A system for obtaining root phenotypes of field crops

Abstract

A system for obtaining root phenotypes of field crops. The present invention includes a first-direction root phenotype acquisition subsystem and a second-direction root phenotype acquisition subsystem that are perpendicular to each other. Among them, the first-direction root phenotype acquisition subsystem can directly obtain the overall phenotype data of crop roots through root window monitoring. Its collection method is fast and convenient. The root phenotype of the second direction can be obtained through the root canal system. The root canals are buried at different depths underground, and the 360° phenotype data near the crop root system at this depth can be completely obtained, which can facilitate the detailed structure of the crop root system in different dimensions. for accurate sampling. In addition, the root canal is less affected by the outside world, and data and images of soil moisture, temperature, and crop root growth parameters of various plant roots can be collected in real time, dynamically, and around the clock.

Description

technical field [0001] The invention relates to the technical field of crop phenotype acquisition, in particular to a system for acquiring field crop root phenotypes. Background technique [0002] Crop phenotype is part or all of the identifiable physical, physiological and biochemical characteristics and traits produced by the interaction between genes and the environment, including the structure, composition and growth and development process of the crop, which not only reflects the expression regulation at the molecular level, but also It reflects complex traits such as plant physiology, biochemistry, morphological anatomy, and stress resistance. [0003] The development of functional genomics and gene technology in the field of crop breeding is the most convenient and effective means to increase grain production. Phenotype is the external expression of crop genes, which is the result of the interaction between the crop's own genes and the external environment. Therefor...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a system for obtaining root phenotypes of field crops. The present invention can monitor the system through the root window in the first direction and the root canal in the second direction in the state closest to nature. The monitoring system acquires and analyzes the phenotypes of crop roots in two dimensions, which solves the problems that existing root monitoring equipment cannot carry out large-scale experiments in the field, and cannot accurately and automatically acquire and analyze crop root phenotypes.
