Abstract： For three consecutive years， the mixed application of chemical slow-release fertilizer and vermicompost in cherry orchard was tested to study its effects on soil physicochemical properties and soil enzyme activities. The results showed that compared with the application of slow-release fertilizer alone， the mixed application of chemical slow-release fertilizer and earthworm manure could significantly improve the activities of soil urease， catalase， polyphenol oxidase and sucrase， increase the microbial content， effectively improve the contents of soil organic matter， available nitrogen， available phosphorus， available potassium and soil p H ，and the electrical conductivity EC of soil also increased to varying degrees.

Key words：sweet cherry; slow-release fertilizer; earthworm manure; soil physicochemical properties; enzyme activity

为了增加经济效益，甜樱桃生产中存在加大化学肥料施用以增加产量的情况，但是长期过度施用化肥会加剧土壤环境的恶化，土壤有机质含量严重不足，土壤板结，土壤酸化，并出现地下水和硝态氮含量超标等问题，成为制约甜樱桃产业可持续发展的因素之一。（剩余3479字）
