| 摘 要： | 通过对大兴安岭天然平榛潜在结实能力进行的分析,结果表明:大兴安岭天然平榛有较高的潜在结实能力,最高可达1 304kg hm~(-2),是天然状态下实际结实量(200kg hm~(-2))的6.5倍,具备经营条件。最佳结实年龄是3-5年生,6年生以后结实开始下降;最佳密度因年龄不同有所不同,3年生结实量为15万~25万株 hm~(-2),4~5年生为11万~19万株 hm~(-2)。

| Abstract: | Potential yielding of natural Corylus heterophylla in Daxing 'anling were analyzed.Result shows that: Daxing'anling natural Corylus heterophylla has a high potential yielding capacity, up to 1 304 kg hm-2, is 6.5 times as much as the natural state of the actual strength (200 kg hm-2), with operating conditions.The optimal age is from 3 to 5 years old, the yielding begin to decline after 6 years;the optimal density varies due to age, the density for 3-year-old Corylus heterophylla is from 15 million hm-2 to 25 million hm-2;the density for 4-5-year-old Corylus heterophylla is from 11 million hm-2 to 19 million hm-2. |
