Rice-crayfish-rana nigromaculata comprehensive planting and breeding method

Abstract

The invention discloses a rice-crayfish-rana nigromaculata comprehensive planting and breeding method which comprises the following steps of selecting a proper rice field, building a heightened and widened ridge around the rice field, and installing escape-proof facilities around the ridge; from January to February, selecting submerged plants as aquatic plants to be transplanted 15-20 days before crayfish fries are put; stocking the crayfish fries in February, and catching the crayfishes in turns to come into the market in April to June when the bred crayfishes reach the commercial specification; after the crayfishes are caught, starting to plant rice from late June to early July, wherein the rice variety is selected from varieties which do not need land airing; stocking rana nigromaculata froglets which are artificially domesticated and can eat commercial artificial compound feed in the rice field 7-10 days after rice seedlings are transplanted in the rice field, and from October to November, using ground cages for catching the rana nigromaculata which is bred to the commercial specification to come into the market in turns. According to the comprehensive planting and breeding method, ditches do not need to be dug, the rice field planting area is not reduced, the advantages of continuous cropping of the rice and the crayfishes and symbiosis of the rice, the rana nigromaculata and the crayfishes are played, the time and space of the rice field are fully utilized, and the rice field utilization rate and economic benefits are improved.

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
