Fig. 1 is the structural representation of experimental provision provided by the invention.
Fig. 2 is the exploded view of the division board of experimental provision provided by the invention.
Each mark is as follows among the figure: 1 cylinder, 2 division boards, 3 drain bars, 4 geotextiles, 5 manholes, 6 basins.
Embodiment
The present invention will be further described below in conjunction with accompanying drawing, but invention is not limited to following examples.
Experimental provision for the research of root system subregion provided by the invention comprises the cylinder 1 of upper and lower opening, the internal diameter unanimity of this cylinder 1, and it is made by lucite; Be provided with a division board that is mated 2 in the cavity of this cylinder 1, this division board 2 is parallel with the end face of cylinder 1, and 1/4 height (40cm height) that is positioned at this cylinder 1 locates, and cylinder 1 is divided into two Room up and down; This division board 2 is made up of drain bar 3 and the geotextiles 4 be located on the convex surface end of this drain bar 3, thereby reaches root resistance but the purpose that do not block water; The center of this division board 2 is provided with a manhole 5, and its internal diameter can be regulated according to the plant root growth situation; This device comprises a basin 6, and it is 30cm highly, and it is made by lucite, and cylinder 1 can place in this basin 6.
In the above-mentioned experimental provision, cylinder 1 and basin 6 all also can be made by PVC; But the internal diameter of cylinder 1 increases from an end face to the other end foundry goods; The internal diameter of manhole 5 can be adjusted in the scope of 2～20cm according to actual needs; The position of division board 2 can be according to actual needs adjusted at the height place of 20～80cm of cylindrical shell 1; The height of basin 6 can be adjusted in the scope of 20～40cm according to actual conditions.
When using above-mentioned experimental provision, generally in rain-proof shelter, put basin 6 at first selected experiment place by the experimental design position, and the experiment of packing into is with soil, and is real with depositing in water; Cylinder 1 is placed the basin 6 that installs experiment usefulness soil, in cylinder 1, pack experiment into native, can imbed all kinds of probes at arbitrary height according to the experiment needs and be used for indexs such as monitoring soil temperature, humidity, soil water potential, when treating that soil thickness reaches the height of experiment needs, division board 2 is put into; The plantling root system lateral root that size is consistent is relatively wiped out, and the part main root is imbedded in the soil under the division board 2, and main root remainder height should be lower slightly with the residual altitude of cylinder 1; The continuation experiment of packing in the cylinder 1 reaches the plant stem base portion with soil.
