Description
Technical field
The utility model belongs to the technology that soil water content is measured in fields such as pedology, agronomy, forestry and ecology, is specially a kind of modifying device that is used to measure the space-time heterogeneity (the space-time heterogeneity comprises special heterogeneity and time heterogeneity) of soil moisture.
Background technology
Moisture is an important component part in the soil, and it not only affects soil physical, is restricting the activity of dissolving, transfer and the microorganism of nutrient in the soil and solvent, and is a key factor that constitutes soil fertility and soil property.Therefore, accurately determine soil moisture, all have great significance in theory with on producing.Oven drying method is the most frequently used a kind of method, also is the classical way of determining soil moisture, and is simple, and enough precision are arranged; But oven drying method wastes time and energy, can not the original position duplicate measurements.And the research of current soil moisture more and more depends on the progress of means of testing.How fast the research of means of testing mainly concentrate on, measure reliably, routinely soil moisture content.In order to change this situation, people have successively worked out many fixed points and assay method easily, these methods have: depressimeter (tensiometer) method, instrument weight method, gamma-rays transmission beam method, radiant heat method, electric-resistivity method, capacitance method, remote sensing technology method, Neutron Moisture instrument method and TDR (time-domain reflectomer, Time Domaio Reflectometer) method etc.Yet these measuring methods always exist such or such deficiency in actual applications, mainly show: instrument cost (price), precision, be convenient for carrying degree, finding speed and operation complexity etc.Can not accurately measure the upper soll layer water cut as the Neutron Moisture instrument, also be subjected to the influence of soil types, structure, density, temperature and salt content, long-term measurement result less stable; Remote sensing monitoring can be realized the real-time dynamic monitoring of large tracts of land soil moisture, but because the spatiality of soil moisture is bigger, accurately measure soil moisture and be still global difficult point, many theory and technologies still among inquiring into, improve problems such as the pragmatic effect of kimonos as precision.
At present, Neutron Moisture instrument that people generally acknowledge and TDR are more satisfactory methods, and wherein the precision measured than Neutron Moisture instrument of the water cut of the upper soll layer measured of TDR instrument is much higher.And comprise the tubular soil moisture instrument of several series based on the assay method of TDR principle, as: TRIME EZ/EZC, TRIMEIT/ITC, TRIME T3, TRIME P3, but their emphasis differences, so that usable range, comfort level and cost exist than big-difference.Wherein TRIVE EZ/EZC, IT/ITC type soil moisture instrument can only measured soil surface water cut or are measured the water cut of different depth by shoveling earth section.And TRIME T3 type soil moisture instrument can be measured the soil profile water cut in the 3m through after improvement and having the long TECANAT plastic tube (cost height) of 3m.But relative TRIME EZ/EZC, IT/ITC type soil moisture instrument, TRIME T3 type soil moisture instrument price is higher, and measures face of land water cut inconvenience.Therefore, design a kind ofly be convenient for carrying, price is low, and can conveniently measure face of land water cut, the device of the rapid and accurate determination different depth soil moisture content of fixing a point for a long time again obviously is very necessary and have realistic meaning.
