Plant water condition analyzer plant water potential meter

I. 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 specifications 1, measuring range: 0-10.00 MPa; digital display reading 2, reading accuracy: 0.01MPa3, shape volume: 550mm × 280mm × 350mm4, instrument net weight: 9kg three, the instrument's measurement principle plants in the soil - In the plant-atmosphere continuous system, the roots continuously absorb water from the soil, and the leaves continuously lose water to the surrounding environment. In this water potential gradient system, the root-stem-leaf also has a water potential gradient, 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 the plant branches or leaves are cut, the tensioned water column in the conduit breaks and the water column contracts from the incision to the inside. Put the cut material into the pressure chamber of the instrument (see below for the operating procedure), so that one end of the slit extends out of the room and is pressurized, so that the tension in the branches or leaves is rebalanced and the small water column is pushed back to the surface of the cut surface. All the pressure is the water potential of the plant.
