Description

A kind of separation method of middle-size and small-size dry, the wet animal of soil
Technical field
The present invention relates to soil animal separation method fields, and in particular to a kind of separation of middle-size and small-size dry, the wet animal of soil Method.
Background technique
Soil animal is the important biomolecule component part in soil ecosystem in addition to edaphon, and soil animal exists There are important ecological functions in soil, including promote plant root growth, soil nutrient circulation is participated in, in occupation of soil food Critical positions in chain can adjust soil microflora etc..It is especially right according to soil animal to the preference of Soil Habitat Soil animal can be divided into stemness and moist soil animal by the difference of the dominant population in soil different humidity environment.Stemness soil Earth animal, which refers to, accounts for main advantageous group in the lower soil environment of soil moisture, mainly include acarid class and springtail class Deng；Moist soil animal occupies the group of more advantage in the higher environment of soil moisture, mainly includes nematode, enchytrae and snail Worm etc..Generally directed to both different types of soil animals, traditional soil animal separation method is dynamic for soil humidogene Object uses the wet funnel method of Baermann, and the separation for dry raw soil animal then uses the dry funnel method of Tullgren.Two methods Two different separators are corresponded to.So when being separated at the same time to soil hygrocole and dry animal, because to adopt With two different device and method, the reduction of test efficiency will cause during the test, and for same soil-like When being separated, using different separators, the difference that may cause separation microenvironment causes different separative efficiencies.In order to Improve the inefficient and possible experimental error of both the above separation method, it is middle-size and small-size dry, wet dynamic that the present invention provides a kind of soil The separation method of object, and identical separation microenvironment can be reached for two different soil animals, it is more connect to realize Close separative efficiency.
Summary of the invention
In view of the above problems, the invention proposes a kind of separation methods of middle-size and small-size dry, the wet animal of soil.
In order to achieve the above purpose, the following technical solution is employed by the present invention:
A kind of separation method of middle-size and small-size dry, the wet animal of soil, method includes the following steps:
(1) choosing vegetable mould is sampling area, and randomly selects sampled point in vegetable mould sampling area；
(2) the deadwood leaf at sampled point is first collected, in the 2-6cm thickness vegetable mould for taking sampling to point out together with fallen leaves one And it is packed into cloth bag, sample is used for qualitative survey；
(3) the shoveling earth vertical section at sampled point, it is 100cm that capacity is squeezed on vertical section3Round soil sample Device digs out sampler since lowest level one by one, and the vegetable mould in each sampler is respectively charged into collection bag, is taken back Laboratory is used for quantitative interview；
(4) the vegetable mould sample of acquisition back is placed in the iron sheet funnel and glass funnel that upper layer is equipped with metal mesh In, soil animal collector is connect under iron sheet funnel and glass funnel, iron sheet funnel is contained for separating to terminate under dry raw soil animal There is vial, for separating humidogene soil animal, the front layer for putting pedotheque should be laid with aperture in funnel bottom and be glass funnel The double gauze of 2mm, wherein the pedotheque in glass funnel creates separating pathway using originally water submerged for hygrocole, Hose is terminated under funnel, and in its lower end clamp, it is dynamic to carry out soil in the case where power is the irradiation of 20-40W incandescent lamp Object separation, incandescent lamp is apart from vegetable mould upper epidermis 20-25cm spacing, from after incandescent light irradiation, after a period of time, collects soil Animal sample；
(5) the dry raw soil animal in vial is collected, nothing is added in the vial of Xiang Shengyou humidogene soil animal sample Water-ethanol makes solution concentration reach 65-80%, in case carrying out sorting, counting and the identification of soil animal, while measuring fertile soil The water content of earth sample.
Preferably, the water content that the vegetable mould of sampling area is chosen in the step (1) is sampled for 50-80% adopts Collection.
Preferably, the round soil sample collector quantity in the step (3) is 5-7.
Preferably, iron sheet funnel is for separating dry raw soil animal in the step (4), and glass funnel is for separating humidogene Soil animal.
Preferably, the soil animal in vial is collected in the step (4) after 40-50h.
Preferably, it is 75% ethyl alcohol that addition ethanol solution, which is volume fraction, in step (5) vial.
Due to using above-mentioned technical solution, the beneficial effects of the present invention are: the present invention can effectively avoid the prior art The poor efficiency of separation method and there are problems that experimental error, method of the invention is by using iron sheet funnel and glass funnel point From soil animal, not only good separating effect, speed are fast, and it is micro- to reach identical separation for two different soil animals Environment, to realize the separative efficiency being closer to；Method of the invention grasp easy to operate, and good separating effect, be suitable for pair The separation of middle-size and small-size dry, the wet animal of soil.
