Abstract

The invention provides a method and equipment system for in situ dynamic monitoring of a wetland plant root system and relates to the technical field of plant physiology and ecology engineering. The method includes steps of performing root system grading according to root system parameters obtained through digital processing of root system images of modeling wetland plants by root system analyzing software and obtaining a corresponding biomass model through curve fitting according to different grades of the root system parameters; performing root system grading according to root system parameters obtained through digital processing of root system images of to-be-tested wetland plants by the root system analyzing software and obtaining real time root system biomass by substituting the real time parameters into the biomass model of the corresponding grade. By adopting the method for model establishing and evaluating of biomass of plant root systems, shortcomings of poor continuity, damage to plants and complicated operation and the like of a conventional method can be overcome. The method provided by the invention is proved to have characteristics of being accurate, efficient, simple, convenient, being capable of realizing automatic and continuous monitoring and the like.

Description

technical field [0001] The invention relates to the technical field of plant physiological and ecological engineering, in particular to a method and an equipment system for in-situ dynamic monitoring of wetland plant roots. Background technique [0002] The root system is an important part of plants, which absorbs various nutrients for plant metabolism and plays an extremely important role in the process of plant growth and development. Therefore, the study of root physiology and ecology has become the focus of current research. Root growth status is the basis of root physiological and ecological characteristics, and in-depth and accurate continuous measurement and analysis of plant root growth characteristics and parameters is of great significance for in-depth understanding of root physiological processes and ecological functions. However, because the root system grows underground, there are certain difficulties in accurate sampling, measurement, and observation, and the ...
