Embodiment Construction

[0015] Specific embodiments of the present invention will be described in detail with reference to the above-mentioned drawings. figure 1 , figure 2 and image 3 Combined with a sampling device for rhizosphere micro-domain soil, it includes a square box body 1, and two mesh-shaped segmented pieces 3 connected to the inner surface of the box body 1 without gaps are arranged symmetrically in the inner cavity of the box body 1. Thus, the inner cavity of the box body 1 is divided into a left chamber 5, a middle chamber 6 and a right chamber 7; the left chamber 5 and the right chamber 7 are symmetrically located on both sides of the middle chamber 6, and the mesh-shaped dividing sheet 3 is parallel to the center of the box body Line 4. The box body 1 is made of PVC board and is a detachable box body, that is, a movable box body that can be disassembled into a left chamber 5, a middle chamber 6 and a right chamber 7; Sampling operation at the end.

Abstract

The invention discloses a rhizosphere soil sampling device, comprising a square box, where two mesh dividing pieces seamlessly connected with the box are symmetrically arranged in the cavity of the box, so as to divide the cavity into left, middle and right chambers, the two mesh dividing pieces are parallel with the centre line of the box, at least a mesh insert piece is arranged in each of the left and right chambers, the mesh insert piece seamlessly adheres to the adjacent mesh dividing piece, and the mesh insert pieces in the left and right chambers are symmetrical to the center line of the box, the mesh diameters of the mesh dividing pieces and mesh insert pieces are all 25 microns. And the sampling device can implement sampling of rhizosphere soils at different mm levels.

Description

technical field [0001] The invention relates to a sampling device for rhizosphere micro-domain soil. Background technique [0002] The development of rhizosphere pollution chemistry largely relies on the differentiation of rhizosphere microsoils. For the collection method of rhizosphere soil in the conventional rhizosphere research method, the traditional research mostly uses the artificial shaking separation method and the root bag method. These two methods have the defect of inhomogeneous sampling volume under conditions such as different plant species, soil type and field humidity (Rillig et al., Soil Biology & Biochemistry 1997, 29: 1387~1394), and easily lead to a small number of root tissues especially Root hair residues, which affect the analysis and determination of rhizosphere soil microbial biomass (Mueller et al., Soil Biology & Biochemistry 1992, 24: 179-181), and cause researchers to be biased when evaluating the remediation effect of the tested plants on the t...
