Abstract
The invention provides an instrument for automatically and rapidly detecting the potassium content in paddy field water, and belongs to detecting instruments. A first wire connects a first electrode with a signal amplifying integrated circuit, an analyzing and calculating integrated circuit and a data display in sequence, one end of a salt bridge is installed in a potassium standard solution beaker in an inserted mode, a second electrode is arranged in the potassium standard solution beaker, and a second wire connects the second electrode with the signal amplifying integrated circuit. According to the instrument for automatically and rapidly detecting the potassium content in the paddy field water, a concentration potential principle of soluble substances in a physical method is adopted, the potassium content in the paddy field water can be detected at the scene of a paddy field, and the instrument has the advantages of being small in instrument size, low in manufacturing cost, convenient to use, easy to operate, high in detecting speed and particularly suitable for application and popularization for the situation of China.
Description
Technical field
The invention belongs to detecting instrument, relates generally to a kind of instrument that potassium content in rice terrace paddy field water can carry out quickly detection automatically.
Background technology
At present, the detection major part of rice terrace potassium content is still adopted sampling chemical reagent spectra methods, there is many defects such as detection cycle length, testing staff's Professional knowledge requirement is high, chemical experiment detection complicated operation. In recent years, a kind of detecting instrument begins at rice terrace fertility and surveys application in inspection, and this instrument is substantially still 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 potassium content easily and efficiently at rice terrace scene.
Summary of the invention
The purpose of the invention is aiming at above-mentioned prior art Problems existing, and design provides a kind of rice terrace automatic tacheometer of paddy field water potassium content, reach cheap, simple to operate, easy to use, detect fireballing purpose.
The purpose of the invention is achieved in that the first electrode is connected by the first wire successively with signal amplification circuit, analytical calculation integrated circuit, data display equipment; One end of salt bridge is inserted and is arranged in potassium standard solution cup, arranges the second electrode in described potassium standard solution cup, and the second electrode is connected by the second wire with signal amplification circuit, so far constitutes the rice terrace automatic tacheometer of paddy field water potassium content.
The invention adopts the concentration potential principle of solable matter in physical method, is respectively inserted in the paddy field water needing detection in overall for the first electrode of tacheometer and salt bridge one end, just can measure paddy field water potassium 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 plantation family that rice terrace potash fertilizer power is carried out regular detection, grasp in time rice field fertility state, science, be Paddy fields accurately, in time, create good conditions for crop growth. It is especially suitable for China's national situation application

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention embodiment is described in detail. A kind of rice terrace automatic tacheometer of paddy field water potassium content, the first electrode 1 is connected by the first wire 3 successively with signal amplification circuit 4, analytical calculation integrated circuit 5, data display equipment 6; One end of salt bridge 10 is inserted and is arranged in potassium standard solution cup 9, arranges the second electrode 8 in described potassium standard solution cup 9, and the second electrode 8 is connected by the second wire 7 with signal amplification circuit 4.
When detection operation uses, first electrode 1 is overall and salt bridge 10 the other end is placed in paddy field water 2, potassium standard solution in potassium standard solution cup 9 is connected 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 potassium content in paddy field water 2, shown result by data display equipment 6, provide fertilising foundation for plantation family.
