Crop root growth detection system and detection method

Abstract

The invention belongs to the technical field of crop growth detection, and particularly relates to a crop root growth detection system and detection method. According to the crop root growth detection system and detection method provided by the embodiment, the diameter is small, and a detection pipeline can be made thinner, so that influence on normal growth of crop roots is greatly reduced by using a detection head based on light-guide fiber; besides, the detection pipeline is set to be bent pipe or other shapes, multi-point and multi-period root growth and shape monitoring in soil as well as detection of root growth at any position can be carried out, so that the degree of spatial freedom of crop root growth detection is greatly improved, and a new method is provided for in-situ growth and shape detection of the crop roots.

Description

technical field [0001] The invention relates to the technical field of crop growth detection, in particular to a crop root growth detection system and detection method. Background technique [0002] As the link between crops and soil, the root system plays a vital role in the execution of its functions. Root growth and architecture reflect the adaptability of crops to the soil environment, which is also the basic way and the most direct channel for humans to understand, analyze and evaluate the adaptability of crops and soil. Since the root system is an important part of the plant that cannot be ignored, and compared to the aboveground part of the plant, the medium of root growth—soil is opaque, making it difficult to directly observe the data of the root system. The equipment focuses on the data acquisition method and equipment of the root system. [0003] The data acquisition of crop root system is mainly divided into two categories, one is destructive data acquisition, ...

Problems solved by technology

[0005] Although the destructive root system data acquisition method can obtain the topological information of the crop root system and the two-dimensional root system morphological parameters, etc., it destroys the in-situ information of the crop root system and cannot observe the growth of the root system

[0006] Among the in-situ detection methods, the ground penetrating radar method is only good for tree roots, and has poor imaging effects for relatively thin crop roots; although the special environment cultivation method can observe the continuous growth process of crop roots, it cannot reflect the crop roots. The actual growth status in the soil; the CCD camera method is only suitable for in-situ data acquisition in the absence of soil in space; the penetrating radiography method requires expensive equipment and cannot perform data acquisition of the root system environment in large soil

[0007] In the method of installing observation devices in the soil, the root box method is to bury an observation room at the position where the roots will grow before planting crops, and place a scanner or camera in it for continuous root growth and shape data acquisition. It can only obtain a section information of the root growth environment, and has a great interference effect on the growth of the root system reaching this section; the micro-root canal method is currently one of the most commonly used methods for monitoring the dynamic growth of the root system in the field. Embed micro-root canals at the root growth position, and place a rotating scanning device in the micro-root canals during the root growth period to scan the roots. However, due to the relatively large diameter of the micro-root canals, embedding too many micro-root canals will also affect the growth of crop roots. The natural growth state, and the micro-root canal must be a straight pipe to be placed in the root scanner for root data acquisition, but this also greatly limits the spatial freedom of root data acquisition
