Plant cultivation method based on in-situ dynamic observation and measurement of plant root system

Abstract

The invention discloses a plant cultivation method based on in-situ dynamic observation and measurement of a plant root system.The method comprises the following steps: 1) designing a transparent cultivation container and a transparent growth medium; 2) sterilizing seeds and accelerating germination, transplanting seedlings to the transparent cultivation container in step 1) after budding, keepingthe plant root system growing naturally in the transparent growth medium, and scanning and observing the root system by a three-dimensional laser scanner.According to the plant cultivation method disclosed by the invention, the natural growth of the plant root system in a transparent growth environment is realized, through performing three-dimensional visualized analysis on the in-situ growth conditions of the plant root system, the three-dimensional growth conditions of the plant root system can be directly reflected without destructive detection, and dynamic observation is realized.In addition, by changing the components of nutrients added to the culture medium, the conditions of nutrient supply to the plant root system by the growth medium can be adjusted.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a plant cultivation method based on in-situ dynamic observation and measurement of plant roots. Background technique [0002] The root system is the main organ for plants to absorb nutrients and water. Only well-developed roots can meet the needs of plant growth. Therefore, the study of plant root growth is of great significance to understand the nutrient requirements of plants and their relationship with the environment. At present, some progress has been made in the study of root system, but under natural growth conditions, due to the opacity of the soil medium and the complexity of the root system structure, it is difficult to observe and measure in situ. Most of the root morphology and configuration data reported so far are data obtained by destructive sampling, not in situ data, and most of the studies on root architecture and nutrient efficiency are qualitative s...

Problems solved by technology

At present, the research on the root system has made some progress, but under natural growth conditions, due to the opacity of the soil medium and the complexity of the root system structure, it is difficult to observe and measure in situ

Most of the root morphology and configuration data reported so far are data obtained by destructive sampling, not in situ data, and most of the studies on root architecture and nutrient efficiency are qualitative studies, and there are few quantitative studies on root architecture and nutrient efficiency. See the report

In addition, most of the existing research is the study of root architecture data and nutrient efficiency at a certain moment, and there are no technical reports on the dynamic in-situ root architecture data and nutrient efficiency.
