光合叶面积对人参全氮、全磷和全钾含量变化的研究

摘要

In order to deeply understanding the absorption and utilization of hinges light area on the ginseng total nitrogen, total phosphorus and total potassium, Conventional analysis methods were adopted on different growth stage 3,4 years stems and the ginseng to total nitrogen, total phosphorus, total potassium content changes in this paper, no matter total nitrogen, total phosphorus, or total potassium, from exhibition leaf stage to the flowering period they are showing a downward trend. Total nitrogen content of 3 years stems ginseng is and higher than four years stems one, total nitrogen content reached minimum during green fruiting period, content of total nitrogen reached highest in red fruits period;the flowering terms contains minimum total phosphorus;Total potassium content reached highest;For different reproduction stages of the stem and ginseng, content and form of nutrient absorption and utilization showed regtdar changes through main nutrient determination analysis.%为了深入了解不同生育期多茎参人参的全氮、全磷、全钾的吸收利用情况．运用常规的分析方法对不同生育期3、4年多茎参人参的全氮、全磷、全钾的含量变化研究中发现，不管是全氮，全磷，还是全钾．展叶期到花期这个时期他们都是呈现下降的趋势。全氮含量3年多茎参高于4年多茎参，绿果期全氮含量最低，红果期全氮含量达最高值；全磷含量在花期最低；枯萎期全钾含量最高。通过对各主要养分的测定分析，发现在不同的生育期多茎参人参中各养分形态及含量的吸收和利用呈现规律性变化。
