摘要
适宜的嫁接技术是钻天松繁育的最佳手段。研究表明,影响嫁接成活率的因素较多,7月下旬至8月中旬嫩枝嫁接比春季硬枝嫁接效果更为理想;天气、砧木不同嫁接部位都对嫁接成活率影响很大,而不同的嫁接人群、一天中不同的嫁接时间基本上不会对嫁接产生影响。
The suitable grafting technique is the optimal means for breeding Pinus sylvestris var.fastigiata(Carr.) Q.F.Anet.Study shows that: factors affecting the survival rate of Pinus sylvestris var.fastigiata(Carr.) Q.F.Anet are more;the result is more ideal by using softwood to graft in late July to mid-August than that by using hardwood to graft in spring;weather and different rootstocks in grafted parts have great influences on survival rate;different people engaged in grafting,different grafting time of one day has basically no influence on grafting.
