Background technology
Cordyceps sinensis is that aweto (Cordyceps sinensis) infects and colonize in Hepialidae insect larvae
On the stroma (fructification) that grows and larva polypide complex, belong to edible fungi, be that China is a kind of traditional famous and precious
Tonic Chinese herbal medicine material, there is the multiple efficacies such as regulation function of immune system, antitumor, antifatigue.
It is contour that wild Cordyceps sinensis is only grown in the mesophorbium, coryphile of Qinghai-Tibet height above sea level 3000-5000 rice, plateau grassy marshland
In cold vegetation, because in recent years excessively excavation declines its yield, its price has gone up more than 1000 compared with before more than 20 years
Times.Therefore, China scientific research personnel carrying out always using aweto infect bat moth larvae artificial cultivation of cordyceps come
The study on the industrialization of wild cordyceps is substituted, tries hard to allow the Cordyceps sinensis of costliness to come into common people house.
The necessary condition of artificial feeding bat moth larvae is the need for the environment of suitable larval growth, and suitable soil can be
Larva provides normal growing environment, but the soil moisture of breeding grub is easily lost in, so that wet needed for larval growth
Spend low, be easily caused dead larvae.
Currently without the soil air-humidification method that particularly suitable process is cultivated to Cordyceps sinensis, spray water or the mode watered
Ground moistening can not quantitative, be uniformly made, the distribution for being easily caused Hepialidae larva is also uneven, or even excessively concentrates, extremely
Rate of dying is higher.
The content of the invention

Soil matrix damping device for bat moth larva raising provided by the present invention, can it is deep according to soil, wide,
Height, selects suitable device physical parameter;According to the humidity of soil, suitable water consumption is selected, soil is implemented to humidify, should be added
Wet uniformly implemented along deep subsoil to top layer;During the water shortage of soil local, can accordingly implement local humidification;The device can
Quantitatively, position, the soil of giving of timing is humidified, and cause the soil moisture for raising bat moth larvae uniform, so that its growth divides
Cloth is uniform, survival rate increase.
The course of work:
1. barrier switch is lifted up, hollow out dislocation, prevents aperture from permeable on aperture and baffle plate;
2. the switch of water receiver is opened, makes water be full of following water-permeable pipe;
3. full of barrier switch is pressed down after water-permeable pipe, barrier switch makes place's closing, aperture and baffle plate on water-permeable pipe to water
Hollow out is overlapped, and now water spills from aperture in water-permeable pipe, and by osmosis ground moistening is made;
4. after pressing barrier switch 2~4 minutes, piston is pulled up, after piston runs into stuck point, is stopped 2~4 minutes,
Pull up again, stuck point is run into every time and is stopped 2~4 minutes, until last stuck point (completes whole permeable process needs 1~2 little
When), so that the appearing from below to up of the water in water-permeable pipe, makes soil relatively evenly soak, reaching makes soil average
Keep the skin wet, be that next time breeding grub makees moisture-keeping function;
5. after being finished the water in pipe, baffle plate is carried upwards, prevent larva from entering aperture;
6. once humidified every two weeks.
Embodiment:The device of different size and different water consumptions carry out humidification detection:
The present embodiment raise host of Cordyceps sinensis bat moth larvae during, using 32cm × 32cm × 20cm support
Worm box is raised, and using the sterile soil after sterilization as foster worm soil, is mixed with feed and water after sterilizing, and soil is transferred to conjunction
Suitable humidity;2-3 instar larvae 100-200 bars are selected, is put in box, observed 1~3 month.
Soil damping device is inserted into insect box before larva is thrown in, carries out humidifying soil, without the need for taking out.Plus wetted perimeter
Phase is for biweekly.
The device of different size, refers under identical amount of water, and the distance in damping device two-by-two between water-permeable pipe is changed
Become, specification is 13cm, 14cm, 15cm, 16cm, 17cm.
Different water consumptions, refer in the damping device of same specification, the identical water consumption of addition, and water consumption is:800g,
1000g, 1200g, 1400g, 1600g, 1800g, 2000g;The number of the present embodiment water-permeable pipe be 4, the volume of water-permeable pipe with
Water consumption matches.

Conclusion:From above-mentioned experimental result, for the insect box of 32cm × 32cm × 20cm, required water optimised quantity is
1600g, in the case where the larva water yield is met, for the insect box, the water-permeable pipe distance of 15cm, 16cm, 17cm can make water more
Uniform wetting soil, improves survival rate of larvae.
When the insect box of different size is selected, suitable perspective pipe distance can be selected by above-mentioned rule, and be selected
Suitable water-permeable pipe size is adapting to different water consumptions.
