Plant online nuclear magnetic resonance imaging detection analyzing device under artificial climate

Abstract

The invention relates to a plant online nuclear magnetic resonance imaging detection analyzing device under artificial climate, which comprises an artificial climate box and a nutrient solution oxygenation circulating mechanism, wherein the nutrient solution oxygenation circulating mechanism is installed inside a box body; the nutrient solution oxygenation circulating mechanism comprises a magnetic body box and a nuclear magnetic resonance test tube with a funnel-type plastic tube on the upper part; an upper cover and the lower bottom of the magnetic box body are respectively provided with a round mouth, and the nuclear magnetic resonance test tube is arranged inside the magnetic body box; and the device also comprises a nuclear magnetic resonance radio-frequency probe; the nuclear magnetic resonance radio-frequency probe wraps the nuclear magnetic resonance test tube; the bottom of the nuclear magnetic resonance test tube is connected with a nutrient solution vessel through a hose via an electromagnetic valve; the funnel-type plastic tube on the top of the nuclear magnetic resonance test tube is connected with a water pump which is arranged inside the nutrient solution vessel through a hose; and the nutrient solution vessel is connected with an air pump through a hose. The plant online nuclear magnetic resonance imaging detection analyzing device has beneficial effects that the technical bottleneck for bioassay of plant roots can be broken through, and the real-time monitoring of the state of the water plant roots can be realized without complicated operation.

Description

technical field [0001] The invention relates to a detection and analysis device, in particular to an online nuclear magnetic resonance imaging detection and analysis device for plants under artificial climate. Background technique [0002] Plants absorb water and mineral nutrients in the soil through their roots, so the water status of roots has always been a hot research field in botany. The roots of plants growing in a natural state have many branches and various shapes, and the sampling of the roots will inevitably cause damage. Hydroponics with nutrient solution is an effective means to ensure the integrity of the root system, and it is also a commonly used method for the study of plant root water and nutrition. [0003] Low-field 1H-NMR is a completely non-destructive and non-contact detection technique using protons as probes. Most living plant organs contain more than 85% water, so 1H-NMR has broad application prospects in the study of plant water physiology. It is ...
