Technical field

The utility model relates to the technical field measuring soil water content, in particular to a kind of device measuring soil water content for original position layering.

Background technology

Soil moisture is the direct sources of plant moisture, and the nutritive substances such as the moisture in plant absorption soil, organic matter grow. Meanwhile, the number of soil water content decides again the quality of the upgrowth situation of plant. Therefore, measured soil moisture has important actual meaning. For clear and definite crop law of needing the water and then scientific and reasonable guidance are irrigated, it is necessary to soil moisture content is studied.

At present, the method for conventional measured soil moisture content mainly contains: oven drying method of weighing, NEUTRON METHOD, gamma ray method, soil moisture sensor method, time domain reflection method. The method measured for soil water content above respectively has relative merits. Common oven drying method of weighing needs to be dried by soil every time, and workload is big and wastes the energy, although additive method is simple to operate, but equipment price is expensive, and fund input amount is big. And, the research that current various method measures soil water content for layering is deficienter.

At present, having of relevant measured soil water ratio application Chinese patent: No. CN200910235449.5 " multiple spot soil moisture sensor and utilize its method carrying out soil moisture measurement ", No. CN201110392448.9 " soil moisture detection method and equipment ", No. CN200610135090.0 " a kind of method for measuring soil moisture and modifying device thereof ", No. CN201010252503.X " the remote sensing quantitative inversion method of soil moisture feed rate " etc., these large-scale soil water content determinators have good measurement effect, but apparatus expensive, fund input amount is big, support equipment is complicated, its application receives certain restriction.
