Embodiment Construction

[0013] A rapid propagation method of Euonymus euphratica arborization, including grafting time selection, scion selection and preparation, grafting method and post-grafting management, the grafting method is: selecting silk cotton wood with a diameter at breast height of 15-25 cm or more. Rootstock, graft the Euonymus scion to 4-5 branches of silk cotton wood on the first-level branch of the height of silk cotton wood 5-6m. The present invention uses silk cotton wood with a DBH of 15-25 cm as rootstock after colonization, which shortens the cultivation time and advances the time for seedlings to enter the market.

[0014] Firstly, each branch to be grafted is processed, and a smooth cross-section is cut, and then a knife is cut vertically downward along the middle of the stem, and the depth is determined according to the length of the scion; The epidermis of the scion and the epidermis of the rootstock are well aligned, and the scion is cut and exposed to 0.2 cm, and then tied...

Abstract

The invention relates to the technical field of grafting for improving and optimizing plant varieties, in particular to a rapid propagation method for euonymus japonicus arborization, which includes grafting time selection, selection and preparation of cions, grafting method and post-grafting management. The grafting method is as follows: euonymus bungeanus, the diameter at breast height of which is more than 15cm to 25cm, is selected as a stock, and the euonymus japonicus cions are grafted on four to five primary branches of the euonymus bungeanus, which are at the altitude of 5cm to 6cm on the tree. The euonymus japonicus varieties are euonymus japonicus L. Cv. 'aureo-marginatus' and euonymus japonicus L. Cv. albo-marginatus. By means of the systematic growth management, the rapid propagation method for euonymus japonicus arborization increases the survival rate of seedlings, and broadens the range of growing the euonymus japonicus varieties, moreover, the time of putting seedlings into the greening market is greatly advanced, and thereby the market price of the seedlings is high, so that the economic benefit is high.

Description

technical field [0001] The invention relates to the technical field of plant variety improvement and optimized grafting, in particular to a rapid propagation method of arborization of Euonymus euonymus. Background technique [0002] Euonymus euonymus is an evergreen shrub or small tree, which is more cold-resistant. It is difficult to grow into tall stems because of its slow growth. It is often used as hedgerows and background planting materials in landscaping. It is native to southern Japan and is cultivated in all provinces in the north and south of my country. [0003] However, there are few evergreen trees with good landscape effects in the northern region, and evergreen broad-leaved trees that are resistant to pruning and easy to shape are rare, and the technology for arborization of Euonymus euonymus is not yet comprehensive. At present, there is an invention patent with the patent number 200510065833.7, which provides a cultivation technique using silk cotton wood as...
