Abstract
The utility model relates to a diffuse reflection spectrum mensuration equipment of peanut monomer seed, which is based on Fourier transform infrared spectrum technique and adopts diffuse reflection mensuration mode. The utility model comprises perpendicularly fixed base with fixed bracket; wherein, a fixed clamp and a flat is arranged on the fixed bracket and can move horizontally and vertically. The solid detector with head over heels, which is connected with fiber, is fixed on the fixed bracket through the fixed clamp. The white ceramic is arranged on the flat head against the solid detector and the sample washer is arranged on the white ceramic. The utility model has the advantages of simple operation, convenient installation, small spectrum mensuration error and good recurring capability, which can meet the high grease breeding demand of the peanuts. Based on the utility model, the nondestructive oil mensuration of single peanut seed is possible.
Description
Technical field
The utility model relates to the quantitative analysis tech field of peanut seed quality component, specifically is meant the single seed diffuse reflection spectrum determinator of cultivating peanut.
Background technology
The conventional chemical method of measuring the peanut seed oleaginousness generally adopts the Soxhlet method.The sampling mode of this assay method and sample pretreating method are destructive, also have time and effort consuming, loaded down with trivial details, the more high shortcoming of cost of determination of mensuration program.In peanut quality breeding and genetic research, very need analytical approach real-time fast, simple to operate, that do not destroy sample.Be in the peanut quality breeding of purpose to improve oleaginousness, press for the analytical technology that detects to the segregating generation non-destructive peanut single seed oleaginousness in early days, make the breeder select the high oiliness shape in that variation is from generation to generation directed, thus make high oil base because of added up and can with high yield, excellent genes integration such as disease-resistant.With doubting, the non-destructive analysis technology has not become the bottleneck of peanut high-oil breeding research, seriously hinders the raising of breeding efficiency.
Over past ten years, because the combination of near-infrared spectrum technique, Chemical Measurement and computer software technology, near-infrared spectrum technique is developed on the attributional analysis of natural complex material rapidly, range of application more and more widely, and is and fast, easy and simple to handle and to characteristics such as the non-destructives of sample and come into one's own day by day with its finding speed.Though it is a lot of to use the report of near-infrared spectrum technique anal yzing agricul products quality component, but do not see up to now the report of using near-infrared spectrum technique nondestructively measuring peanut single seed oleaginousness is arranged, this process need adopts the diffuse reflection mode to measure the single seeded diffuse reflection spectrum of peanut, does not more have the report about this class device.
Summary of the invention
The purpose of this utility model is exactly in order to solve above-mentioned the deficiencies in the prior art part, and a kind of simple to operate, dress sample peanut single seed diffuse reflection spectrum determinator easily is provided.
The described in the utility model one single seed diffuse reflection spectrum determinator of cultivating peanut, it is characterized in that, it comprises that vertical fixing has support bracket fastened base, the platform that geometrical clamp is installed on fixed support and can moves horizontally up and down, the head that connects fibre-optic solid probe is installed on the fixed support by geometrical clamp vertically downward, on platform, the white pottery porcelain is installed, lays the sample packing ring on the white pottery porcelain over against the solid probe place.
In order to realize the utility model better, platform can manually be controlled by knob, and level moves up and down.
The utility model compared with prior art has following advantage and beneficial effect:
1. the utility model is simple to operate, and the dress sample prescription just helps handling a large amount of samples.
2. the error of the utility model mensuration peanut single seed diffuse reflection spectrum is little, and favorable reproducibility can satisfy the requirement of peanut high-oil breeding.
3. on basis of the present utility model, can realize the single seeded oleaginousness of nondestructively measuring peanut.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is done detailed description further.
The VECTOR 22/N type ft-nir spectrometer that present embodiment uses German Brooker company to produce, instrument parameter is set to: the scanning spectrum district is 4000～10000cm
-1, scanning times is 64 times, resolution is 8cm
-1, be background with the white pottery porcelain.
As shown in Figure 1, the utility model is realized the collection of peanut single seed diffuse reflection near infrared spectrum.Vertical fixing has fixed support 1 on its base 10, the platform 8 that 2 geometrical clamps 3 is installed on fixed support 1 successively and can moves horizontally up and down, platform 8 is manually controlled by knob 9, the head that connects the solid probe 4 of light transmitting fiber 2 is installed on the fixed support 1 by geometrical clamp 3 vertically downward, on platform 8, white pottery porcelain 7 is installed over against solid probe 4, lay sample packing ring 6 on the white pottery porcelain 7, place single seed sample 5 in it.
Dress quadrat method: on moveable platform, lay the white pottery porcelain background of surface smoothing, seed is placed on it, below seed, can place sizeable packing ring, prevent that seed from rolling; The cotyledon back side of seed upwards.
Assay method: utilize platform to move up and down to make middle part, the seed cotyledon back side to contact with vertical solid probe head, the instruction spectrometer begins scanning, promptly finish scanning in 1 minute, obtain the diffuse reflection near infrared spectrum of sample, scan period does not move or vibrating example and solid probe.
As mentioned above, can realize the utility model preferably.
