Description
Technical field
The utility model belongs to the improvement of soil salinity and alkalinity detector structure, particularly agricultural soil saline and alkaline detector.
Background technology
Pocket in addition except the laboratory on the market with saline and alkaline measuring instrument, it is made up of a handle end and a host side, respectively can the measured soil conductivity, soil acidity or alkalinity, measurement temperature, all with these data presentation on liquid crystal display, and can write down and measure the place, data are imported computer with USB, but for Chinese farmers and impracticable, the peasant is not the expert, the peasant only wonders the height of this saline and alkaline degree in sheet ground, whether be fit to the plant that kind is thought oneself in plantation, whether need to improve the soil.
Document 1: the W.E.T soil moisture, temperature, the conductance instrument that originate in the YSI of U.S. manufacturer have mainly been studied soil moisture content, conductivity, three parameter measurements of temperature; Purposes: field portable formula soil moisture content, conductivity, three parameter speed of temperature are surveyed; Principle: FDR principle, measured soil water cut, conductivity, three parameters of temperature simultaneously; System forms: main frame (but memory-type meter reading): can store 2100 reading sensors: measured soil water cut, conductivity, three parameters of temperature; Characteristics:
Portable, easy to carry;
Measure rapidly, the response time is short;
Can demarcate at Different Soil, reach more high measurement accuracy;
Select the medium timing signal of specific type, can measure media such as fiber, coal ash;
Data can be the ASCII fromat data of standard by software download;
Meter reading directly shows water cut, temperature and conductivity.
Document 2: the soil salt determining instrument mainly can be measured soil conductivity, directly on the soil salinity sensor from be embedded in soil, by a circular dial scale instrumentation amount soil salinity.Have the steady temperature calibration function, automatically with temperature correction on 25 degrees centigrade standard temperature.Electricity is led scope 1.5-40mmhos/cm.Salt bridge is a kind of easy instrument, and it can be used for following the tracks of the dynamic change of salinity in the soil and many disturbed soils continuously.Probe adopts the specific inductive capacity and the conductivity of a kind of special integrated circuit measured soil of IMAG exploitation, converts the conductivity of the soil liquid then to.The design of probe is guaranteed need not to demarcate and make the exposure level of reading and soil and probe irrelevant at specific soil.The particular design of tips of probes promptly is easy to insert soil, again the specific inductive capacity of energy measurement measuring point and conductivity.These characteristics has been guaranteed measurement, the calculation stability, reliable of conductivity.Can handle from the data of popping one's head in the software that probe provides, calculate also demonstration soil conductivity, and with data storage hereof.The U.S. has announced in the solonchak laboratory crops tolerance of salinity database.Though this database is to be unit (dS.m-1) with saturated conductivity, the reading of Sigma Probe probe can directly compare with it, provides a clear and definite indication, and the possible underproduction that the growing environment owing to crop causes be described.Sigma Probe also is the priceless treasure of salinity influence in prospecting field variability and the irrigation water.
In sum, the instrument of selling on the market belongs to external product mostly, and language is incompatible, use difficulty, especially price height, and the instrument of this real estate of China, and volume is big, uses complexity, and price is more expensive, is not suitable for peasant's use.W.E.T soil moisture, temperature, conductance instrument principle are the FDR principles, while measured soil water cut, conductivity, three parameters of temperature, but these data parameters are specialty too, can not satisfy the peasant equally, still not have directly to tell simply the peasant soil of how suiting measures to local conditions to administer.
The utility model content
The purpose of this utility model is to provide a kind of agricultural soil saline and alkaline detector, it is rational in infrastructure, compactness is utilized multimeter principle measured soil saline and alkaline, convenient common peasant is by setting the button selection and selecting crop by the program and the data-carrier store that are arranged in the single-chip microcomputer, the energy measurement soil salt content, show soil salinization kind and degree, can select three kinds of basic crops simultaneously, point out out the irrigation suggestion in reasonable arable land according to the soil salinization intensity, simple and practical, also convenient the connection, practical, cost is low, simple to operate, intuitive display is succinct, is fit to common farmers' family and buys use.
The purpose of this utility model is achieved in that a kind of agricultural soil saline and alkaline detector; the LCDs that is positioned at casing is arranged on the back side of glass protection screen; be connected with the single-chip microcomputer in being built in casing; being arranged on power input interface on the casing matches with direct supply and is connected; power input interface is connected by lead and microcontroller power supply port; the power switch that is arranged on the casing is serially connected on the circuit that connects between microcontroller power supply port and the power input interface; cooperate in the socket that is plugged on the casing respectively by plug with its other end of lead that a pair of probe is connected respectively; this socket is connected with the input end of single-chip microcomputer by lead; the setting button is being set on the casing; set button and be connected, and match with LCDs by single-chip microcomputer and to be connected by lead and single-chip microcomputer.
The utility model is simple to operate, compare with previous similarly soil salinity and alkalinity tester, it cooperates (about being correlated with of various soil typess) data and program storage in the single-chip microcomputer to demonstrate corresponding Chinesizing information on LCDs by the additional setting button that is provided with, instruct the peasant should cultivate the crop of which kind, therefore, the utility model is rational in infrastructure, utilize multimeter principle measured soil saline and alkaline, convenient common peasant is by setting button and select and by being arranged at program in the single-chip microcomputer and data-carrier store and according to (Chinesizing) display message transformation soil of its corresponding prompting, suit measures to local conditions to select crop, the energy measurement soil salt content, show soil salinization kind and degree, can select three kinds of basic crops simultaneously, point out out the irrigation suggestion in reasonable arable land according to the soil salinization intensity, accomplish simple and practical, cost is low, and is easy to use, simple to operate, intuitive display is succinct, is particularly suitable for common farmers' family and buys use.
