Abstract
The invention provides an automatic continuous detection device for soil profile moisture content and a method. The automatic continuous detection device includes a detection sleeve and a detection instrument; the detection sleeve sleeves the detection instrument; the detection instrument includes a plug cover, a base, an automatic telescopic sleeve, an insulating connecting rod, a probe and a control unit; the base is fixed to the lower part of the plug cover, the automatic telescopic sleeve is arranged on the lower part of the base, the insulating connecting rod is connected to the lower part of the automatic telescopic sleeve, and the probe is arranged on the lower part of the insulating connecting rod; and the control unit is separately connected with the automatic telescoping sleeve and the probe. The detection sleeve based on the edge effect of an electric field is high in degree of integration, and a movable detection electrode is arranged in the detection sleeve to realize automatic detection of water content at different depths of the soil; the detection device is small in size and easy to carry, and the detection sleeve is in close contact with the soil and has small disturbance to crops and the soil; and a thread is manufactured on the outer surface of the detection sleeve, the detection sleeve can be manually or automatically inserted into the soil with the help ofelectric tools, the detection sleeve does not need to be embedded, can be used after being inserted and is convenient to use, and manpower is saved.
Description
technical field [0001] The invention belongs to the technical field of soil water content detection, and in particular relates to an automatic and continuous detection device and method for soil water content in a soil profile, which is mainly used for multi-layer automatic detection of moisture in different depths of the soil profile. Background technique [0002] Soil moisture changes with time and space, and the distribution characteristics, dynamic changes, and mutual circulation mechanisms of soil moisture are also significantly different under different soil types. Real-time and accurate measurement of water content at different depths of the soil profile can not only better understand the profile characteristics of soil moisture, but also has important significance for better understanding the water demand laws of different root crops, implementing precision irrigation and improving production efficiency. . [0003] The detection method of soil profile moisture mainl...
