Ecological breeding method for polyculture of Thailand tiger frogs in rice field

Abstract

The invention relates to the technical field of aquaculture, and provides an ecological breeding method for polyculture of Thailand tiger frogs in a rice field. An ecological three-dimensional breeding mode of ratoon rice, tiger frogs, cipangopaludina chinensis, and loaches is established, and various biological characteristics and material circulation principles are utilized to form a symbiotic and mutual benefit relationship. The rice field provides a superexcellent inhabiting environment and rich natural bait organisms for the tiger frogs, agricultural cultivated land is not occupied, and the bred tiger frogs are compact in meat quality and delicious in meat taste; thailand tiger frogs can prey insects and have biological prevention and control effects on rice diseases and insect pests, and excrement of the tiger frogs can improve fertility of the rice field and improve soil activity, so that chemical fertilizers and pesticides are not needed in the rice field in the planting process. The cipangopaludina chinensis and the loaches are cultured in a mixed mode and eat dead frogs, and food safety is guaranteed. Through a paddy-upland rotation deep ploughing planting mode, the soil ploughing quality is improved, the soil activity is improved, plant diseases and insect pests are reduced, and vegetables are sown in idle fields, so that the utilization rate of the fields is increased, and greater economic benefits are created.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to an ecological breeding method for polyculture of Thai tiger frogs in paddy fields. Background technique [0002] Tiger frogs, commonly known as "frogs" and "water chickens", are currently bred in captivity mainly by Thai tiger frogs, and there are also some native tiger frogs. The two belong to two species. Although they are similar in appearance, they are different. Large-scale artificial breeding of tiger frogs in China began in 1995. Since the first batch of tiger frogs were imported from Thailand to Hainan by overseas Chinese from Hainan, they have always been called Thai tiger frogs. After that, the breeding area gradually expanded to Guangdong, Guangxi, Fujian, Jiangxi, Hunan, Zhejiang, Jiangsu and other places. Since 1995, Hainan Province has been the most important breeding area in the country. In 2000, the tiger frog breeding scale in Hainan Province reached its pea...

AI Technical Summary

Problems solved by technology

Due to the high density of breeding and the large amount of feeding, the tail water of farming does not meet the discharge standards. If it is discharged directly, it will easily pollute the environment; if it is treated to meet the water environment standards, it will greatly increase the cost of farming.

(2) Occupation of cultivated land

Intensive farming methods take up a lot of farmland

(3) Food safety issues

This invention adopts a low-density breeding method. Although tiger frogs and soft-shelled turtles can basically not get sick, the yield per mu of tiger frogs is too low, only reaching 270kg / mu, and it is difficult to realize the high-efficiency desire of artificially breeding tiger frogs
