摘要：Effects of several different herbicides on soil microbiological activity in wheat crop were investigated.The effects depended on the types of herbicides and microorganisms,and the duration of herbicide activity.The most inhibitory effect was caused by the herbicide Orbit.Azotobacter was found to be the most susceptible to herbicides.The abundance of actinomycetes and fungi increased under the activity of investigated herbicides.Inhibitory effects of herbicides were at their highest points after 15 days and the lowest 120 days after treatment.
