Abstract: Low extension and conversion rates of the scientific and technical results from forestry and agricultural research programs are the critical factors confining the progress of science and technology in forestry and agriculture. According to the present situation of land-use in the project implementation area, the participatory approach for forestry technology extension was introduced by the technology-transfer project of directional cultivation for high-yielding plantation of large clustered shoot and timber production bamboos. It was proved that the participatory approach could not only greatly motivate the production enthusiasm of local farmers, but could also promote the interest and capacity of self-development of rural households and harmonize well the triple relations among the local government, households, and the project conductors. As the result, the technique extension was implemented successfully.
