| Abstract: | The results of the study showed that:The contents of the soil bacteria in each soil layer were increased significantly by covering during the whole growing period of the fruit trees Among 0～20 soil layer the annual average contents of the bacteria were increased 82 12%, increased 233 69% among 20～40 soil layer, increased 144 80% among 40～60 soil layer The variations of the bacteria contents in each soil layer were unimodal distribution The peaks appeared in August |
