西伯利亚红松嫁接技术试验

摘要

以西伯利亚红松为接穗，进行了不同砧木（樟子松，红皮云杉）、嫁接时间（4月上、中、下旬，5月上、中、下旬）、嫁接方式（劈接、芽接、插皮接）、保湿处理（石化剂、黄蜡液、塑料袋）等措施对西伯利亚红松嫁接成活率的影响研究，结果表明：以樟子松作砧木，芽接成活率最高，达80％以上；嫁接时间选在春季4月上旬为好，成活率达91．7％；3种保湿处理嫁接成活率均达90％以上，显著高于对照，以黄蜡液封膜效果最好。%Taking Pinussibiricaasscion,differentrootstocks(Pinussylvestrisvar.mongolica,Piceakoraiensis), grafting time (upper ,middle & late April ,upper ,middle and late May) ,grafting methods (cleft grafting ,bud graft-ing ,bark grafting ) ,moisturizing treatment (petrochemical agents ,yellow wax liquid ,plastic bags) on survival rate of Pinus sibirica were studied .Result shows that :taking Pinus sylvestris var .mongolica as rootstocks ,survival rate are the highest by taking budding ,being above 80% ;grafting time should be selected in the early April in spring ,the survival rate being 91 .7% ;the grafting survival rate of three kinds of moisturizing treatments which are significant higher than the control ,being over 90% ;the optimal method is yellow wax liquid to seal film .
