Description

Novel annular sampling of soil is used in agricultural research device

Technical Field

The invention relates to the technical field of soil sampling, in particular to a novel annular sampling device for soil for agricultural research and development.

Background

Soil sampling refers to a method for collecting soil samples, and comprises sampling arrangement and sampling technology. The sampling of the soil sample in the cross section is performed after the cross section observation is completed. Before sampling, the section should be trimmed and cleaned, the most superficial layer of the floating soil is cut off, and then the sample is taken from the central typical part layer by layer from top to bottom according to the layers. For example, to determine the amount of a pesticide, the pesticide is collected prior to the year of application, or at the time of crop maturity, simultaneously with the plant sample. Due to different research purposes, different requirements are imposed on the collection of soil samples. Different samplers are selected according to different sampling analysis purposes. A surface soil sample of the farmland or wasteland is collected, a small-sized shovel can be used for researching general physical properties of the soil, such as soil volume weight, porosity, water holding property and the like, and a cutting ring can be used. Ordinary small-size soil sampling ware mostly is little shovel shape, and not only the sample is inconvenient, and application range is narrow moreover, can not take a sample to the different degree of depth moreover. Therefore, the soil sampler needs to be improved, and the sampler which is simple in structure and can sample deep soil is designed. Therefore, we propose a novel annular sampling device for agricultural development soil.
