Abstract
The utility model relates to a soil moisture content detector belonging to a detection device; the soil moisture content detector comprises a probe, a current meter and a copper rod; the probe and one end of the copper rod are fixed on an insulator to form a pen shape; the current meter is fixed at the other end of the copper rod; and the probe and the copper rod are respectively connected with the current meter. The probe is made of zinc. The soil moisture content detector has a compact structure and convenience for use; and the soil moisture content detector capable of directly performing humidity test is more accurate in measurement, lower in cost, and suitable for popularization.
Description
Technical field
The utility model belongs to pick-up unit, particularly relates to a kind of soil moisture content detector.
Background technology
The water supply situation of soil moisture decision crops.Soil moisture is low excessively, forms soil drought, and effect photosynthesis can not normally carry out, and reduces the yield and quality of crop; Serious water shortage causes crop wilting and dead.Soil moisture is too high, worsens soil aeration, influences the activity of soil microorganism, and the vital movements such as breathing, growth of crop root are hindered, thereby influences the normal growth on crop field top, causes that excessive growth, lodging, disease are grown etc.What of soil moisture also influence field tillage control measure and seeding quality, and influence the height of the soil moisture.Existing soil moisture measurement and control instrument roughly divides two kinds, and a kind of is portable, and it is in light weight, and price is low, and it is convenient to measure, but measuring error is big, and precision is low, uses inconvenient operation, can not satisfy the needs that soil moisture multimetering and fixed point are irrigated.Another kind is to have the decision system device, but its complex structure costs an arm and a leg, and is unfavorable for applying.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, and a kind of soil moisture content detector is provided.
Soil moisture content detector of the present utility model is to be made of probe, reometer and copper bar, and an end of described probe and copper bar all is fixed on and forms lip pencil on the insulator, has fixed reometer at the other end of copper bar, and probe all is connected with reometer with the copper bar.
As further improvement of the utility model, described probe is to be made by zinc.
As further improvement of the utility model, the outside of copper bar be provided with housing, with reometer outside housing be fixed as one.
The utility model soil moisture content detector compact conformation, easy to use can directly carry out the soil moisture content detector of humidity measurement, and it is more accurate to measure, and price is comparatively cheap, is suitable for popularization.
Description of drawings
Fig. 1 is the structural representation of the utility model soil moisture content detector;
Fig. 2 is the circuit theory diagrams of the utility model soil moisture content detector.
Embodiment
Soil moisture content detector of the present utility model as shown in Figure 1, is to be made of probe, reometer and copper bar.Probe 1 and an end of copper bar 2 all are fixed on the insulator 3 and form lip pencil, have fixed reometer 4 at the other end of copper bar 2, and probe 1 all is connected with reometer 4 with copper bar 2.Described probe 4 is to be made by zinc.
In the said structure, zinc probe, copper bar and reometer essence constitute one and open wide circuit, zinc probe and copper bar are two electrodes of circuit, after in zinc is popped one's head in related copper bar insertion soil, it is electrolytic solution that soil promptly becomes conducting medium, humidity difference in the soil causes the electric current of closed circuit to produce strong and weak the variation, indicates the humidity situation of soil by the numerical value change of reometer.Although it is very weak that the soil electric current is generally 0 ~ 500MA electric current, the internal resistance setting of reometer is close to zero, reometer is still fairly obvious to the variation indication of humidity in the soil.So the soil electric current that electrode records is big more, and the electric current that flows through the reometer gauge outfit is just big more, that is its humidity is big more.
For guard electrode and make soil moisture tester overall appearance; described zinc probe and described copper bar are outside equipped with containment vessel; to play protection and effect attractive in appearance; but must part zinc probe and copper bar be exposed; after zinc probe and copper bar insert soil simultaneously, to form closed circuit; the conducting reometer, indication soil moisture.
Claims (3)
1. soil moisture content detector, be to constitute by probe, reometer and copper bar, an end that it is characterized in that probe (1) and copper bar (2) all is fixed on upward formation lip pencil of insulator (3), fixed reometer (4) at the other end of copper bar (2), probe (1) all is connected with reometer (4) with copper bar (2).
2. soil moisture content detector as claimed in claim 1 is characterized in that described probe (4) is to be made by zinc.
3. soil moisture content detector as claimed in claim 1 or 2, it is characterized in that the outside of copper bar (2) be provided with housing (5), with reometer (4) outside housing (6) be fixed as one.
