Abstract: Experiments were conducted on combustion efficiency of the combustion block of Solidago canadensis L.with different pressures and different temperatures.The results indicated that it had difference among different pressures.It had a great difference among different temperatures.But it had no difference between two factors.Multiple comparisons showed that it had best compaction effect with 60℃ and different pressure.The outhor holds that the combustion block of Solidago canadensis L.takes account to the dual goal of integrated control and gets economic,social and ecological benefits.

Key words: Solidago canadensis L., combustion block, combustion efficiency
