Embodiment
With reference to specific examples below and accompanying drawing, the invention will be described in further detail.Implement process, the bar of the present invention
Part, experimental method etc., it is the universal knowledege and common knowledge of this area in addition to the following content specially referred to, the present invention
Content is not particularly limited.
The present invention proposes a kind of method for separating in habitat soil seed bank from bare area and killing non-purpose vegetable seeds, bag
Include following steps：
Step 1：Investigate in specific bare area habitat soil seed bank, the presence of purpose plant and non-purpose vegetable seeds
Situation (the particularly ratio situation of the total amount of all vibrant seeds, purpose plant and non-purpose vegetable seeds in seed bank),
And the diameter difference degree of purpose plant and non-purpose vegetable seeds, and the difference degree of their seed specific weight.
Step 2：According to the difference degree of the diameter difference and seed specific weight of purpose plant and non-purpose vegetable seeds, divide 4
Kind situation：
A) when in described specific bare area habitat soil seed bank, the diameter difference of purpose plant and non-purpose vegetable seeds
Significantly, when and their seed specific weight difference is not notable：
Pass through analysis purpose plant and the diameter difference of non-purpose vegetable seeds, the sieve of selection or customization with special pore size distribution
Sub- a, a are made up of stainless steel or other flexibles, firm, non-corrosive, durable material.Sieve a can be by bare area habitat soil
Purpose plant and non-purpose vegetable seeds are effectively separated in earth seed bank, i.e., one type seed can be by sieve aperture, separately
A kind of seed can not pass through sieve aperture.
According to actual conditions such as the size of the seed Screening Treatment workload and crew numbers and appointed conditions,
Determine the parameters such as the breadth of sieve, volume, weight.
In order to reduce labor intensity, the equipment such as motor machine or hydraulic jack can be used, are aided in into luggage soil, agitation
Soil, vibrations sieve propose the work such as drop sieve.
In order to improve the seed screening efficiency, can arranging the serial sieve of aperture from big to small, (wherein sieve a is in
Afterbody).First filter out the object being relatively large in diameter by large aperture sieve b (for soil block, need to crush, so that wherein as far as possible
The screening that the seed that may be mixed with can have an opportunity by next step), finally by the sieve a of special pore size distribution, by purpose plant
It is effectively separated with non-purpose vegetable seeds, i.e., one type seed does not pass through sieve aperture by sieve aperture, another kind of seed.
For two kinds of In The Soils, using distinct methods, non-purpose vegetable seeds and purpose vegetable seeds are separated：
When bare area habitat soil dry when for loose type soil when, to the soil containing vegetable seeds in bare area habitat
Earth, it is directly separated non-purpose vegetable seeds and purpose vegetable seeds.
When bare area habitat soil dry when for non-loose type soil when, to the soil containing vegetable seeds in bare area habitat
Earth, sufficient Soaking treatment need to be first carried out, i.e., soaked the soil containing vegetable seeds in bare area habitat in water, with the molten soil that disappears
Particle, and then the non-purpose vegetable seeds of separation and purpose vegetable seeds.
B) when in described specific bare area habitat soil seed bank, the diameter difference of purpose plant and non-purpose vegetable seeds
Not significantly, and during their seed specific weight significant difference：
To the seed of the various plants in bare area habitat soil, large sample sampling, the different interseminal proportions of test are carried out
Difference degree, by theory analysis and the experimental check of series concentration water salting liquid, it is determined in bare area habitat soil
The specific water that the seed (being especially non-purpose vegetable seeds and purpose vegetable seeds two major class) of various plants is effectively separated
The concentration b of salting liquid.
According to the size of vegetable seeds mask work amount in bare area habitat soil, it is determined that and it is b to make for containing concentration
Specific water salting liquid container c.
By the bare area habitat soil containing various vegetable seeds, it is the specific of b to be progressively loaded with concentration described in appropriate loading
In the container c of water salting liquid.In the process, it is stirred continuously, so that up to being sufficiently mixed, observation seed separates situation up and down, passes through
Differentiate, the vegetable seeds for floating on solution upper strata is constantly taken out, treat container c lower floors alluvial soil and seed mixture d compared with
During seed mask work that is more and influenceing solution upper strata, then the soil of container c lower floors alluvial and the mixture d of seed are taken out.Through
Cross this process, the purpose plant and non-purpose vegetable seeds in bare area habitat soil realize separation.
Similar approach was once chosen seeds early in monocrop and used in work, but the non-mesh in bare area habitat soil is removed
Vegetable seeds when, there is not yet the report using the above method.The above method is not the existing method of simple transplanting, and is intended to
Except the non-purpose vegetable seeds in bare area habitat soil seed bank, therefore, occasion, condition and purpose are different, and process is also inconsistent,
With novelty.
C) when in described specific bare area habitat soil seed bank, the diameter difference of purpose plant and non-purpose vegetable seeds
With difference of specific gravity it is notable when：
For the situation of purpose plant and non-purpose vegetable seeds in specific bare area habitat soil seed bank, from A and B institutes
Between the method stated, simpler, more easy, more effective way is selected.
For the situation of purpose plant and non-purpose vegetable seeds in specific bare area habitat soil seed bank, if in A
Between the method described in B, it is difficult to select the method more optimized, then between the method described in A and B, discharge precedence (ratio
As first used A, selecting B afterwards, or conversely).
D) when in described specific bare area habitat soil seed bank, the diameter difference of purpose plant and non-purpose vegetable seeds
With difference of specific gravity it is not notable when, then need to explore and screen and kill the other method of non-purpose vegetable seeds.
Step 3：After undergoing the above-described steps, non-purpose vegetable seeds and purpose plant in bare area habitat soil seed bank
Seed realize separation.Killing for the non-purpose vegetable seeds after separation, using physical method (as using the long period
High temperature, high pressure, freezing, water logging, or starvation suffocate the methods of to seed inactivate) and without secondary pollution chemical method (bag
Including all can kill non-purpose vegetable seeds and noresidue, to chemical agent of the environment without negative effect).
In the present invention, when process step 2 is to the purpose plant in bare area habitat soil seed bank and non-purpose vegetable seeds
, can be with when being still not sufficient enough to reach the target for separating non-purpose vegetable seeds and purpose vegetable seeds after carrying out first separation
The process of step 2 is repeated several times, until sufficiently achieving the target for separating non-purpose vegetable seeds and purpose vegetable seeds.
In the present invention, if planted by the purpose plant in one or many habitat soil seed banks to bare area and non-purpose
The separation process of species, purpose plant and non-purpose vegetable seeds, which are realized, to be kept completely separate, then ideal.But if by one
Secondary or multiple screening process, purpose plant and non-purpose vegetable seeds, which can not reach, to be kept completely separate, then has two kinds of situations：
In the present invention, fail to be kept completely separate when between non-purpose vegetable seeds and purpose vegetable seeds, but separated
A part in, non-purpose vegetable seeds and purpose vegetable seeds are with small percentage<40% is blended in for the moment, will can pass through
The Mischung containing non-purpose plant and purpose vegetable seeds after separation, sowing completely in the habitat of manual control, can treat
After seed is sprouted successively, by differentiating, connect root immediately and go unless purpose plant, sees by the long period (such as multiple Growing seasons)
Examine, after confirming that no non-purpose plantling occurs, confirm to remove non-purpose plant totally.At this moment for having grown
The purpose plant come, it is transplanted in the estimated habitat for implementing ecological recovery, continues to cultivate.
Fail to be kept completely separate when between non-purpose vegetable seeds and purpose vegetable seeds, but in a separated part
In, non-purpose vegetable seeds and purpose vegetable seeds are with larger proportion>40% when mixing：
If seed total amount is not very big in bare area habitat soil seed bank, screening can will be passed through similar to the above method
The Mischung containing non-purpose plant and purpose vegetable seeds after separation, sowing completely in the habitat of manual control, can treat
After seed is sprouted successively, by differentiating, connect root immediately and go unless purpose plant, sees by the long period (such as multiple Growing seasons)
Examine, after confirming that no non-purpose plantling occurs, confirm to remove non-purpose plant totally.At this moment for having grown
The purpose plant come, it is transplanted in the estimated habitat for implementing ecological recovery, continues to cultivate.
If seed total amount is very big in bare area habitat soil seed bank, and using the above method it is more difficult when, then need to change
Other method.So initial step one, two is very crucial, it is also critically important.
The protection content of the present invention is not limited to above example.Under the spirit and scope without departing substantially from inventive concept, this
Art personnel it is conceivable that change and advantage be all included in the present invention, and using appended claims as protect
Protect scope.
