调节茶园土壤pH对土壤养分、酶活性及微生物数量的影响
Effects of Adjusting pH of Tea Plantation Soil on Its Soil Nutrients, Enzyme Activity and Microorganisms
摘要
Abstract
[Objective] The research aimed to investigate the effects of acidification and alkalization on soil nutrients, soil enzyme activity and microbial quantity in tea plantation soil so as to further explore the mutual relationship between them and the change of pH. [ Method] The study was conducted by regulating the soil pH of the tea plantation soil with lime on the soil nutrients, enzyme activity and microorganism. [ Result ] Acid soil, with its pH improved by 1 - 2 units would cause the soil available phosphorus and soil exchangeable acid to reduce. And the quantity of bacteria and aetinomyces in the soil would increase by about 10 times. With pH increasing, the fungi decreased. The activity of catalase, polyphenol oxidase, the urease in the soil increased with pH regulation. [ Conclusion ] As the days went on, soil pH decreased. The available phosphorus, exchangeable acid, the number of fungi and invertase activity in the soil were negatively correlated with pH. The quantity of bacteria and actinomyces in the soil and the activity of catalase, polyphenol oxidase, urease were positively correlated with pH.关键词
