Description

A kind of preparation method of resin embedding meat herbaceous plant sample
Technical field
The present invention relates to plant specimen preparation method, the preparation method for more particularly relating to meat herbaceous plant sample.
Background technology
Making the plant specimen used in current scientific research institution mainly has herbarium, dipping specimen.Herbarium is also known as Squeeze preparation, is the sample being made up of steps such as shaping-compacting-bookbinding-preservations, but the organ such as plant flowers and fruits be crushed it is viscous Together, it is difficult to dissect and observe.And change colour because being easy to aoxidize for a long time in air, it is impossible to it is long-term to preserve.Meat grass This plant is difficult to be preserved with the preparation method of herbarium because of its cauline leaf solid.Dipping specimen is plant through chemicals Immersion keeps the sample of original form, but the frangible and full liquid heavy greatly of specimen bottle volume used in anti-corrosive properties dipping specimen, Not readily transportable or carrying.Though in addition, the method for resin embedding plant specimen has been proposed, many methods using drying are handled A kind of teaching preparation method of resin sample that plant, such as Chinese patent CN105900977A provide, uses drier pair Plant is carried out after encapsulation dehydration, is reused resin and is embedded;But this method is not suitable for the plant of all kinds, esp meat Matter herbaceous plant, if carrying out processing meat herbaceous plant using seasoning, its loose meat cauline leaf, which morphologically occurs, to wither Compression deformation etc. is larger to be changed.In addition, Chinese patent CN105010302A provides a kind of system of the aqueous zoological specimens of resin embedding Make method, method carries out preservative treatment with impregnating fluid to aqueous zoological specimens;But this method can not keep the color of plant.Total From the point of view of, current meat herbaceous plant preparation of specimen technology relatively lacks.
The content of the invention
It is an object of the invention to provide a kind of preparation method of resin embedding meat herbaceous plant sample, it is intended to solves existing There is the problem of plant specimen preparation method is difficult to preserve meat herbaceous plant and not good meat herbaceous plant sample effect.
To realize purpose, the present invention is a kind of preparation method of resin embedding meat herbaceous plant sample, including following step Suddenly:
1) conventional pretreatment is carried out to meat herbaceous plant;
2) guarantor's color solution of different colours is configured, meat herbaceous plant is placed therein at progress dipping by color classification Reason;
3) the meat herbaceous plant handled well is taken out, rinsed with distilled water;
4) organic solution of various concentrations is configured, meat herbaceous plant is placed therein the organic replacement Treatment of progress;
5) the meat herbaceous plant handled well is taken out, removes the solution on surface;
6) the above-mentioned meat herbaceous plant handled well is placed in silica gel mould, embedded with resin;
7) after after hardening of resin, producing meat herbaceous plant resin sample.
Further, in step 1) in, it is described that the conventional pretreatment of meat herbaceous plant progress is referred to, by the meat of collection Herbaceous plant removes silt impurity and deadwood and rotten leaf, such as removes the dust on surface using hairbrush or elutes plant with clear water.For The fine hair on meat herbaceous plant surface, it should be noted that retain.
Further, in step 2) in, the common configuration method of described guarantor's color solution for different colours sample is as follows Table:
Green sample The formalin of 10% copper sulphate 0.5%
Yellow and light green color sample 0.15%~0.5% sulfurous acid
Red sample The formalin of 1% boric acid 1%
Bluish violet sample 2% aluminum sulfate solution
Further, in step 2) in, meat herbaceous plant sorting placement is subjected to impregnation process in guarantor's color solution, wherein, Plant need to be totally submerged in solution, the plant of collection can be uniformly put into non-woven bag, is pressed into the lump in solution;Its In, dip time is 12-24 hours, and specific time span can be depending on the carnification degree according to plant stem-leaf.Wherein, blade compared with Thick plant can extend dip time, to ensure color effect.
Further, in step 3) in, the meat herbaceous plant handled well is rinsed with distilled water, it is residual that rinsing removes plant surface Remaining guarantor's color solution.Rinsing time can not be long, is separated out to prevent protecting color solution.
Further, in step 4) in, the organic solution of described various concentrations is molten for the concentration gradient of ethanol and dimethylbenzene Liquid.Such as:The ethanol of the ethanol solution of 70% ethanol solution → 80% → 90% ethanol solution → absolute ethyl alcohol → absolute ethyl alcohol → 50% The diformazan of the xylene solution of the xylene solution of solution+50% → xylene solution of 25% ethanol solution+75% → 100% → 100% Benzole soln;
Meat herbaceous plant is positioned over organic solution and carries out organic replacement Treatment, soak time is in every kind of solution 20-30 minutes.
Further, in step 5) in, the solution for handling plant surface well is removed, can be using method of drying or blower fan drying method.
Further, in step 6) in, the resin is by epoxy resin and curing agent in mass ratio 2.9:1 uniform stirring is mixed After conjunction, stand 10 minutes bubbles and eliminate obtained resin naturally.
Further, in step 6) in, the above-mentioned meat herbaceous plant handled well is placed in silica gel mould, carried out with resin Embedding, specific method is as follows:
A, appropriate epoxy resin is injected into silica gel mould, the plant after processing is put into;
B, after first resin by injection 6-10 hours, epoxy resin is re-injected, plant is embedded completely;
Further, in step 7) in, at normal temperatures, the hardening of resin time is 12-24 hours.
Relative to prior art, beneficial effects of the present invention are:
Using the technical method of the present invention, the meat herbaceous plant form color being embedded in resin is true to nature, the mark of making This transparency is high, it is easy to which the details of observation of plant all directions, sample shape size is various, light to be readily transported and carry, and Resin does not turn yellow for a long time, and sample is anti-oxidant being capable of long Kubo color.Existing plant specimen preparation method is solved to be difficult to preserve meat The problem of matter herbaceous plant.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing skill The accompanying drawing used required in art description is briefly described, it should be apparent that, drawings in the following description are only the present invention Some embodiments, for those of ordinary skill in the art, on the premise of not paying creative work, can also basis These accompanying drawings obtain other accompanying drawings.
