System for regulating and controlling growing environment of hydroponic plants and acquiring phenotypic images

Abstract

The invention provides a system for hydroponic plant growth environment regulation and control and phenotypic image acquisition. Nutrient solution is pumped into each hydroponic tank through respective independent connecting pipelines, and a plurality of mutually independent plant cultivation tank environments are respectively formed through the sealing effect of the hydroponic tanks and the transparent heat insulation covers. According to the system, the growth environment parameters of plants can be accurately regulated and controlled in real time through the sensors and the environment devices in the plant culture boxes, different culture conditions are simulated in the culture boxes, and research experiments of influences of different environment factors on plant growth and development are achieved under one system. On the basis, a plant phenotype image acquisition device comprising a multi-angle and multi-azimuth RGB camera group and a multi-spectral camera is also constructed outside the culture box, and can acquire multi-spectral images of plant stems and leaves and RGB images of the whole plant in the whole overground and underground range in a high-throughput manner on the premise of not influencing the growth and development of the plant; dynamic continuous collection of phenotypic characteristics of the overground part and the root system of the plant in different growth environments is realized.

Description

technical field [0001] The present application relates to the technical field of hydroponic crop phenotype acquisition, and specifically relates to a system for hydroponic plant growth environment regulation and phenotypic image acquisition. Background technique [0002] Plant phenotypic traits such as plant height, greenness, vegetation index, plant leaf area and root length are the result of the interaction between plant intrinsic genes and the external environment. Plant phenotypes are very sensitive to environmental changes, and there may be large differences in plant growth patterns and plant phenotypic traits under different environmental conditions. Analyzing the phenotypic differences of plants under different environmental conditions will help researchers further analyze the interaction mechanism between plant genotypes and the environment. [0003] The controllable environmental variables in the process of plant growth are the prerequisite and guarantee for obtain...

Problems solved by technology

However, the plant hydroponic process is a complex, time-consuming and labor-intensive process. Especially in the experimental process, researchers should use the time for deep thinking, which is often replaced by nutrient solution replacement, environmental variable regulation, and manual measurement of plant phenotypic traits. chores take up
