用来确定灌水频度和灌水量的灌溉计划是最佳用水所必需，同时也是获得最高产量和农田收益所必需的。本文介绍了计算机辅助的蒙特利尔大学自动灌溉计算系统，即ＡＩＳＳＵＭ（ＡｕｔｏｍａｔｉｃＩｒｉｇａｔｉｏｎＳｃｈｅｄｕｌｉｎｇＳｙｓｔｅｍｏｆｔｈｅＵｎｉｖｅｒｓｉｔｙｏｆＭｏｎｔｒｅａｌ）的主要原理和应用。ＡＩＳＳＵＭ获得用户好评，它有优化水利用，增加作物产量的潜力。ＡＩＳＳＵＭ根据水平衡原理制定灌溉计划。必需的天气、土壤资料通过太阳能驱动并且可移动的微气象系统（ＳＥＷＢＳ）收集。作物蒸散ＥＴ用已定型的软件包ＥＤＡ计算。灌溉计划通过软件包ＡＩＳ·ＩＲＲＩＧ执行。文中列举了ＡＩＳＳＵＭ用于特立尼达的黄秋葵（Ｏｋｒａ）作物和魁北克的木莓地的试验结果。另外提供了灌溉计划的实时估计。ＡＩＳＳＵＭ给出较循环法更为优良的结果。
Irrigation programs to determine the frequency and amount of irrigation are necessary for optimum water use and are necessary to obtain the highest yields and farm yields. This paper presents a computer-aided Montreal University automatic irrigation computing system, the main principle and application of AISSUM (AutomaticIscheduling System of the University of Montreal). AISSUM is well received by users and has the potential to optimize water use and increase crop yields. AISSUM draws up irrigation plans based on the principle of water balance. Required weather, soil information is collected by the solar powered and mobile micro-weather system (SEWBS). Crop evapotranspiration (ET) is calculated using the established software package EDA. Irrigation plans are implemented through the software package AIS · IRRIG. The article lists the results of AISSUM’s trial of Okra crops in Trinidad and quince raspberries in Québec. In addition, real-time estimates of irrigation plans are provided. AISSUM gives more excellent results than the circulation method.
