陕西卫矛嫁接技术

The Grafting Technology of Euonymus schensianus Maxim.

本文从材料选择、采集,嫁接时间、嫁接方法、接后管理、病虫害防治等方面总结出一套适合卫矛栽培的高效嫁接技术。接穗选取陕西卫矛木质化程度良好的当年生或一年生健壮枝条,砧木一般选择米径3 cm以上的健壮丝棉木植株。采取插皮接的方法嫁接,从3月初至10月下旬均可进行,其中3月初嫁接成活率最高。嫁接成活后,及时开展放风、解绑,修剪以短截为主。病虫害防治方面,通过树干涂白减少树皮开裂,采取物理、生物及化学的方法综合防治卫矛巢蛾、丝棉木金星尺蠖等虫害。

Euonymus schensianus Maxim.is an excellent kind of ornamental plant with peculiar fruit and beautiful tree figure.This paper summarized a set of efficient grafting techniques suitable for production from the material selection,collecting and grafting time,grafting method,post-grafting management,pest control and so on.The current or annual strong branches with good lignification from Euonymus schensianus Maxim were selected as the scions and the strong Euonymus bungeanus plants which diameter at breast height is more than 3cm as the rootstocks.Grafting can be carried out from early March to late October,which the survival rate of grafting is the highest in early March.After surviving of grafting,ventilating and untying shall be carried out timely and pruning are mainly cutting back.In terms of pest control,the crack of trunks can prevent by white washing.Physical,biological and chemical methods are adopted to control comprehensively the pests such as Yponomeuta polystigmellus Felder and Calospilos suspecta Warren.
