烤烟实时灌溉预报与决策专家系统

分析了不同天气类型下影响参考作物需水量(ET0)的因素,建立了不同天气类型下ET0实时预报模型.在此基础上,利用农田水量平衡原理,结合近年来烤烟节水灌溉研究的最新成果,建立了烤烟实时灌溉预报决策模型.以国家农业信息化科学技术研究中心研制的PAID4.0作为农业专家系统开发平台,运用VB语言扩展平台功能,开发了烤烟实时灌溉预报与决策专家系统.该系统以立足田间、面向基层生产管理者为出发点,充分体现了实用性、准确性和可操作性,可以为贵州省水资源短缺和时空组合差的烟区的灌溉决策提供更加有力的科技支撑.

Real-time forecast and decision-making system for irrigation of flue-cured tobacco

By analyzing the factors influencing the reference evapotranspiration (ET_0) with different weather types, a real-time forecast model for ET_0 was established. On this basis, according to the principles of farmland water balance and up-to-date results on research of water saving irrigation of flue-cured tobacco from recent years, a real-time forecast and decision-making model for irrigation of flue-cured tobacco was built. A real-time forecast and decision-making system for irrigation of flue-cured tobacco was developed using the platform for agriculture intelligent-system development (PAID) 4.0 of the China Agriculture Information Technology Research Center, and functions of the platform were expanded with the Visual Basic language. The system bases itself upon the farmland and serves the production manager at the grassroots level. It is practical, accurate and convenient. The system can provide powerful scientific support for irrigation decision-making in tobacco regions with shortages and poor-quality spatial and temporal combinations of water resources in Guizhou Province.
