The invention discloses bacillus velezensis and an application thereof to relieving continuous cropping obstacles of apples. The bacillus velezensis is preserved in China General Microbiological Culture Collection Center on June 10, 2020, and the biological preservation number of the bacillus velezensis is CGMCC NO. 20057. The bacillus velezensis XC1 provided by the invention is a novel biocontrolbacterium having great development potential and has a relatively strong inhibition effect on f. oxysporum, f. moniliforme, f. proliferatum and f. solani, and the inhibition rate of the bacillus velezensis XC1 on the f. oxysporum is the highest and reaches 79.83%. The strain can achieve high yield of antagonistic enzymes such as protease and cellulase; the content of phenolic acid substances suchas phlorizin, phloretin, ferulic acid and cinnamic acid in the soil is reduced; apple tree plant growth is promoted; the method has an excellent effect in relieving continuous cropping obstacles of apple trees, and provides a
