Plant root system growth experiment device

Abstract

The invention discloses a plant root system growth experiment device, and relates to an experiment device. A cylindrical housing of the device is an uncovered cylinder, and the bottom face of a coveris a lower fixing disc; multiple concentric circle lug bosses of which the circle centers are the center of a bottom disc are arranged at the inner side of the lower fixing disc; stainless steel screen cloth is rolled into cylinders as cylindrical soil storage bodies, and the joints are fixed with stainless steel iron wires; an upper fixing disc is formed by connecting two perpendicular hollow rings of which the diameters are connected, and the size of the upper fixing disc corresponds to those of the lug bosses and the lower fixing disc; the cylindrical soil storage bodies are connected withthe corresponding lug bosses of the lower fixing disc in a matched mode according to the diameters, and then the upper fixing cover is connected to the corresponding soil storage bodies and the cylindrical housing. The plant root system growth experiment device is more suitable for obtaining truthful plant rhizosphere data when simulating a realistic plant growth state; the problem that a rhizosphere incubator limits plant root system growth and cannot precisely distinguish different rhizosphere areas is solved, and thus plant rhizosphere research is more reasonable and precise.

Description

technical field [0001] The invention relates to an experimental device, in particular to a plant root growth experimental device. Background technique [0002] The root system is an important growth organ of plants and a dynamic interface between soil and plants. Its main function is to absorb water and mineral nutrients from the soil and transport them to the aboveground parts for their use, while fixing plants in the soil. The root system plays a very important role in the plant's perception of environmental changes and its interaction with the environment. The root system can sense the change of environmental factors and pass it on to the aboveground part, so that the aboveground part can make an adaptive response. Therefore, the disciplines of plants, ecology, and environment have extensively carried out research on the morphological characteristics of plant roots, metabolic activity, root exudates, and the relationship between plants and soil, among which the study of ...
