Problems solved by technology

These methods generally have problems, mainly focusing on the damage to the root system in situ, large errors caused by man-made, or low precision.
At present, the method of in situ measuring the spatial structure of root system using CT scanning method has become the most cutting-edge method at home and abroad, but due to the limitation of scanning cost and sampling cost, this method has not been widely used
Internationally, although this method has been applied, the sampling method adopts the artificial mining method, which is more disturbing; the published articles in China mainly focus on the threshold segmentation of root system and three-dimensional visualization, mainly relying on the method of programming by relevant scholars processing, without a dedicated software and a set of unified data processing methods
In addition, the research on the root system in China has not yet realized the quantification of the spatial network structure of the plant root system; or it is limited to two-dimensional quantitative analysis; in terms of analysis software, it mainly relies on programming software or open source software such as Image J, professional three-dimensional software such as Avizo less use of

Abstract

The invention discloses a CT scanning technique-based quantification method of a root space net structure, comprising the following steps: sample acquisition, sample CT scanning, data enhancement, selection of threshold, image cutting and binaryzation, three-dimensional visualization and three-dimensional quantification. The invention has the following beneficial effects: by the use of a specialized sampling instrument for sampling, the disturbance on root in situ is reduced; and by combining a CT scanning instrument and a specialized three-dimensional analysis software and by the most appropriate threshold segmentation method, three-dimensional quantitative analysis of the plant root space structure is realized.

Description

technical field [0001] The invention belongs to the technical field of agricultural engineering, and in particular relates to a method for quantifying root space network structure based on CT scanning technology. Background technique [0002] The traditional methods for determining the root system mainly include nail plate method, container method, glass wall and glass tube method, isotope measurement method, porous membrane technology method, root washing method combined with WinRHIZO software, and the current non-destructive testing method ground penetrating radar method. These methods generally have problems, mainly focusing on the damage to the root system in situ, large errors caused by man-made, or low precision. At present, the method of in situ measuring the spatial structure of root system using CT scanning method has become the most cutting-edge method at home and abroad, but due to the limitation of scanning cost and sampling cost, this method has not been widely ...
