摘要 以韭神F1 韭菜为试验材料，研究用缓释肥替代普通化肥并配施生物有机肥、石灰氮土壤处理对韭菜生长生理及产量的影响。结果表明：用70.3 kg ·（667 m2）-1缓释肥替代普通化肥，配施200～400 kg ·（667 m2）-1生物有机肥，50 kg ·（667 m2）-1石灰氮土壤处理可较常规施肥的对照促进韭菜株高、茎粗、叶长，提高产量，改善品质，并减少化肥用量。其中，产量增加9.78%～14.84%，叶片可溶性糖和VC 含量分别提高11.40%～13.97% 和27.27%～40.91%，硝酸还原酶活性、叶绿素和类胡萝卜素含量分别提高22.69%～23.26%、21.69%～34.94% 和13.33%～26.67%；硝酸盐含量降低8.79%～10.93%。
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%．
