【Abstract】 The seasonal variation, the vertical distribution, and the survival of phytophora capsici Leonian in main vegetable soil in Shanxi were studied. The results showed that the closest relationship existed between the group quantitative change of phytophora capsici Leonian and temperature. The quantity of the bacterium was the largest during summer and autumn, and the suitable temperature for the bacterium to grow was 25～28℃. Most part of the bacteria distributed in the depth of 0～10 cm soil.更多还原
