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 for plant root growth under different growth conditions, in particular to a display system for observing plant root growth comparative experiments that can meet the needs of continuous growth of plants by parallel cultivation of hydroponics. Background technique

[0002] Roots are sessile plants that absorb and transport water and nutrients from the soil. "Comprehensive understanding of plant root development, root group distribution, the vitality of roots to absorb water and nutrients in different growth periods, and root changes 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 root-related research.

[0003] The traditional root observation box method, plastic pipe soil column method, mesh bag method, three-dimensional coordinate container method and other experi...
