The mode of applying is explained in detail.However, it will be understood by those skilled in the art that in each embodiment of the present invention,
In order that reader more fully understands that the application proposes many ins and outs.But, even if there is no these ins and outs and base
In following embodiment many variations and modification it is also possible to realize the application technical scheme required for protection.
The first embodiment of the present invention is related to a kind of earth boring auger of collection Scirpus mariqueter bulb Seedling, as shown in figure 1, this soil
Bore and include：Mobile jib 2 and the drill bit 3 being arranged at mobile jib 2 end that handle 1 is connected with handle 1；Wherein, drill bit 3 is in open circles
Tubular, one end of drill bit 3 is connected with mobile jib 2, and the other end of drill bit 3 has an opening.
In the present embodiment, handle 1, mobile jib 2 can be hollow cylindrical, the handle 1 of cylindrical shape, mobile jib 2 one aspect
Facilitate the gripping of collector, on the other hand reduce the weight of whole earth boring auger.But, present embodiment not should as limit,
Handle 1, mobile jib 2 can also be solid, or handle 1, mobile jib can also be other shapes.Present embodiment here differs
One illustration.
Specifically, in the present embodiment, handle 1 can be a diameter of 3cm hollow cylinder.Certainly, in present embodiment
Handle diameters should not be as limit.
It should be noted that for improving handle 1, mobile jib 2, the tightness being connected to each other of drill bit 3, in present embodiment
In, the centre position of handle 1 can be connected with the upper end of mobile jib 2 by way of annular solder, in addition, mobile jib 2 He
Drill bit 3 can also be linked into an integrated entity by annular solder mode.
In order to prevent sea water from entering by tube wall entrance handle 1 or by the junction entrance mobile jib 2 of handle 1 and mobile jib 2
And corrode whole earth boring auger, in the present embodiment, mobile jib 2 and handle 1, the welding of drill bit 3 number of times preferably twice.Certainly,
The number of times of above-mentioned welding can also be three times, four times etc., those skilled in the art can flexibly select as needed.
By the above, it is seen that, handle 1 is the sticking point when gathering bulb Seedling for the earth boring auger.Although extra large Rhizoma Sparganii
Grass natural habitat be wetland mostly, but the soil hardness of subregion still ratio is larger, in the gatherer process of bulb Seedling
Relatively elaborate.For enabling both hands gripping handle 1 simultaneously of collector, it is easy to have an effect in gatherer process, in this embodiment party
In formula, the length of handle 1 can be designed to 10cm, but present embodiment should not be as limit, and the length of handle 1 can also set
Count into 12cm；Or the length of handle 1 can also be designed to 15cm；Or the length of handle 1 can also be designed to 18cm；Or
The length of handle 1 can also be designed to 20cm.But the length of handle 1 not can exceed that 20cm, because the length of handle 1 is long,
The weight of earth boring auger, and the use of inconvenient collector can be increased.As long as handle 1 within the scope of 10～20cm for the length all exists
Within protection scope of the present invention.
In addition, during collection bulb Seedling, after earth boring auger insertion soil, needing to can be manually rotated earth boring auger makes core and underground
Soil is fully disconnected, and so just can collect complete bulb Seedling core.And the stress point of rotary handle 1 is in handle 1 and mobile jib 2

What bar 2 and handle 1 can connect is more closely all possible.
It is seen that, collector during using earth boring auger collection bulb Seedling, want and collector by the length of mobile jib 2
Height coupling, if the length of mobile jib 2 is oversize, is not easy to the shorter collector of height and uses, if the length of mobile jib 2
Too short, then collector needs constantly to bend over to use earth boring auger, the acquisition rate of impact bulb Seedling.For avoiding sending out of above-mentioned situation
Raw, in the present embodiment, the length of mobile jib 2 can be generally collector's height (height of general collector 150～
/ 3rd 190cm), i.e. 50～60cm.
It should be noted that in natural growing environment, the bulb that Scirpus mariqueter is not sprouted is typically distributed on underground 15
The depths of～20cm, the length of drill bit 3 just can collect the bulb do not sprouted, and this makes while not increasing cost,
Further increase the efficiency that Scirpus mariqueter population recovers and rebuilds.In the present embodiment, the length of drill bit 3 can be
25cm, diameter can be 6cm, but present embodiment should not be as limit, and the length of drill bit 3 can also be 30cm, diameter can
With the length being 8cm or drill bit 3 can also be 35m, diameter can be that the length of 10cm or drill bit 3 can also be
40cm, diameter can be 11cm etc..So, in the present embodiment, the height that space is left at the top of drill bit 3 is 5cm.
The benefit leaving the space of 5cm can avoid bulb Seedling to be extruded in gatherer process.Certainly, space is left at drill bit 3 top
The length of height and drill bit 3 is directly proportional.Not of uniform size in view of bulb Seedling, the length of drill bit 3 can be big according to bulb Seedling
Little arranging.
In addition, when gathering bulb Seedling in sabkha, for reducing seawater corrosion earth boring auger, increasing the service life of earth boring auger, handle
1st, mobile jib 2 and drill bit 3 can be that 304 stainless steels for 2mm process by thickness.But present embodiment should not
As limit, the thickness of 304 stainless steels can also be 3mm or can also be 4mm.
It is noted that rotating earth boring auger for ease of collector, in the present embodiment, handle 1 is connected with mobile jib 2
One end in T shape structure vertical with drill bit 3.
Compared with prior art, in present embodiment, gather bulb Seedling by using earth boring auger, a people can complete, operation
Convenient, collecting efficiency is high；The bulb Seedling transplanted using earth boring auger, the attached soil of its root system, again need not be colonized in soil after transplanting, energy
Enough rapidly adapt to the environment after transplanting, survival rate is high, reduces the management cost after transplanting；Single core is done to Natural Population
Disturb less, thus mitigating the destruction to Natural Population.
Second embodiment of the present invention is related to a kind of earth boring auger of collection Scirpus mariqueter bulb Seedling.Second embodiment is
Optimization to first embodiment, is in place of main optimization：For ease of bulb Seedling being taken out from drill bit, improving collection effect
Rate, in second embodiment of the invention, as shown in Fig. 2 a font opening is had on the outer surface of drill bit 3 naturally it is also possible to
It is the opening of other shapes, present embodiment should not be as limit.In addition, for enabling drill bit 3 quickly to insert in soil, increasing
Plus earth boring auger service life, save in gatherer process firmly, in second embodiment of the invention, drill bit 3 is away from mobile jib 2
One end is pointed.
It should be noted that in the present embodiment, the width size of the MENZI shape opening that the outer surface of drill bit 3 opens up
Can be the half of drill bit 3 diameter, i.e. 3cm.Certainly, the big I of width of the MENZI shape opening outer surface of drill bit 3 opening up
To be 1/3rd of drill bit 3 diameter, i.e. 2cm.Present embodiment is not limited.
Third embodiment of the invention is related to the soil described in a kind of use first embodiment or second embodiment
The method of drilling collection bulb Seedling, as shown in figure 3, specifically comprise the steps of：
Step 101：Collection bulb Seedling
In the natural habitat of Scirpus mariqueter, with earth boring auger, bulb Seedling is taken out (1 plant of bulb Seedling/soil in the form of core
Core).During collection bulb Seedling, the quantity of every square meter collection should be less than or is equal to 15, and collection position also should be uniformly distributed as far as possible, with
Exempt from the natural habitat of Scirpus mariqueter is damaged.Bulb Seedling loads in transporting box, after being transported to reconstruction regions, needs to place
Standby in shady place；
Step 102：Plantation bulb Seedling
In reconstruction regions, can plant by the interval of 50cm × 50cm, corresponding planting density is calculated as follows：0.07 hectare ≈
666 square metres, one square metre=10000 square centimeters；
The planting density of bulb Seedling：(666 × 10000) ÷ (50 × 50)=2664 plant；That is, if with the interval kind of 50cm
Plant, about 2664 plants of bulb Seedling can be planted in every mu of ground, that is, every square meter plants 4 plants of bulb Seedling.But this embodiment party
Formula should not be as limit it is also possible to plant according to the spacing of 100cm × 100cm (i.e. planting density is 1 plant of bulb Seedling/square meter)
Plant.During plantation, first with earth boring auger, one core hole is got out on reconstruction regions, then the core with bulb Seedling is inserted core hole
In, that is, complete the plantation of bulb Seedling.
It is noted that if the depth in core hole is more than the height of core, the bulb Seedling in core is less than earth's surface, that
May result in bulb Seedling waterflooding dead；If the depth in core hole is equal to the height of core, and when planting, core is not fully inserted into
In hole, then making hole internal water accumulation, thus leading to the bad root phenomenon of bulb Seedling, reducing the survival rate of bulb transplantation of seedlings；If native
The depth in core hole is less than the height of core, then the bulb height of seedling in core goes out earth's surface, can reduce bulb Seedling by the probability of water logging, enter
And promote bulb Seedling fast-growth and diffusion.In the present embodiment, the depth in core hole is less than bulb Seedling core 3cm.Certainly,
The depth in core hole less than bulb Seedling core 4cm or can also can also be 5cm.Present embodiment should not be as limit.
It should be noted that being transported to the bulb Seedling of reconstruction regions, need to plant as early as possible, for the inconvenience avoiding core deformation to lead to
In plantation, in the present embodiment, can not water to the bulb Seedling in core before plantation.
Further, since plum rain season will increase bulb Seedling by drowned probability, reduce survival rate, therefore during the transplanting of bulb Seedling
Between can not be later than May, in the present embodiment, the transplanting time of bulb Seedling can be in 4 annual～May.
It is seen that, during transplanting, the height of seedling of bulb Seedling is unsuitable excessive, otherwise easily makes during transplanting
Become bulb Seedling fibrous root impaired, thus reducing the survival rate of bulb Seedling.For avoiding the appearance of the problems referred to above, in present embodiment
In, the height of seedling of transplanted seedling is maintained at 1～5cm as far as possible.
Compared with method for transplanting of the prior art, the earth boring auger method for transplanting in present embodiment has the advantage that：
1st, easily obtain：In silt coast habitat, gather bulb Seedling using earth boring auger, a people can complete, obtain efficiency
High；
2nd, easily transport：Bulb Seedling core profile rule, lighter in weight, convenient transport；
3rd, easily plant：During plantation, it is inserted directly in the core hole of equal area size；
4th, growth, diffusion velocity are fast, and survival rate is high：The bulb Seedling that earth boring auger is transplanted, the attached soil of its root system, need not be in soil after transplanting
Again it is colonized in earth, the environment after transplanting can be rapidly adapted to, survival rate is high, growth and diffusion velocity are fast.Scirpus mariqueter ball
The optimal transplanting time of stem Seedling is 4～May, avoids the drowned problem of seedling that the long-time rainfall in plum rains time causes.In addition,
The adaptive time after greatly shortening bulb transplantation of seedlings transplanted by earth boring auger, grows higher before rainy season set, it is to avoid because long-time
It is submerged in rainwater dead, increased the success rate of reconstruction, because of water table management and the one-tenth of reseeding generation after reducing transplanting
This；
5th, rebuild efficiency high：In view of the fast feature of Scirpus mariqueter growth, diffusion velocity, the method presses two kinds of spacing kinds
Plant bulb Seedling, the Mean density to growth end of the season Scirpus mariqueter can reach 1200 plants/square meter and 800 plants/square meter respectively.Root
According to experimental result, in reconstruction regions, the Mean density of 1200 plants/square meter has reached Carrying capacity (i.e. population maintenance
Maximal density, exceed the death that this density will lead to Scirpus mariqueter plant).In addition, too high initial seeding density,
The waste of raw material will be led to；
6th, little to the destruction of Natural Population：It is deep that the collection of single core is only limitted to a diameter of 6cm to the interference of Natural Population
Spend the region for 20～25cm, the core hole retaining after collection can be buried by the silt in sea water, the trample effect of collector
Should be also by clear-cutting forestland in 3～5 days.It is on the verge of in the habitat of extirpation to transplant bulb Seedling, the party in Scirpus mariqueter population
Method is particularly suitable.
It will be understood by those skilled in the art that the respective embodiments described above are to realize the specific embodiment of the present invention,
And in actual applications, can to it, various changes can be made in the form and details, without departing from the spirit and scope of the present invention.
