Description

Technical Field

[0001] The invention relates to the technical field of seed rain collection, and in particular to a seed rain collection device adaptable to various terrains. Background Art

[0002] Seed rain is the process of spreading sexual reproductive bodies (seeds or fruits) of plants. Seeds of different plant species in a specific area can be collected through seed rain collectors. Researchers can analyze seed yield, size, shape, quality and other characteristics to understand the reproductive investment strategy of plants. The composition and quantity changes of seed rain can reflect the dynamic changes of plant communities. Using seed rain collectors to collect data can observe the succession process of plant communities. Collectors can also help determine the distance and direction of seed dispersal. By setting up multiple seed rain collectors at different locations and comparing the types and quantities of seeds collected at different locations, we can understand how seeds are spread through media such as wind, animals, and water.

[0003] In the wild environment, the seed rain collector needs to have good stability to withstand the influence of natural factors such as wind and rain, and avoid being trampled and overturned by wild animals. For some researchers who need to collect seeds in different locations, portable seed rain collectors are more advantageous. At the same time, it is also necessary to avoid the collected seeds being eaten by birds or small animals, and a protective structure needs to be added to the collector. In addition, the current seed rain collection device is not very applicable to different terrains. It is distributed at different heights on different terrains. In multi-layer vegetation structures, such as where trees, shrubs and herbaceous plants coexist, seeds of high-rise vegetation may be missed because the collector is not high enough. If the collector is too high above the ground, it is easy to be trampled by wild animals and is also easily affected by natural factors such as wind. Summary of the invention

When used in terrain without vegetation on the surface such as sand, the telescopic component 2 shrinks and can be supported on the ground surface by the support part at the bottom of the support frame 1.
