雪松为我国园林绿化的珍贵树种,也是世界著名的观赏树种,但在自然受粉的条件下,饱满种子极少,很难获得实生苗,因而繁殖速度不能适应各方面的需要。扦插繁殖则受母树年龄效应的限制,一般用实生苗幼树枝条扦插,成活率较高,用扦插苗幼树枝条扦插则很难生根。且扦插繁殖从采穗到生根移栽时间需半年以上,工序繁琐,工作量大,管理不便,加之扦插苗在两三年内生长缓慢,若干年后保存率又不高,特别是扦插技术没有把握,管理不
Cedar is a precious tree species in our country and is also a world famous ornamental tree species. However, under the condition of naturally receiving powder, the seeds are very few and hard to obtain seedlings, therefore, the propagation speed can not meet the needs of all fields. Cutting propagation by the parent tree age effect of the restrictions, the general use of seedlings saplings cuttings, higher survival rate, cutting seedlings with young branches and cuttings it is difficult to root. And cutting propagation from ear to rooting transplanting time to be more than six months, tedious process, heavy workload, management inconvenience, combined with the growth of cuttings in two or three years slow, a few years after the preservation rate is not high, especially the cutting technology is not sure , Management is not
