New euonymus hamiltonianus species grafting seedling culture method

Abstract

The invention provides a new euonymus hamiltonianus species grafting seedling culture method, and relates to a technical method of rapidly and efficiently propagating new seedling species. The new euonymus hamiltonianus species grafting seedling culture method mainly resolves the problems that new euonymus hamiltonianus species have few sowing and propagation resources, grow slowly and have high culturing cost; a cutting propagation coefficient is low, and the period is long; grafting propagation scions lose water easily and have the small combination area, out-of-season grafting and storage are difficult, and the rate of survival is low when direct upper top-grafting is conducted on the scions. The method comprises the steps that (1) stocks are selected and processed; (2) the scions are selected; (4) double tongue grafting is conducted; (5) the scions are wax-sealed; (6) storage in sand, moisture preserving and heeling in temporary planting are conducted. The method uses the scion wax-sealing technique, double tongue grafting technique, the storage in sand, moisture preserving and heeling in temporary planting technique and the like, has the advantages of being short in culture period, high in propagating coefficient, low in labor cost and the like, and can be used for grafting propagation of different species of euonymus hamiltonianus.

Description

technical field [0001] The invention belongs to the technical field of grafting and raising seedlings in the cultivation of woody plant landscaping seedlings, and in particular relates to a method for anti-seasonal double-tongue grafting of a new silk cotton wood variety. Background technique [0002] Silk cotton wood Euonymus maackii belongs to the genus Euonymus of the family Euonymus, also known as Euonymus maackii, Mingkai Yehe, Baidu, a small tree, up to 6 meters. It is a native tree species in North China, with a wide distribution area. It is distributed in all provinces and regions except Shaanxi, Southwest China and Guangdong and Guangxi, but it is often cultivated in the south of the Yangtze River. It has the advantages of cold resistance, drought resistance, salt and alkali resistance, and extensive management resistance. It is an important ornamental tree species and is suitable for cultivation in arid and cold areas. In recent years, silk cotton wood has been wi...

Problems solved by technology

[0003] The purpose of the present invention is to provide a complete set of high-efficiency and practical, high survival rate, in view of the insufficient number of scions in the grafting of new varieties of silk cotton wood, the scion is easy to lose water, and the production cycle is too long. Direct planting, thus solving the rare problem that new varieties of silk cotton wood cannot be rapidly multiplied in large quantities
