Problems solved by technology

In recent years, crayfish has been sought after because of its delicious meat, and the market prospect is good. However, due to the lack of artificial breeding of crayfish, people catch a large number of wild crayfish, making the natural population less and less, and the market is in short supply. Therefore, a new method is developed. The crayfish farming model is the most effective means to solve the current market vacancy by stably increasing the yield per mu of crayfish on the premise of being beneficial to the environment

Embodiment 1

[0020] A rice field ecological crayfish cultivation method, comprising the following steps:

[0021] (1) Site selection: After the rice is harvested, select paddy field soil with sufficient water source, convenient drainage and irrigation, fertile soil and strong water retention;

[0022] (2) Construction: Dig "ten" and "well"-shaped ditches in the middle of the field. The width of the ditches is 1.0 meters, the depth is 0.7 meters, and the interval between each ditch is 5 meters. After the horizontal and vertical ditches are formed Obtain a crayfish breeding site;

[0023] (3) Reinforcement: the base of the ridge is widened to 1.2 meters, the ridge is compacted, and the slope ratio is 1:2;

[0024] (4) Anti-escape: the field ridges shall be heightened, and smooth baffles shall be installed with a height of 0.8 meters, and anti-escape nets shall be installed at both inlet and outlet outlets;

[0025] (5) Equipment placement: Aerators and water pumps are placed in the breedin...

Embodiment 2

[0034] A rice field ecological crayfish cultivation method, comprising the following steps:

[0035] (1) Site selection: After the rice is harvested, select paddy field soil with sufficient water source, convenient drainage and irrigation, fertile soil and strong water retention;

[0036] (2) Construction: Dig "ten" and "well"-shaped ditches in the middle of the field. The width of the ditches is 1.2 meters, the depth is 0.8 meters, and the interval between each ditch is 7 meters. After the horizontal and vertical ditches are formed Obtain a crayfish breeding site;

[0037] (3) Reinforcement: the base of the ridge is widened to 1.5 meters, the ridge is compacted, and the slope ratio is 1:3;

[0038] (4) Anti-escape: the field ridge shall be heightened, and a smooth baffle shall be installed. The height of the baffle shall be 1.5 meters, and an anti-escape net shall be installed at both the inlet and outlet outlets;

Abstract

The invention discloses a paddy field ecological crayfish cultivation method, which includes the following steps: (1) site selection; (2) construction; (3) reinforcement; (4) escape prevention; (5) equipment placement; (6) disinfection; (7) fertilization; (8) rice field ecosystem establishment; (9) shrimp fry stocking; (10) feed feeding; (11) field management; and (12) timely catching for reduction of crayfish cultivation density. The method has the advantages that the method is simple and low in cost; by adopting a paddy field ecological cultivation method, crayfish cultivation and rice cultivation can be organically combined, so that the crayfish cultivation and rice cultivation are mutually beneficial and symbiotic, the productivity of farmland is fully brought into play, and the economic benefits of farmland management are improved; and the method makes full use of the cultivation space, feeding and field management methods are reasonable, so that the yield of crayfish is effectively improved.

Description

technical field [0001] The invention relates to the technical field of crayfish cultivation, in particular to a paddy field ecological crayfish cultivation method. Background technique [0002] Freshwater lobster, commonly known as crayfish, belongs to the class Arthropoda Crustacea and Decapod Lobster family. It has a thick head and chest, a hard shell, and delicious meat. It is a nutritional and nourishing food with low fat, low cholesterol and high protein. Freshwater lobster not only has a large body and plump meat, but also has the characteristics of short growth cycle, high yield and strong adaptability to miscellaneous food. In recent years, crayfish has been sought after because of its delicious meat, and the market prospect is good. However, due to the lack of artificial breeding of crayfish, people catch a large number of wild crayfish, making their natural population less and less, and the market is in short supply. Therefore, a new method is developed. The advan...
