[目的]研究大蒜不同时期根际的微生物数量及土壤酶活性的变.[方法]以白皮蒜和紫皮蒜为试验材料,分别测定不同时期根际微生物数量,及土壤脲酶酸性磷酸活性。[结果]各时期2个大蒜品种均促进了根际土壤中细菌、放线菌和真菌的生长,间接提高了根际土壤中脲酶、磷酸酶和过氧化氢酶的活性,从而提高了大蒜根际土壤中氮、磷等营养元素的周转与循环,为下茬作物生长提供了良好的微生态环境。[结论]该研究为大蒜作为一种良好的前茬作物的生态学研究提供理论依据。
[Objective] The research aimed to study the change of microbial quantity and enzyme activity in the rhizosphere of garlic at different stages. [Method] With rhizosphere microbes and soil urease acidic phosphatase activities of white garlic and purple garlic as test materials, [Result] The two garlic cultivars promoted the growth of bacteria, actinomycetes and fungi in the rhizosphere soils and increased the activities of urease, phosphatase and catalase indirectly in the rhizosphere so as to increase garlic root The turnover and circulation of nitrogen, phosphorus and other nutrients in the inter-soil soil provide a good micro-ecological environment for the growth of the next crop. [Conclusion] This study provided the theoretical basis for the ecological research of garlic as a good former crop.
