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 ...
