Description
Technical field
The present invention relates to seed scientific domain, particularly about a kind of Course of Corn Seed Germination top geotechnical survey method.
Background technology
Seed vitality refers under field condition widely, determines that seed is neatly emerged rapidly and grows up to the general name (McDonald, 1980) of normal seedling potential ability.In books such as " Testing Seed Vigor handbooks " that " the Seed Vigor Index handbook " edited and publish according to " principle of Testing Seed Vigor and method ", ISIT, AOSA are edited and publish described in related content, and in conjunction with our early-stage Study result, when seed sprouting emerges, a kind of strength is had to impel seed germination, young shoot upwards ejects, and this strength is called as Seed germinating ability.It is generally acknowledged, the Seed germinating ability that vigor is high is strong, and emergence rate is high, and the seed that vigor is low, then germinating capacity is weak, can not emerge and rot in soil.For corn seed, extended by mesocotyl in seed germination, coleorhiza breaks through soil layer, and then complete and emerge, coleorhiza break through soil layer this power form we be called the native power in top, it is a kind of important form of germinating capacity, therefore by comparing seed germination top soil power size to evaluate the size of seed vitality.Seed germination top soil power mensuration is the important content of the related scientific research work such as Testing Seed Vigor, in seed biological study, seed quality management, realizes having extremely important application prospect in improved variety and corresponding seed quality criteria etc.But measure at the action mode of this power at present and there is no good method.Traditional assay method only has lid paper method: get a soil box, sand is put into box, puts after planting, at the paper that casting bed upper cover one is harder.During seed sprouting, paper jack-up can be come by bud, then measures the height that paper is ejected by bud.Jack-up is highly larger, and namely power is larger, and seed vitality is also higher.But it is large that this method exists error, operation inconvenience, can only record the mean value of seed populations, native power is pushed up in the sprouting that cannot record every seed, also seldom adopts.
Summary of the invention
For the problems referred to above, the object of the invention is to provide a kind of Course of Corn Seed Germination top geotechnical survey method, can carry out Real-Time Monitoring, quantize to store, realize top geotechnical survey, meet seed vitality scale and detect needs Course of Corn Seed Germination top soil force signal.
For achieving the above object, the present invention is based on the characteristic of seed germination with the native power size variation in top, adopt Biological Strength sensing technology to carry out Real-Time Monitoring to the native force signal in top, quantize to store.The present invention is by the following technical solutions: a kind of Course of Corn Seed Germination top geotechnical survey method, and it comprises following operation: native force signal collection is pushed up by institute (1); (2) signal amplifies process; (3) filtering and noise reduction process; (4) live signal storage and reproduce; (5) signal quantization process; (6) Data Post.State in operation (1), seed germination bud scale tip contact pressure sensor probe starts to push up native force signal collection; In described operation (2), the output of pressure sensor is electrically connected signal amplifier to micro-force signal amplification process; In described operation (3), the output of signal amplifier is powered with source filter denoising; In described operation (4), the output of wave filter is electrically connected Holter recording box live signal storage and reproduce; In described operation (5), utilize the process of waveform quantization software, analog signal is turned data signal, and obtains quantized data; In described operation (6), require to screen quantized data, derive, store according to top geotechnical survey, the post processing such as analysis obtains top geotechnical survey result.
The invention has the beneficial effects as follows: based on the characteristic of seed germination with the native power size variation in top, adopt Biological Strength sensing technology to carry out Real-Time Monitoring to the native force signal in top, quantize to store, realize top geotechnical survey.The present invention can be widely used in Vigor of Zea mays L. Seeds detection.
Accompanying drawing explanation
Fig. 1 is operation process chart of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail.
As shown in Figure 1, the present invention is based on the characteristic of seed germination with the native power size variation in top, adopt Biological Strength sensing technology to carry out Real-Time Monitoring to the native force signal in top, quantize to store, realize top geotechnical survey.The Course of Corn Seed Germination top geotechnical survey method that the present invention relates to comprises the native force signal collection in top, signal amplifies the operations such as process, filtering and noise reduction process, live signal storage and reproduce, signal quantization process, Data Post.
The Course of Corn Seed Germination top geotechnical survey method embodiment that the present invention relates to is as follows.
(1) native force signal collection is pushed up: due in Course of Corn Seed Germination process, mesocotyl and coleoptile extend, top, coleoptile top soil stretches out bed surface, and along with the change of the native power size in top, Course of Corn Seed Germination top soil force signal acquisition target is the top soil power that coleoptile top produces.First pressure sensor is fixed on above germinating bed, the region that sensor probe perpendicular alignmnet coleoptile will stretch out, when coleoptile top and sensor probes contact start to push up native force signal collection.Wherein pressure sensor is pressure resistance type bridge-type, range: 0-30g; Full amplitude exports: >40mv/30g/5V; Precision: 1%; Supply voltage 5-9V; Output impedance: <3K Ω.
(2) signal amplifies process: the sprout time point top soil power size different at seed there are differences, and with many small-signals, the output of pressure sensor be electrically connected signal amplifier to small-signal carry out amplification process, reliably realize Differential Input, the first order adopts dc amplifier, and gain is less than 20 times; Adopt AC coupled between first and second grades, time constant is greater than 5s, ensures the undistorted amplification of small-signal.
(3) filtering and noise reduction process: be powered with source filter at the output of signal amplifier and the native force signal in top is processed, remove clutter.
(4) live signal storage and reproduce: change over time owing to pushing up native power size companion, and different cultivars seed or also there are differences with the top soil power of kind different batches seed, adopt Holter recording box can carry out live signal storage and reproduce to each seed top soil power.
(5) signal quantization process: utilize the process of waveform quantization software, analog signal is turned data signal, and obtains quantized data.
(6) Data Post: require to screen quantized data, derive, store according to top geotechnical survey, the post processing such as analysis obtains top geotechnical survey result.
In sum, the present invention is based on the characteristic of seed germination with the native power size variation in top, adopt Biological Strength sensing technology to carry out Real-Time Monitoring to the native force signal in top, quantize to store, realize top geotechnical survey.
