摘　　要：在山东省即墨市日光温室内进行番茄、芹菜的氨基酸液肥肥效试验,以N12-P12-K15复合化肥为对照。通过对2种蔬菜植株的农艺性状、叶片叶绿素含量、叶片净光合速率、产品器官和土壤的硝酸盐含量以及产量的测试调查,结果表明,以氨基酸液肥为追肥肥料可比复合化肥在提高植株生长势、增加产量、改善品质、降低土壤及蔬菜体内硝酸盐积累方面有更好的效果。Experiment of amino acid liquid fertilizer efficiency on tomato and celery was carried out in Jimo of Shandong Province, taking N12-P12-K15 compound fertilizer as control in greenhouse. The agronomic characters, chlorophyll content of leaves, net photosynthesis rate of leaves, nitrate content of leaves and soil, and yield of tomato and celery were tested. The result showed that the plant growth vigor, yield, and quality could be effectively promoted by the treatment of amino acid liquid fertilizer, also the nitrate content of vegetables and soil were reduced.
