[0035] When it is necessary to collect plant litter samples, first, the bottom U-shaped supporting piece 4 is inserted into the mounting hole 6 through the mounting block 7, then the top of the supporting rod 2 passes through the penetrating hole 102, and then the top U-shaped limiting piece 5 is inserted into the mounting hole 6 through the mounting block 7, at this time, the bottom U-shaped supporting piece 4 provides support for the fixed ring 101 and the blocking fabric 1, and the top U-shaped limiting piece 5 limits the upward movement of the fixed ring 101 and the blocking fabric 1.

[0036] The fixed rod 11 is inserted into the fixed hole 9, and the threaded column 10 is threadedly connected with the threaded hole 8, at this time, the fixed rod 11 passes through the mounting block 7, and the bottom U-shaped supporting piece 4 and the top U-shaped limiting piece 5 are fixed.

[0037] Then the blocking fabric 1 is unfolded below the plant, the pre-buried rod 3 is buried underground, the support of the supporting rod 2 and the blocking fabric 1 is realized, at this time, when the leaves or branches of the upper plant and the like fall as litter, the litter can directly fall onto the upper blocking fabric 1, and finally the litter collection is carried out above the blocking fabric 1.

[0038] Conversely, after the litter collection is completed, the control knob 12 is rotated, the threaded column 10 and the threaded hole 8 are separated, the fixed rod 11 is pulled out upward, the bottom U-shaped supporting piece 4 and the top U-shaped limiting piece 5 can be removed, the supporting rod 2 and the blocking fabric 1 are separated, and the carrying and transportation of the device are facilitated.

[0039] Compared with the related art, the plant litter sample collecting device has the following beneficial effects:

[0040] The utility model discloses a blocking fabric 1 is fixed through support rod 2 below the plant of required collection litter sample, makes the blade or branch of plant etc. as litter falls, can directly fall to the top of blocking fabric 1, finally collects the plant litter of blocking fabric 1 top as sample, can avoid the litter sample of plant that is collected mixes in the litter of non - target plant, dust, insect excrement or gnawing of rodent bites produces the interference, and then leads to the sample that is collected is not pure.

[0041] The basic principle, main features and advantages of the utility model are shown and described above. Those skilled in the art should understand that the utility model is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principle of the utility model. Without departing from the spirit and scope of the utility model, various changes and improvements can be made to the utility model, and these changes and improvements fall within the scope of the claimed utility model.
