Description
Technical field
The present invention relates to a kind of plant roots pressure measuring devices, more particularly, to a kind of portable pressure measuring device and measurement
Method.
Background technique
In the case where high temperature, arid and severe cold occurs, air embolism fails to repair in time in plant, and blocks moisture exists
Transmission in plant xylem vessel, so that branch is withered or even withered.An important factor for root pressure is rehabilitation plant embolism it
One, the main means for measuring plant roots pressure at present are to take special equipment to measure in laboratory, and method is complicated, takes time and effort.
Summary of the invention
In view of the deficienciess of the prior art, the present invention provides portable pressure measuring device of one kind and measurement method, it should
Device can also be achieved the accuracy during user's measurement plant roots pressure, accelerate user's other than itself is small and exquisite, is convenient for carrying
Service efficiency.
To achieve the above object, the present invention provides the following technical scheme that
A kind of portable pressure measuring device, including barometer, the barometer are by one end wine of glass capillary
It shuts after smart lamp heating, and is injected distilled water in the glass capillary with microsyringe, the glass capillary enters
Silica gel hose, topping-up in the silica gel hose are socketed at water, the other end of the silica gel hose connects concentric reducer, greatly
Also topping-up in microcephaly.
Preferably, the capacity of the microsyringe is 100 μ l.
A kind of measurement method of portable pressure measuring device, the stem for the plant sample chosen or bar are clipped, described
The section of stem or bar is scabbled with blade, and the topping-up into the stem or bar, takes the silica gel hose of dimension size, set
On the stem or bar of plant sample and topping-up, described pressure measuring device is covered on silica gel hose；Second day dawn
One end of the barometrical glass capillary is withstood in preceding one end using T square, and the other end of the T square reads the hair
The reading Lpd of distillation water meniscus in thin glass tube；Silica gel hose, which is cut, with scissors then distills water meniscus in glass capillary
It begins to decline, reads Latm when meniscus is stablized；Substitute into formulaPlant roots pressure can be obtained.
The present invention has the advantages that the apparatus structure is simple by using above-mentioned technical proposal, easy to use,
Plant roots pressure not only can in time, be accurately measured, can also be handled in the case where not damaging plant itself with low temperature, arid etc.
Device is used in combination, and realizes the needs of user's difference research work, accelerates service efficiency, convenient and practical, functionality is had
The raising of effect.
Detailed description of the invention

Bar；7, T square.
Specific embodiment
In order to make those skilled in the art that the present invention may be better understood, with reference to the accompanying drawings and examples to this hair
Bright technical solution further illustrates.
- 3 pairs of embodiment of the present invention are described further referring to Fig.1.
A kind of portable pressure measuring device, including barometer 1, the barometer 1 are to use one end of glass capillary 2
It shuts, and is injected distilled water 3 in the glass capillary 2 with microsyringe, the glass capillary 2 after alcolhol burner heating
Enter to be socketed with silica gel hose 4 at water, the other end of topping-up in the silica gel hose 4, the silica gel hose 4 connects greatly
Microcephaly, also topping-up in concentric reducer.
Further, the capacity of the microsyringe is 100 μ l.
A kind of measurement method using portable pressure measuring device, the stem for the plant sample chosen or bar are clipped,
The section of the stem or bar 6 is scabbled with blade, and the topping-up into the stem or bar 6, takes the silica gel of dimension size
Hose, covers on the stem or bar of plant sample and topping-up, and described pressure measuring device is covered on silica gel hose；User
When preparing measurement plant roots pressure, root pressure measuring device was connect with plant sample in the same day, and measured and read before second day dawn
Data, institute's measured data are accurate；As shown in Fig. 2, the capillary of the barometer 1 was withstood before second day dawn using one end of T square 7
One end of glass tube 2, the other end of the T square 7 read the reading Lpd of 3 meniscus of distilled water in the glass capillary 2；
As shown in figure 3, being begun to decline with distillation water meniscus in scissors cutting silica gel hose then glass capillary, when meniscus is stablized
Read Latm；Substitute into formulaPlant roots pressure can be obtained, in which: Latm is in atmospheric pressure
(atmosphere) length of bubble 5 under the conditions of；Lpd is the length of (predawn) bubble 5 before dawn；Px is root pressure or sample
The hydraulic pressure of this xylem.
The present invention has the advantages that the apparatus structure is simple by using above-mentioned technical proposal, easy to use,
Plant roots pressure not only can in time, be accurately measured, can also be handled in the case where not damaging plant itself with low temperature, arid etc.
Device is used in combination, and realizes the needs of user's difference research work, accelerates service efficiency, convenient and practical, functionality is had
The raising of effect.
