土壤墒情是反映一地土壤含水量多少的主要指标,墒情的好坏直接影响着农作物的生长。对于土壤墒情的计算和编报,曲沃县气象站经历了从完全的由人工查算计算编报,到用Basic语言编程计算编报,再到以后的Excel表格计算几个阶段。但这几种方法要么是计算量大,要么是界面不友好不易控制,要么是对操作计算机人员水平要求过高,稍不留心可能造成计算错误等多种不便。应用VFP语言可容易的编出具有Windows风格的程序,既方便操作,又能保证计算的精确度。
Soil moisture content is a major indicator of how much soil moisture content in a place, the quality of soil moisture directly affects the growth of crops. For the calculation and compilation of soil moisture, Quwo County weather station has gone through several stages from complete manual calculation and compilation to basic language programming and compilation to later Excel spreadsheet calculation. However, these methods are either computationally intensive or not easy to control because of the unfriendliness of the interface, or they are inconveniences of requiring computer operators to operate too much or not paying attention to errors in calculation. Application VFP language can be easily programmed with Windows-style programs, both for easy operation, but also to ensure the accuracy of the calculation.
