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
為了增加經(jīng)濟(jì)效益,甜櫻桃生產(chǎn)中存在加大化學(xué)肥料施用以增加產(chǎn)量的情況,但是長(zhǎng)期過(guò)度施用化肥會(huì)加劇土壤環(huán)境的惡化,土壤有機(jī)質(zhì)含量嚴(yán)重不足,土壤板結(jié),土壤酸化,并出現(xiàn)地下水和硝態(tài)氮含量超標(biāo)等問(wèn)題,成為制約甜櫻桃產(chǎn)業(yè)可持續(xù)發(fā)展的因素之一。(剩余3479字)
