The study was conducted with brown soil(0-20 cm and 20-40 cm) in Shenyang agricultural university experimental station in order to research effecting mechanism of turnover
no-tillage
totary tillage on growth of maize's root.With pot experiment
it researched the impacts of different soil bulk density and sample from different soil layers on enzyme activities(polyphenol oxidase
catalase
acid phosphatase
urease
invertase).The results showed that the influence of different soil layers and different bulk density...
