Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1 to 3 of the drawings, a portable apparatus for measuring vegetation cover and yield of grasslands according to an embodiment of the present utility model comprises: the number of the connecting pipes 1 is four, the four connecting pipes are equal in length and are 1m, and the length dimension of the connecting pipes can be actually selected, preferably the whole dimension, so that sample square grids can be formed conveniently; a plurality of threading holes 2 are respectively arranged on the four connecting pipes 1 at intervals corresponding to the axial directions of the four connecting pipes;

the four quick connectors 3 are arranged, and the four quick connectors 3 are sequentially detachably connected with the four connecting pipes 1 at intervals to form a square frame structure;

the first threading rope 4 is sequentially and continuously connected with threading holes 2 on connecting pipes at two sides of the square frame structure to form nine transverse grid lines;

the second threading rope 5 is connected with the threading holes 2 of the upper connecting pipe and the lower connecting pipe of the square frame structure to form nine vertical lines; the transverse grid lines and the vertical grid lines are arranged in a crossing way, and 100 sample grids with the same specification are formed by matching with the square frame structure. The two threading ropes are convenient to carry on one hand and convenient to sequentially and continuously perforate on the other hand.

In other embodiments, 9 threading holes 2 on the connection tube 1 are equidistant.

In other embodiments, the connecting tube 1 is a PVC hollow tube, and the threading holes 2 penetrate through two side walls of the connecting tube.

In other embodiments, the quick connector 3 is a right-angle pipe sleeve, and the right-angle pipe sleeve is quickly spliced with the ends of two adjacent connecting pipes 1.

When the sample box is used, the connecting pipe and the quick connector are taken out and quickly assembled into a box structure, and then the first threading rope and the second threading rope are used for threading the sample box in sequence. The method is suitable for measuring vegetation coverage by using a needling method, and the measurement data is accurate. Is extremely light and portable, can be assembled on site, and the device can be disassembled after the work is finished, does not occupy volume and has light weight. The vegetation coverage is easy and clear to judge

The needling method is more accurate, and the specific cooperation of the device is as follows: the square frame structure (if the sample square frame is 1 x 1 m) is divided into 100 sample square frames with equal size and 0.1 x 0.1m by means of the first threading rope and the second threading rope, a thin needle (about 2 mm) is used for perpendicularly downwards needling from the upper part of vegetation in each sample square frame (each sample square frame follows the principle of not punching left and right and punching upwards and downwards, and needling is preferably selected at the intersecting point or the exact center position of each square frame so as to ensure objective rationality of sampling), and if the needle is contacted with plants, the needle is marked as 'having' once ', and if not contacted, the needle is marked as' not. And finally, calculating the number of times of occurrence of 'presence', wherein the number of times is expressed as the coverage by the percentage. For example: the fine needles are used for piercing each square sequentially, the plants in each piercing are marked as 'having', 100 square piercing is carried out for 100 times, after the needling is finished, the times of the plants in the piercing are counted, if the plants in the piercing are 90 times, the vegetation coverage in the sample square frame is 90%. The vegetation cover data is measured more accurately than by visual inspection.
