Abstract: 【Objective】 To explore the effects of sheep dung anaerobic and aerobic composting extracts on tomato yield,quality and soil nutrient content in greenhouse. 【Methods】 To compare and analyze tomato plant traits,fruit traits,yield,quality and soil nutrient content in greenhouse,5 treatments were conducted,no fertilizer（CK）,organic fertilizer（F1）,sheep dung anaerobic composting extract（F2）,sheep dung aerobic composting extract（F3）,and single fertilizer（F4）. 【Results】 Plant height（173.60 cm）,stem diameter（16.48 cm）,fruit transverse diameter（78.02 mm）,fruit longitudinal diameter（57.68 mm）,average single fruit weight（0.20 kg）,yield（138 000 kg/hm²）,fruit soluble total sugar content（6.05%）,center sugar content（5.50%）in F2 treatment were significantly different from other treatments（P<0.05）,and the soil organic matter content（71.00 g/kg）,total nitrogen content（3.55 g/kg）,hydrolyzable nitrogen content（262.00 mg/kg）,available phosphorus content（277.60 mg/kg）,available potassium content（535.00 mg/kg）,the total amount of water-soluble salt（0.70 g/kg）were also significantly different from other treatments（P<0.05）. Leaf width（15.20 cm×8.50 cm）,plant width（50.00 cm×55.00 cm）,relative chlorophyll content（73.45%）and fruit VC content（27.60 mg per 100 g fresh fruit）in F3 treatment were significantly different from other treatments（P<0.05）,and the total potassium content of the soil（26.00 g/kg）and pH value（7.91）were also significantly different from other treatments（P<0.05）. Compared with other treatments,the total acid content（4.80 g/kg）and soluble solid content（7.50%）of tomato in F1 treatment were significantly different（P<0.05）,and the soil total phosphorus content（1.66 g/kg）was also significantly different from other treatments（P<0.05）. 【Conclusion】 After applying sheep dung anaerobic composting extract and aerobic composting extract,greenhouse tomatoes grew better,yield increased,and quality improved. The composts also had a positive effect on the improvement of soil nutrients in the greenhouse.
