A method for comprehensive cultivation of rice-crayfish-black-spotted frog

Abstract

The invention discloses a rice-crayfish-black-spotted frog comprehensive planting method: select a suitable paddy field, build heightened and widened field ridges around the paddy fields, and install anti-escape facilities around the field ridges; 15-20 days before stocking shrimp seedlings, select submerged water plants as aquatic plants for transplanting; stock crayfish seedlings in February, and in April-June, cultivate crayfish until they reach commercial specifications; after harvesting crayfish, From the end of June to the beginning of July, rice is planted, and the rice varieties are selected from varieties that do not need to be sun-dried; 7-10 days after the rice field is transplanted, the black-spotted frog young frogs that have been artificially domesticated and can eat commercial artificial compound feed are released in the rice field. ‑November, the black-spotted frogs that have been bred to commercial specifications are caught and marketed by ground cages. The comprehensive planting and breeding method of the present invention does not need to dig ditches, does not reduce the planting area of ​​the paddy field, takes advantage of the continuous cropping of rice and crayfish and the symbiosis of rice, black-spotted frog, and crayfish, fully utilizes the time and space of the paddy field, and improves the utilization rate of the paddy field and economic benefits.

Description

technical field [0001] The invention relates to a method for comprehensive cultivation of rice-crayfish-black-spotted frog. Background technique [0002] Food is the most important thing for the people. Food is not only an important strategic material related to the national economy, the people's livelihood and national security, but also the most basic means of production for the people. Rice is an annual grass plant that is eaten by nearly half of the world's population, including almost all of East and Southeast Asia. Rice is widely planted in my country, and a certain amount of chemical fertilizers and pesticides need to be applied during the planting process. In order to improve the economic benefits per unit area of ​​cultivated land, under the premise of ensuring stable rice production, appropriate aquaculture is carried out by utilizing paddy field wetland resources, and the model of rice fish farming has been gradually formed in my country and has been widely promo...

Problems solved by technology

[0004] Although the existing planting and breeding models can improve the breeding efficiency, there are still deficiencies. For example, these planting and breeding models all need to dig ditches. , aquatic animals can survive in the ditch

In addition, the current continuous cropping and symbiotic breeding mode still has shortcomings, such as continuous cropping of rice, crayfish, soft-shelled turtles and rice, crayfish, and rice field eels, and carnivorous soft-shelled turtles and rice field eels in the symbiotic breeding mode will prey on crayfish seedlings, That is, different aquaculture species cannot "peacefully coexist" and affect the efficiency of aquaculture
