Description
Technical Field
The invention relates to the technical field of ecological aquaculture and the technical field of rice ecological planting, in particular to a one-ditch two-plant three-plant circulating clean water crab and rice symbiotic planting and breeding method.
Background
With the continuous innovation of modern agricultural technology, agricultural planting and aquaculture are combined and reasonably matched, and the shallow water environment of a rice field is utilized to plant rice and simultaneously culture aquatic products. The aquatic products can eat pests and weeds in the rice field, and the excrement of the aquatic products can also provide nutrients for rice, so that a green cultivation and planting mode is formed.
Crabs are class-A reptiles, also called hairy crabs and hairy crabs, and are delicious food which is popular in China for a long time. The crab feet are used for taking food and resisting enemies, and the inner and outer edges of the palm are densely provided with villi, so the crab is named. The hairy crab is a favorite food for people, and has delicious taste and high nutritive value.
Crabs are taken as a typical example of aquatic products, have stronger vitality, delicious taste, rich nutrition and higher economic value, so that the symbiotic ecological breeding mode of rice and crabs is formed, the sustainable development of breeding is facilitated, high-quality and safe food and aquatic products are produced, and the income of farmers can be increased. The invention patent application CN104145759A discloses a method for symbiotic cultivation of rice and crabs, CN112219660A discloses a method for ecologically cultivating rice and crabs, which utilizes rice to provide food for river crabs for inhabitation, sunshade and cooling places, aquatic organisms and the like, excrement and sinking feed discharged by the river crabs provide high-quality fertilizer for the rice, so that the using amount of the fertilizer is reduced, part of weeds eaten by the river crabs are reduced, the application of herbicide is reduced, the soil is activated by the movement of the river crabs, the soil structure is improved, and the fertilizer is activated and is easy to absorb to promote the growth of the rice; the invention patent 201710127156.X discloses a method for preventing and controlling farmland non-point source pollution by using rice and crab co-operation, which integrates the respective characteristics of the planting industry and the breeding industry, has a certain control effect on the nitrogen content of a water body, but has a limited purification effect of a single plant, and does not realize the recycling of the water body.
However, all the related patents or prior arts disclosed have the following problems:

Therefore, how to coordinate the rice planting area and the hairy crab culture water area is one of the difficulties in rice and crab symbiosis, and the rice yield and the culture benefit are ensured.
(2) The hairy crabs are generally bred in June, ripened before and after October and fished, and the field cannot be sunned in the middle. The rice variety must be matched with the growth period of the crabs, and can not fall down after long-term soaking in water and stopping soaking in water before harvesting, and the determination of the rice variety is one of the difficulties to be solved for the symbiosis of the rice and the crabs.
(3) In the hairy crab cultivation process, the cultivation water body needs to be exchanged regularly to ensure that the water quality and the oxygen content in the water body are kept in the optimal state in the cultivation process, and a large amount of water body is required in the processes. Meanwhile, due to global climate change, extreme climate frequently occurs, so that the rainfall season and the annual interval change greatly, and the popularization of water surface culture or rice field culture is not facilitated. On the other hand, crab tail water is not matched with the requirement of rice. Therefore, how to realize the efficient reuse and zero pollution of tail water in the hairy crab cultivation process is a technical problem which needs to be solved for developing green ecological paddy field cultivation.
