Problems solved by technology

Therefore, the existing technical achievements of leeches are also difficult to apply to the spawning and reproduction of Japanese medical leeches.
The natural fecundity of Japanese medical leeches is low, and the number of cocoons laid by the species of leeches after mating is small, and even the phenomenon of no egg-laying cocoons often occurs, which restricts the development of the industrialization of Japanese medical leeches and seriously affects the hearts of Japanese medical leeches as raw materials. Drug production for cerebrovascular diseases
However, the existing oviposition substrates have disadvantages such as low leech oviposition rate, easy breeding of pathogenic microorganisms, and poor reuse rate.

Embodiment 1

[0011] Example 1 Japanese medical leech spawning condition investigation 1

[0012] 1 material

[0013] 1.1 Test materials: Japanese medical leeches (provided by Chongqing Zhi Microbial Technology Co., Ltd.), coconut peat, and crushed forage.

[0014] 1.2 Test equipment: oxygenation pump, spawning water tank (1.0m (length) × 0.7m (width) × 0.7m (height))

[0015] 2 methods

[0016] 2.1 Selection of leeches and experimental design

[0017] From the Japanese leech breeding base, select Japanese leeches over 1 year old, with an individual weight of more than 0.5 grams, strong physique, sensitive response, and obvious reproductive rings for the oviposition test. After the experiment of each group, count the eggs under different conditions Condition.

[0018] The spawning water tank that is used for experiment, half puts water (the water level height is at 20cm), and the other half is covered with substrate. The part covered with the substrate is specifically: laying pebbles a...

Embodiment 2

[0041] Example 2 Japanese medical leech spawning condition investigation 2

[0042] According to the single factor investigation conditions described in Example 1, under conditions such as different spawning pH value conditions, spawning environment temperature, proportioning of spawning substrates, and water content of spawning substrates, the spawning rate of each group was counted, and the design Orthogonal experiments are shown in Table 4 and 5.

Abstract

The invention provides a special substrate for Japanese medicinal leech oviposition. The substrate is prepared from coconut chaff, smashed straw and water, and has the advantages of being capable of effectively increasing the Japanese medicinal leech oviposition number, lowering the pathogenic microorganism occurrence rate, being repeatedly utilized and the like. The substrate is applicable to pond large-scale oviposition and laboratory small-scale tests. The soil-free Japanese medicinal leech oviposition substrate has the advantages of effectively increasing the Japanese medicinal leech oviposition number, lowering the pathogenic microorganism occurrence rate and being convenient to recycle.

Description

technical field [0001] The invention relates to a leech oviposition substrate, in particular to a Japanese medical leech oviposition method and a special substrate thereof. [0002] technical background [0003] Japanese medical leech is the only leech medicinal material that likes to eat animal blood recorded in the "Chinese Pharmacopoeia". It contains the world's strongest natural anticoagulant drug-hirudin, which has the functions of breaking blood, removing blood stasis, and stimulating menstruation. Extremely strong, it is a classic of traditional Chinese medicine for promoting blood circulation and removing blood stasis in my country. Japanese leeches have unique curative effects in promoting blood circulation, removing blood stasis, stimulating menstrual flow, and anti-cancer, so that the supply of Japanese leech medicinal materials is in short supply. However, the large-scale development of medicines and the wide use of chemical fertilizers and pesticides have caused t...
