Effect of Acetochlor on Soil Microorganism in Ramie Field

An experiment was conducted to determine the effect of acetochlor application on soil microorganisms in the ecosystem of ramie field.Three acetochlor solutions with different concentration were respectively sprayed in different areas of ramie field to observe its effect on the amount of bacteria,fungi,and actinomycetes.The results showed that the amount of bacteria,fungi,and actinomycetes were inhibited after applying acetochlor,then gradually recovered.The amount of bacteria,fungi,and actinomycetes significantly decreased at the 7th day and the trend was more notable with the increase of acetochlor concentration,then these three microorganisms were gradually restored.
