Description

Soil humidity detector for agricultural meteorology Technical Field The utility model relates to the technical field of agricultural equipment, in particular to a soil humidity detector for agricultural meteorology. Background Soil moisture detection is a crucial basic task in the field of modern agricultural production and meteorological research. The soil humidity directly influences the growth and development of crops, the occurrence of diseases and insect pests and the stability of an agricultural ecological system, the soil humidity data is accurately and efficiently obtained, the soil humidity sensor has key significance for scientific irrigation, accurate fertilization, agricultural meteorological disaster early warning and the like, and the soil humidity sensor is used as core equipment for realizing the functions, and has wide attention on performance and technical level. Currently, most of the common soil humidity detectors in the market adopt a probe type structure, and the physical parameters such as dielectric constant and resistance of the soil are sensed by a sensor by inserting a probe into the soil, so that the soil humidity value is obtained through conversion. The operation purpose of the detector is to provide real-time soil humidity data for agricultural production and assist farmers to make irrigation decisions so as to achieve the technical effects of saving water, increasing yield and improving agricultural production efficiency. However, the prior art has a plurality of defects that firstly, in the process of inserting the traditional probe type detector into soil, if the traditional probe type detector encounters hard soil or underground barriers, the conditions of bending and breaking of the probe and the like are easy to occur, the detection accuracy and the service life of equipment are influenced, secondly, most of the detectors lack of effective design for self protection, in the long-term outdoor use process, the traditional probe type detector is easily worn and corroded by acid and alkali substances, microorganisms, mechanical friction and other factors in the soil, the stability of the equipment is easy to be reduced, thirdly, the detection range and the depth of the traditional probe type detector are limited, and the diversified requirements of different crops on soil humidity detection at different depths in different growth stages are difficult to meet. Based on the above needs, there is a need to design a soil moisture detector for agricultural meteorology with stable structure and accurate detection Disclosure of Invention In order to solve part or all of the technical problems, the application provides a soil humidity detector for agricultural meteorology, which can monitor soil with different depths and can effectively protect the technical advantages of a probe.
