Problems solved by technology

[0003] Leeches have strong adaptability. Artificial breeding of leeches is not restricted by regional conditions. They can be raised in ponds or pits, etc. When feeding, the feed is directly put into the feeding pond. In use, the natural living environment of leeches has been seriously polluted. Due to factors such as the natural environment and natural enemies, the hatching speed of leeches is 15-25 days, and the hatching rate is low, which seriously limits the process of large-scale breeding of leeches.

Embodiment 1

[0016] A method for artificially hatching leeches without soil, the method has the following steps:

[0017] (1) Prepare the incubator;

[0018] Select an uncovered box made of wooden material, place a layer of coarse sand with a thickness of 2.5 cm and a humidity of 35% at the bottom of the box, and spread the non-woven fabric matrix 2 with a thickness of 2 cm on the above-mentioned coarse sand layer 1. 2 Humidity is 35%; Laying bottom surface and the thickness of four walls on the substrate 2 are grid-shaped water-absorbing and moisturizing layer 3 with a thickness of 0.5cm. 3. The humidity is 35%. The upper part of the incubator is covered with black fabric. 4. The humidity of the air in the box is kept at 75-85%. It is convenient for farmers to quickly add or subtract humidity or temperature in the box; the overall height of coarse sand layer 1, non-woven fabric matrix layer 2 and water-absorbing and moisturizing layer 3 is half of the inner height of the box, which is co...

Abstract

The invention relates to the technical field of leech cultivation, in particular to an artificial soilless leech hatching method. The method comprises the two steps of preparation of a hatching box and placement of egg cocoons. According to the technical scheme, preying on leech larvae by natural predators such as birds and fishes and restriction on hatching of the leech egg cocoons by conditions such as strong sunlight and rainstorm under the condition of natural hatching can be avoided, the leech egg cocoons can hatch under the stable condition, the hatching speed and the hatchability can be effectively improved, the hatching time is unified, difference of hatched larvae can be reduced effectively, centralized management and collection are facilitated, and the effective utilization rate of resources is improved.

Description

technical field [0001] The invention relates to the technical field of leech cultivation, in particular to a method for artificially hatching leeches without soil. Background technique [0002] Leech is recognized as a high-quality and precious Chinese medicinal material in the field of traditional Chinese medicine. It is recorded in "Chinese Pharmacopoeia" that leech has the effect of "breaking the blood and stimulating the menstrual flow, eliminating fatigue and eliminating addiction. The treatment of injury is the main raw material of many traditional Chinese medicine formulas for the treatment of cardiovascular and cerebrovascular diseases. The natural hirudin made from the leech extract is a strong specific natural inhibitor of thrombin in the existing known anticoagulant substances, and the natural leech Hirudin has a very significant effect on dilating blood vessels, reducing blood viscosity and increasing blood circulation; it also has a good curative effect in the c...
