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 and leech product quality

Embodiment 1

[0055] A method for three-dimensional cultivation of leeches, specifically comprising the steps of:

[0056] 1. Prepare leeches: choose healthy, smooth, plump and elastic leeches as leeches;

[0057] 1.1. Purchase species of leech: The purchased species of leech should have a clearly raised reproductive zone between the male and female genital pores in the front of the body; the species of leech should be selected to enter the reproductive period to reach sexual maturity and have not laid eggs. There is no obvious gap between the genital pores The individual leeches with protruding reproductive zones are not suitable for breeding as seed leeches because they have not reached sexual maturity or have finished laying eggs. At the same time, the leeches with strong physique, smooth body surface, plump and elastic have strong viability and excellent reproductive performance, which is helpful for obtaining high-quality leeches. Yield, high quality leech eggs;

[0058]1.2. Prepare t...

Embodiment 2

[0083] The method for three-dimensional breeding of leeches comprises: preparing for planting leeches, temporarily raising leeches, preparing egg beds, throwing in, hatching, and cultivating, specifically comprising the following steps:

[0084]Prepare leeches: choose healthy, smooth, plump and elastic leeches as leeches. The age of leeches is 3 years, and the individual weight is 25g. Raised genital zone; add quicklime to a 150L opaque barrel for disinfection and wash it clean, lay 10cm of sterilized crushed coal ash on the bottom of the barrel, the particle size of the crushed coal ash is below 5mm, and then add 15cm of sterile Water, put 3Kg seed leeches in every 50L barrel according to the barrel capacity, seal the mouth of the barrel with 120 mesh gauze, and then load and transport. Take out the dead leeches, and take out the weak and weak leeches and raise them separately; the leeches should be selected to reach sexual maturity in the reproductive period and have not lai...

Abstract

The invention provides a method of stereoscopic breeding of leeches and belongs to the technical field of animal husbandry. The method includes: selecting qualified species of the leeches for temporary breeding; during temporary breeding, feeding snails in the morning and animals' internal organs in the evenly to the leeches; turning up sandy loam to create egg beds and dig drainage ditches; wetting the egg beds by spraying water and covering the same with straws; after putting the leeches to the egg beds for 18-21 days and 30-32 days, respectively sorting out leech eggs, placing the leech eggs down on the surface of hatching soil in hatching beds in a head-down manner, spreading the hatching soil on the eggs, spraying a dilute solution of salt on the surface of the hatching soil, and after hatching for 20-25 days, placing leech seedlings in paddy fields for breeding. The method has the advantages that ovulation quantity and egg quality of the leeches can be effectively improved through feeding in stages in time of temporary breeding, economic performance is enhanced; in addition, in the subsequent process of egg hatching, the occurrence of cleavage and hatching of seedlings is promoted, and the efficiency and economic benefit of leech and rice culture are improved through the stereoscopic breeding method.

Description

technical field [0001] The invention belongs to the technical field of animal breeding, and in particular relates to a method for three-dimensional breeding of leeches. Background technique [0002] Leeches, commonly known as leeches, have been recorded in "Shen Nong's Materia Medica", and have high medicinal value; they grow and reproduce in inland freshwater waters, and are traditional Chinese special medicinal aquatic animals. Used as medicine, it has the effects of treating stroke, high blood pressure, clearing blood stasis, amenorrhea, and traumatic injuries. In recent years, it has been newly discovered that leech preparations have special effects in the prevention and treatment of cardiovascular and cerebrovascular diseases and cancer. Historically, it was mainly caught by natural fishing. Due to the abuse of pesticides and chemical fertilizers in recent years, and the pollution of the environment by the "three wastes" of industry and agriculture, the wild natural re...
