Hydroponic device convenient for research on plant root systems and application thereof

Abstract

The invention provides a hydroponic device convenient for the research on plant root systems, which is characterized by comprising a transparent glass, a black glass sleeved outside the transparent glass, and a supporting floating plate arranged in the transparent glass, wherein the supporting floating plate is formed by combining black shading plastic cloth, a floating plate with the thickness of 0.3-1cm and a window gauze from top to bottom, small holes not penetrating through the window gauze are uniformly distributed in the supporting floating plate, and the supporting floating plate is provided with a lifting rope lifted upwards. The application of the device comprises the following steps: (1) germinal seeds are gently put into the small holes of the supporting floating plate, and the roots of the seeds penetrate through the window gauze; (2) the supporting floating plate carrying the seeds is put into the transparent glass, the supporting floating plate floats on nutrient solution, and the black glass is sleeved outside the transparent glass; and (3) the hydroponic device carrying the germinated seeds is moved into a sterile artificial climate box or sterile room for the hydroponics of plants. The hydroponic device can effectively prevent the influence of illumination on root system growth and development, and is convenient for the research on the root system growth and development, morphological structures and the like.

Description

technical field [0001] The present invention relates to a hydroponic device and its application which are convenient for plant root system research, in particular to a hydroponic device and its application which can effectively prevent the influence of light and algae on the growth and development of plant root system in an artificial climate box or a sterile room. Background technique [0002] The root system is the basis for the survival of the aboveground part of plants, but the natural root system is deep underground, and observation and research are very inconvenient. Due to the limitation of research methods, the research progress of the root system lags far behind the aboveground part in depth and breadth. [0003] Hydroponics is currently the most commonly used method for root research. Hydroponics can easily replace the culture medium, add nutrient factors that regulate root growth, growth hormones or stress factors, etc., precisely control various chemical component...

Problems solved by technology

However, the root system of hydroponic plants is often affected by light, and algae plants in the culture medium are easy to breed, and the algae competes with the plant root system for nutrients, affecting the growth and development of the root system, and the algae plants attached to the root system are difficult to remove, which is not conducive to the physiological, biochemical, and biological properties of the root system. Therefore, it is of great significance to invent a hydroponic device that can effectively prevent the influence of light on the growth and development of roots and prevent the growth of algae plants.
