Abstract Taking ‘Jiushen F1’ leek as experimental material，this paper studied the effects of using slow-release fertilizer to replace common chemical fertilizer combined with bio-organic fertilizer application，and treating soil by lime nitrogen on the growth physiology and yield of Chinese chive．The results showed that comparing with the contrast by conventional treatment，the treatment of using 70.3 kg ·（667 m2）-1 slowrelease fertilizer to replace common chemical fertilizer，combined applying 200-400 kg·（667 m2）-1 bioorganic fertilizer and 50 kg ·（667 m2）-1 lime nitrogen soil treatment could promote leek plant height，stem diameter and leaf length，increas yield，improve quality and reduce the use level of chemical fertilizer．Among them，the yield had increased by 9.78%-14.84%，contents of soluble sugar and VC in leaves increased by 11.40%-13.97% and 27.27%-40.91%，respectively；activities of nitrate reductase，contents of chlorophyll and carotenoids were increased by 22.69%-23.26%，21.69%-34.94% and 13.33%-26.67%，respectively；nitrate content had decreased by 8.79%-10.93%．
