Plant water condition analyzer plant water potential meter model: HA-ZLZ-3000
First, the use of the instrument
The HA-ZLZ-3000 plant moisture condition measuring instrument is an instrument for determining the plant water potential (Ψ) and its constituent components and extracting the xylem conduit juice for component analysis. It can be used to study the water relationship of plants and the relationship between plants and the environment. Suitable for plant physiology, ecology, agronomy, forestry and pasture research. According to this, it is one of the important instruments for teaching and scientific research to guide the rational use of water and drought-resistant breeding of crops and forests. It is easy and fast to operate, both indoors and outdoors.
Second, the instrument's specifications
1. Measurement range: 0-10.00 MPa; digital display reading
2, reading accuracy: 0.01MPa
3, the shape of the volume: 550mm × 280mm × 350mm
4, instrument net weight: 9kg
Third, the instrument's measurement principle
In the soil-plant-atmosphere continuous system, the roots continuously absorb water from the soil, and the leaves continue to move around.
The environment loses moisture. In this water potential gradient system, there is also a water potential gradient in the root-stem-leaf of the plant, which makes the xylem duct
The small water column is affected by the negative pressure of the low water potential of the air, forming a pulling force for the upward transport of moisture. When plant branches or leaves are cut
At this time, the tensioned water column in the conduit breaks and the water column will contract from the inside to the inside of the slit. Load the cut material into the instrument
In the pressure chamber (see below for the operating procedure), so that one end of the slit extends out of the room to seal it, pressurize it, and make it inside the branches or leaves.
The tension rebalance pushes the small water column back to the surface of the cut, and all the pressure is the water potential of the plant.
