介绍了一种农田土壤含水率与坚实度快速信息采集系统。本系统包括土壤介电传感器、圆锥指数传感器及深度传感器,可以快速、同步、实时地获得0~500mm范围内土壤剖面含水率与圆锥指数信息。同时,本系统还结合了GPS和GIS技术,实现了土壤参数的空间分析,可以更方便地把系统应用于农田信息管理。本系统为实现土壤水分和坚实度的同步测量搭建了一个智能化的试验平台,并且在与德国波恩大学农业工程研究所的合作中成功地应用于田间测量。
A quick measuring system for soil water content and soil hardness was introduced in this paper. The system consists of dielectric sensor, pressure sensor and depth sensor, which can measure soil water content and soil hardness from 0mm to 500mm on profile simultaneously. The system is also integrated with GPS and GIS. It is easy to analyze the spatial distributions of soil parameters. The system could be applied to farm information management conveniently.
