Embodiment 1

[0029] Such as figure 1 , figure 2 As shown, the support column A2 and the support column B3 of this embodiment are both aluminum hollow cylinders with a diameter of 5 cm and a height of 10 cm, and the inner diameter of the support column A2 is greater than that of the support column B3, so that the support column B3 can be retracted to the support column A2. The mouth diameter of the lower end 1 cm of the support column A2 in this embodiment is tightened inwardly to fit the upper end of the support column B3. The limit device in this embodiment is the elastic protrusion 8 provided on the inner wall of the support column A2. The elastic protrusion 8 is divided into upper and lower parts, and the elastic protrusions 8 of the upper and lower parts are evenly distributed along the circumferential direction; the elastic protrusions 8 located at the lower part are close to the end of the lower end of the support column A2, and the elastic protrusions 8 located at the upper part a...

Embodiment 2

[0034] Such as image 3 and Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that the limiting device of this embodiment is an inner pleat formed by invading the support column A2, and the inner pleat is divided into a horizontal inner pleat 5 and a longitudinal inner pleat 6, the transverse The inner pleat 5 is close to the end of the lower end of the supporting column A2, and the longitudinal inner pleat 6 is located above the transverse inner pleat 5 . In this embodiment, two short transverse inner pleats 5 are arranged at 1 cm above the radially inward tightening part of the lower port of the supporting column A2, and two long longitudinal inner pleats 6 are arranged above the transverse inner pleats 5 to adjust The coincidence distance between support column B3 and support column A2. The rest are all the same as in Example 1.

Embodiment 3

[0036] The difference between this embodiment and Embodiment 1 is that the limiting device of this embodiment includes an elastic protrusion 8 provided on the inner wall of the support column A2 and an inner pleat formed by indenting the support column A2, and the elastic protrusion 8 is located on the inner pleat. above or below; the inner pleats can be the horizontal inner pleats or the longitudinal inner pleats in the second embodiment. The rest are all the same as in Example 1.

[0037] Working principle of the present invention is:

[0038]According to the type of the underlying surface of the monitoring system, adjust the set height of the support column B3 inserted below the ground 7, dig out the sand in the support column B3, install the seed rain capture plate 1 on the upper end of the support column A2, and connect the seed rain capture plate 1 and the support The post A2 combination is installed on the top of the support post B3, and then the sand and soil in the s...

Abstract

The invention relates to a sand seed rain trapper capable of adjusting the depth inserted into soil. A support column A and a support column B are inserted under the ground, a seed rain catching diskand the upper end of the support column A are connected in an inserted manner, the lower end of the support column A and the upper end of the support column B are connected in a manner of being capable of stretching out and drawing back relatively, the support column A is provided with a limiting device for adjusting an overlapping distance between the support column B and the support column A, and the support column B is inserted in from the lower end of the support column A and is then fixed by the limiting device under the ground by the required depth; and the top edge of the seed rain catching disk extends outwards to form an extension part, the outer edge of the extension part is bent downwards and then bent inwards to form a bending portion, a seed rain collecting bag is sleeved withthe seed rain catching disk, the support column A and the support column B, and the edge of the top of the seed rain collecting bag is arranged on the extension part and the bending portion in a sleeving manner and is fixed to the ground through the bending portion. The sand seed rain trapper has strong pertinence to the natural condition of a sand area, and can effectively improve the practicalvalue of vegetation restoration provenance monitoring work in the sand area.

Description

technical field [0001] The invention relates to a field vegetation research and monitoring device, in particular to a sand seed rain catcher which can adjust the depth of insertion into the soil. Background technique [0002] The vegetation restoration of sandy land in arid and semi-arid areas is an important ecological challenge faced by scientific researchers and relevant management departments. Plant seeds are the source of ecological restoration, and seed rain refers to the amount of seeds scattered from the plant mother plant at a specific time and specific space, which is a vivid description of the dispersion of plant propagules (seeds and fruits). It can be seen that seed rain is a key link in the life history stages of plant production from seed production to seedling colonization, and it is also a key link in vegetation restoration in sandy areas. Through the long-term monitoring of the seed rain diffusion pattern, the spatio-temporal pattern of the soil seed bank ...
