Embodiment Construction

[0024] Below in conjunction with specific embodiment, the method for ecological breeding of crayfish in winter idling fields of the present invention will be further described.

[0025] A kind of crayfish winter field ecological breeding method of the present invention comprises the following steps:

[0026] (1) Select suitable paddy fields

[0027] Choose a paddy field with sufficient water source and water quality in line with the national fishery water quality standard, with an area of ​​1-5 mu. The ridge is heightened and reinforced to a height of more than 50 cm. The water inlet is equipped with a filter bag made of silk screen, and the drain is installed with a fish-blocking grid. The field surface inside the ridge The vertical upward fence is a water-based anti-escape membrane that is 30cm above the field ridge; the filter bag is 2.0-2.5m long, the 25-30cm diameter sieve silk is 40 mesh, and the fish-blocking grid is a 7-mesh metal fish-blocking grid.

[0028] (2) Erza...

Abstract

The invention discloses an ecological breeding method for crayfish in a winter fallow field. The ecological breeding method comprises the following steps of selecting a suitable rice field, harvestingsecond-crop rice, reserving rice piles, stocking high-quality crayfish seeds, finely feeding feed, strengthening daily management work such as water quality regulation and the like, and harvesting atproper time. The method overcomes the defects that the unit yield level of crayfish cultured in the rice field is low and rice planting is affected, provides conditions for developing crayfish culture in the winter fallow field by fully utilizing water and soil resources of the rice field, is simple and understandable in operation, and can improve the comprehensive planting and breeding benefitsof the rice field by 50% or above.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for ecological cultivation of crayfish in a fallow field in winter. Background technique [0002] Crayfish farming in paddy fields is a practical and effective measure to improve the benefits of paddy field farming. Before the present invention, most of the crayfish farming in paddy fields was self-propagating and self-cultivating mode in Dahuangou, which not only had a low per unit yield level, but also affected rice planting, which caused doubts about the "negative effect" of crayfish paddy farming, and gave rise to the development of crayfish paddy farming. overshadowed. Contents of the invention [0003] Aiming at the disadvantages of the above technical problems, the present invention provides a method for ecological cultivation of crayfish in slack fields in winter to solve the problem that the yield per unit area is low and affects rice planting...
