北京天坛公园土壤研究——Ⅱ.土壤养分状况及其变化规律

A STUDY ON THE SOIL OF TIAN TAN PARK IN BEIJING——Ⅱ. The condition and the changing regularity of nutrient in the soil

本文研究了天坛公园土壤的有机质、全氮、速效氮、全磷、速效磷、速效钾、CaCO_3含量、土壤pH及全盐含量等的分布及其转化规律.探索了园林内土壤与一般同土类同质地的农耕地土壤之间的相似性和特殊性.证实了某些土壤不良的物理性状对土壤氮素转化有很大影响,为园林内土壤的改良及培肥提供了理论依据.

This essay contains the study on the distribution and the changing regularity of total N, quick-acting N, total P, quick-acting P, total K, quick-acting K and CaCO_3, the pH of soil and all salt in the soil in Tiantan park. The same and the difference between the park soil and the same kind soil in cultural land are researched. It makes it clear that there's a large affection of some bad physical quality of soil on the change of N, It gives a theory basis in the improvement and the fattening on park soil.
