Description
Technical field
The present invention relates to be used for the fetch earth device of earth sample of alkaline land, paddy field vertical section, dependent territory earth scientific domain.
Background technology
At present, the earth boring auger that paddy field season of growth soil sampling often adopts dry land to use fetches earth, and during operation the cast geotome is pierced the soil layer that needs the degree of depth.When taking out earth boring auger, upper water flows away, and remaining slowly drained soil is packed in the utensil, and this belongs to the commonplace method of sampling.More traditional then is to cut the earth with spade, because water is arranged, and the very difficulty that operates, and hinder seedling.When research paddy field saline-alkali soil salinity was dynamic, because leaching and evaporation, the variation vertical direction of salinity was more obvious in the saline-alkali soil; The salinity of vertical section alters a great deal; And dissimilar solonchak, the distribution of salinity in section is different again, so when sampling; Need take pedotheque in certain degree of depth (about general 1m, the darker 2m that reaches) layering.And in this case, when fetching earth with earth boring auger, because the soil below the topsoil does not stir for many years, soil is consolidation very, and the manually-operated intensity of getting up is big, dumb, and very effort is with time-consuming, moreover wet and slippery owing to soil, is easy to generate error.As use power drill, cost high (power drill and fuel oil) then.Take a sample then more infeasible in the paddy field with spade.
Summary of the invention
The objective of the invention is to above-mentioned deficiency, provide a kind of simple in structure, cost is low, easy to use, flexible operation, and is time saving and energy saving, and can use continuously, improves the paddy field salt affected soil sampling apparatus of data accuracy.
Described paddy field salt affected soil sampling apparatus comprises: cylindricality bucket, bung, rubber plug and metal drops thing, and on the cylindricality bucket, the distributing scale and the hole of fetching earth, the diameter in the hole of fetching earth is advisable to put earth boring auger into.
The present invention adopts following steps to achieve these goals:
1. material is prepared: according to the design soil sampling degree of depth, buy the toughened plastic bucket (subsidiary lid) of respective depth, its diameter is with the normal adult human of standing, and handled easily quarter butt earth boring auger is advisable.At bucket internal labeling scale, the scale size is set (like 10cm or 20cm) according to purpose.Near scale, each vertical scale centre position boring, the diameter in hole is advisable to put earth boring auger into.More multiple if desired multiple or make error minimize, can all punch in other three directions of bucket, it is subsequent use to prepare section and be trapezoidal rubber plug.
2. the field is arranged: before the soaked field, according to test design, dig pit in the relevant position, rice field, the degree of depth is advisable (certainly, different regions can according to later water irrigating depth and custom adjustment) with the sampling bucket 20cm that bassets, and diameter is advisable with smooth placement sampling bucket.After the sampling bucket embeds the hole, the rubber plug that step 1 is prepared is filled in the hole of fetching earth, press consolidation, leak in the bucket of back in case pour water in the paddy field.When raining, bung is covered, in case ponding in the bucket, bung will have the metal drops thing, in order to avoid bung is removed by external force such as wind.
3. soil sample: press design time, the sampling people carries the quarter butt earth boring auger and gets in the bucket, extracts rubber plug in the thieff hatch (noticing that the sampling back is the jam-pack rubber plug rapidly, in case get into dilutional hyponatremia in the bucket), and pedotheque is taked in layering.Ponding in the bucket of sampling back is scooped out with vessel.
Advantage of the present invention:
Saline-alkali soil vertical sampling device in paddy field of the present invention, simple in structure, the cost of material is low, be prone to obtain; Short earth boring auger sampling is simple and convenient in the bucket; The sampling bucket can be placed in the field for a long time to be continued to use, and reduces sampling error.
The present invention samples, and bucket can be applied in the paddy field season of growth and wetland soil is sampled, and can be used in the pedotheque collection of analyzing paddy field or the migration of wetland VG (vertical gradient) salt basic ion, the nutrient regularity of distribution, Root Distribution and microbial profile etc. specifically.Have simple in structure, cost is low, arrangement is convenient, sampling error is little, operator's easy master, advantages of wide application range have promotional value.
Description of drawings
Fig. 1 is the structural representation of a kind of paddy field of the present invention saline-alkali soil vertical sampling device, among the figure: 1 cylindricality bucket, 2 bungs, 3 metal drops things, 4 fetch earth hole, 5 rubber plugs.
Embodiment
The present invention is further described with the embodiment that provides below in conjunction with accompanying drawing.
With reference to Fig. 1, this device that is used for paddy field saline-alkali soil vertical sampling is made up of cylindricality bucket 1, bung 2, metal drops thing 3, fetch earth hole 4 and rubber plug 5.
Before the use, with bucket inwall reference mark, the scale size is set according to purpose, and the size in the hole of fetching earth will be according to quarter butt earth boring auger and the design of rubber plug diameter.
When inlaying, the device of vertical sampling is embedded in the sampling plot, mosaic point will select that physical features is smooth, the place of convenient turnover, preferably is chosen in to inlay the operation of conveniently digging pit before pouring water.The size in hole will be in strict accordance with the size of bucket, is floated easily after too big cylindricality bucket is inlayed, and the too for a short time difficulty of inlaying is big, also causes a barrel inwall deformation of unevenness easily, space and measuring accuracy in the influence bucket.The Kong Yaoyong rubber stopper seal that fetches earth is lived, and can not leave the space, in order to avoid water and earth infiltrate in the bucket.Bung will be built, and avoids rainwater and toy to get into, and metal drops thing weight should be not less than 2.5kg, avoids bung to be moved by external force such as wind.
During sampling, the sampling people will operation in bucket, will gently advance gently in the time of in the turnover bucket, avoids artificial outside destroy cylindricality bucket, when fetching earth one by one the hole point carry out, want rapid jam-pack rubber plug after extracting rubber plug and fetching earth.After finishing, sampling builds bung.
Designer of the present invention presses embodiment, uses the device of this paddy field saline-alkali soil vertical sampling, on rice terrace, uses; Show that through inner on probation uses very conveniently, the operator is easy to grasp; Speed and precision that the paddy field soil sample is gathered have been improved; Reduced sampling error, and with low cost, have promotional value.
