Abstract
The utility model relates to a leaf chamber structure for determining photosynthesis of non-leaf organs in the countryside, wherein the leaf chamber is made of transparent organic glass, and is characterized in that the leaf chamber consists of two opening and closing semicolumn housings; a sealing rubber and plastic tablet is stuck on a joint surface of the semicolumn housing; a thermoelectric pair, an air return hole, and a mounting and junction panel are respectively arranged on one of the semicolumn housings. Through changing the size of the leaf chamber housing, the utility model can also be applied to in situ determination of photosynthesis, respiration, and transpiration rate of non-leaf photosynthetic organs of fruits and leguminous beanpod, etc.. The leaf chamber structure for determining photosynthesis of non-leaf organs in the countryside satisfactorily solves a problem of current leaf chambers that photosynthesis determination of non-leaf organs of a variety of plants can not be carried out.
Description
One, technical field
The utility model belongs to measurement, testing tool manufacturing technology field, is specifically related to a kind of can be used for measuring under the field condition ear of crops portion or the photosynthetic leaf cell structure of other non-foliage organ.
Two, background technology
Photosynthesis is the process that the plant photosynthesis organ utilizes luminous energy that carbon dioxide, water and inorganics are converted into carbohydrates and put oxygen.Human present food and the widely used fiber even the energy nearly all directly or indirectly derive from the photosynthate of plant.The variation of global environment has at present caused the extensive concern that scientific circles change the ecosystem, and wherein primary problem is exactly to understand the response of photosynthesis of plant to global environmental change, so the research of photosynthesis of plant is more and more paid close attention to.The photosynthesis measurement instrument is research photosynthesis one of instrument the most widely, research and development through two more than ten years, official listing LI-COR series (U.S. LI-COR company arranged respectively, representing instrument is the portable photosynthesis analyzer of LI-COR6400), PPS series (Britain PP Systems scientific instrument company, representing instrument is CIRAS), HCM series (German WALZ company, representing instrument is the portable photosynthesis analyzer of HCM-1000) etc., wherein LI-COR series is most widely used in the university and the scientific research institution of China.According to incompletely statistics, China only LI-COR6400 just have an appointment 600 in use.These photosynthesis measurement instrument, its measuring principle and construct similarly all is by CO in the leaf chamber
2, H
2The reference of gases such as O changes and the area of being correlated with is measured calculating photosynthetic rate, respiratory rate and transpiration rate.Therefore, the leaf chamber is very important in the photosynthesis measurement instrument.Existing leaf chamber is all designed according to plant is leaf, and majority is decided to be 2 * 3cm
-2Rectangle leaf chamber (as: LI-COR 6400).Yet the photosynthetic organ of plant is a leaf not only, and other organ also has stronger photosynthetic capacity, and as fringe portion of crop and the fruit of fruit tree etc., they have significant effects to the output and the quality of agricultural product.Therefore, the scientific research personnel increases day by day to the concern of the photosynthetic organ of non-leaf.
According to the principle of photosynthetic mensuration, measure the photosynthetic leaf chamber of fringe portion and need satisfy following condition:
1. transmittance height---fully guarantee the illumination condition of the photosynthetic organ that leaf is indoor;
2. good sealing---guarantee the indoor middle CO of leaf
2, H
2Gas concentrations such as O change true performance plant;
3. gas can evenly distribute rapidly in the leaf chamber interior;
4. can carry out that fast measuring---minute is short more, the indoor temperature disturbance of leaf is more little;
5. easy and simple to handle;
6. adapt to wide.
Still there is not at present the desirable leaf cell structure that can be used for measuring the photosynthetic organ of the non-leaf of plant.
Three, summary of the invention
The purpose of this utility model is to design a kind of photosynthetic novel leaf cell structure of the non-foliage organ of all kinds of plants that can be used for measuring under the field condition.
Technical solution of the present utility model is: the photosynthetic leaf cell structure of the non-foliage organ of a kind of field measuring, make with transparent organic glass the leaf chamber, it is characterized in that but the leaf chamber is made of two semicolumn cavitys 1 and 2 of folding, post sealing rubber and plastic sheet 5 on semicolumn cavity 1 and 2 the faying face, be respectively equipped with thermopair 6, return-air hole 7 on the semicolumn cavity 1 and web joint 8 is installed.
During mensuration, earlier semicolumn cavity 1 is installed on photosynthetic analyzer and the corresponding support by web joint 8 is installed, connects return-air hole 7 and photosynthetic analyzer with a flexible pipe, thermopair 6 inserts the corresponding socket of photosynthetic analyzer; With wheat to be measured or paddy rice, stem under the fringe of ear of crops portions such as buckwheat, but put into two semicolumn cavitys 1 and the 2 transparent cavitys that constitute by folding by the sealing and fixing hole 4 of two semicolumn cavitys 1 and 2 belows, stem is coated vaseline by the part in sealing and fixing hole 4 under the fringe, with bolt by a plurality of on two semicolumn cavitys 1 and 2 faying faces be connected seal bore 3 with two semicolumn cavitys connect be sealed to an integral body after, can cooperate with existing various photosynthetic determining instrument, measure the photosynthetic of various ear of crops portion in the open air under the condition, breathing and transpiration rate etc.
Four, description of drawings
Fig. 1 is the structural representation of leaf chamber, 1 and 2 are respectively transparent organic glass semicolumn cavity among the figure, post sealing rubber and plastic sheet 5,3 on semicolumn cavity 1 and 2 the faying face for connecting seal bore, 4 is the sealing and fixing hole, is respectively equipped with thermopair 6, return-air hole 7 on the semicolumn cavity 1 and web joint 8 is installed.
Five, embodiment
Embodiment 1
Be used to measure the leaf chamber parameter of wheat or ear of crops portions such as paddy rice, buckwheat:
Make two semicolumn cavitys 1 and 2, two semicolumn cavitys 1 and the 2 transparent cavity cavity diameter 6cm that constitute, high 18cm with the colourless organic glass of high transmission rate;
Sealing rubber and plastic sheet 5 adopts transparent silicon rubber, thickness 4mm;
The aperture in sealing and fixing hole 4 is 3/3.5mm, and half taper type is beneficial to match with stem shape under the ear of crops portion up-thin-low-thick fringe;
The aperture that connects seal bore 3 is 5.5mm, uses a plurality of M5 * 25 bolts (not drawing in the accompanying drawing) to connect sealing;
Return-air hole 7 apertures are 10mm.
Use for convenience, can also use hinge that two semicolumn cavitys 1 and 2 are linked to be an integral body.
Embodiment 2
Change leaf chamber body size, the utility model also can be used for photosynthetic, the breathing and the transpiration rate of the photosynthetic organs of non-leaf such as beanpod of in-site detecting fruit tree fruit, pulse family.When leaf chamber body volume during, can also in semicolumn cavity 1, install mini-fan additional greater than 2L.
Beneficial effect: the utility model has satisfactorily resolved the light that the non-foliage organ of all kinds of plants can't be carried out in existing leaf chamber Cooperation mensuration problem.
