Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of soil seed sampling, more specifically relates to a portable device of layered collection of aeolian sandy soil seed bank. BACKGROUND

[0002] Soil seed bank refers to the sum of all viable seeds present in the surface soil (including litter). Numerous research results show that the soil seed bank is the memory bank of the past plant community, and its characteristics can show the past plant community; at the same time, the soil seed bank is also the potential plant community, and its characteristics can predict the future plant community. Therefore, since the late 1980s, the soil seed bank has become one of the hotspots of plant ecology research.

[0003] The soil seed bank is the basis for the colonization, survival, reproduction and spread of plant populations, and is an important part of the response of plant communities to habitats, affecting the resistance and resilience of ecosystems, and playing an important role in vegetation occurrence and succession, regeneration and restoration. Desertification land management in arid areas is an important work that the world is working together to carry out, and plant measures are the most effective and long-term means of desertification land management. Proving the characteristics of the soil seed bank of desertification land can provide important basis for revealing the mechanism of vegetation degradation, succession and restoration in arid areas, and plays a crucial role in desertification land management.

[0004] For scientific research on soil seed bank, domestic and foreign scholars generally adopt the combination of field sampling and indoor germination experiment. Among them, different scholars use different tools according to different research purposes. For aeolian sandy soil in arid areas, due to its good sand material sorting, loose and not forming a group, strong fluidity, it is difficult to collect soil seed bank samples by layering. Researchers have developed many samplers for this phenomenon, but the sampling process is almost the same, that is, by pressing the sampler body into the soil, then digging one side, and finally using the insert plate to collect samples by layering. But from the current sampling process, most researchers designed the insert plate without handle, which is difficult to insert horizontally. Secondly, during the sampling process, the samples are collected from top to bottom layer by layer. Due to the gap between the insert plate and the sampler, the loss of the collected samples is large, and some small seeds will also be lost with the aeolian sandy soil.

[0005] Therefore, how to provide a portable device with simple structure, time and labor saving, and one-time collection of multi-layer samples into the sample bag is one of the technical problems to be solved in the field. UTILITY MODEL CONTENT
