Study on Habitat Survey of Leccinum aurantiacum (Bull.) Gray of Beitun in Xinjiang

The character of vegetation,the soil physical and chemical properties and growth environment of Leccinum aurantiacum（Bull.） Gray of Beitun in Xinjiang province were primarily studied.The results showed the ecological condition suitable for Leccinum aurantiacum（Bull.） Gray occurrence was 450 m～600 m altitude where the forest was mainly Populus alba L.,canopy density was about 0.7,tree age was 20～40 years,breast diameter was 25 cm～45 cm.The acid soil were suited to the Leccinum aurantiacum（Bull.） Gray fruiting body with 0～20 cm,in which the soil water content was about 20%,and soil temperature was about 19℃.Organic matter content,effective N content and effective K content was average,and the total N content and effective P content was high with the value of 0.44 g·kg-1 and 9.77 mg·kg-1.
