Embodiment 1

[0017] A high-yield method for culturing crayfish in paddy fields, comprising the following steps:

[0018] ①: Choose paddy fields with sufficient water sources, convenient irrigation and fertile soil, and ensure that the surrounding paddy fields have a good ecological environment and no pollution sources;

[0019] ②: Dig a rice ditch in the paddy field in ①, and the size of the rice ditch is 3.5 meters wide and 1 meter deep. When the paddy field needs to be drained and transplanted, the unsold juvenile shrimp will have a spacious and sufficient growth The water area effectively guarantees its growth environment, and an isolation net is set at both ends of the rice ditch, and the isolation net needs to penetrate 40cm into the soil to prevent crayfish from escaping;

[0020] ③: After the stocking is completed, the lobster feed needs to be spread evenly in the paddy field quickly, and the weight of the lobster feed is 60kg / mu, and then the lobster feed needs to be put into the p...

Embodiment 2

[0025] A high-yield method for culturing crayfish in paddy fields, comprising the following steps:

[0026] ①: Choose paddy fields with sufficient water sources, convenient irrigation and fertile soil, and ensure that the surrounding paddy fields have a good ecological environment and no pollution sources;

[0027] ②: Dig a rice ditch in the paddy field in ①, and the size of the rice ditch is 4.5 meters wide and 1.4 meters deep. When the paddy field needs to be drained and transplanted, the unsold juvenile shrimp will have a spacious and sufficient growth The water area effectively guarantees its growth environment, and an isolation net is set at both ends of the rice ditch, and the isolation net needs to penetrate 45cm into the soil to prevent crayfish from escaping;

[0028] ③: After the stocking is completed, the lobster feed needs to be spread evenly in the paddy field quickly, and the weight of the lobster feed is 70kg / mu, and then the lobster feed needs to be put into th...

Embodiment 3

[0033] A high-yield method for culturing crayfish in paddy fields, comprising the following steps:

[0034] ①: Choose paddy fields with sufficient water sources, convenient irrigation and fertile soil, and ensure that the surrounding paddy fields have a good ecological environment and no pollution sources;

[0035] ②: Dig a rice ditch in the paddy field in ①, and the size of the rice ditch is 5.5 meters wide and 1.8 meters deep. When the paddy field needs to be drained and transplanted, the unsold juvenile shrimp will have a spacious and sufficient growth The water area effectively guarantees its growth environment, and an isolation net is set at both ends of the rice ditch, and the isolation net needs to penetrate 55cm into the soil to prevent crayfish from escaping;

[0036] ③: After the stocking is completed, the lobster feed needs to be spread evenly in the paddy field quickly, and the weight of the lobster feed is 80kg / mu, and then the lobster feed needs to be put into th...

Abstract

The invention discloses a high-yield method for farming crayfish in a rice field, which comprises the steps of digging rice ditches in a rice field, arranging isolation nets at two ends of the rice ditches, enabling the isolation nets to be 40-55 cm deep in the soil, after the rice field treatment is completed, adding weed and feed again into the rice ditches, releasing young crayfishes into the rice field, with the young crayfishes placed at intervals, after releasing is completed, spreading crayfish feed quickly and uniformly into the rice field, adding the crayfish feed timely into the ricefield every other day, changing water of the rice field every five days, with water depth of the rice field not lower than 7 cm, and catching mature crayfishes 2-3 months after the young crayfishes are released. The method herein promotes the organic combination of the planting industry and the farming industry, so that the rice and crayfish form a benign circulation ecological symbiotic chain, resources are effectively saved, the utilization rate of the resources is increased, and the yield of crayfish is greatly increased.

Description

technical field [0001] The invention relates to the technical field of lobster cultivation, in particular to a method for high-yield cultivation of crayfish in paddy fields. Background technique [0002] The scientific name of freshwater crayfish is Procambarus clarkii. The shrimp originated in the United States and was introduced to Nanjing from Japan in the 1930s. After more than 80 years of reproduction and expansion, my country has become the country with the fastest development of freshwater crayfish farming. my country's crayfish farming started in the middle of the last century, mainly concentrated in Hubei, Jiangsu, Anhui and other provinces in the middle and lower reaches of the Yangtze River. In the early stage of crayfish farming, various farming models such as rice fields, ponds, rivers and grass lakes were adopted. Practice has proved that rice fields are the best growth habitats for freshwater crayfish. In the middle and lower reaches of the Yangtze River in ...
