Hatching and opening integrated technology for whitmania pigra

Abstract

The invention relates to the field of whitmania pigra hatching, in particular to a hatching and opening integrated technology for whitmania pigra. The method includes the following steps that 1, a hatching room is constructed; 2, a hatching box is placed; 3, whitmania pigra egg capsules are selected; 4, pomacea canaliculata egg masses are put for hatching for 4-7 days; 5, the whitmania pigra egg capsules are put for continuous hatching. The hatching and opening integrated technology for whitmania pigra realizes soilless hatching; compared with a traditional hatching technology, the larva emerging time of the whitmania pigra is more concentrated, collecting and transferring are also more convenient, management is convenient, and the survival rate is higher; meanwhile, pomacea canaliculata is hatched in the hatching box in advance, opening is directly performed after hatching and larva emerging of the whitmania pigra, culture techniques are reduced, and labor is saved.

Description

technical field [0001] The invention relates to the field of leech hatching, in particular to the integration technology of wide-body gold wire leech hatching openings. Background technique [0002] Medicinal leeches are traditional precious Chinese medicinal materials in my country. Leeches have a long history of being used as medicines. They have been recorded in the famous Chinese medical books "Shen Nong's Materia Medica" and "Compendium of Materia Medica". , can treat hypertension, coronary heart disease and tumors. At present, medicinal leeches are mostly used in the treatment of diseases of the human and cerebrovascular systems, to prevent the occurrence of human and cerebrovascular thrombosis, and to reduce blood viscosity. The prospect of leech farming is very broad. The wide-bodied golden leech Whitmaniapigra Whitman is the preferred species for medicinal leeches because of its large size, fast growth and high medicinal value.

AI Technical Summary

Problems solved by technology

When the cocoon is hatched, it usually imitates its natural environment and is placed in moist soil for incubation. However, in practice, the incubation time can sometimes be as long as 20 days, and the soil tends to dry out, causing the cocoon to die.

Therefore, the method of spraying water is often used in production to maintain soil moisture, but the spawning time of the wide-bodied golden leech is inconsistent, and the development of egg cocoons is not uniform, and the mature ones will drill out when stimulated during the spraying process. egg cocoon

The seedlings that have emerged from the cocoon are very active and will crawl around. Some will die directly when they climb to the surface of the soil due to drying, and some will directly climb out of the incubator, resulting in loss of seedlings.

Some producers even apply toothpaste around the incubator in order to prevent the seedlings from crawling out, but the toothpaste flows into the incubator with the water during the spraying or operation process, often resulting in a large number of deaths, sometimes reaching 60-80%

The research found that the first hatched seedlings are forced to stay in the incubator and cannot eat in time, which will seriously affect the survival rate and growth rate
