Abstract
The invention discloses an automatic and rapid detection instrument for paddy rice field water nitrogen content, and belongs to detection instruments. A first electrode is sequentially communicated with a signal amplification integrated circuit, an analytical calculation integrated circuit and a data display through a first wire. One end of a salt bridge is inserted into a nitrogen standard solution cup. A second electrode is arranged in the nitrogen standard solution cup. The second electrode is communicated with the signal amplification integrated circuit through a second wire. Based on the concentration potential principle of soluble matter in a physical method, the instrument can detect the paddy rice field water nitrogen content in the paddy rice field, has the advantages of being small in size, low in manufacturing cost, convenient to use, easy to operate and high in detection speed, and is particularly suitable for being applied and popularized according to Chinese national conditions.
Description
Technical field
The invention belongs to detecting instrument, relates generally to a kind of instrument that can carry out detection fast automatically to nitrogen content in rice terrace paddy field water.
Background technology
At present, sampling chemical reagent spectrographic method is still adopted to the detection major part of rice terrace nitrogen content, there is many defects such as sense cycle is long, high to the requirement of testing staff's professional knowledge, chemical experiment detection complicated operation.In recent years, a kind of detecting instrument starts to survey application in inspection in rice terrace fertility, and this instrument is still in fact employing chemical analysis method, and it is expensive, and general Rice Cropping family is bought without economic strength and used, and is not suitable with China's national situation.Meanwhile, this instrument can not carry out the detection of rice field nitrogen content easily and efficiently at rice terrace scene.
Summary of the invention
The object of the invention is exactly for above-mentioned prior art Problems existing, and design provides a kind of rice terrace paddy field water nitrogen content automatic tacheometer, reaches cheap, simple to operate, easy to use, that detection speed is fast object.
The object of the invention is achieved in that the first electrode is communicated with signal amplification circuit, analytical calculation integrated circuit, data display equipment by the first wire successively; One end of salt bridge is inserted and is arranged in nitrogen standard solution cup, and in described nitrogen standard solution cup, arrange the second electrode, the second electrode is communicated with signal amplification circuit by the second wire, so far forms the automatic tacheometer of rice terrace paddy field water nitrogen content.
The invention adopts the concentration potential principle of solable matter in physical method, the first electrode integral of tacheometer and salt bridge one end is inserted in respectively in the paddy field water needing to detect, just can measures paddy field water nitrogen content in rice field fast and accurately how many.This tacheometer volume is little, and price is low, can at paddy field Site Detection, simple to operate, detection speed is fast, is conducive to generally planting family and carries out regular detection to rice terrace nitrogen fertility, timely grasp rice field fertility state, is Paddy fields, for crop growth creates good conditions accurately, in time at science.Especially China's national situation application is applicable to
Accompanying drawing explanation
Fig. 1 is rice terrace paddy field water nitrogen content automatic tacheometer general structure schematic diagram.
In figure, piece number illustrates:
1, the first electrode, 2, paddy field water, 3, the first wire, 4, signal amplification circuit, 5, analytical calculation integrated circuit, 6, data display equipment, 7, the second wire, 8, the second electrode, 9, nitrogen standard solution cup, 10, salt bridge.
Embodiment
Below in conjunction with accompanying drawing, the invention embodiment is described in detail.The automatic tacheometer of a kind of rice terrace paddy field water nitrogen content, the first electrode 1 is communicated with signal amplification circuit 4, analytical calculation integrated circuit 5, data display equipment 6 by the first wire 3 successively; One end of salt bridge 10 is inserted and is arranged in nitrogen standard solution cup 9, arranges the second electrode 8, second wire 7 and be communicated with signal amplification circuit 4 by second electrode 8 in described nitrogen standard solution cup 9.
When detecting operation use, the other end that is first electrode 1 is overall and salt bridge 10 is placed in paddy field water 2, nitrogen standard solution in nitrogen standard solution cup 9 is communicated with by salt bridge 10 with paddy field water 2 to be measured, processed by signal amplification circuit 4, analytical calculation integrated circuit 5 by electric potential difference, calculate nitrogen content in paddy field water 2, result is shown, for plantation family provides fertilising foundation by data display equipment 6.
