Problems solved by technology

In addition, in the conventional breeding method, in the process of using aquatic plants such as Elodea and Hydrilla verticillium, the concentration of the water body is low due to the overgrowth of aquatic plants, the fertility in the water body is excessively absorbed by aquatic plants, or the water quality is corrupted due to the death of aquatic plants due to poor management. have a considerable impact on the high yield of freshwater shrimp

Embodiment Construction

[0028] The specific embodiment of the present invention is further described below:

[0029] A kind of ecological cultivation method of freshwater shrimp and water celery of the present invention is completed according to the following steps:

[0030]Take 12-15kg shrimp fry as an example:

[0031] 1) Pond conditions: Each pond uses an ordinary earthen pond of 3 to 5 mu, the slope ratio is 1:3 to 1:4, the dissolved oxygen is above 5mg / L, and the pH is 7.0 to 8.5. The vinyl double-layer dense mesh is tightly sealed to prevent the escape of shrimp seedlings and the invasion of harmful organisms. Around the pond, a ring ditch and a central ditch with a width and depth of 0.8 to 2 meters are excavated. The excavated soil is used for Reinforce the pond, the pond is 1.5 meters high, compacted and tamped firmly, no seepage and no leakage, the silt at the bottom of the pond does not exceed 10cm, the bottom is a slope structure towards the drainage, each pond is equipped with a water p...

Abstract

The invention relates to an ecological breeding method for freshwater shrimp and bengal waterdropwort herb crop rotation. The ecological breeding method comprises the following steps: (1) preparing a pond condition; (2) breeding seed bengal waterdropwort herbs; (3) stocking freshwater shrimps; (4) managing bengal waterdropwort herbs; (5) managing water quality; (6) managing feeding; (7) managing oxygenation; (8) controlling diseases; (9) harvesting the freshwater shrimps; (10) preparing a pond and fertilizing; (11) accelerating germination and rooting; (12) seeding; (13) managing a water level; (14) topdressing and weeding; (15) evenly arranging seeds and softening; (16) collecting the bengal waterdropwort herbs. Compared with the prior art, the ecological breeding method has the advantages that a pond land resource is fully utilized according to season difference of the bengal waterdropwort herbs and the freshwater shrimps, and breakthrough in a production mode is achieved; a pond ecotope is reasonably built and arranged according to the biological characteristics of the bengal waterdropwort herbs and the freshwater shrimps, and win-win is achieved; after the bengal waterdropwort herbs are bred in one season, and the pond soil quality is more favorable for the environment required by growth of the bengal waterdropwort herbs in winter no matter from the aspect of nutritional ingredients or the loose degree, so that labor cost is reduced.

Description

technical field [0001] The invention relates to the technical field of aquatic products, in particular to an ecological breeding method for freshwater shrimp and water celery in rotation. Background technique [0002] In the process of conventional freshwater shrimp farming, aquatic plants such as Elodea and Hydrilla verticillium are generally used to purify pond water quality and provide places for green shrimp to avoid habitats. In addition, in the conventional breeding method, in the process of using aquatic plants such as Elodea and Hydrilla verticillium, the concentration of the water body is low due to the overgrowth of aquatic plants, the fertility in the water body is excessively absorbed by aquatic plants, or the water quality is corrupted due to the death of aquatic plants due to poor management. It has a considerable impact on the high yield of freshwater shrimp. Contents of the invention [0003] The purpose of the present invention is to provide a kind of uti...
