大蒜根际土壤微生物数量及酶活性动态研究
Dynamic Study of Microbial Population and Enzyme Activity in Rhizosphere Soil of Allium sativum L.
摘要
Abstract
[ Objective] The aim was to investigate the changes in rhizosphere microbial population and soil enzyme activities of the two cultivars of Alliurn sativurn L. at different stages. [ Method ] By using white garlic and purple garlic as the experimental materials, the microbial population, and the urease, acid phosphatase, catalase activities in rhizosphere soil at different growth stages were measured. [ Result ] The root exudates of the two garlic cultivars could promote the growth of bacteria, fungi and actinomycetes, and thus indirectly increase the urease,acid phosphatase and catalase activities in rhizosphere soil, thereby improving the turnover and circulation of the soil nutrition elements such as nitrogen and phosphorus and providing a better micro-ecological environment for the later crop. [ Conclusion] The study had provided theoretical basis for the ecological research on garlic used as a preceding crop.关键词
