摘要 基于PC机及C8051F80X单片机的智能化滴灌及施肥管理系统能够监控不同土壤的湿度,并根据农作物对土壤的不同湿度要求,从而实现适量、适时灌溉的目的。在进行灌溉的同时,把测土配方后的肥料通过输水管道输送到植物根部,科学合理的进行水肥供给。单片机和PC机是智能化滴灌及控制施肥的核心部分,对土壤灌水量与湿度的关系、智能滴灌技术、控制系统的硬软件等部分进行了探讨与研究,同时根据不同的作物对各类肥料有不同的需求率和利用率,对不同的植物采用不同的施肥方式,提高肥料利用率。把灌溉和施肥结合起来,可以完成对作物生长期各个阶段的肥料及水分需求进行统计,形成农业专家数据库,真正作到科技兴农。

Abstract PC and C8051F80X single chip computer intelligent drip irrigation and fertilization management system can monitor based on different soil humidity, and according to the requirements of different crops on the soil humidity, so as to achieve the purpose of appropriate, timely irrigation. In irrigated at the same time, the soil testing and fertilizer after delivery to the roots of the plant through the water pipe, the scientific and reasonable water and fertilizer supply. PC and MCU is the core part of intelligent drip irrigation and control fertilization, the relationship of soil irrigation quantity and humidity, intelligent drip irrigation technology, control system hardware were discussed and studied, at the same time, according to the different crops on various types of fertilizers have different needs and utilization rate, for different plants by different fertilization methods, the utilization rate of the fertilizer was improved. The irrigation and fertilization combination can finish statistics on fertilizer and water demand of crops in each growth period, and form agricultural expert database.
Key words C8051F80X; Fuzzy control

我国人均占有水资源非常贫乏。当前,全国总缺水量超过400亿m3,其中农业是用水大户,约占70%,而灌溉用水是农业用水的90%。采用传统的灌溉模式,全国平均用水量超过实际需要的1~2倍,有些地方是2倍以上。当前,我国灌溉水资源的浪费情况相当严重,节水的潜力十分巨大。
当前制约我国农业发展的因素中,除了水资源的贫乏,还有肥料利用率偏低的问题。我国耕地面积占世界的7%,施肥量却占到了世界施肥总量的30%。不能科学合理地施用化肥也使得农业种植成本增高,造成资源浪费和经济损失,更重要的是对生态环境造成污染,所以必须提高肥料利用率。……
