Abstract:

In order to understand the differences of rhizosphere soil nutrients among different tree species in mountain areas of northern Hebei,the chemical properties of rhizosphere soil of six tree species(Larix principisrupprechtii,Betula platyphylla,Juglans mandshurica,Ulmus pumila,Sorbus pohuashanensis and Pinus sylvestris)in the region were analyzed.The results showed that:1)among the total nutrients in rhizosphere soil of the six tree species,the content of total organic carbon in soil ranged from 33.90 to 107.65 mg/g,the content of total nitrogen in soil ranged from 2.40 to 8.65 mg/g,and the content of total phosphorus in soil ranged from 627.35 to 829.60mg/kg.Among them,Juglans mandshurica had the highest content of total phosphorus,and Betula platyphylla had the highest content of total nitrogen and total carbon.2)The highest content of ammonia nitrogen in soil was Pinus sylvestris,which was significantly higher than that of other tree species;Juglans mandshurica had the highest content of available phosphorus in soil;Ulmus pumila had the highest content of nitrate nitrogen,available nitrogen,and available potassium in soil.3)The range of C/N,C/P and N/P in rhizosphere soil were 11.64~12.62,69.34~128.10 and 4.89~10.29,respectively.Pinus sylvestris had the highest C/N ratio,and Betula platyphylla had the highest C/Pand N/P ratios.4)The correlation analysis showed that there was a significant or extremely significant positive correlation between soil pH,soil moisture content and soil nutrients;there was also a significant or extremely significant positive correlation between available nutrients and total nutrients.

Key words: mountain areas of northern Hebei, rhizosphere soil, tree species, chemical property
