Abstract
The invention discloses a living body measurement method and device of thickness of a rice leaf. The method comprises the following steps of: selecting the growing rice leaf as a measuring object; measuring the fixed position of the rice leaf by using a special leaf thickness measuring device; placing the fixed position of the leaf between a rice leaf contact plate and a base of the leaf thickness measuring device and keeping the fixed position away from the main vein of the leaf rice; when the full-leaf thickness of the fully spread rice leave is measured, measuring leaf tip, middle and base, wherein the base measuring point of the rice leaf is at 2/3 of the full leaf length; and averaging the measured leaf thickness data of three points, wherein the obtained average value is the thickness value of the full leaf. The method can directly measure the thickness of the living body rice leaf so as to improve the efficiency, simplify the operation, reduce the cost and improve the accuracy; and the method can perform living body measurement to the rice leaf thickness in the field so as to eliminate the sampling steps, implement the continuous tracking to the sample and eliminate the complex process of the data statistic analysis of the destructive sampling experimental data.
Description
Technical field
The present invention relates to a kind of method and apparatus of leaves of plants thickness, specifically is a kind of method and measurement mechanism thereof of living body measurement rice leaf thickness.
Background technology
The thickness of rice leaf is always all paid attention to by rice does the boundary, Japanese rice does scholar Song Dao and field, angle and proposes the thick index as the paddy rice fertilizer tolerability of leaf about the sixties in last century, and think that high-yield rice should have thicker blade, their this viewpoint is used till today always.Recently rice thinks that as the scholar vane thickness is one of 5 element factors of rice leaf form, is selection index important in the breeding and the efficient diagnosis index in the high-yield culturing, and points out that further vane thickness is the important leaf attitude factor that other factors are difficult to replace.The Yuan Longping points out further that then the sword-like leave of super hybridized rice is thick and directly is one of important evidence of the strong excellent combination of seed selection.
About the assay method of rice leaf, mainly be to adopt " specific leaf weight " to represent the thickness of blade, also there are the vernier caliper of employing, microscope and buoyancy method directly to measure.In the time of " but specific leaf weight " law amount vane thickness, the area that should measure blade is measured the weight (oven-dried weight) of blade again simultaneously, and it is more loaded down with trivial details to work, and the most important thing is to carry out qualitative description; And vernier caliper, measurement microscope and buoyancy method be except complicated operating process, and the measurement of all need exsomatizing can destroy sample and can not carry out track determining.Along with science and technology development, high spectral technique arises at the historic moment, the China Measures Institute had developed the YI-20010A plant leaf parameter measuring instrument in 2004, the YI-20010A plant leaf parameter measuring instrument is by Modern Transducer Technology, use the direct contact type measuring method, realization is to the real-time monitoring and the record of plant leaf blade one-tenth-value thickness 1/10 and ambient temperature and humidity, but vane thickness changes when extruding is measured, bring error to measurement, and do not see the directly report of mensuration aspect of relevant rice leaf list leaf thickness so far.The measurement that leaf is thick is the bottleneck of restriction paddy rice leaf thickness and correlative study.
Summary of the invention
In order to overcome above-mentioned deficiency, the object of the invention be to provide a kind of not only saved that raise the efficiency man-hour but also simple to operate, cost is very low, degree of accuracy improves, and can also make the method for the living body measurement rice leaf thickness of somatometry in the field to rice leaf thickness.

E, step B, step C and the measured thick data of leaf of step D are averaged, the mean value of gained is the one-tenth-value thickness 1/10 of full leaf.
Described leaf thickness measuring device, include thickness measure clock gauge, bracing frame and handle, described handle is connected with an end of bracing frame, the thickness measure clock gauge is located at the other end of bracing frame, bracing frame is to constitute by base and with the vertically arranged back up pad of base, described sounding rod is vertical with base, and the lower end of sounding rod is provided with the rice leaf contact plate parallel with base.
Described back up pad is provided with lever and measures actuating lever, and measuring actuating lever is balance pivot and hinged with back up pad with the back up pad, and the one end is the finger start end, and the other end is connected with sounding rod.
In the described thickness measure clock gauge and the top that is positioned at sounding rod is provided with so that the stage clip that sounding rod resets, and this stage clip guarantees that analyzing rod bottom surface both can touch the blade face, and the spring pressure of this moment is zero to be unlikely to push blade and to produce error simultaneously.
Beneficial effect of the present invention: the present invention can break away from the constraint of relevant rice leaf thickness measuring method in the past, when live body rice leaf is directly measured, not only raise the efficiency but also simple to operate, cost is very low, degree of accuracy improves, and can also do somatometry to rice leaf thickness in the field, both save the operation of sampling, can implement the continuous tracking of sample, the complicated processes of removing the statistical study of destructive sampling experimental data from again.
