摘　　要：To take full advantage of the natural hazel resources and improve its yield and quality in Great Xing’an Ridge region, we carried out an initial investigation. The result showed that: there are two species in this area: Corylus heterophlla and Corylus mandshurica. They mainly distribute from south of XinLin town, HuMa county, Heilongjiang province to south boundary of Great Xing’ an Ridge in mountain and hilly areas. Most of hazel in this area was under the state of natural growth with no scientific man-management. Soil where Corylus heterophlla grew was about 40 cm to 50 cm and Corylus mandshurica was 30 cm to 45 cm. The main plant disease was powdery mildew and insect pest were Curculio dieckmani, Zeuzera sp. and Faust Cockchafer. 100-seed weight of Corylus heterophylla was more than twice of Corylus mandshuria. However, Corylus mandshuria was plumper, had much more kernel and much less empty shell than Corylus heterophylla, and what’s more, shell sickness of it turned to be significantly thinner than Corylus heterophylla, all of which showed great cultivation value and economic commodity value.To take full advantage of the natural hazel resources and improve its yield and quality in Great Xing’an Ridge region, we carried out an initial investigation.
