Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of forestry, in particular to a decomposition simulation device for camphor tree fallen leaves. Background Art
[0002] The camphor leaf litter decomposition simulation device is a device used to study the decomposition process of camphor leaf litter, which helps us to have a deeper understanding of the mechanism of leaf litter decomposition, influencing factors and its role in the ecosystem. In the simulation of leaf litter decomposition, common methods include field experiments and indoor experiments. Field experiments, such as the net bag method, use net bags with different mesh sizes to limit the entry of soil animals of different sizes, so as to observe the decomposition effects of different organisms on leaf litter. Indoor experiments, by controlling temperature and humidity conditions, use methods such as sterilization-inoculation methods to observe the decomposition of leaf litter by organisms such as microorganisms and nematodes.
[0003] The purpose of conducting a simulated decomposition experiment of fallen leaves in the wild is to study the decomposition process of fallen leaves in the natural environment and its influencing factors. However, the existing simulation device for decomposing fallen leaves of camphor trees is generally not suitable for use in the wild. When simulating the decomposition process in the wild, the litter holding basket is generally fixed on the plant as described in patent CN218067836U, and then the fallen leaves on the trunk and branches are collected. After the placement is completed, a few leaves are taken for testing according to a preset time, such as a week, to observe their decomposition. However, such a structural stability is poor and is greatly affected by bad weather. It is also not convenient to fix the litter holding basket on the plant, and it is difficult to comprehensively collect fallen leaves from all positions of the camphor tree. At the same time, the decomposition simulation measures of the existing device are relatively single, and its litter holding basket is suspended, which is difficult to simulate the decomposition process of fallen leaves of camphor trees in a real natural environment.
