- 摘要:
- 从古松根区的纵向和横向研究了沈阳福陵不同深度古松土壤养分状况。结果表明：在距树干4 m处可能是古松根系吸收养分较强的地方；钾素营养并不是引起古树衰弱的主要因素，而土壤有效氮和有效磷，特别是距树干4 m处土壤的有效氮和有效磷供给量可能与古树衰弱枯死有一定的关系。
- Abstract:
- The aged-pine’s soil nutrient status property of root district from lateral and longitudinal direction in Shenyang east imperial tomb was studied.The results showed that the most nutrient was absorbed at 4 m distance from aged-pine trunk；potassium was not the main factor caused aged-pine’s weak,but soil available nitrogen and available phosphorus，particularly from the trunk 4 m soil available nitrogen and available phosphorus supply would be associated with weak and wither of aged-pine.
