| 摘 要： | 为了探讨鞍山市千山风号区近年来出现的松树小面积死亡的原因，在风景区代表性地区选择了7个样点14个土壤剖面，测定其pH值、土壤含水率、全氮、全磷、碱解氮、速效磷、钾等9个土壤理化指标．结果表明：活树的土壤含水率高于死树；pH值过高导致松树死亡；速效磷过高导致松树死亡；养分总量是松树生长的总体控制因素．

| Abstract: | Study was carry out to look for the reasons for death of pine trees in Qianshan Mountain scenic area.The soil characteristics were studied by determining the pH,soil water content,total N,total P,available N,available P and K of 14 soil profiles at 7 sampling sites.The results showed that the soil water content of sites with more tree death was lower,too high pH and too high content of available P resulted in the death of tree.The contents of nutrients in soil was the general controlling factor for the grow... |
