摘要
采用土壤养分状况系统研究法,对左权、和顺两地的石灰性褐土进行养分状况系统研究,结果表明,左权土壤养分限制因子主要是P、N、Zn、Cu,和顺土壤养分限制因子主要是P、N、K,与田间校验结果总趋势相一致。
The nutrient status in the calcareous cinnamon soil,which was collected from Zuoquan and Heshun,was studied with a systematic approach on soil nutrient status . The result displays that the main soil nutrients limiting factors of Zuoquan Cinnamon soil are P N Zn Cu,P N K of Heshun ,which is the same as the result of experiment in the field.
