Abstract: By means of estabilishing standard land, we revealed the interaction of factors affecting the occurrence of the root rot on Chinese prickly ash through the path analysis. The population of Fusarium solani in soil was a primary factor to the disease. The models of forecasting the output of the disease plant were estabilished on the basis of the linear relation between a single tree's output (dry weight) and the disease index, and the population of the pathogen in soil.
