Abstract: The effect of combined application of biogas residue and biogas slurry on the growth and fruit of greenhouse strawberry‘Zhangji’was studied by a field experiment with farmyard manure and combined application of chemical fertilizer used as CK under the same application amount of nitrogen, phosphorus and potassium nutrient. The results showed that: compared with CK, combined application of biogas residue and biogas slurry could promote strawberry nutrition and reproductive growth, the plant height increased by 2.1 cm, leaf area increased by 17.41%, different growth periods were 1-3 days ahead of time; fruit weight and yield of strawberry were also improved, the single fruit weight of first order fruit, mean single fruit weight and yield increased by 11.69% , 14.47% and 12.3% . In addition, fruit soluble solids and VC content significantly increased, and the titratable acid content reduced and strawberry quality was improved.
