Description

The dynamic photosynthetic instrument in leafy room

Technical field

The invention belongs to plant photosynthesis, Water Physiology fields of measurement, be specifically related to a kind of semi open model, monitor the device of multiple leaf photosynthesis, transpiration rate continuously.

Background technology

At present inside plant photosynthesis, Water Physiology fields of measurement, leaf photosynthesis, rising measuring method, applying maximum is portable measurement apparatus photosynthetic, rising, it is by airtight leaf folder that this device has continued to use traditional method, leaf folder top is sealed by glass or other transparencies, under undernatured state, manual control envirment factor could be measured. Structure is to utilize sampling trachea and electromagnetic valve to carry out timesharing switching through blade with without the moisture of blade, its shortcoming is owing to it is closed system, can not measure continuously for a long time, can only transient measurement, photosynthetic, the transpiration rate of instantaneous blade can only be understood, and also be the measurement of individual blade, due to transient measurement, factor of influence is relatively more, so measurement error is relatively larger, and finally also photosynthetic, transpiration rate situation in bad accounting 1 day.

If above-mentioned Portable type measurement unit needs long-term measurement continuously, it is necessary to increases temperature control system, if temperature controls improper, has loss of moist, it will measurement is had a huge impact; Temperature-control bodies architecture is complicated simultaneously, controls difficulty big, and power consumption is high, and maintenance cost is high.

Traditional method automatization level is low, and labor intensity is big, moreover measurement data is imperfect, it is necessary to statistics, inaccurate.

Domestic device is few, and external apparatus measures installation cost is high, and maintenance and maintenance are inconvenient.

Summary of the invention

For the problems referred to above, present invention is primarily targeted at and a kind of simple in construction is provided, measure semi open model accurately, to synchronize to measure continuously multiple plant leaf blades photosynthetic, the device of transpiration rate.

This invention address that the technical scheme that above-mentioned technical problem adopts is: as shown in Figure 1, continuous measurement is photosynthetic, transpiration rate device is mainly pressed from both sides array A and console controller B by leaf and forms, this leaf folder array A is made up of several leaves folder, agitation fan is had in each leaf folder, leaf folder top is naked leakage, bottom is semi-enclosed, it is necessary to time opens, it is not necessary to time is closed; Air pump, electromagnetic valve, CO2 analyzer, moisture parser in main frame, measurement time, sensor measurement, control pump valve execution etc. are controlled by console controller by presetting program, gather and store. This console controller is not belonging to the application content of the present invention, therefore not describes in detail at this. The present invention to apply for that the core component that has of protection is semi open model leaf photosynthetic, rising folder and multiple-blade synchronization measuring method photosynthetic, rising continuously.

Core component: semi open model leaf presss from both sides, as shown in Figure 2, modular construction arrangement on single leaf folder is as follows: above the blade of leaf folder maxillary 1 front end, relative atmospheric is exposed, the lower surface of maxillary has Magnet 2, Magnet bottom is foam pad 3, leaf folder lower jaw 4, the upper front end of leaf folder lower jaw is Magnet 5, it it is foam pad 6 above Magnet, there is light intensity sensor 7 leaf folder lower jaw middle part, air-temperature sensor 8 and leaf temperature sensor 9 is had bottom leaf folder lower jaw, air inlet 10 on the left of lower jaw, there is gas outlet 11 on right side, bottom lower jaw, 12 is semi-enclosed, open when needing, close time unwanted.

Adopting technique scheme, the technology of the present invention advantage is in that surrounding sample measuring principle, and semi open model, synchronization are monitored photosynthetic, the transpiration rate of multiple blades continuously and can be realized completely.

Accompanying drawing explanation

Fig. 1 and Fig. 2 is the structural representation of invention.

Detailed description of the invention

In order to describe the structure of the present invention, feature and effect in detail, now semi open model, multiple-blade measuring method photosynthetic, rising continuously is described in detail as follows:

(1) without the CO2 of blade, moisture measurement process:

Blade is clipped by semi open model leaf folder, when pressing from both sides completely after completely, leaf area A is known, leaf presss from both sides the volume V of whole cavity it is known that console controller controls booster air pump, and electromagnetic valve is switched to reference gas passage (being exactly the passage not past blade), through t0 after a while, the result that such CO2 sensor provides result C0, moisture transducer provides is RH0, this value by main frame collection, store, in order to following calculating.

(2) through the CO2 of blade, moisture process:

After terminating without the moisture measurement of blade, console controller controls booster air pump, and electromagnetic valve is switched to sample gas passage (being exactly the passage through blade), through t1 after a while, the result that such CO2 sensor provides result C1, moisture transducer provides is RH1, this value by main frame collection, store.

(3) calculate: can be calculated by above-mentioned steps (1) and (2) and obtain photosynthetic rate P=V* (C0-C1)/A/ (t0+t1), transpiration rate E=V* (RH1-RH0)/A/ (t0+t1). This value is stored by main frame, and the parameter simultaneously stored also has current date-time, current light intensity etc., because being continuous monitoring, time parameter is extremely important.

(4) first leaf folders are measured complete, and main frame is switched to again second leaf folder, carries out above-mentioned steps (1), (2), (3) equally, completes the measurement of second leaf folder, measure complete until all of leaf presss from both sides the array first round. Starting again goes round and begins again returns to first leaf folder upper continuation the second wheel measurement, and every day is all the work of such 24 hours. Here it is whole semi open model, continuously measurement process photosynthetic, rising.

(5) through such measurement, what the not Photosynthetic rate in the same time in last 1 day just will be apparent from is aware of, and accumulative total amount is also aware of easily.

The present invention to live body monitoring in 24 hours, can save substantial amounts of manual labor, it is thus achieved that abundant reliable data in measurement process. Its simple in construction, flexibly, easy to operate, technical characterstic is distinct, and measuring method novelty is stronger.

It should be noted that the foregoing is only presently preferred embodiments of the present invention, all equivalent structure transformations done according to description of the present invention, claims and accompanying drawing, should be included in the scope of patent protection of the present invention.
