Mixed breeding method of rana nigromaculata and rice

Abstract

The invention discloses a mixed breeding method of rana nigromaculata and rice, and relates to the technical field of breeding. The method comprises the following steps: three parallel water ditches are dug in a paddy field with a length of 10 m and a width of 9 m along a length direction, distance between two adjacent water ditches is 3 m, a width of each water ditch is 1 m, a depth of each waterditch is 1.4-1.6 m, a length of each water ditch is 10 m, one rice area is arranged between two adjacent water ditches, the periphery of the paddy field is fenced by adopting a fence net, rice is planted in the rice areas, after the rice grow for 20 days, the young rana nigromaculata is stocked in the water ditches, a mixed solution of water and a tobacco stem extract liquid is sprayed to the rice every 8-10 days, and earthworms and fly maggots are thrown in the paddy field a next day after the tobacco stem extract liquid is sprayed every time. According to the mixed breeding method of the rana nigromaculata and the rice disclosed by the invention, in a mixed breeding manner of the rana nigromaculata and the rice, rice planting does not need pesticides to kill insects, the produced rice is green and pollution-free, and pests bred in the rice planting process provide a sufficient food source for breeding of the rana nigromaculata, so that the production costs are reduced.

Description

technical field [0001] The invention belongs to the technical field of breeding, and in particular relates to a mixed breeding method of black-spotted frog and rice. Background technique [0002] The black-spotted frog is a very common frog, belonging to the frog family, anura, and amphibians. The black-spotted frog has tender meat, less fat, low sugar, and high protein content. It has the effects of clearing away heat and detoxification, reducing swelling and relieving pain. The artificial breeding of black-spotted frog is not only simple in technology, but also has fast economic benefits. Therefore, the breeding of black-spotted frog is an aquatic product. Breeding hotspots. [0003] Judging from most breeding technologies in the current market, in order to increase production, natural ponds or artificially constructed ponds are generally used for high-density individual rearing. However, the intensive breeding method not only occupies land resources, but the cost of bre...

AI Technical Summary

Problems solved by technology

However, the intensive breeding method not only occupies land resources, but the cost of breeding is inevitably high, and under high-density conditions, on the one hand, it is easy to cause the spread of diseases, it is difficult to prevent and control, and the mortality rate is high; on the other hand, it cannot guarantee the quality of the water environment Compared with the quality of the product, the quality and taste of the farmed ones are very different from those of the wild ones, and the selling price is not satisfactory.
