The open Simple potted plant device for dry crops of patent documentation CN201742761U, upper basin and lower basin be plastics, pottery, porcelain or The basin alms bowl that other waterproof material is made, is provided with bottom drain holes in the bottom of upper basin；The bottom lock of lower basin, at lower basin sidewall Basin bottom, at height 5cm at the bottom of basin, at height 10cm at the bottom of basin, three positions have sidewall osculum, and sidewall osculum is arranged by sidewall Water pipe is derived, and is connected to soft rubber pipe on sidewall drain pipe, and the folding of rubber tube is by clip control；Upper basin is placed in lower basin, The base diameter of lower basin is bigger than the base diameter of upper basin.

Species sensitivity for ease of heavy metal in soil is distributed the management of a large amount of pot experiments in research, reaches more preferable Test effect, this application provides a kind of species sensitivity distribution method different from above three patent documentation disclosure real Testing reaction unit, its structure and principle are relatively big with above-mentioned application difference, and above-mentioned application does not affect the novelty of the application.

Utility model content

The purpose of this utility model be for pot experiment in species sensitivity distribution method research process relate to several species, The situation of multiprocessing, by improving further existing Simple potted plant assay device, it is provided that one is easy to manage, can be optionally combined, Each process is reusable, can discharge the species sensitivity distribution method experiment reaction unit preserving soil sample for a long time.

The design that this utility model is used is:

A kind of species sensitivity distribution method experiment reaction unit, including testing stand, firm banking and proof box, in test Platform upper surface places firm banking, and base is gone into battle and shown multiple square draw-in groove, and setting-in proof box in draw-in groove, in the middle of each proof box Every being vertically arranged two dividing plates, three tests forming interval cut off, and are shaped with on each lower ground cutting off corresponding proof box End apopore, is shaped with a side apopore at each proof box sidewall cutting off correspondence, and the height of side apopore is less than dividing plate Highly, side apopore external connection side outlet conduit；The firm banking that three apopores of each proof box are corresponding is made There is water-guiding hole, firm banking is also shaped with side outlet conduit through hole, for through side outlet conduit, described testing stand upper surface Middle part is shaped with a plurality of water-flowing trough, and water-flowing trough converges to the limbers that middle part is shaped with, and limbers connects a drainage pipeline, drainage pipeline A water tank is accessed in end.

And, the upper cap of described proof box is equipped with upper cover.Advantage of the present utility model and good effect be:

Same box house is divided into by the species sensitivity distribution method experiment reaction unit that 1, this utility model provides Three parts, carrying out of three parallel tests of being more convenient for, reduce and take up an area, meanwhile, the upper limit drain pipe on bottom discharge pipe and top, It is easy to collect excessive moisture, it is to avoid the soil through Pollutant Treatment used by experiment produces two because watering water excess seepage to environment Secondary pollution.

12 casees can be placed in the base frames of the species sensitivity distribution method experiment reaction unit that 2, this utility model provides Body, meets the requirement to multiple species of the species sensitivity distribution method, the unified management of convenient experiment, guarantee test condition as far as possible Concordance, reduce test error, and reaction chamber can be optionally combined, different disposal is reusable.
