摘  要：
为了明确1,3-二氯丙烯与氯化苦混用对土壤微生物数量的影响,采用室内培养的方法,研究4种剂量熏蒸处理后,供试土壤中微生物数量变化。结果表明:混剂熏蒸土壤后,低剂量(25.78 mg/kg)对放线菌表现为"抑制—恢复"趋势,中高剂量(128.91 mg/kg,257.81 mg/kg和1289.06 mg/kg)表现为"抑制—激活"趋势,在试验后期(第112天)激活率为125.36%;细菌与放线菌表现的趋势相似,但是细菌出现激活的时间(第49天)较放线菌(第14天)的晚,且中高剂量在试验后期(第112天)接近对照水平;而对镰刀菌、疫霉菌及可培养真菌均表现出明显的抑制作用,但低剂量下镰刀菌、疫霉菌在第49天和可培养真菌在第28天恢复至对照水平,高剂量处理(1289.06 mg/kg)对其则表现出"抑制—激活"的趋势,并且在试验末期(第112天)激活趋势依然明显,激活率分别为99.19%、51.54%和225.64%。

摘  要：
In order to define the effects of the 1,3-dichloro acrylic blended with chloropicrin on soil microbial quantity, the microbial population changing in the soil was studied through laboratory experiment. The results indicated that low dose of actinomycetes(25.78 mg/kg) showed "inhibition-recovery", and the medium and high dose(128.91, 257.81, 1289.06 mg/kg) were in the form of "inhibition- stimulation", and the rate of activation was 125.36% in the late test(112th day). The trend of bacteria was similar to actinomycetes, but the time of stimulation for bacteria(49th day) was later than that of actinomycetes(14th day), at the same time the high dose was close to the control level in the late test(112th day). There were significant inhibitory effects on Phytophthora spp, Fusarium spp and the culturable fungi after the soil fumigation. But for low dose Phytophthora spp and Fusarium spp on the 49 th day and the culturable fungi on the 28 th day recovered to asimilar level of the controls. While those treated with high dose(1289.06 mg/kg) showed "inhibition-stimulation" and were still in the stimulation in the late test(112th day) with the rate of stimulation being99.19%, 51.54% and 225.64%, respectively.
