Abstract

The invention provides a soil preferential flow zone simulation research device and method, namely a device and method for simulating soil pores to form a preferential flow zone by utilizing a water-soluble material polyvinyl alcohol 3D printing and analyzing the influence of different environmental conditions on microorganisms and soil organic matters in the preferential flow zone. The device is composed of an optical fiber oxygen meter control end, an optical fiber oxygen meter probe, a crotch-shaped pore, an inverted L-shaped pore, a cylindrical pore, an S-shaped pore, a water outlet, soil and organic glass. After a soil sample is collected, parameters such as abundance of microorganisms and molecular characteristics of soluble organic matters in soil are analyzed and measured by virtue of technologies such as high-throughput sequencing and Fourier transform ion cyclotron resonance mass spectrometry. By comparing the parameters, the influence of different environmental conditions on microorganisms and soil organic matters in the soil preferential flow area is analyzed. The device is advanced, is convenient to operate, and is not limited by the external environment.

Description

technical field [0001] This application belongs to the technical field of soil monitoring, and relates to a soil preferential flow area simulation research device and method, in particular to a preferential flow area based on water-soluble material polyvinyl alcohol 3D printing to simulate the formation of soil pores, so as to study the environmental impact caused by soil Apparatus and method for modification of microorganisms and soil organic matter in priority flow areas. Background technique [0002] In the context of globalization and industrialization, the impact of human production activities on the environment cannot be ignored. For example, due to the combustion of fossil fuels, vehicle exhaust and industrial waste gas emissions, sulfur dioxide and nitrogen oxides interact with water vapor in the air, eventually forming atmospheric acid deposition such as acid rain, which affects soil closely related to agricultural production activities. Soil preferential flow is a...
