Abstract: 【Objective】To explore the effects of sheep dung anaerobic and aerobic compost extracts on the growth,yield,quality of pakchoi and soil salt content.【Methods】With pakchoi as test samples,taking a pot experiment in greenhouse,five treatments including no organic fertilizer and chemical fertilizer（CK）,single compound fertilizer（T1）,sheep dung anaerobic compost extract（T2）,sheep dung aerobic compost extract（T3）,rotten sheep dung compost（T4）,comparative analysis of pakchoi growth,yield,quality and soil salt content were done.【Results】The soil total potassium content and available nitrogen content of T1 treatment were 21.30 g/kg and 232.00 mg/kg,which were significantly different from those of other treatment groups（P<0.05）. The plant height,nitrate content,protein content and VC content of T2 treatment were 22.25 cm,4 022.00 mg/kg,3.06 g/100 g and 45.80 mg/100 g,which were significantly different from those of other treatment groups（P<0.05）. The weight per plant,yield of pakchoi and soil total nitrogen content in T3 treatment were 23.65 g/plant,31 545.00 kg/hm² and 2.92 g/kg,which were significantly different from those of other treatment groups（P<0.05）.【Conclusion】After applying sheep dung anaerobic compost extract and aerobic compost extract,pakchoi grew vigorously,yield was higher and quality was improved,which also played a positive role in the improvement of soil secondary salinization in greenhouse.
