Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] Such as figure 1 Shown, a kind of sapling root sampling tool comprises sampling pipe 1, is enclosed within the solid cylinder 2 of sampling pipe top, and runs through the crossbar 3 of solid cylinder and sampling pipe, and described sampling pipe bottom has continuous The protruding sharp part 6, the top of the solid cylinder is flush with the top of the sampling tube, and there is a round hole 4 at both ends of the outer side of the cross bar, which is used for connecting the pull cord.

[0020] In this embodiment, the outer surface of the cross bar has external threads, and a pair of nuts 5 for limiting the cross bar are threaded on the cross bar. When installing, the nuts are pressed against the outer surface of the sampling tube to lock the solid cylinder and the sampling Tube crossbar3.

[0021] In this embodiment, in or...

Abstract

The invention provides a sapling root sampling tool and a using method. The tool comprises a sampling tube, a solid cylinder sleeving the top of the sampling tube, and a cross rod which penetrates through the solid cylinder and the sampling pipe; a continuously raised sharp part is arranged at a bottom end of the sampling pipe along the circumferential direction; the top of the solid cylinder is level with the top of the sampling pipe, and two ends of an outer side of the cross rod are each provided with a round hole for connecting a pull rope. The sampling tool disclosed by the invention hasthe advantages that the structure is simple, the field use is convenient due to non-electric driving, the tool is convenient to carry and use, sapling root, rhizosphere soil and non-rhizosphere soil samples can be simultaneously taken, and the sampling efficiency and the sampling accuracy are effectively improved.

Description

technical field [0001] The invention relates to a sapling root sampling tool and a using method. Background technique [0002] The sampling method of analytical test samples may vary according to the analysis object. Among them, the representativeness of sampling is crucial, otherwise, completely wrong conclusions may be obtained. In the experimental research of saplings and seedlings, it is often necessary to take sapling roots and soil samples for chemical analysis at the same time, in order to fully understand the content levels of the measured components in the soil and roots and the changes in their operation. Compared with crops, the roots of saplings are large and deep, and the soil often needs to be dug open before they can be taken out. In this way, the sampling site (depth and range) of the soil is destroyed, and the sampling accuracy is affected. Considering the characteristics of field sampling, a relatively simple sampling tool is also needed, which is easy t...
