The development of functional genomics and genetic technology in the field of crop breeding is the most convenient and effective means for increasing the yield of grains. Phenotype is the external expression of a crop gene, and is the result of the co-action of the crop's own gene and the external environment. Therefore, it becomes important to explore the relationship between crop genotypes, environmental factors and crop phenotypic characteristics and traits.
The plant root system is an important component of the plant and has very important functions, such as absorption and transportation of water and nutrients, storage of organic matters, plant anchoring, interaction with soil and the like. The development condition of the plant root system is important for research work of a plurality of plants, and is related to a series of processes such as selection of optimal treatment time of the plants, consistency of growth and development states of the plants before treatment, and timely feedback of response of the plant root system in the treatment process. Due to the restriction of soil unobservability, the collection and analysis of root phenotypic traits become the key and difficult points of biological and phenotypic omics research.

The existing root phenotype acquisition technology becomes a bottleneck for restricting the functional analysis of plant genomes and the development of molecular breeding. With the rapid development of plant genomics research and molecular breeding, a root phenotype analysis device with high throughput, high precision and low cost is urgently needed to meet the requirement of acquiring phenotype data related to plant growth, yield, quality, tolerance to biotic and abiotic stresses and the like.
