Abstract: Year- cycle soil factors of normal and chlorosis camphor were surveyed on both sides of the 6th road ofHangzhou economic and technological development zone located in the north shore of the Qiantang River.The results ind-icated that soil pH,HCO3-and available phosphorus of chlorosis trees were higher than normal trees, while its availableiron and organic matter were lower. Among four sampling t imes, the order of chlorosis from light to heavy was August,June,March and October, the chlorosis from south side of the road was lighter than north side, topsoil quality is poorer.And on this basis a new fertilizing method of camphor was recommended to provide for treating and preventing of chlorosiscamphor.
