摘要: 对位于钱塘江北岸杭州市经济技术开发区六号路两旁黄化和正常樟树土壤因子年周期变化规律作了研究,结果发现黄化樟树立地土壤pH、HCO3-和有效磷均比正常树高,而有效铁和有机质比正常树低,四个取样时期樟树黄化从轻到重顺序依次为8月、6月、3月和10月,路南比路北黄化程度要轻,表层土质差。并在此基础上对樟树施肥提出建议,为治理和预防樟树黄化提供新的依据。

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.
