Abstract

Disclosed are a device for testing an EC value of soil and a use method therefor. The device comprises an EC sensor assembly and a solution test container assembly; the EC sensor assembly comprises an EC sensor, a PVC casing (5) and a reducing sleeve (4), the EC sensor comprising a sensor probe (1), a sensor cable (2) and a cable fastening joint (3); the solution test container assembly comprises an outer container (21), an inner container (22), a plastic corrugated pipe (23), a PVC fixed pipe (24), a filter sponge (25), a clamping joint (26) and resin glue; the EC sensor assembly is arranged in the clamping joint (26); and the sensor probe (1) is located in a space for containing a solution formed between the outer container (21) and the inner container (22). The device and the use method therefor enable the EC sensor to detect an ion concentration of fertilizer in tested soil, and enable the sensor probe (1) to monitor a change condition of the ion concentration of the fertilizer in the soil in a drop irrigation process in real time.

Description

technical field [0001] The invention relates to a test device, in particular to a soil EC value test device and a use method thereof. Background technique [0002] At present, the known EC value measurement method in the field of agricultural irrigation control systems is to directly measure the ion concentration of the sampled irrigation solution with a hand-held sensor, so that the measured value is only the measurement result before the crops are irrigated. Usually, agricultural technicians use The data obtained by this measurement method is used as the basis for judging whether the ion concentration of the soil fertilizer is up to standard. However, the parameters obtained by using this inaccurate measurement method cannot truly reflect the concentration of fertilizer ions in the substrate (soil) after irrigation, which may cause adverse effects on the growth of crops. However, in the prior art, there is no properly designed soil EC value testing device to measure the r...
