Problems solved by technology

However, these observation systems and software are complex to install, cumbersome to operate, and have certain difficulties in analyzing the entire three-dimensional configuration of plants. Advanced image acquisition technology, to a certain extent, the root canal will hinder the growth and extension direction of the root system, and the same root system must be searched every time the image is collected, which limits the accuracy of observation

Abstract

The invention relates to a test device and method used for researching a root system three-dimensional architecture. The device comprises a distance determining device and an image collecting device. The distance determining device is used for adjusting the shooting distance and the angle of a plant root system and comprises a guiding ruler with scales and a distance determining rotating platform fixed to one end of the guiding ruler with the scales. The distance determining rotating platform comprises a movable rotating disc which rotates around one end of the guiding ruler with the scales, and a plant placing table is arranged on the movable rotating disc, wherein a plant needing root system observation is placed on the plant placing table. The image collecting device comprises a shooting platform, a digital single-lens reflex camera and a distortionless camera lens, wherein the shooting platform can axially slide relative to the guiding ruler with the scales, and the digital single-lens reflex camera is arranged on the shooting platform. A lens of the digital single-lens reflex camera faces the plant in the guiding direction of the guiding ruler with the scales, and the distortionless camera lens is arranged in front of the lens of the digital single-lens reflex camera. The device and method can accurately obtain a high-resolution image of the root system which is already taken out or the water planting seedling root system in a glass container, and therefore the accurate root system three-dimension architecture is obtained.

Description

technical field [0001] The invention belongs to the research field of root system three-dimensional configuration observation technology, and mainly relates to the research on the spatial distribution characteristics of plant roots in soil, in particular to a test device and method for researching root system three-dimensional configuration. Background technique [0002] Plant root architecture is a comprehensive concept that describes the shape, structure and spatial distribution characteristics of roots in soil, and is an important factor that determines the distribution of plant roots and the efficiency of foraging for soil. With the deepening of scientific research, scholars at home and abroad have conducted a lot of research on the observation of the three-dimensional configuration of the root system. A major problem of research. [0003] At present, the observation methods of root system configuration mainly include image analysis systems such as CID and EI-100 in the...
