(2) Ploughing and fertilizing
The land is defrozen in early spring, and can be ploughed, and organic fertilizer is applied at the same time, and mixed into the soil layer along with the ploughing machine.
(3) Disinfecting the water
Before loach fry are put in a suitable place for breeding, 2 times of water is fed into a circular ditch, and after the 1 st time of water feeding, dry pond cleaning is carried out according to 60 kg/mu of quicklime in the circular ditch area; and (5) after 1-2 days, feeding water for the 2 nd time, and keeping the full water level in the annular ditch. Before water is fed, the water inlet and outlet 5 uses a sleeve net with the aperture of 80 meshes to prevent wild trash fish and fish eggs from entering the annular groove 2.
(4) Rice field planting technology
The rice planting space is 9 inches in row spacing and 6 inches in plant spacing, and the mode of mechanical rice transplanting and artificial seedling supplementing is adopted.
(5) Demolish the earth dam 3
When the rice grows to reach the tillering stage, the blades of adjacent rice plants are crossed with each other to cover furrows, which is called as 'ridge sealing'. When the whole paddy field is completely ridged, the earth dam 3 can be pushed down and dismantled, and the loach fries temporarily cultured in the circular ditch 2 can freely pass in and out between the circular ditch 2 and the paddy field 1.
(6) Daily management
The field is patrolled every day, the conditions of water color change, fish activity, growth, ingestion, escape prevention facilities, enemy and the like are observed, and measures are taken in time when problems are found.
(7) Catching and harvesting
Fishing in northern areas is finished before the water temperature is reduced to 12 ℃. Firstly, draining the surface water of the field, then pulling a net in the circular ditch 2, catching most loaches, and then trapping the loaches in the circular ditch 2 for 2-3 days by using a ground cage. And finally, the water is repeatedly flushed by combining water inlet and water discharge, and concentrated catching is carried out in a manual mode.
The embodiment result shows, the utility model discloses both can satisfy the paddy field and breed loach in-process and to the bird pest prevention requirement, can not influence the paddy field farming again, convenient operation. After the paddy field is soaked and rice seedlings are transplanted, the bird prevention system can be erected, the survival rate of the loaches is improved, and the breeding risk is reduced.
