| 摘 要： | 在田间条件下用溴甲烷(68.1g/m2)、威百亩(7.5mL/m2)进行土壤熏蒸,调查两种药剂对土壤微生物及硝化作用的影响。结果表明:两种熏蒸剂对土壤放线菌无抑制作用,对细菌总量影响较小,但亚硝酸细菌受到强烈抑制,土壤的硝化作用受到明显影响;同时,土壤中真菌的数量及种类变化显著。熏蒸后9周,处理区土壤中的微生物基本恢复正常。

| Abstract: | Effect of methyl bromide(68.1g/m2)and methane sodium(7.5mL/m2)on soil microbe population and soil nitrification capacity was investigated in field.Results show no fumigant inhibition on actinomycete population,but some degree of fumigant inhibition on total bacteria population is noted.However,nitrite bacteria population and soil nitrification capacity are strongly inhibited.The number and kinds of soil fungi change significantly after fumigation.Soil microbes recover to normal levels 9 weeks after fumigation. |
