Description

Technical Field

[0001] The utility model relates to the technical field of forest ecosystem observation, in particular to a portable plant branch runoff collection device. Background Art

[0002] As one of the most basic parts of an ecosystem, water determines the growth and development of vegetation in the ecosystem. Vegetation redistributes rainfall through runoff, changing the hydrological process and spatial distribution pattern of precipitation in the ecosystem, regulating water balance, and helping to maintain soil erosion and reduce surface runoff. Plant branch runoff is one of the important observation indicators of ecohydrology, which helps to understand the regulation of local hydrological processes by vegetation in the region. It is of great significance for exploring the water balance of the ecosystem, the redistribution of forest precipitation, and investigating the suitable vegetation types in the region.

[0003] Generally, the observation of vegetation runoff is mainly the observation of tree runoff. The conventional observation method is to use a polyethylene rubber tube, cut it open and spirally wrap it around the tree trunk, fix the rubber tube with nails or stick it with asphalt, and connect a tipping bucket flowmeter at the bottom. In the case of long-term observation, the polyethylene rubber tube is easily affected by the temperature, and aging may even cause the water collection pipe to close; dead branches and fallen leaves are easy to block the water collection pipe; the fixing method is easy to damage the tree trunk tissue and cause adverse effects on the plant, affecting the observation effect of long-term vegetation runoff.

[0027] The present invention will be further described in detail below in conjunction with specific embodiments, which are intended to explain the present invention rather than to limit it.

[0028] The utility model discloses a portable plant branch runoff collection device, referring to Figure 1 A portable plant branch runoff collection device includes a collection structure 2, a first drainage pipe 3, a flow meter 4, a second drainage pipe 7, a collection bucket 5 and a filter 6.

[0029] The collecting structure 2 is sleeved on the outside of the plant branch 1, and its bottom is fixed on the plant branch 1 at an angle of 5° to 15°, so that the branch runoff can be collected at the upper end of the first drainage pipe 3. Figure 2 , 3 The collection structure 2 includes an inner telescopic layer 22 and an outer shell 23, wherein the inner telescopic layer 22 is closely attached to the outer side of the plant stem through the outer shell 23; wherein the inner telescopic layer 22 is a telescopic sealing clay layer, and the outer shell 23 is made of an extruded board and is fixed to the outer side of the inner telescopic layer 22 through a buckle structure 21. When installing, first unfold the runoff collection device to surround the main stem of the plant, requiring the telescopic sealing clay layer to be completely attached to the main stem of the plant, and buckle the buckle structure 21 until it does not shake and is fixed.

[0030] The bottom of the inner telescopic layer 22 and the outer shell 23 are inclined, and a drainage hole is opened at the lowest point to facilitate the branch runoff to be collected in the drainage hole. One end of the first drainage pipe 3 is connected to the inside of the outer shell 23 through the drainage hole, and the upper port is flush with the lower end of the sealing glue layer. The other end is connected to the water inlet end of the flow meter 4, and the water outlet end of the flow meter 4 is connected to the collection bucket 5 through the second drainage pipe 7. In this embodiment, the flow meter 4 adopts a K24 elliptical tooth flow meter 4 to accurately record the tiny flow, which is conducive to the recording of the runoff data of the plant branch 1 and the comparison of the runoff collected in the runoff collection device. The water inlet end of the first drainage pipe 3 is flush with the bottom of the inner telescopic layer 22, and the drainage pipe is fixed to the plant branch 1 through a detachable structure, such as a waterproof tape.
