本文通过对沈阳东陵的部分古油松周围土壤条件的调查,并且对土壤物理性质、土壤化学性质以及土壤养分的研究分析。结果表明:土壤的表层水分含量高达25.1%,超出其适宜范围,易造成古油松烂根;土壤渗水性较差,不利于排水。土壤总孔隙度适中,但毛管孔隙度过高,非毛管孔隙度过低,多为2.8%~7.8%,小于最低限。土壤酸性过强,不利于古油松生长。土壤缺乏有机质和全N,而有效Zn、有效Cu、有效Fe含量均偏高,直接影响古油松的生长。建议改善土壤条件,从而改变东陵古油松生长衰弱的现状。
Based on the investigation of the soil conditions around the part of Pinus taiwanensis in Shenyang’s eastern tomb, this paper studied and analyzed the soil physical properties, soil chemical properties and soil nutrients. The results showed that the surface water content of soil was as high as 25.1%, which was beyond its suitable range, which could easily cause the rotten root of ancient Chinese pine. The soil water permeability was poor, which was not conducive to drainage. Soil total porosity is moderate, but capillary porosity is too high, non-capillary porosity is too low, mostly 2.8% ~ 7.8%, less than the minimum. Soil acidity is too strong, is not conducive to the growth of ancient Chinese pine. Soil lack of organic matter and total N, and effective Zn, available Cu, available Fe content are high, a direct impact on the growth of the ancient Chinese pine. Suggest to improve the soil conditions, thereby changing the status quo of the ancient Chinese pine Pinang growth and weakness.
