Description

Technical Field

[0001] The utility model relates to an agricultural ecology experiment, in particular to a rain shielding device for an agricultural ecology experiment. Background Art

[0002] Agricultural ecology is a branch of applied ecology. It mainly uses the principles and methods of ecology and systems theory to treat agricultural organisms and their natural environment as a whole, studying their interactions, co-evolution, and the laws of regulation and control of the socio-economic environment, in order to promote the comprehensive and sustainable development of agriculture. It is a discipline based on the principles and concepts of applied ecology that studies the relationship between human agricultural activities and their environment.

[0003] In the study of agricultural ecology, there are many experiments that require rain shelter devices, such as: determination of soil carbon flux, determination of soil carbon storage, determination of soil physical and chemical properties and microbial characteristics, simulation experiment of soil erosion on slopes, determination of water consumption of agricultural ecosystems, determination of soil moisture balance, etc. In these experiments, in order to facilitate rain shelter, rain shelter facilities are usually built with tarpaulins and ropes. This method has poor stability and is easily blown over by strong winds. At the same time, under the action of strong winds, rainwater will enter from the sides of the tarpaulin, making it impossible for the tarpaulin to play a rain shelter effect and affecting the accuracy of the experiment.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
