作者利用PC微机建立了土壤诊断系统。本系统包括土壤剖面、土壤理化性质数据文件,还可根据需要装入土壤柱状断面、三相分布、pF-土壤水分曲线、诊断和建议以及雷达图等数据文件。因此可用于综合诊断土壤,并可向农民推荐适用的土壤改良方法和肥料施用技术。此外,所建立的土壤管理子系统,可用来进行土壤诊断以确定本地的土壤管理措施和适合作物生长的条件。土壤调查点的位置是以大比例尺地图为底图(图中的小块土地可被识别),贮存在图象文件中,并根据计算机显示屏上的X-Y轴坐标记录下来。通过上述农场图的利用,可充分了解土壤特性及其与作物生长的关系。
The author uses PC microcomputer to establish a soil diagnosis system. The system includes data files of soil profile and soil physical and chemical properties. Data files such as columnar section, three-phase distribution, pF-soil moisture curve, diagnosis and suggestion, and radar chart can also be installed as required. It can therefore be used for integrated diagnosis of soil and recommend suitable soil improvement methods and fertilizer application techniques to farmers. In addition, soil management subsystems have been established to conduct soil diagnostics to determine local soil management practices and conditions suitable for crop growth. The location of the soil survey point is based on a large scale map (small pieces of land in the figure can be identified), stored in an image file, and recorded on the X-Y axis of the computer screen. Through the use of the above farm map, we can fully understand the characteristics of soil and its relationship with crop growth.
