Description
Technical field
This invention belongs to ecological study fields such as pedology, environmental science, is applicable to the technical field of gathering deep soil section sample.
Background technology
Soil all has very important research status in a plurality of ambits such as pedology, environmental science, geology, ground, ecology, carry out the pedotheque of science according to experiment purpose and gather most important.In the pedotheque gatherer process, the researcher attempts to keep the original state of soil as far as possible, and wishes that the deep layer section of soil is had more understanding.All comprise research in many soil investigations, in to the deep subsoil sample collecting, how to reduce the interference of pedotheque and to reduce the excavation of earthwork amount as much as possible and obtain the deep soil sample be puzzlement researcher problem for a long time the deep soil sample.
In deep subsoil sample collecting process in the past, the acquisition methods that adopt destructive excavation more, plan to gather the pedotheque of 1～1.5m degree of depth as the researcher, it can only excavate the dark heatable adobe sleeping platform of 1～1.5m in the soil collection point, then the hole wall soil profile on collected specimens, time-consuming, the effort of this method, and serious destruction soil.In addition, the soil that many plasticity are bad, being difficult to excavate as ecosystems such as sand ground, wetlands is the soil profile that is shaped, for research brings a lot of inconvenience.The tradition soil sample collector often has a lot of shortcomings:
1, traditional soil sample collector mostly is airtight or semi-closed system, and sampler is squeezed into or extracted in the process of soil, because the distortion and the extruding of sampler, causes the breaking of soil layer, deflation, compacting easily, and the state of disturbed soil has influenced the authenticity of sampling;
2, adopt common sampler sampling, can only gather the pedotheque on top layer mostly, can't gather the deep subsoil sample in position;
3, the amount of fetching earth is low, can't satisfy the Test Application of a plurality of indexs;
4, when gathering the deep soil sample, a large amount of destruction soil, deep-cut heatable adobe sleeping platform, just can obtain pedotheque, time-consuming, effort, destructive big;
5, traditional soil collector can't be to the collection of carrying out deep layer section of pedotheques such as sand ground, mud ground and wetland.
Summary of the invention
The invention provides a kind of sample collecting device that can be applicable to polytype soil, can have in the soil original position and can reach the soil profile deep layer, disturbance to soil is very little, can obtain a large amount of soil samples, can be quantitatively, take the altitude gathers pedotheque, characteristics such as the easy disengaging of soil and sampling apparatus.
