Water consumption in agriculture is impossible without considering relations between water, soil and plant. In this regard, there are various models and developed software in order to evaluate relation between soil, water and crop growth stages. These models can be used for irrigation planning if properly optimized and applied. AquaCrop is one of the known crop models, which was developed by the Food and Agriculture Organization of the United Nations. In order to optimize this model for crop production and irrigation management, an experiment was developed in a hydroponic cucumber greenhouse. Various parameters including water consumption volume, crop yield and leaf area index were measured during a season. A fuzzy control system was utilized for controlling temperature, relative humidity, planting bed moisture, light intensity and carbon dioxide values. The main purpose of designing a control system in the greenhouse is to achieve the desired values of temperature and relative humidity. In this model, evapotranspiration, irrigation requirements and crop yield were simulated. The results show that the AquaCrop model can estimate evapotranspiration with the least error in the greenhouse environment, which is controlled by a fuzzy controller. Also the system has estimated the crop yield and biomass of the product with a good degree of precision and it may support crop production in a greenhouse, including crop management and environmental control.

温室栽培黄瓜AquaCrop模型评价

不考虑水、土壤和植物之间的关系，农业用水是不可能的。在这方面，有各种模型和开发的软件来评估土壤、水和作物生长阶段之间的关系。如果适当优化和应用，这些模型可用于灌溉规划。AquaCrop 是联合国粮食及农业组织开发的已知作物模型之一。为了优化这种作物生产和灌溉管理模型，在水培黄瓜温室中开展了一项实验。在一个季节测量了各种参数，包括耗水量、作物产量和叶面积指数。模糊控制系统用于控制温度、相对湿度、种植床湿度、光照强度和二氧化碳值。在温室中设计控制系统的主要目的是达到所需的温度和相对湿度值。在该模型中，模拟了蒸散量、灌溉需求和作物产量。结果表明，AquaCrop 模型可以在模糊控制器控制的温室环境中以最小的误差估计蒸散量。此外，该系统还以良好的精度估算了产品的作物产量和生物量，它可以支持温室中的作物生产，包括作物管理和环境控制。灌溉需求和作物产量进行了模拟。结果表明，AquaCrop 模型可以在模糊控制器控制的温室环境中以最小的误差估计蒸散量。此外，该系统还以良好的精度估算了产品的作物产量和生物量，它可以支持温室中的作物生产，包括作物管理和环境控制。灌溉需求和作物产量进行了模拟。结果表明，AquaCrop 模型可以在模糊控制器控制的温室环境中以最小的误差估计蒸散量。此外，该系统还以良好的精度估算了产品的作物产量和生物量，它可以支持温室中的作物生产，包括作物管理和环境控制。
