Abstract
A soil humidity meter for field planting comprises a stainless steel tubular shell, an end cover is arranged at the top end of the shell and used for sealing, a center hole is formed in the center of an end cover at the lower end, a fiber tube bundle is inserted into the center hole, the upper end of the fiber tube bundle stretches into the shell, and the lower end of the fiber tube bundle stretches out of the shell; a first humidity induction electrode is arranged below the end cover at the top end of the shell, a second humidity induction electrode is arranged 20-30 mm below the first humidity induction electrode, a semipermeable membrane layer is attached to the bottom face of the second humidity induction electrode, the fiber tube bundle stretching into the shell is sleeved with a semipermeable membrane sleeve, the top end of the semipermeable membrane sleeve is connected with the semipermeable membrane layer in a sealed mode, and a cavity formed by the semipermeable membrane layer, the semipermeable membrane sleeve and the inner wall of the shell in a defined mode is filled with a salt ion solution. The soil humidity meter is simple in structure, long in service life and high in detection accuracy.
Description
Technical field
The present invention relates to a kind of tensiometer.
Background technology
Field planting environment measuring predominantly detects the secretaries such as the temperature and humidity of soil, illumination, and soil moisture determines the water supply situation of crops.Soil moisture is too low, forms soil drought, and photosynthesis can not be normally carried out, and reduces the yield and quality of crop；Serious water shortage causes crop wilting and dead.Soil moisture is too high, deteriorates soil aeration, affects the activity of soil microorganism, make the vital movements such as the breathing of crop root, growth hindered, thus affect the normal growth of crop field upper part, cause excessive growth, lodging, disease to grow.
Summary of the invention
The present invention is directed to prior art, it is provided that a kind of simple in construction, service life is long, the field planting tensiometer that accuracy of detection is high.
For realizing the object of the invention, provide techniques below scheme: a kind of field planting tensiometer, it is characterized in that including rustless steel tubular shell, housing tip arranges end cap seal, lower end end cap central offers centre bore, centre bore is inserted into fiber tube bank, fiber tube bank upper end is stretched in housing, lower end is stretched out outside housing, a humidity inductive electrode it is provided with below housing tip end cap, a number humidity inductive base part interval 20 ~ 30mm is provided with No. two humidity inductive electrodes, No. two humidity inductive electrode bottom surfaces are covered with semipermeable membrane floor, stretch into and be arranged with semi-transparent Membrane cover in the tube bank of the fiber in housing, semi-transparent Membrane cover top is tightly connected with semipermeable membrane layer, semipermeable membrane layer, it is filled with salt ion solution in the cavity that semi-transparent Membrane cover and inner walls surround.Described semipermeable membrane is that the moisture in salt ion solution can flow freely, but the semipermeable membrane that salt ion cannot penetrate.
As preferably, a humidity inductive electrode cable connects microprocessor, and microprocessor connects display screen.
As preferably, the housing bared end of fiber tube bank is arranged with rustless steel needle tubing, and stainless pin tube-surface offers permeable hole.
The method have the benefit that simple in construction, it is simple to make, certainty of measurement is high, the problem effectively overcoming the soil thermometer poor accuracy of prior art.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
