Abstract
The invention discloses an ecological shrimp and crab polyculture method. The method comprises the following steps of 1 culture pond selecting; 2 plant planting, wherein lotus roots are planted at the bottom of a culture pond in February to March, and water caltrops are planted on the water surface of the culture pond; 3 mulberry tree transplanting, wherein mulberry trees with the diameter of 8-10 cm are transplanted at the edge of the culture pond in March, and cicadae are stocked on the mulberry trees; 4 young shrimp putting, wherein dynamic young river shrimps with the uniform body color are put into the culture pond, 2000-3000 young shrimps are put per mu, and timed feeding is performed; 5 young crab putting, wherein young crabs are put into the culture pond in late April, 1900-2000 young crabs are put per mu, and timed feeding is performed. In this way, the lotus roots and the water caltrops can purify the water quality and decrease the morbidity probability of the crabs; the mulberry trees, the lotus roots and the water caltrops also can regulate the illumination intensity of the water surface of the culture pond, the activity amount of the crabs is decreased, and therefore the crab yield is increased; the crabs can eat part of the river shrimps to supplement protein, and therefore the crab quality is improved.
Description
Technical field
The present invention relates to a kind of ecological Mixed cultivation of prawn and crab method.
Background technology
Crab is a kind of fishery products, and it contains abundant protein and trace element, and health has good tonic effect, and it also has the pharmaceutical use of tuberculosis, and the rehabilitation of tuberculosis is had greatly help. Owing to its meat is fine and smooth delicious, become the course that people like very much. But, in existing crab cultivation process, culture pond only cultivates crab, biological single, it is easy to causing water quality to become bad, the probability making crab sick increases, and reduces crab output. It is therefore desirable to provide a kind of new cultural method to solve the problem.
Summary of the invention
It is an object of the invention to provide a kind of ecological Mixed cultivation of prawn and crab method that can improve crab output.
In order to realize above-mentioned purpose, the technical solution adopted in the present invention is as follows:
A kind of ecological Mixed cultivation of prawn and crab method, comprises the following steps:
A) select culture pond: select have abundant water resources, enter draining easily pond as culture pond;
B) plant is planted: lotus rhizome on planting bottom culture pond in 2-3 month, at culture pond water surface planting water caltrop;
C) mulberry tree is transplanted: in March, the mulberry tree that diameter is 8-10cm is transplanted to the edge of culture pond, mulberry tree is put in a suitable place to breed cicada worm;
D) throw in shrimp seedling: at the beginning of 4 months by body colour evenly, have the river prawn shrimp seedling of vigor to drop in culture pond, only throw in 2000-3000, circadian feeding for every mu;
E) juvenile crab is thrown in: in juvenile crab input culture pond physique is healthy and strong, anosis without wound by the end of April, only throw in 1900-2000, circadian feeding for every mu.
Preferably, the edge of described culture pond is provided with and anti-escapes net for what prevent that shrimp and crab from runing away.
Preferably, described anti-escaping to be evenly distributed with mesh on the net, the maximum width of described mesh is greater than 1cm and is less than 2cm.
Preferably, the average intensity of illumination of the described culture pond water surface is less than 3900LUX.
Preferably, the cultivated area of described lotus rhizome accounts for the 50%-60% of the described culture pond total area, and the cultivated area of described water caltrop accounts for the 20%-30% of the described culture pond total area.
Compared with prior art, the useful effect of the ecological Mixed cultivation of prawn and crab method of the present invention is: described lotus rhizome and water caltrop can purify water, and reduce crab incidence rate;Described mulberry tree, lotus rhizome and water caltrop can also regulate the intensity of illumination of the culture pond water surface, reduce the activity of crab, thus improve crab output; Described crab can search for food part river prawn, supplements protein, promotes the quality of crab.
Embodiment
Below in conjunction with specific embodiment, the present invention is described further.
The present invention provides a kind of ecological Mixed cultivation of prawn and crab method, comprises the following steps:
A kind of ecological Mixed cultivation of prawn and crab method, comprises the following steps:
A) select culture pond: select have abundant water resources, enter draining easily pond as culture pond;
B) plant is planted: lotus rhizome on planting bottom culture pond in 2-3 month, at culture pond water surface planting water caltrop;
C) mulberry tree is transplanted: in March, the mulberry tree that diameter is 8-10cm is transplanted to the edge of culture pond, mulberry tree is put in a suitable place to breed cicada worm;
D) throw in shrimp seedling: at the beginning of 4 months by body colour evenly, have the river prawn shrimp seedling of vigor to drop in culture pond, only throw in 2000-3000, circadian feeding for every mu;
E) juvenile crab is thrown in: in juvenile crab input culture pond physique is healthy and strong, anosis without wound by the end of April, only throw in 1900-2000, circadian feeding for every mu.
In the present invention, the edge of described culture pond is provided with anti-escapes net for what prevent that shrimp and crab from runing away, described anti-escaping to be evenly distributed with mesh on the net, the maximum width of described mesh is greater than 1cm and is less than 2cm, arranges anti-escaping and prevents crab from escaping when net can change water or unmanned nurse in pond.
In addition, the cultivated area of described lotus rhizome accounts for the 50%-60% of the described culture pond total area, and the cultivated area of described water caltrop accounts for the 20%-30% of the described culture pond total area.
Described lotus rhizome and water caltrop can purify water, and reduce crab incidence rate; Lotus planting and water caltrop can also improve the utilization ratio of culture pond, increase the output of agricultural-food, and the ight soil of described cicada worm is fallen in culture pond, it is possible to for lotus rhizome and water caltrop provide natural organic fertilizer material.
Simultaneously, lotus rhizome, water caltrop and mulberry tree can regulate the intensity of illumination of the culture pond water surface, make the average intensity of illumination of the described culture pond water surface be less than 3900LUX, and appropriate reduction illumination can simulate the natural living environment of crab, the activity being convenient to reduce crab, thus improve crab output. Described river prawn as the protein food of crab, can promote crab quality.
Schematically the present invention and enforcement mode thereof being described above, this description does not have restricted, and actual enforcement is not limited thereto. So, if the those of ordinary skill of this area enlightens by it, when not departing from the invention objective, design the structure mode similar to this technical scheme and embodiment without creativeness, protection scope of the present invention all should be belonged to.
