| 摘 要： | 通过对大兴安岭天然平榛进行系统调查分析,结果表明:榛树的年龄、密度、坡度、坡向、土壤厚度和森林郁闭度对结实均有不同影响。最佳结实年龄为3~5年生,最佳密度12万~25万株·hm~(-2),坡度一般小于10°,最好小于5°的阳坡或半阳坡,森林郁闭度小于0.2,土壤厚度大于20cm的榛林产量最高,可达196.7kg·hm~(-2)。

| Abstract: | Through the investigation on Corylus heterophylla in Daxing'anling,result shows that the age,density,slope,aspect,soil thickness and forest canopy density have significant effects on Corylus heterophylla seedlings.The optimal fruiting age and density is 3-5 a & 12-25 million trees·hm-2;slope is generally less than 10 degrees,preferably less than 5 degrees on sunny or semi-sunny slope;forest canopy closure is less than 0.2;soil thickness is more than 20 cm,such Corylus heterophylla plantation can obtain the the highest yield,up to 196.7kg·hm-2. |
