摘要: 通过对相同林型下榛属群丛和非榛属灌木丛下根区土壤的对比研究,发现榛属群丛下根区土壤较非榛属灌木下土壤pH值增高,有机质含量显著增加,全N和碱解氮、全磷量显著提高,有效磷降低土壤团粒结构增加,水稳性提高。表明榛属灌丛有明显地改良土壤理化性质的作用。

Abstract: By study of the root zone soil under the Corylus and non Corylus clusters we know that the pH value is higher, the contents of soil organic matter, total nitrogen, alkali-discomposed nitrogen and total phosphorus are higher, the content of the available phosphoru is lower and the soil granular structure and the durability of water are higher under the Corylus cluster.The results show that the Corylus cluster have an important function in ameliorating the physical and chemical properties of soil.

Key words: Corylus, Physical and chemical properties of soil
