肥水管理作为现代温室作物无土栽培成败的关键技术,长期以来作为研究热点而备受关注。本文从温室作物生产过程中肥水耦合的特点(即营养液的方式)出发,首先回顾和评价了营养液的灌溉量和灌溉频率的4种确定方法(计算法、目标产量配方法、基于模型的和基于专家决策支持系统的方法),然后在此基础上讨论了营养液的管理(包括营养液浓度、p H值、溶解氧和温度的管理),最后初步提出了该领域存在的问题并对未来的研究热点进行了展望。
Fertilizer and water management, as the key technology of soilless cultivation of modern greenhouse crops, has long been a hot spot for research. Based on the characteristics of fertilizer and water coupling (ie, the way of nutrient solution) during crop production in greenhouse, this paper firstly reviews and evaluates four methods of determination of nutrient solution irrigation and irrigation frequency (calculation method, target yield method, model-based And expert-based decision support system). Based on this, the management of nutrient solution (including nutrient solution concentration, p H value, dissolved oxygen and temperature management) was discussed. Finally, the problems in this field were initially proposed The future research hot spots are prospected.
