Abstract

The invention provides a device for detecting xylem water conductivity and embolism vulnerability of ligneous plants. The device comprises a motor, an air compressor, a voltage stabilizer, a liquid storage tank, a base and a combined flushing interface which can be inserted into a detected stem section, wherein the motor, the air compressor and the voltage stabilizer are fixed on the base, and the motor is used for providing power to the air compressor; the voltage stabilizer is used for controlling the air compressor to output constant pressure required by detection, so that the consistency of detection conditions can be guaranteed; the voltage stabilizer, the air compressor and the liquid storage tank are connected through vent pipes, and the combined flushing interface is connected with the liquid storage tank through a liquid transmission pipe; the liquid storage tank consists of an injection hole, an air inlet, a transfusion hole, a lateral liquid level calibration gauge and a bottom draining hole, wherein the upper part of the injection hole is provided with a check valve, and the lower part of the transfusion hole is provided with a check valve; the air inlet at the upper part of the liquid storage tank is connected with the voltage stabilizer through a vent pipe, and the transfusion hole at the lower part of the liquid storage tank is connected with the combined flushing interface through a transfusion pipe; the combined interface comprises a plurality of single flushing interfaces with check valves.

Description

technical field [0001] The invention belongs to the field of plant physiology and ecology, and relates to a detection device for water transmission state and transmission capacity in plants, in particular to a detection device for xylem water conductivity and embolism vulnerability of woody plants. Background technique [0002] Among the factors limiting tree growth, water stress is the most common and has the greatest impact. About 1 / 3 of the world's regions are arid and semi-arid regions limited by water supply. Therefore, the research on the water relationship of woody plants, especially the research on the water transport capacity of xylem and the plugging characteristics of xylem, is currently a hot spot for tree physiology and ecologists. [0003] So far, there is no complete set of stable and precise devices specially used to detect xylem hydraulic conductivity and xylem embolism vulnerability of woody plants at home and abroad. This device is currently the only com...
