Description
Technical field
The utility model relate to a kind of can the continuous monitoring rubber tree and the probe of other latex dust plant phloem turgescence real-time change.
Background technology
The plant phloem turgescence is the direct driving force that the product of its photosynthesis manufacturing is transported to the storehouse end by the source end.Accurately measuring and study plant phloem turgescence and regulation mechanism thereof is to understand fully the basis of plant phloem organism transhipment mechanism.Latex of panama rubber tree is that its bast latex dust cell comes to harm and coerces a kind of liquid tenuigenin that flow out the back.The latex dust turgescence is the motive power of rubber tree binder removal, and is closely related with the output of rubber tree.Simultaneously, because of having the reference index that real economy is worth for natural rubber production provides, rubber tree is one of the most thorough plant of studying in present all latex dust plants, also is the good pattern plant that the research bast is reprinted mechanism.
The technology that is used to measure rubber tree latex dust turgescence at present can reduce two types, i.e. capillary tube technique and pressure air pump method.The kapillary determination method is proposed by Buttery and Boatman (1964) at first, and Milburn and Ranas inghe (1996) and Yeang (2005) have carried out minor modifications to its structure.Its device basically all is to be made up of kapillary and coupling that one one end seals; At first use the draw point identical on bark, to make a call to a hole during mensuration until xylem with capillary-pressure cell link ends diameter; Then when taking out draw point, not having tangible latex to flow out; Immediately capillary-pressure cell is inserted bark, through measuring the length before and after the air column compression in the kapillary, P1V1=P2V2 tries to achieve the rubber tree turgescence through the gas equation formula then.The defective of this assay method is (1) link and bark poor sealing, causes measuring failure easily; (2) be full of air in the pressure gauge, because of the bigger mensuration accuracy of air compressibility not high; (2) capillary-pressure cell can only use 1 time and can only measure the maximal value in certain period, can't realize continuous real-time monitoring.In order to attempt realizing real-time monitoring; Milburn and Ranasinghe (1996) has set up a kind of pressure air pump method; But the air pump complex structure and the heaviness of its use cause and make loaded down with trivial details, operation and can't a people accomplish and when the inner latex of control device interface, be easy to destroy sealing.In addition; Because the restriction of structure etc.; Its device is inner, and what still fill is air, and the build-up of pressure pump is insensitive to the reaction that system's internal pressure changes, measured value is inaccurate, and the mobile meeting at latex interface is left a trace and caused control subsequently to measure and can't carry out in the mensuration process.
The utility model content
The purpose of the utility model be to provide a kind of simple in structure, easy to use, preparation easily, good airproof performance, precise and high efficiency and can realize the rubber tree latex dust turgescence continuous real-time monitoring probe of continuous real-time monitoring.
To achieve these goals; The technical scheme of the utility model is: a kind of rubber tree latex dust turgescence continuous real-time monitoring probe is provided; Wherein, mainly constitute by organic glass micro pressure chamber, Metallic rod, spiral micrometer head, pressure transducer, liquid-transfering gun suction nozzle and data acquisition unit; The head of said organic glass micro pressure chamber is equipped with the liquid-transfering gun suction nozzle; Top, organic glass micro pressure chamber is connected with pressure transducer; Rear portion, organic glass micro pressure chamber is connected with the spiral micrometer head through Metallic rod, and pressure transducer is connected on the data acquisition unit; Said spiral micrometer head comprises digital display spiral micrometer head and micrometer head screw rod.
The utility model is simple in structure, easy to use, critical piece can repeatedly use, good airproof performance, and easy to operate, detection speed is fast, precision is high, good reproducibility, the real-time change of ability continuous monitoring rubber tree latex dust turgescence.

Embodiment
For the technology contents, the structural attitude that specify the utility model rubber tree latex dust turgescence continuous real-time monitoring probe, be described further below in conjunction with embodiment and conjunction with figs..
As shown in Figure 1, the utility model rubber tree latex dust turgescence continuous real-time monitoring probe mainly is made up of organic glass micro pressure chamber 3, Metallic rod 2, spiral micrometer head, pressure transducer 4, liquid-transfering gun suction nozzle 5 and data acquisition unit 6; The head of said organic glass micro pressure chamber 3 is equipped with 200 μ L liquid-transfering gun suction nozzles 5; 3 tops, organic glass micro pressure chamber are connected with pressure transducer 4; Rear portion, organic glass micro pressure chamber is connected 7 through Metallic rod 2 with digital display spiral micrometer head, and the right-hand member of digital display spiral micrometer head connection 7 links to each other with micrometer head screw rod 1; Pressure transducer 4 is connected on the data acquisition unit 6; Said spiral micrometer head comprises digital display spiral micrometer head 7 and micrometer head screw rod 1.Data acquisition unit 6 is connected the pressure that the pressure transducer 4 that data acquisition unit 6 can monitor in real time, show and record is connected with organic glass micro pressure chamber is measured to simultaneously with computer.Can be in the mensuration process through the position of latex in the micrometer head screw rod 1 control latex dust turgescence probe with silicon oil interface, thus judge further whether latex dust turgescence measured value is accurate, and study the regulation rule of rubber tree latex dust turgescence
Be full of silicone oil in this rubber tree latex dust turgescence continuous real-time monitoring probe in the mensuration process.During mensuration, at first use special syringe needle (can avoid damaging the rubber tree cambium layer, and take the wood chip that when punching produce out of prevent to measure system jams) on bark on the rubber tree, to make a call to a diameter and the liquid-transfering gun suction nozzle is suitable, the degree of depth is until the hole of xylem; Take out syringe needle, when not having tangible latex to flow out, then this latex dust turgescence probe that is full of silicone oil is installed in the rubber tree location; Further seal with Instant cement, itself and rubber tree bark latex dust system form the pressure system of a sealing.Because the interface that the existence of latex dust turgescence, the inner latex of latex dust can get into probe very soon and form a latex and silicone oil also finally is equilibrated at the privileged site of liquid-transfering gun suction nozzle; Can realize continuous, real-time monitoring, demonstration and the record of rubber tree latex dust turgescence through pressure transducer continuous real-time image data.
The above disclosed preferred embodiment that is merely the utility model can not limit the interest field of the utility model certainly with this, so according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
