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/hm^2、P肥(P205)320.8~354.4kg/hm^2、K肥(K2O)572.3--574.8kg/hm^2和灌溉量636~677.3m^3/hm^2·次。
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. 1 kg/hm^2, P205320.8- 354.4kg/hm^2, K2O 572.3 - 574.8kg/hm^2, and irrigation water 636- 677.3m^3/hm^2 ·once.
