摘要： 文章将作物所需灌溉量(包括养分和水)与影响作物吸收肥水的3个主要环境因素 (温室内光照强度?温度?空气相对湿度)相结合,并针对不同控制方式,分别建立了基于 人工神经网络的控制模型和基于多元线性回归的控制模型,并研制了一套基于单片机控制的 设施农业营养液自动供给系统?其灌溉量控制模型的研究和该套控制系统的研制对我国设施 农业朝智能化?高效化方向发展起到了促进作用?

关键词: 控制模型, 灌溉, 营养液, 单片机

Abstract: Two control models are brought out in this paper, which are both the relation of the amount of irrigation crops need and the three main environment factors effecting the quantity of water and fertilizer crops absorb: illuminatio n, temperature and humidity. The control model makes a progress on agriculture. The authors develop a nutrient solution system based on micro-controller, which is small, low-cost, a high resist on interfere and easy to popularize. It is a n ew test on automatic technology for greenhouse farming.
