Effects of vegetation, soil and topography on growth of Pleioblastus chino Makino

The factors of spreading Pleioblastus chino Makino into secondary forests floor was studied. The analysis by quantification theory first family shows that the growth of P. chino was activated in soil pH more than 4.9 area, but the growth of P. chino was suppressed in soil pH under 4.3 area. The growth of P. chino was also activated in gentle inclined area of the bottom of slope and the border on path and coppicing area. The vigor of P. chino was less under the canopy of Pinus densiflora Sieb.. It is important that P. chino should be controlled in priority at areas where the growth of P. chino is activated.
