Ecological method for planting rice and culturing leeches

Abstract

The invention discloses an ecological method for planting rice and culturing leeches, and belongs to the field of ecological culture of aquatic products. According to the method, rice planting basins are distributed in a culturing water body for whitmania pigra, the rice is planted in the basins, and submerged plants are planted around the culturing water body; the rice and the submerged plants continuously absorb organic matter and residual baits in the water body, inhibit the growth of the weeds and mosses in the culturing water body, and provide attachments for whitmania pigra; meanwhile, the rice shields sunlight to reduce water temperature, so that the leaches spend the high-temperature period conveniently and safely. According to the ecological method for planting the rice and culturing the leeches, by utilizing the mutualism relationships among the submerged plants, the rice and the leeches, the rice and the submerged plants are utilized to improve the growth environment of the leeches, the growth of whitmania pigra is promoted, the ecological and healthy culture of the rice and the leeches is achieved, and the economic and ecological benefits of culture are increased.

Description

technical field [0001] The invention relates to the field of ecological cultivation of special aquatic products, in particular to a method for ecological cultivation of rice and leeches. Background technique [0002] Wide-bodied golden leech is a precious Chinese medicinal material in my country, and artificial breeding has a large profit margin. At present, the artificial culture mode of wide-body leeches is mainly two kinds of culture in pond cages and cement ponds. In the breeding areas in the middle and lower reaches of the Yangtze River, leech farmers raise snails in fertilized water around April every year, and raise leech seedlings in ponds around the end of May, and start draining water to catch leeches in September of the same year. The following problems often occur in production: First, the wide-bodied golden leeches are not resistant to high temperatures, and the water level for breeding is relatively shallow. The water temperature in the breeding water body is ...

AI Technical Summary

Problems solved by technology

The following problems often occur in production: First, the wide-bodied golden leeches are not resistant to high temperatures, and the water level for breeding is relatively shallow. The water temperature in the breeding water body is high during the high-temperature period in August every year, and the wide-body golden leech grows slowly or even dies in large numbers; In order to fix the bottom of the box, the soil press box is used for net cage culture. Wild aquatic plants grow wildly in the middle and late stages of breeding. The photosynthesis of aquatic plants is strong in sunny days. Difficult to control, the wide-bodied golden leeches mainly prey on live snails in the artificial breeding water, and suck their internal organs, blood and other tissues. The muscles near the screw shells are strong, and the wide-body golden leeches cannot completely suck them, and the remaining screw meat rots and decays in the aquaculture water. Water quality, resulting in the blackening of the bottom of the water body and stench in the later stage of the wide-bodied golden leech breeding, the deterioration of the water quality,
