Abstract

The utility model provides a soil seed bank geotome includes the sampler connecting rod, fetch earth core and shell, fetches earth the fixed dress of joining in marriage of core at the lower extreme of connecting rod, and the dress is joined in marriage in the outside of fetching earth the core to the shell. The upper end of connecting rod is fixed and is joined in marriage the dress handle, and the surface of handle sets up anti -skidding line. The core that fetches earth is the heliciform, and the shell is the cylinder structure, the center and the fixed welding of connecting rod of the core that fetches earth, the outside of the core that fetches earth and the fixed welding of the inner wall of shell. The utility model discloses the structure is comparatively simple, but when fetching earth the earth sample in the field, because traditional sampler does not have the casting function, results in the sample collection inefficiency, and the sample layering of adopting is mixed manyly etc. Adopts the utility model discloses the process that fetches earth of carrying out open -air soil seed bank is swift, accurate, has improved the reliability of the data and precision in the experimentation, has reduced the emergence of the condition such as soil doping.

Description

Soil seed bank, soil seed pool soil sampler

Technical field:

This utility model relates to the technical field that fetches earth of soil seed bank, soil seed pool, is specifically designed a kind of soil seed bank, soil seed pool soil sampler fetched earth for field soil.

Background technology:

Soil seed bank, soil seed pool is the natural gene storehouse of plant population, the material base of natural renovation；Desert ecosystem is the ecosystem of most fragile on the earth.Therefore, soil seed bank, soil seed pool is rebuild at desert ecosystem and plays vital effect in recovery process.The research of Soil Seed Bank in Desert Region in recent years receives significant attention.Test by the research to desert steppe soil seed bank feature (size, density and dynamic), seed bank spatial and temporal distributions and seed bank with aboveground vegetation similarity, disclose the vegetation succession rule of desert steppe；In terms of Reproduction Strategies, by vegetational type's feature, species diversity and dominance, the research of breeding distribution, disclose plant to the adaptation ability of environment and reproductive potential, thus the ecological reconstruction for desert steppe provides scientific basis.Result of study will assist in people and understanding on the basis of desert steppe ecosystem succession rule, and giving treatment in accordance with the tendency of pathological change takes some artificial ancillary methods, utilizes indigenous plant to recover impaired ecosystem, it is ensured that the ecological safety of Desert Grassland.Fetching earth of soil seed bank, soil seed pool is most important, and traditional sampler does not has casting function, causes sample collecting efficiency low, more than the sample layering doping adopted etc..

Summary of the invention:

In view of this, it is necessary to a kind of soil seed bank, soil seed pool soil sampler is provided.

A kind of soil seed bank, soil seed pool soil sampler, including sampler connecting rod, fetch earth core and shell, and the lower end being fitted in connecting rod fixed by the core that fetches earth, and shell is fitted in the outside of the core that fetches earth；The fixing equipped handle in the upper end of connecting rod, the surface configuration anti-slip veins of handle；The core that fetches earth is helical form, and shell is cylindrical structure, and the center of the core that fetches earth is fixing with connecting rod welds, and the outside of the core that fetches earth is fixing with the inwall of shell welds.

This utility model structure is relatively simple, but when taking pedotheque in the wild, because traditional sampler does not has casting function, cause sample collecting efficiency low, more than the sample layering doping adopted etc., use this utility model to carry out the polyvinyl chloride fetched earth, precisely of field soil seed bank, improve reliability and the precision of data in experimentation, reduce the generation of the situations such as soil doping.

Accompanying drawing illustrates:

Fig. 1 is the structural representation of soil seed bank, soil seed pool soil sampler.

In figure: sampler connecting rod 1, the core 2 that fetches earth, shell 3, handle 4.

Detailed description of the invention:

Referring to Fig. 1, soil seed bank, soil seed pool soil sampler includes sampler connecting rod 1, fetch earth core 2 and shell 3, and the fixing lower end being fitted in connecting rod 1 of core 2 of fetching earth, shell 3 is fitted in the outside of the core 2 that fetches earth.The fixing equipped handle 4 in the upper end of connecting rod 1, the surface configuration anti-slip veins of handle 4.

The core 2 that fetches earth is helical form, and shell 3 is cylindrical structure, and the center of the core 2 that fetches earth is fixing with connecting rod 1 welds, and the outside of the core 2 that fetches earth is fixing with the inwall of shell 3 welds.Shell 3 and the core 2 that fetches earth are for welded upper and lower without top design.

Claims

1. a soil seed bank, soil seed pool soil sampler, it is characterised in that: soil seed bank, soil seed pool soil sampler includes sampler connecting rod, fetch earth core and shell, and the lower end being fitted in connecting rod fixed by the core that fetches earth, and shell is fitted in the outside of the core that fetches earth；The fixing equipped handle in the upper end of connecting rod, the surface configuration anti-slip veins of handle；The core that fetches earth is helical form, and shell is cylindrical structure, and the center of the core that fetches earth is fixing with connecting rod welds, and the outside of the core that fetches earth is fixing with the inwall of shell welds.
