摘要
为了研究日用洗涤剂对作物耕作土壤可培养微生物活菌浓度的影响,选取6种日常使用的洗涤剂,包括香皂、洗衣粉、洗发露、洗洁精、沐浴露、洁厕精,配制洗涤剂稀释溶液,以去离子水为对照,在室温和28℃下浸泡花生地黄棕壤和稻田淤泥,选取5种培养基YMA、YPD、LB、GAU(高氏1号培养基)、PDA,通过稀释涂平板数菌落的方法,测定土壤活菌数浓度。结果表明,相比对照,洁厕精影响不显著,其余5种洗涤剂显著提高两种土壤样品可培养微生物浓度0~3个数量级,香皂、洗衣粉、洗发露、洗洁精、沐浴露可显著提高土壤可培养微生物活菌浓度。
In order to study the effects of daily necessary detergents on the concentration of crop cultivated soil microorganisms,six daily necessary detergents of dilutions such as perfumed soap,washing powder,shampoo,dish washing liquid,bath lotion,and lava⁃tory cleanser were prepared to immerse yellow brown soil sample from the peanut cultivation field or muddy soil from the paddy field at room temperature or 28℃for 14 days or 36 days,with deionized water serve as a control,in which the concentration of alive cultivat⁃ed microorganisms was evaluated by plate count method using 5 culture media such as YMA,YPD,LB,GAU,and PDA.The results showed that compared to the control,the lavatory cleaner dilution had little effect on the concentration of the microorganisms,howev⁃er,the other five dilutions had markedly improved to about 0~3 order of magnitudes.Perfumed soap,washing powder,shampoo,dish washing liquid,and bath lotion increased the concentration of crop cultivated soil microorganisms.
