| 中文摘要: |
| 结合田间取样调查及室内实验培养,在施药后20、40、60、80 d分别采集0~10 和10~15 cm的土样，采用微生物平板培养法和稀释平板计数法测定土样中的微生物，初步探讨了2种除草剂对马铃薯土壤的微生物生态多样性变化的影响。结果表明，施田补和氟乐灵这2种除草剂对马铃薯地0~10、10~15 cm 土壤的细菌和真菌数量影响不大；虽对于不同深度的土壤细菌和放线菌有一定的促进和抑制增殖的作用，在75 d内均可恢复至对照水平。 |
| 英文摘要: |
| Combine sampling surveys in field and laboratory culture experiments, the influence of Prowl and Trifluralin on potato soil microbial diversity was investigated. After applying herbicides, the soil samples of the depth of 0~10 cm and 10~15 cm are collected and processed on day 20 th, day 40 th, day 60 th and day 80 th respectively. Determine the population of microorganisms in soil samples by the way of microbial plate culture method and the dilution plate counting method. The effect on the change of ecological diversity Prowl and Trifluralin on potato soil microbial diversity was preliminary discussed. The study found that two herbicides have little influence on the number of bacteria and fungi to the potato soil of the depth 0~10 cm and 10~15 cm. Although there is certain promotion and inhibition of proliferation to the bacteria and actinomycetes of the soils, within the 75 d both of them can returned to the level of control. |
