Description

A kind of portable topsoil sampling thief
Technical field
The utility model relates to a kind of soil sampling appts, particularly a kind of portable topsoil sampling thief.
Background technology
The collection of pedotheque is the prerequisite that utilization of agricultural resources utilization and environmental science are analyzed soil nutrient and pollution degree evaluation, is be engaged in one of important element task of soil investigation work scientific worker.Whether the sample gathered is representative, directly affects accuracy and the precision of test analysis, is that can measurement result the important prerequisite condition of reflect soil environmental aspect strictly according to the facts.Carry out should first section being rebuild before soil sampling, cleaning, the surface dust on most top layer of pruning, and then press level and successively sample from center typical parts from bottom to top.
Think in pedology, upper soll layer soil generally refers to the soil layer that in soil, 0-200mm is thick, relatively complete owing to growing, the nutrient of veneer of soil and the content of organic matter the highest; Veneer of soil is also the interface of the soil body and environmental exposure simultaneously, carries from the various materials in environment.Research veneer of soil is significant for instructing crop-planting and disclosing soil pollution situation.
Soil sampler is the indispensable instrument being engaged in soil sampling work, uses soil sampler to be comparatively widely mainly divided into two large classes at present: a class is the earth boring auger that degree of specialization is higher, and another kind of is various spades.
When using earth boring auger as soil sampler, its sampling head vertically need be inserted in soil, extrude, rotate to certain depth of soil after earth boring auger is taken out, collect pedotheque in earth boring auger and treat subsequent analysis.Its advantage is: can carry out Vertical Sampling; Destroy little to the soil layer construction of soil in protected field, disturbance is few, decreases the injury to crop root.Its shortcoming existed has: level sampling is carried out in inconvenience, can not to the accurate layering of sample, and pedotheque profile features is difficult to differentiate; Sampling is wasted time and energy, and needs the sample in manual collection earth boring auger after sampling; The sample size of each collection is few, needs continuous acquisition repeatedly, inefficiency, is only applicable to the collection of a small amount of sample; In addition because its degree of specialization is higher, structure relative complex, parts are more, and O&M is comparatively inconvenient.
Spades, as the conventional tool of soil sampling, is usually used in the topsoil sample gathering farmland or wasteland.When gathering pedotheque, often need excavate heatable adobe sleeping platform near sampled point, then in the soil profile collected specimens of hole wall.Its advantage is: sample simple and easy to do, and speed is applicable to the collection of a large amount of sample; Conveniently carry out the level sampling of soil.Its shortcoming existed has: sample collection workload is relatively large; Vertical Sampling is carried out in inconvenience, and takes the mode of digging pit to destroy larger to the soil layer construction of soil in protected field and spacing in the rows is closer in kind of soil root system of plant; The collection of sample simultaneously often needs manual operation to complete.
In addition, due to the use limitation of existing soil sampler, soil collecting is all generally come by multiple different soil sampler, and easily cause sample room systematic error comparatively large, the accuracy of test analysis is affected.
Utility model content
The utility model, for the deficiency in existing sampling tool, provides a kind of portable topsoil sampling thief, and structure is simple, can carry out level sampling and Vertical Sampling respectively, and sampling amount is large, easy to use, laborsaving.
Technical solution adopted in the utility model is:
