摘要
[目的]解决挪威国王枫在引种中存在的种源稀少、种子发芽率低、实生苗性状分化严重等问题。[方法]观察挪威国王枫的生物学及生态学特性,对挪威国王枫的嫁接繁殖技术,如砧木选择、嫁接时间、嫁接方法、嫁接部位、砧木性质等进行研究,并对1年生挪威国王枫苗木的生长节律和5年生苗木的生长状况进行测定。[结果]挪威国王枫具有耐寒、耐旱、抗高温、耐盐碱等优良特性。元宝枫、五角枫和长柄槭均可以作为挪威国王枫的嫁接砧木使用,其中以春季低接元宝枫效果最好。挪威国王枫在河南平原地区表现出了速生特性,1年生嫁接苗高达1.71m,地径达1.8cm;5年生嫁接苗高达6.56m,胸径达7.08cm。[结论]挪威国王枫可以作为河南平原地区及其相似生态类型区的彩色园林树种进行繁殖和应用。利用乡土树种元宝枫、五角枫等作砧木,采用嫁接方法来繁殖挪威国王枫是一种简便易行的方法。
[Objective] The research aimed to solve the introduction problems of Norway A.platanoides‘Crimson King’,including rare provenances,low seed generation percentage and severe seedlings differentiation.[Method] The biological and ecological properties were observed.The experimental study was made on the technology of the grafting and the propagation,such as the choice and the property of the stock,the time,the method and the position of the grafting,the measurement was made on the growth rhythm of one year seedlings and the growth situation of 5 years.[Result]The results revealed Norway A.platanoides‘Crimson King’ had excellent characters of cold tolerance,drought tolerance,high temperature resistant and saline alkali tolerance.A.truncatum Bunge,A.mono Maxim and A.Longipes Franch ex Rehd all can be used as stock of it,but A.truncatum Bunge was the best.From the time,the springtime was the best.Norway A.platanoides‘Crimson King’ in Henan plain area showed the fast growing characters,in one year,the grafting seedlings can reach 1.71 m height,1.8 cm ground diameter.In 5 years,it can reach 6.56 m height,7.08 cm diameter at breast height.[Conclusion] Through the study,it can be found that Norway A.platanoides‘Crimson King’ can be used as colored landscape species in Henan plain area and ecological anology areas.Using A.truncatum Bunge,A.mono Maxim and et al as stocks,using grafting technology,Norway A.platanoides‘Crimson King’ can be propagated simply and easily.
