作物 -土壤 -气候模拟是确定每次灌溉的时机选择和灌溉水量的主要工具。它有助于规划、设计和运行有效的灌溉系统 ,也有助于改善灌区的水管理系统。为进行本研究 ,收集了印度奥里萨邦巴里巴特纳灌区的气象资料 ,该灌区主要种植水稻、马铃薯和花生。根据作物生长过程资料 ,计算其日需水量。利用日降雨资料和土壤含水量平衡表法 ,计算出有效雨量和这三种作物的灌溉需水量 ,从而编制出作物的灌溉计划
Crop-soil-climate simulations are the main tools used to determine the timing of each irrigation and the volume of irrigation water. It helps to plan, design and operate effective irrigation systems and also helps to improve water management systems in irrigation districts. For the purpose of this study, meteorological data were collected from the Bari Batna irrigation area in Orissa, India, where rice, potatoes and peanuts are mainly grown. According to the crop growth process data, calculate the daily water demand. Using the daily rainfall data and the soil moisture balance table method, the effective rainfall and irrigation water requirements of these three crops were calculated to prepare the irrigation plan of the crops
