Embodiment
The present invention is further detailed explanation in conjunction with the accompanying drawings and embodiments now, and these accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of leech emerges breeding arrangement, comprise: nursery pond 1, be arranged on the aerator in nursery pond 1 and swim in and educate bed 3 in nursery pond 1, nursery pond 1 inner wall surface is smooth, the Chi Kou edge on nursery pond 1 top is provided with cover rim 2, and cover rim 2 was around pond mouth one week, and the width of cover rim 2 extends a segment distance inside nursery pond 1, educate on bed 3 and be placed with leech egg ovum 7, and adopt wet cloth 8 to cover on leech egg ovum 7.
Educating bed 3 swims in nursery pond 1, for leech seedling provides a best temp. and humidity environment, educate water extraction bottom bed 3 for best incubation temperature, more than the water surface and the covering of wet cloth 8 a best humidity environment is provided, moistening environment can stimulate the hatching broken shell of leech seedling simultaneously.
The structure of cover rim 2 can stop that the leech seedling creeped climbs out of nursery pond 1 Chi Kou upward, prevents leech seedling from climbing from nursery pond 1, when seedling climbs to cover rim 2 edge, due to angle, can fall the water of meeting nursery pond 1 from cover rim 2.
Wall energy easy cleaning nursery pond 1 in smooth nursery pond 1, or nursery pond 1 is carried out disinfection cleaning.
Nursery pond 1 inwall that cement is piled up posts marble slab, the smooth surface of marble slab.Marble slab material is natural, harmless to leech seedling, simultaneously cleaning and sterilizing nursery pond 1, and marble slab is also comparatively durable.
Educate bed 3 for cystosepiment 4, cystosepiment 4 is covered with one deck screen cloth 6, the leech egg ovum 7 being coated with wet cloth 8 is placed on screen cloth 6, and cystosepiment 4 center is provided with recessed bowl structure 5 downwards, and bowl structure 5 lay is close to by screen cloth 6.Cystosepiment 4 can swim in sleep, and simultaneously for leech seedling provides a preferably environment of hatching, leech seedling hatching broken shell can be climbed to easily in the water of nursery pond 1 along cystosepiment 4, increase emergence rate after emerging.
Wet cloth 8 is cotton material, the wet cloth 8 of plane materiel matter covers leech egg ovum 7, native fiber has good affinity, screen cloth 6 aperture is 0.5cm, the pore size of screen cloth 6 can agree with the size of leech egg ovum 7, is deposited in the egg ovum on screen cloth 6 and is not easy to slide due to the reason of mesh, leech egg ovum 7 can be made to pile higher a pile, there is provided good environment of hatching, the leech egg ovum 7 be stacked is conducive to hatching.
The length of nursery pond 1 be 8m, wide be 2m, the size of nursery pond 1 reasonably can control the leech seedling numbers hatched together in nursery pond 1, is conducive to the counting of later stage when selling.Cover rim 2 width stretched to inside nursery pond 1 is 5-10cm.The size impact of such width on Chi Kou is less, and leech is also not easy to cross cover rim 2 and climbs out of nursery pond 1 simultaneously.
Between cover rim 2 and nursery pond 1 side, angle is 10-90 °, and such angle leech seedling cannot cross cover rim 2.Be provided with thermostat in nursery pond 1, or the external environment condition at nursery pond 1 place is provided with thermostat, the water temperature in nursery pond 1 can remain in predetermined temperature range by thermostat.Thermostat is the steam heater of boiler or carries out temperature adjustment by passing into warm water to nursery pond 1.Also air-conditioning can be adopted to carry out temperature adjustment to the greenhouse residing for nursery pond 1 simultaneously, ensure the temperature in nursery pond 1.
What use leech to emerge breeding arrangement goes out a seeding cultivating method, comprises the following steps:
(1) in nursery pond 1, inject the warm water of nursery, opening aerator is nursery pond 1 oxygenation;
(2) take the leech egg ovum 7 of predetermined weight, be placed on and educate on the screen cloth 6 of bed 3, then cover leech egg ovum 7 with wet cloth 8, treat leech broken shell;
(3), after the whole broken shell of leech, folding screen cloth 6 once, collects eggshell and cleans out nursery pond 1;
(4) the leech seedling after hatching in nursery pond 1 being emerged all migrates out nursery pond 1, closes aerator, the oxygenation of leech seedling is packed.
Warm water in step (1) is
20-25degree Celsius, preferably
23degree Celsius, at this temperature, the hatching seedling effect of leech egg ovum 7 is best.
Above according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, related personnel in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on specification, must determine technical scope according to right.
