Display system suitable for comparing and observing growth of plant root systems

Abstract

The invention relates to a display system for comparing and observing the growth of plant root systems under different growing conditions, particularly to a display system which utilizes water culture method for parallel cultivation, can satisfy continuous growth requirements of plants and is used for observing growth comparison experiments of plant root systems. The display system comprises three main parts which are a cultivation tank, a nutrient fluid circulation and regulation device and a movable stand; the cultivation tank and the nutrient fluid circulation and regulation device are respectively arranged on the movable stand and are communicated through a pipeline; and nutrient fluid required by the cultivation tank is supplied by the nutrient fluid circulation and regulation device. The display system provided by the invention can not only be used for teaching works such as comparing and displaying geotropism, nutrient-tropism, hydrotropism and other growth characteristics of plant root systems, but also provide a convenient experimental tool for continuously comparing and observing growth conditions of plant root systems under different environmental conditions, and the problems in the prior art such as incapability of measuring intuitionally and all sidedly, inaccurate simulation and observation results, lack of comparative observation function, and the like are solved.

Description

technical field [0001] The invention relates to a comparative observation and display system of plant root growth under different growth conditions, in particular to a display system for comparative experiments of plant root growth that can meet the requirements of continuous plant growth and can be cultivated in parallel by hydroponics. Background technique [0002] Roots are the organs that anchor plants and absorb and transport water and nutrients from the soil. "Comprehensively understand the development of plant roots, the distribution of root groups, the activity of roots absorbing water and nutrients in different growth stages, and the changes of roots in different environments" is the main content of root research. How to accurately sample, measure, and observe plant roots has become a technical bottleneck restricting research on root systems. [0003] Traditional root observation box method, plastic tube soil column method, mesh bag method, three-dimensional coordi...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a display system for comparing and observing plant root growth experiments that can simulate soil physical conditions to meet the continuous growth requirements of plants by using parallel culture in hydroponics, so as to solve the unintuitive and comprehensive problems existing in the prior art. Measurement, as well as simulation, inaccurate observation results, lack of comparative observation functions, etc.
