设施芹菜水肥耦合效应模型探析

Model analysis on interaction of water and fertilizer of celery in green-house

摘要: 研究建立了设施芹菜水肥耦合效应模型，并通过模型优化求出最佳芹菜水肥组合为N肥525.9～572.1kg/hm²、P肥(P₂O₅)320.8～354.4kg/hm²、K肥(K₂O)572.3～574.8kg/hm²和灌溉量636～677.3m³/hm²·次。

Abstract: The model for interaction of water and fertilizer of celery in green-house was established. Through deteriorating the model, the best component of water and fertilizer is N 525.9～572.1kg／hm²，P₂O₅320.8～354.4kg／hm²，K₂O 572.3～574.8kg／hm², and irrigation water 636～677.3m³／hm²·once.
