Description
Technical field
The present invention relates to precision instrument technical field, be specifically related to the soil moisture detection of a kind of many sensing points
Instrument.
Background technology
Soil moisture is mainly derived from Atmospheric precipitation and irrigation water, additionally, subsoil water rises and water in air
The condensation of vapour is also the source of soil moisture.
Moisture is owing to being drawn by gravity, hollow billet gravitation, hydrone gravitation, grogs surface molecular in soil
The effect of the various power such as power, forms different types of moisture and reflects different character.
The content of soil hygroscopic water depends mainly on relative humidity and the soil texture of air.Air relative
Humidity is bigger, and the more, the content of soil hygroscopic water is the most the more for steam；The more viscous weight of the soil texture, surface area is more
Greatly, the moisture absorption water yield is the more.Additionally, the soil that humus content is many, the moisture absorption water yield is the most more.Hygroscopic moisture
Very big by the gravitation of grogs surface molecular, innermost layer can reach pF value 7.0, and outermost layer is pF value
4.5.So hygroscopic moisture is immovable, without dissolving power, plant can not absorb, and gravity can not make it move,
Only could move under the prerequisite being changed into vapourous water, therefore be also called tightly combined water, belong to nothing
Effect moisture.Its primary attachment power be molecular attraction and soil colloid granule with negative charge produce powerful
Captivation.
Soil moisture content has three important indicators.One is saturated soil water content, shows that this soil is most
Can contain how much water, now soil water potential is 0；Second is field capacity, is that saturated soil water content deducts
The retainable moisture of soil after gravitational water.Gravitational water substantially can not be absorbed and used by plants, now soil
The earth flow of water is-0.3 bar；3rd is wilting coefficient, soil the most retainable moisture when being plant wilt.This
Part water can not be absorbed and used by plants, and now soil water potential is-15 bars.
Therefore study the content of soil moisture, crops and ecological environment are had extremely important by quality
Effect.Unification is compared, it is impossible to enough the most random when of the detection of existing soil moisture survey meter
Regulate the degree of depth of its detection, it would be highly desirable to improve.
Summary of the invention
Present invention aims to defect and the deficiency of prior art, it is provided that a kind of simple in construction, set
Count the soil moisture survey meter of many sensing points reasonable, easy to use, it is possible to measure in soil different simultaneously
While the moisture of the degree of depth, additionally it is possible to as required, regulation probe location, the most convenient in time,
The scope of application is wider.
For achieving the above object, the technical solution used in the present invention is: it comprises detection device and sensor
Function control device；Described detection device is connected with sensor function controller by total transmission line；Institute
The detection device stated is made up of handle and probe；Described probe comprises a probe, No. two probes and No. three
It is evenly distributed with several probe on probe, and a probe, No. two probes and No. three probes；Described spy
Head is connected with total transmission line by respective transmission line respectively；A described probe, No. two spies
The top of pin and No. three probes is equipped with external screw thread；The inside of described handle is provided with several band internal thread hole,
Inside with internal thread hole is connected with a probe, No. two probes and No. three probes respectively；Described handle
It is provided with graduation mark layer.
Described handle is transparent plastic handle.
The inside of described sensor function controller is provided with information communication module, it is possible to the number that will collect
According to being transferred in mobile phone or computer, for immediately printing.
Externally threaded height on a described probe, No. two probes and No. three probes and band internal thread hole
Height identical.
The operation principle of the present invention: after entirety being inserted in soil, can be rotated at random probe as required,
For regulating the probe degree of depth in soil, the soil moisture content of different depth can be measured, conveniently use,
Can also specifically regulate its position in soil according to graduation mark simultaneously.
After using said structure, present invention have the beneficial effect that the soil of a kind of many sensing points of the present invention
Earth moisture survey meter, it is possible to simultaneously in measurement soil while the moisture of different depth, additionally it is possible to according to need
, in time regulation probe location, the most convenient, and the scope of application is wider, and have simple in construction,
The advantages such as reasonable, cost of manufacture is low are set.
