Embodiment 1

[0029] A method for multi-cropping polyculture in ponds to improve the yield of Penaeus japonicus, comprising:

[0030] (1) Pond selection and treatment: select a pond with an area of ​​40 mu of sand and mud bottom, and carry out dredging from late March to early April. After several days of exposure to the sun, sprinkle quicklime on the bottom of the pond, and the amount of quicklime is 1125kg / hm 2 , and then inject 1m of seawater into the pool, and then sprinkle a certain concentration of chlorine dioxide into the water for disinfection. After drying for half a month, sprinkle amino acid fertilizer (manufacturer: Jiangsu Haorun Biological Technology Co., Ltd., model: Super Algae Run II) in the water, the amount of amino acid fertilizer is 1ppm, and fertilize the water.

[0031] (2) Selection and delivery of shrimp seedlings: select healthy and lively shrimp seedlings with a body length of 0.5-0.8cm; from the end of April to the end of July, release them in 4 times, each time...

Embodiment 2

[0041] A method for multi-cropping polyculture in ponds to improve the yield of Penaeus japonicus, comprising:

[0042] (1) Pond selection and treatment: select a pond with an area of ​​40 mu of sand and mud bottom, and carry out dredging from late March to early April. After several days of exposure to the sun, sprinkle quicklime on the bottom of the pond, and the amount of quicklime is 1500kg / hm 2 , and then inject 1m of seawater into the pool, and then sprinkle a certain concentration of chlorine dioxide into the water for disinfection. After drying for half a month, sprinkle amino acid fertilizer (manufacturer: Jiangsu Haorun Biological Technology Co., Ltd., model: Super Algae Run II) in the water, the amount of amino acid fertilizer is 1ppm, and fertilize the water.

[0043] (2) Selection and distribution of shrimp seedlings: select healthy and lively shrimp seedlings with a body length of 0.5-0.8 cm; from the end of April to the end of July, they are distributed in 4 tim...

Embodiment 3

[0053] A method for multi-cropping polyculture in ponds to improve the yield of Penaeus japonicus, comprising:

[0054] (1) Pond selection and treatment: select a pond with an area of ​​80 mu of sand and mud bottom, and carry out dredging from late March to early April. After several days of exposure to the sun, sprinkle quicklime on the bottom of the pond, and the amount of quicklime is 1350kg / hm 2 , and then inject 0.9m of seawater into the pool, and then sprinkle a certain concentration of chlorine dioxide into the water for disinfection. ), after drying for half a month, sprinkle amino acid fertilizer (manufacturer: Jiangsu Haorun Biotechnology Co., Ltd., model: Super Algae Run II) in the water, the amount of amino acid fertilizer is 0.9ppm, and fertilize the water.

[0055] (2) Selection and delivery of shrimp seedlings: select healthy and lively shrimp seedlings with a body length of 0.5-0.8cm; from the end of April to the end of July, release them in 4 times, each time ...

Abstract

The invention discloses a multi-crop polyculture method in ponds for increasing the yield of Penaeus japonicus, and belongs to the technical field of aquaculture. The above method includes: step 1: pond selection and treatment; step 2: shrimp seed selection and release; step 3: crab seed selection; step 4: daily water quality management; step 5: feeding management; step 6: timely fishing. In summary, this application discloses the multi-crop polyculture model of Penaeus trituberculatus and Portunus trituberculatus. During the polyculture of Penaeus trituberculatus and Portunus trituberculatus, Portunus trituberculatus will eat the carcasses of Penaeus trituberculatus, which can effectively prevent shrimp diseases further dissemination; the breeding steps are scientific and reasonable, which can effectively increase the yield and survival rate of Penaeus japonicus, and the two together increase economic benefits.

Description

technical field [0001] The invention relates to polyculture technology of Penaeus japonicus in ponds, and specifically discloses a multi-crop polyculture method in ponds capable of increasing the yield of Penaeus japonicus. Background technique [0002] Japanese prawns (Marsupenaeus japonicas), formerly known as Japanese prawns, belong to the order Decapod, Penaeidae, and the genus Penaeus. One of the species of prawn farming, Penaeus japonicus grows rapidly, is resistant to dew, bright in color and has high economic value. It is popular in the aquatic product market and farmers. It is cultivated in various provinces and cities from the south to the north of my country, and has formed a certain scale. . At present, Penaeus japonicus is mainly cultured in ponds, and the output is low, which is difficult to meet the current market demand. A new pond culture model is needed to change the status quo. [0003] Portunus trituberculatus (Portunus trituberculatus), commonly known as...
