxygen increasing device outside the pond. The aeration device is composed of a blower, a main air pipe, a number of buried branch air pipes and a number of stomata pipes. The buried branch air pipes are evenly distributed under the plastic film at the bottom of the pool. The distance between every two adjacent branch air pipes The same; the stomata tube is installed on the branch air pipe, the distance between every two adjacent stomata pipes is the sam...

specific Embodiment 2

[0038] Compared with the specific embodiment 1, in this embodiment, the culture pond is to combine two culture ponds of 3 to 4 mu, and the overall culture pond area is preferably no more than 8 mu, so as to facilitate the firm structure of the greenhouse and the cultivation management. For convenience, a wintering shed is erected above the two breeding ponds. The erection method of the wintering shed is similar to the specific embodiment 1, but the stake material of the wintering shed can also be made of bamboo poles with the same thickness as possible, or high strength and corrosion resistance. Good performance steel pipe construction. In addition, hemp rope or nylon rope can also be used to bind the stakes instead of the steel wire used in the embodiment.

[0039] In addition, in this embodiment, the beneficial microorganism preparation can also be a beneficial microorganism preparation containing 1 billion photosynthetic bacteria per gram, which is applied to the culture po...

specific Embodiment 3

[0040] Compared with specific embodiment 1 or embodiment 2, in this embodiment, the beneficial microbial preparation adopts specific embodiment 1 and specific embodiment 2 containing bacillus 2 billion / gram, containing photosynthetic bacteria 1 billion / gram and containing lactobacillus 1 billion / gram of three kinds of beneficial microbial preparations used alternately. All the other breeding processes are the same as in the specific embodiment one.

Abstract

The invention relates to a culture method of penaeid shrimps in an over-winter shed, which comprises the following steps: building up a culture pond of the over-winter shed; discharging sea water into the culture pond after treatment, culturing water color of culture water, and then pouring shrimp fries into the culture water for culture; applying a beneficial microorganism preparation during the culture period for degrading pollutants produced during the culture process and conditioning water quality; regulating water temperature of the culture pond by opening small doors at two sides of the shed and opening a plastic thin film; and discharging sewage at the bottom of the culture pond through a central sewage discharge outlet daily and simultaneously supplementing fresh water in the late stage of culture. The culture method of the penaeid shrimps in the over-winter shed can effectively utilize the idle period of the culture pond of the penaeid shrimps in winter, realize the outdoor culture of the penaeid shrimps in winter in the South, ensure the supply of fresh and live penaeid shrimps to the market in low season of the culture and improve the production benefits and the market benefits of the culture; and the culture pond of the over-winter shed for the penaeid shrimps is simple to build up, building materials can be selected according to local material sources, and the plastic thin film and a large-mesh net coat covered on the over-winter shed can ensure that the over-winter shed can realize wind resistance and no leakage of rain.

Description

technical field [0001] The invention relates to the aquaculture industry, in particular to a method for cultivating prawns in an overwintering shed and a culture pond thereof. Background technique [0002] In southern prawn farming, from mid-to-late November to mid-April of the following year, the climate is changeable and the temperature is unstable, causing the outdoor time to exceed 4 months and normal farming cannot be carried out, so the shrimp farming ponds have been idle for at least 100 days , the means of production cannot be rationally utilized, resulting in a waste of resources; in addition, because the current prawn farmers mostly adopt the traditional aquaculture structure for prawn aquaculture production, resulting in no fresh and live shrimps on the market from the end of January to May, and there is not enough shrimp in the market. Supply of fresh and live prawn products. Contents of the invention [0003] The purpose of the present invention is to provide...
