Description

A kind of leech breeding box

technical field

The utility model relates to the technical field of leech cultivation, in particular to a leech cultivation box.

Background technique

Leech, commonly known as leech, grows and reproduces in inland freshwater waters. It is a traditional special medicinal aquatic animal in my country. Its dried products are used as medicine in traditional Chinese medicine after brewing. It is mainly used to treat bruises, stroke, amenorrhea, bleeding and postpartum Blood dizzy and other symptoms. It is recorded in the Pharmacopoeia that the functions of leeches are breaking the blood and stimulating the menstrual flow, dispelling accumulation and dissipating syndrome, reducing swelling and detoxification, etc. Therefore, the development of leech farming has good market prospects and economic benefits. At present, Chinese patent medicines made from leeches have been mass-produced, and the supply is in short supply. The domestic demand for dried leeches reaches thousands of tons every year, so the demand for leeches increases year by year. With the extensive use of chemical fertilizers and pesticides, coupled with the predatory capture of leeches, the resources of wild leeches are decreasing day by day, which is far from meeting the needs of being used as medicine. As a result, artificial breeding has been carried out in many places. Existing artificial breeding all takes field or pond as breeding environment, uses breeding box to raise.

A Chinese utility model patent "leech breeding box" (publication number: 2927687; publication date: August 1, 2007) provides a leech breeding box, which includes a netted bottom with mesh and a bottom edge Escape prevention net with edges extending upwards. A protrusion extending toward the center of the net is provided on the top of the inner wall of the escape prevention net to prevent leeches from escaping. According to the analysis, it can be seen that the anti-escape performance of the breeding box is poor. Because leeches have a strong ability to escape, leeches have powerful suction cups, and through their unique inchworm movement (that is, bending and stretching like an arch bridge when crawling), they can easily cross the escape net. Especially in rainy days, when the anti-escape net is relatively wet, under the action of water droplets, the sucker of the leech has a stronger adsorption force, and it is easier to escape, thereby affecting the yield. In addition, the breeding box can only be used for raising leeches, and cannot be used for breeding leeches, which makes the breeding of leeches more complicated.

A Chinese utility model patent "An Ecologically Environmentally Friendly Leech Breeding Box" (publication number: 203353477U; public date: December 25, 2013) provides an ecologically friendly leech breeding box, the upper part of the breeding box is not added Cover, there is a nylon filter in the breeding box, the nylon filter is designed according to the shape of the box, and the top layer is controlled by a slide fastener to prevent leeches from escaping. It can be seen that the nylon filter screen designed by this breeding box can effectively prevent leeches from escaping. But it has obvious disadvantages: the first, this breeding box can only be used for leech raising, can not be used for leech breeding;
