摘要
精准水肥灌溉是设施农业的重要组成部分,由于不同品种的作物对水肥需求不同,以及同种作物处于不同生长期时的需求也不同,精准水肥灌溉结合作物的自身生长状况及生长环境参数,通过模型耦合作物与环境信息,智能决策作物的需求状况。文章介绍了精准水肥灌溉技术的相关概念,分析了实行精准灌溉的必要性,并从灌溉系统、营养液调配策略、基于作物需水量计算和基于作物表型分析两种方式的灌溉策略等方面分析了研究现状,指出了现阶段研究的不足。建立了水肥灌溉量与作物动态表型和环境参数的关系预测模型,展望了建立精准灌溉决策系统的两阶段。
Precision irrigation of water and fertilizer refers to the realization of integrated precision irrigation of water and fertilizer by coupling crop and environmental information and intelligent decision⁃making of crop water and fertilizer demand according to the water and fertilizer demand,fertilizer demand law and nutrient content status,crop growth environment parameters and crop growth information in different growing periods of crops.This paper introduces the related concepts of precision water and fertilizer irrigation technology,analyzes the necessity of precision irrigation,and analyzes the current research situation from the aspects of irrigation system,nutrient solution allocation strategy,crop water demand calculation and crop phenotype analysis.In order to establish the prediction model of the relationship between irrigation amount of water and fertilizer and crop dynamic phenotype and environmental parameters,the two-stage decision making system of precision irrigation was prospected.
