【Abstract】 The effects of acetochlor on the population of soil microbe and the growth of bacteria,actinomyces and funguses in soil were studied. The effects of acetochlor on respiration of soil microbe were studied by closed or direct absorption method. The results showed that acetochlor inhibited the population of soil microbe and the growth of bacteria,actiinomyces and funguses in soil and the respiratiion of soil microbe at different degree.更多还原
