Abstract

The invention discloses a moisture sensor and a surface soil parameter acquisition device, and relates to the technical field of soil information acquisition. Especially, the moisture sensor includes two sheet electrodes and two signal lines; the two signal lines are connected to the two electrodes in one-to-one correspondence; and the two electrodes are arranged in parallel. Through arrangement on the structure of the moisture sensor, the invention realizes acquisition of moisture content of surface soil directly contacted with the atmosphere and can effectively provide digitalized information for field soil surface evaporation and water and soil conservation.

Description

technical field [0001] The invention relates to the technical field of soil information collection, in particular to a moisture sensor and a surface soil parameter collection device. Background technique [0002] As an important environmental factor and component of the ecosystem, soil directly participates in the material cycle and energy cycle of the ecosystem. Specifically, soil is a natural resource and means of production that provides essential water and nutrients for plant growth, thereby affecting animal growth and activities. In order to better guide agricultural production and promote the material and energy cycle of nature, the modern information society puts forward new requirements for soil environment monitoring. [0003] Soil moisture is the most active factor in soil fertility. It can affect soil structure and soil tillability, control soil respiration intensity, and change the composition and distribution of soil gas, heat and nutrients. The existing soil ...
