文摘The relevant factors for physiological chlorosis of Cinnamomum camphora L. in Pingdingshan were studied combining with references and production sur- vey. The resuhs showed that the disease was the integrated results of soil environment, planting situation, microenvironment construction and maintenance manage- ment. Therefore, the countermeasures of ＂prevention first, restore tree vigor; integrated control, enhance tree vigor＂ were proposed. Chlorosis of C. camphora had been basically controlled after four years, and the control effect was obvious.
