Arborvitae wax-sealing double-tongue grafting seedling raising process

Abstract

The invention discloses an arborvitae wax-sealing double-tongue grafting seedling raising process. In the process, a container seedling in reserved bed seedlings or transplant seedlings of arborvitae is adopted as a stock, a 2 to 3 year-old twig with robust growth, plump buds and no plant diseases or insect pests is adopted as a scion, a problem that the scion is easy to lose water is solved by the wax-sealing technology, and a problem of enlarging grafting combination area is solved by the double tongue grafting technology. By adopting the method, the arborvitae grafting seedling raising canbe directly carried out in field, corresponding seedling raising procedures are simplified, the cost is low, the seedling raising is quick and the survival rate is high. The method can solve the problem of quick propagation of good provenance, family, clone and good single seedling of the arborvitae.

Description

technical field [0001] The invention belongs to the technical field of grafting and raising seedlings in the cultivation of woody plant seedlings, in particular to a technique for grafting and raising seedlings of arborvitae wax-sealed double-tongue grafting. Background technique [0002] Arborvitae (Platycladus orientalis) belongs to Cupressaceae, Arborvitae genus, and is an evergreen tree. Because of its good resistance and adaptability, it is not only widely used in landscaping, but also a pioneer tree species in barren hills greening in my country. In my country, from Inner Mongolia and Jilin in the north, to Guangdong and northern Guangxi in the south, the footprints of artificial cultivation of oriental cypress can be seen everywhere. As a kind of tree species that is widely used in production, seedling cultivation method of Arborvitae mostly adopts seedling cultivation method. Although there are also reports on grafting cultivation, there are generally only tradition...

AI Technical Summary

Problems solved by technology

As a kind of tree species that is widely used in production, seedling cultivation method of Arborvitae mostly adopts seedling cultivation method. Although there are also reports on grafting cultivation, there are generally only traditional methods such as split grafting, docking grafting, bag grafting, etc., and have been reported at home and abroad. The following deficiencies obviously exist in the grafted and raised seedlings of arborvitae: (1) the grafting must be carried out in greenhouses and greenhouses, which requires high environmental conditions, and the cost of protection facility construction is high, which is not easy to promote; (2) the scion is not sealed with wax, which is extremely It is easy to cause death due to transpiration and dehydration; (3) during operation, first graft in a greenhouse, and then carry out field transplantation, and the grafting position is required to be carried out at the base of the rootstock, and the operation procedures are many and complicated, thereby increasing the cost of grafted seedlings

The problems mentioned above have limited the production and application of grafted seedlings of orientalis to a certain extent.

So far, there is no report on the method of grafting arborvitae seedlings with high survival rate without using shading measures, directly carrying out in the field, adopting wax-sealed scion and double tongue grafting technology simultaneously, and the present invention is exactly under such technical background Proposed
