Bud grafting method of Ulmus pumila cv.jinye in cool weather

Abstract

The invention relates to a new Ulmus pumila cv.jinye bud grafting technique, in particular to an Ulmus pumila cv.jinye cold bark bud grafting technique capable of breeding seedlings in idle days in winter. The method employs a 'T'-shaped bud grafting method which is characterized by grafting in early March to early May (March 1 to May 10) to improve the growth amount of Ulmus pumila cv.jinye seedlings in the current year. The method solves the problems that the grafting time of the traditional grafting methods is in more than one month from early July to late August, the grafted seedlings canusually be taken as semi-finished seedlings or be germinated to grow into finished young seedlings, grafting positions do not easily heal or scion germination can not be fully lignified if the grafting time is too late, and the seedlings are easily frozen to death or drained.

Description

Grafting method of cold sticky skin of Ulmus chinensis technical field The invention relates to a new bud grafting technology of Ulmus chinensis, in particular to a cold sticky skin bud grafting technology of Ulmus chinensis which can carry out seedling breeding in winter slack. Background technique Grafting is one of the methods of artificial vegetative propagation of plants. That is to graft the branches or buds of one plant onto the stem or root of another plant, so that the two parts connected together grow into a complete plant. Grafting is carried out by utilizing the ability of plants to heal after injury. During grafting, the cambiums of the two injured surfaces are brought close together and tightly bound together. As a result, due to cell proliferation, they heal each other and become a whole connected by vascular tissues. Grafting can be classified in many ways. According to the scion material can be divided into: ① branch grafting. It is mainly carried out ...

Problems solved by technology

The object of the present invention is just to provide a kind of grafting technique of cold sticky skin bud grafting of Ulmus chinenseensis, which solves the traditional grafting method. It can be used as semi-finished seedlings or germinate into young finished seedlings, and if the grafting time is too late, the grafted parts will not be easy to heal or the scion germination will not be fully lignified, and it is easy to freeze to death or dry out in winter
