Breeding method for clove grafting

Abstract

The invention relates to a breeding method for clove grafting, which mainly comprises the following steps: taking wild shrub Shanceli as rootstock and pure clove branches as scions for grafting; taking and scissoring the pure clove branch with the length of 3-5 cm; whittling a scion whittling surface with the length of 3-4.5 cm and the depth to a pith heart center on one side at the lower end of the branch; whittling an inclined surface with the length of about 1 cm on the other side at the lower end of the branch; then taking the wild Shanceli as rootstock, cutting a cutting surface with the length of 3-5 cm and the depth to xylem on the rootstock, and cutting a rootstock cut corresponding to the scion inclined surface at the lower end of the cutting surface of the rootstock; tightly bundling the rootstock and the branch by using a binding band used for grafting correspondingly, and breeding and managing the rootstock and the branch. The breeding method has high survival rate and fast growth, and the grafted clove has strong adaptability to climate and soil, strong vitality and disease-resistant capability, increased flower buds and prolonged blooming period.

Description

technical field

[0001] The invention relates to a grafting breeding method of cloves, in particular to a grafting breeding method for producing fine clones and fine lilac seedlings. Background technique

[0002] At present, cloves are cultivated all over our country, mainly in Zhejiang, Anhui, Shandong and other places. Lilac has a fragrant smell and is deeply loved by the people. Lilac is not only used as an ornamental plant, but its fruit can also be used as a condiment for cooking food. Therefore choose a good grafting breeding method to prolong its flowering period and improve its flower-producing power to become the key. There are many grafting methods now, but they are highly targeted and have relatively large limitations. For example, the bud grafting method needs to graft the twigs within half a month around the middle of May, and the cortex of the rootstock needs to be peeled off during grafting. The splitting method is mainly to cut the rootstock transversely, ma...
