保定市植物园土壤特性研究

利用常规分析方法对保定植物园土壤进行了主要特性指标的分析研究，结果表明：植物园土壤pH值偏高，呈微碱性-碱性反应，其中75％达到8．01以上；CaCO3含量较高，石灰反应强烈；土壤质地以壤质为主，但偏粘重；土壤有机质、碱解氮和速效磷含量偏低，速效钾含量中等，土壤养分总体水平不高。据此提出了土壤培肥、管理、改良的建议，为园林植物更好地生长，以及充分而长久的发挥植物园的特有功能提供了理论依据和具体实施的措施。

The study on the specific property of soil in the botanical garden of Baoding

According to convention analysis and study on the soil of the botanical garden of Baoding, It can be known that: pH values there are a little higher, so the soil is alkaline soil. 75% of them are above 8.0; the content of CaCO_3 is high; the chemical reaction of lime is severe very much; the soil texture is mainly the loam, but it's a little thicker; the content of the organic matter, ammonium nitrogen,the available P are a little lower, but the content of the avaivlable K is much higher; the total degree of the soil nutrient is not high. In terms of the condition, the paper offered several suggestions about the soil's fertilizations, managements and improvements, in order to provide the theoretic warranty and idiographic measures for the better growing of the garden plants and the full and long-going exertion of the own functions of the botanical gardens.
