摘    要:为了探明设施西芹适宜腐植酸施用量,以美国西芹为试验材料,采用随机区组设计,研究了不同腐植酸施用量对设施西芹地上部产量及养分含量、养分吸收量、养分吸收利用率的影响。结果表明:西芹地上部鲜重和干重随腐植酸施用量增加呈先增加后减少趋势,各施肥处理与对照相比鲜重增产率在5.33%~7.78%之间,干重增产率在5.32%~7.89%之间,以H138处理效果最明显,其次是H184处理;增施腐植酸可显著提高西芹氮、磷、钾含量和氮、磷、钾吸收量及氮、磷、钾吸收利用率,以H138处理效果最明显。综合考虑,当地设施西芹适宜腐植酸施用量为138kg/hm2。

Abstract:To identify the proper humic acid fertilizer dosage of facility celery,the authors used random block design to study the effect of different humic acid fertilizer application amount on celery's yield,nutrient content,nutrient absorption amount and nutrient absorption and utilization efficiency.The results showed that the celery fresh weight and dry weight of overground part increased with the increase of the application amount,and then decreased;compared with CK,the increasing rate of fresh weight was 5.33% to 7.78%,and that of dry weight was 5.32% to 7.89%;H138 had the highest increment,then was H184.The application of humic acid fertilizer could significantly increase the content of N,P and K and the absorption amount of N,P and K and the absorption and utilization efficiency of N,P and K in celery,and H138 had the most obvious effect.Therefore,the optimum dosage of humic acid fertilizer should be 138 kg/hm2 for facility celery.
Keywords:Celery   Fresh Weight   Dry Weight   Nutrient Content   Nutrient Absorption Amount   Nutrient Absorption and Utilization Efficiency
