Description
Technical field
The present invention relates to precision agriculture advanced soil sensor-based system technical field, specifically one kind are based near infrared spectrum skill
The vehicle-mounted soil nutrient detection of art and automatic sampling apparatus.
Background technology
Precision agriculture is that Technical Revolution of Modern Science has an immense impact on down to agricultural the novel agricultural form gradually forming,
It is the modern agricultural production management technique that scientific and technological content is very high, integrated comprehensive is very strong.Traditional agricultural cultivating mode mainly according to
Carry out low level management by experience, although the use of chemical fertilizer, pesticide is greatly improved grain yield, blindly fertilising not only causes
Substantial amounts of waste, and bring serious soil, environmental pollution.Therefore, it is necessary to pay attention to soil nutrient e measurement technology, implement area
Domain Tree Precise Fertilization, fully excavates farmland production potentiality, rationally utilizes liquid manure resource, reduce environmental pollution, be greatly improved simultaneously
Agricultural output and quality.
At present, based on colorimetry principle, its precision can meet quantitative inspection to soil nutrient tacheometer on the market substantially
The requirement surveyed.But because soil constituent is complicated, the compound extraction of available nutrient is more difficult, for different types of soil, extract
Method is also otherwise varied.And the requirement due to extraction time, it is difficult to accomplish the real-time detection to Soil Nutrients in Farmland.With respect to than
Color method, ion-selective electrode detection soil nutrient do not need standard reagent, reagent paper etc., but the method typically can only detect water-soluble
Property available nutrient.
In recent years it is seen that light/near infrared spectroscopy, as a kind of analytical technology of green, due to its certainty of measurement height, divides
Analysis speed is fast, Multiple components are developed rapidly in a lot of association areas the advantages of can surveying simultaneously.According to soil diffusing reflection spectrum
Respective function relation between characteristic and constitutive property, the analytical tool based on visible ray/near-infrared diffusing reflection spectrum was at several seconds
Interior just the synchro measure of multiple components can be provided with data acquisition and analysis.Chinese patent cn101975764b discloses
A kind of multiband soil nitrogen detection means based on near-infrared spectrum technique and method, using seven single band near-infrared led
As active light source, by controlling the automatic or manual that motor achieves 7 wave band reflectivity datas to obtain it is adaptable to field
Between soil nitrogen real-time measurement.Chinese patent application 103091276a discloses a kind of soil nutrient sensor, using mems
Near infrared spectrometer is miniaturized by technology, precise treatment, integrated, develops a set of high accuracy, the portable and relatively low soil of energy consumption is supported
Sub-sensor.It is lossless that Chinese patent application cn101609042a discloses a kind of hand-held soil nutrient based near infrared spectrum
Measuring system, whole device weight, less than 1kg, can meet field soil nutrient and quickly measure needs.
To sum up, many portable, miniaturization soil sensings based on visible ray/near infrared spectrum are had at present both at home and abroad
Device, but measure after being both needed to first artificial or mechanical sampling, sampling is discontinuous with measurement process, and this especially should in large area in field
There is certain limitation used time.
Meanwhile, the measurement of soil nutrient content firstly the need of setting up calibration model, that is, collects representative soil-like
Product, as calibration samples collection, measure the near infrared spectrum of calibration samples collection, and using international law measurement nutrient data as standard
Content, sets up quantitative relationship using Multivariate Correction algorithm, i.e. calibration model.For unknown pedotheque, only need to be scanned it visible
Light/atlas of near infrared spectra, substitutes into corresponding calibration model, you can obtain accordingly each component content.The sample randomly choosing out is often
Cannot reflect the information of all samples well, and select representative calibration samples set pair positive model for school building general
Property and accuracy have considerable influence, also can reduce chemico-analytic workload simultaneously, be in NIR technology improve efficiency,
Reduce the important method of cost.
