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

The method of artificial soilless leech hatching

Technical field

The present invention relates to a kind of method of hirudiniculture technical field, particularly artificial soilless leech hatching.

Background technology

Leech is the first-class rare traditional Chinese medicine that Chinese medicine circle is generally acknowledged, in < < Chinese pharmacopoeia > >, record leech and have " broken blood stimulates the menstrual flow; by the curative effect of the tired addiction that disappears; be usually used in blood tired through closing, the treatment of lame addiction lump in the abdomen, hemiplegia or injury from falling down, be the primary raw material of the Chinese medicine preparation of numerous treatment cardiovascular and cerebrovascular diseases.The natural hirudin that hirudo extract is made is fibrin ferment specificity natural inhibitor stronger in existing known anticoagulative substance, natural hirudin for hemangiectasis, reduce blood viscosity, to increase sanguimotor effect very remarkable; In the clinical practice of the diseases such as treatment hypertension, headstroke, coronary heart disease, arterial thrombus, also there is good curative effect.Except hirudin, leech also contains the nutriments such as hyaluronidase, vasodilatin, prostaglandin isoreactivity material and essential amino acid.

The adaptability of leech is stronger, artificial feeding leech is not subject to regional condition restriction, can be on the spot in pond pond support or support etc. in hole, during nursing, feed is directly dropped into and feed in pond, due to a large amount of uses of the farmland products applied such as agriculture chemical in recent years, the Natural Survival environment of leech has been subjected to serious pollution, due to factors such as natural environment and natural enemies, the hatching speed of leech is 15-25 days, and incubation rate is lower, has seriously limited the process of large-scale farming leech.

Summary of the invention

The technical problem to be solved in the present invention is: a kind of method that cost is lower, can improve the artificial soilless leech hatching of leech hatching speed and hatching quantity is provided.

The technical solution adopted for the present invention to solve the technical problems is: a kind of method of artificial soilless leech hatching, and the method has following steps:

(1) prepare incubator box

Select the uncovered casing of plastics or wooden materials, at bottom half, place the rough sand that one deck 2-3cm is thick and humidity is 30-40%, the nonwoven matrix that is 1.5-2.5cm by thickness is laid on above-mentioned rough sand layer, and soil humidity is 30-40%; The latticed water suction moisturizing layer that the thickness of laying bottom surface and wall in matrix is 0.5-1.5cm, the sizing grid of water suction moisturizing layer is the suitable one piece of Whitmania pigra Whitman spawns of putting into, moisturizing layer humidity 30-40%, incubator box top is covered with black fabric, in casing, the humidity of air remains on 75-85%, and wall box is hung with for monitoring at any time the Hygrothermograph of environment in case.

(2) place ovum cocoon

The grid that Whitmania pigra Whitman spawns is placed in to above-mentioned casing, temperature setting is set to 20-25 ℃, treats young leech cocoon-break.

Further, for making Whitmania pigra Whitman spawns, comparatively fast hatch, the light transmittance of the black fabric that the described hatching initial stage adopts is 10-20%, the light transmittance of the black fabric of hatching employing in mid-term is 20-30%, the light transmittance of the black fabric that the hatching later stage adopts is 30-60%, and the grid of water suction moisturizing layer is square, rhombus or circle.

Beneficial effect: technical scheme of the present invention can effectively be avoided the predations of natural enemy to the leech young such as bird under nature incubation condition, fish, the restrictions of condition to hatching Whitmania pigra Whitman spawns such as strong daylight, heavy rain, Whitmania pigra Whitman spawns can be hatched under comparatively stable condition, can effectively improve hatching speed and hatchability, unified brooding time, can effectively reduce the difference of hatchling, be beneficial to centralized management and gather, improve utilization of resources rate.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the present invention is further described;

Fig. 1 is structural profile schematic diagram of the present invention;

In figure, 1. coarse sands layer, 2. nonwoven matrix layer, 3. water suction moisturizing layer, 4. black fabric, 5. digital display type Hygrothermograph.

Embodiment

Embodiment mono-

A method for artificial soilless leech hatching, the method has following steps:

(1) prepare incubator box;

Select the uncovered casing of wooden materials, at bottom half, place the rough sand that one deck 2.5cm is thick and humidity is 35%, the nonwoven matrix 2 that is 2cm by thickness is laid on above-mentioned rough sand layer 1, and matrix 2 humidity are 35%; The latticed water suction moisturizing layer 3 that the thickness of laying bottom surface and wall in matrix 2 is 0.5cm, the sizing grid of water suction moisturizing layer 3 is the suitable one piece of Whitmania pigra Whitman spawns of putting into, water suction moisturizing layer 3 humidity 35%, incubator box top is covered with black fabric 4, in casing, the humidity of air remains on 75-85%, wall box is hung with for monitoring at any time the digital display type Hygrothermograph 5 of environment in case, thereby can facilitate poultry feeders fast to plus-minus humidity in case or plus-minus temperature; Coarse sands layer 1, nonwoven matrix layer 2 and water suction moisturizing layer 3 overall height are half of box inside height, and the young leech that is conducive to hatch is climbing upwards.

(2) place ovum cocoon and Whitmania pigra Whitman spawns is placed in to the grid of above-mentioned casing, temperature setting is set to 20-25 ℃, treats young leech cocoon-break.

For making Whitmania pigra Whitman spawns, comparatively fast hatch, effectively improve hatching speed and hatchability, the light transmittance of the black fabric 4 that the hatching initial stage adopts is 10-20%, the light transmittance of the black fabric 4 of hatching employing in mid-term is 20-30%, the light transmittance of the black fabric 4 that the hatching later stage adopts is 30-60%, and the grid of water suction moisturizing layer 3 is square.

The above-mentioned foundation desirable embodiment of the present invention of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this invention technological thought, carry out various change and modification completely.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to claim scope.
