Background
With the deterioration of the planting environment of rice, the occurrence of diseases, insect pests and weeds is getting more and more serious, and in the traditional production, chemical fertilizers and pesticides become main means for ensuring the yield of rice. The environment pollution, low output value and slow efficiency improvement are caused. The cultured river crabs in ponds, lakes and the like are covered with caps which pollute water and destroy ecological environment. The development of novel rice planting and river crab culture technologies is imminent.
In the prior art, the crabs are directly bred in the rice field, but the crabs move in the rice field, so that the action is inconvenient, and the action of the crabs can damage the root system of the rice, thereby reducing the yield of the rice. And is inconvenient for catching crabs after the crabs are bred and mature.
Disclosure of Invention
The invention provides a method for breeding rice crabs by circulating water, which aims to solve the technical problem that the rice crabs influence each other in the prior art.
The technical scheme adopted by the invention for solving the technical problem is that,
a rice and crab recirculating aquaculture method comprises the following steps:
selecting a breeding rice field:
the rice field can be rectangular, square, round, irregular and the like.
Digging a ditch along half of the periphery of the rice field, wherein the depth of the ditch is 1-1.2 m, and the width of the ditch is 0.2-0.5 m. The crab cannot be caught because the ditch is too deep, and the crab can climb out because the ditch is too shallow. Too narrow a ditch is not beneficial to the movement of crabs, and too wide a ditch can influence the planting of rice.
And a barrier is arranged between the ditch and the paddy field so as to be beneficial to filling water in the paddy field. But the barriers between the ditches and the rice field are more than 0.3 m (preferably 0.4-0.6 m) lower than the outermost barriers of the rice field, so that the water level is deepened when the rice field is not sown, and the breeding area and the activity space of the crabs are increased.
The other half of the periphery of the paddy field without ditching is provided with a pipeline and a water pump so as to be beneficial to water exchange and circulation between paddy fields and ditches.
Secondly, crab larvae are released: crab seedlings are placed in 3 months, and the crab seedlings are placed according to the total area of the ditches and the rice field and the proportion of 0.2-0.3 kg of crab seedlings in each mu of rice field;
at the moment, no rice is planted in the rice field, water can be added to a barrier between a ditch and a paddy field, crabs can move in the ditch and the paddy field in a large area, and the water quality of the paddy field cannot be deteriorated due to large breeding area, low density of the crabs and less fed fodder, so that the water quality can be kept good without circulating water, and the water does not need to be changed.
(III) water circulation: transplanting rice in the 6 th month, putting the water in the ditch below the field surface of the rice field before transplanting rice, and driving all crabs into the ditch; after rice is transplanted, as the temperature begins to rise, crabs grow and concentrate in the ditch, and the water quality in the ditch begins to slowly deteriorate; and (3) starting a water pump, pumping the fertilizer water in the ditch into the rice field, absorbing nutrition (generally about 5-10 days) by the rice, and then refluxing the water in the rice field into the ditch to form water circulation.
(IV) harvesting rice and catching crabs.
According to the method for culturing the rice and the crabs by circulating water, the excrement of the crabs can fertilize the field, and the rich water can promote the growth of rice; after the rice absorbs the nutrient substances in the fertilizer water, the water is purified, the water can be recycled, the waste of the water and the fertilizer is avoided, the additional application of chemical fertilizer is basically not needed, the environment is not polluted, the rice and the crabs are mutually beneficial, and a virtuous cycle is formed. The crabs are arranged in the ditches, and the independent moving space can not damage the root system of the rice, and the yield of the rice and the crabs can be improved.
In addition to the objects, features and advantages described above, other objects, features and advantages of the present invention are also provided. The present invention will be described in further detail below with reference to the drawings.

Detailed Description
The embodiments of the invention will be described in detail below with reference to the accompanying drawings, but the invention can be embodied in many different forms, which are defined and covered by the following description.
FIG. 1 is a schematic view showing the structure of a paddy field and a ditch in accordance with a preferred embodiment 1 of the present invention.
Example 1
As shown in fig. 1, the crab recirculating aquaculture method of the embodiment includes the following steps:
selecting a breeding rice field:
the rice field is rectangular.
The furrows were dug along half of the outer periphery of the rice field with a depth of 1 m and a width of 0.3 m. The crab cannot be caught because the ditch is too deep, and the crab can climb out because the ditch is too shallow. Too narrow a ditch is not beneficial to the movement of crabs, and too wide a ditch can influence the planting of rice.
And a barrier is arranged between the ditch and the paddy field so as to be beneficial to filling water in the paddy field. But the barrier between the ditch and the paddy field is 0.4 m lower than the barrier at the outermost periphery of the paddy field, so that the water level is deepened when the paddy field is not sown, and the breeding area and the activity space of the crabs are increased.
The other half of the periphery of the paddy field without ditching is provided with a pipeline and a water pump so as to be beneficial to water exchange and circulation between paddy fields and ditches.
Secondly, crab larvae are released: crab seedlings are put in 3 months, and the crab seedlings are put in a proportion of 0.3 kg per mu of rice field according to the total area of the ditch and the rice field;
at the moment, no rice is planted in the rice field, water can be added to a barrier between a ditch and a paddy field, crabs can move in the ditch and the paddy field in a large area, and the water quality of the paddy field cannot be deteriorated due to large breeding area, low density of the crabs and less fed fodder, so that the water quality can be kept good without circulating water, and the water does not need to be changed.
(III) water circulation: transplanting rice in the 6 th month, putting the water in the ditch below the field surface of the rice field before transplanting rice, and driving all crabs into the ditch; after rice is transplanted, as the temperature begins to rise, crabs grow and concentrate in the ditch, and the water quality in the ditch begins to slowly deteriorate; and (3) starting a water pump, pumping the fertilizer water in the ditch into the rice field, absorbing nutrition by the rice (generally 5-10 days, and after the water is clear by visual inspection), and then refluxing the water in the rice field into the ditch to form water circulation.
(IV) harvesting rice and catching crabs.
According to the method for culturing the rice and the crabs by circulating water, the excrement of the crabs can fertilize the field, and the rich water can promote the growth of rice; after the rice absorbs the nutrient substances in the fertilizer water, the water is purified, the water can be recycled, the waste of the water and the fertilizer is avoided, the additional application of chemical fertilizer is basically not needed, the environment is not polluted, the rice and the crabs are mutually beneficial, and a virtuous cycle is formed. The crabs are arranged in the ditches, and the independent moving space can not damage the root system of the rice, and the yield of the rice and the crabs can be improved. The yield of the rice is improved by 10 percent compared with that of the rice applying chemical fertilizer, and the yield of the crabs is improved by 20 percent compared with that of the crabs raised alone.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
