Abstract
Experiment studies the influence of the Bo sprinkling, ground insect killer, hypertonic imidaclo-prid, trichloro-4 pesticides on soil dehydrogenase activity and respiration. The results showed that; soil dehy-drogenase activity at low , reduced with the addition increase of hypertonic imidacloprid, triclosan, expressed as inhibition, when the concentration exceeds a certain threshold ,stabilized. The Bo sprinkling, insect killer to increase with the amount of pesticides, inhibition of dehydrogenase activity was first re-activated; adding an equal amount (0. 01ml) of pesticides in soil samples increased with incubation time was linear growth inhibition; Different pesticides on soil respiration showed an activation.关键词
