Embodiment 1

[0028] Example 1 Crab Cultivation Paddy Field

[0029] Please refer to attached figure 1 , with figure 1 It is a model diagram of paddy field breeding. The intensive crab paddy farming model is composed of several crab breeding paddy fields. The crab breeding paddy field includes a water channel 1, a water inlet pipe 2, a ridge 3, a rice planting area 4, and aquatic plants. Planting area 5 and rice field crab ditch 6 and other components. The rice planting area 4 is divided into the rice planting area around the field and several inner rice planting areas, the rice planting area around the field is in a rectangular ring shape, and the rice field crab ditch 6 is set on the inner side of the inner ring, and the rice field crab ditch 6 and the inner rice planting area The blank space between the districts is aquatic plant planting area 5, where aquatic plants are planted. The outer periphery of the rice planting area 4 is a field ridge 3, a water channel 1 is arranged on one...

Embodiment 2

[0032] Embodiment 2 Anti-theft, anti-escape and anti-bird measures

[0033] In the described paddy field for buckling crab breeding, the standardized culture anti-escape and anti-theft measures of “first-level anti-theft, plastic steel fence; Nylon nets are set, and plastic plates are set on the outer periphery of the ridge 3, which are used to buckle crabs and prevent escape. The periphery of the ridge 3 of the described crab breeding paddy field is also provided with a plastic-steel fence for preventing theft of crabs. At the same time, it is also possible to plant loofah, wax gourd, pumpkin and other creeping climbing herbs on the ridge near the plastic steel fence.

[0034] In addition, please refer to the attached figure 2 , with figure 2 It is a schematic diagram of the structure of the bird-proof fence. The bird-proof fence is to set cement piles at intervals around the field ridge, lead wires are drawn between the cement piles, and then white nylon wires are dra...

Embodiment 3

[0036] Example 3 Microporous oxygenation technology

[0037] In the intensive crab paddy breeding mode of the present invention, microporous aeration pipes can also be laid at the bottom of the paddy field, and the microporous aeration technology can be used to increase the dissolved oxygen content in the pond and the weight of the crabs, and the water quality can be improved within a certain range. Improve the utilization rate of feed, accelerate the growth of seedlings, and increase the yield and economic benefits of crabs.

[0038] The microporous aeration technology uses a Roots blower to press the air into the air pipeline, then sends it into the microporous tube, and disperses it into the water in the form of microbubbles. The microbubbles float upward from the bottom of the pool to promote the full dissolution of oxygen into the water. , It can also cause the rotation and up-and-down flow of the water flow, so that the oxygen-rich water in the upper layer of the pond ...

Abstract

The invention relates to an intensive juvenile crab paddy field aquaculture mode, which comprises juvenile crab aquaculture paddy fields which are connected together. Each juvenile crab aquaculture paddy field comprises a canal, a water inlet pipe, a ridge, rice planting area, a waterweed planting area and paddy field crab ditches. The rice planting area is divided into a ring field rice planting area and inner rice planting areas. The ring rice planting area is of the shape of a rectangular ring. The paddy field crab ditches are arranged on the internal side of the inner ring of the ring rice planting area. The waterweed planting area is arranged between the paddy field crab ditches and the inner rice planting areas and is used for planting waterweeds. The ridge is arranged on the periphery of the rice planting area. The canal is arranged on one side of the ridge. The water inlet pipe is arranged between the canal and the paddy field crab ditches. The intensive juvenile crab paddy field aquaculture mode has the advantages that the aquaculture mode promotes the standard aquaculture of juvenile crabs, the time and the labor for feeding feed and the like are saved, the labor cost is saved, the uniform intensive aquaculture production is facilitated, the crabs can be effectively prevented from being stolen, escaping and being eaten by birds, and the economic benefits are obviously improved by improving values of crops, rice and juvenile crabs.

Description

technical field [0001] The invention relates to the field of aquaculture ecological cultivation, in particular, it is an ecological compound intensive paddy field culture mode for crabs which is specially used for culturing crabs and which can solve many problems in general paddy field cultivation of crabs. Background technique [0002] River crabs, also known as hairy crabs, are native to my country and are called Chinese velvet crabs in zoology. They are mainly distributed in rivers and lakes along the coasts of various sea areas in eastern China and leading to the sea. The growth process of crabs is to breed crabs by young crabs, and then put the crabs into crab ponds or lakes for further breeding into finished crabs sold on the market. [0003] Raising crabs in rice fields combines rice planting and river crab farming based on the principle of symbiosis between rice and river crabs. River crabs move and forage in rice fields, which not only play the role of cultivating,...
