Embodiment 1

[0020] Carry out re-grafting to the surviving Kudingcha grafted tree of high position grafting (grafting height 20cm~25cm) in the spring of that year, and the steps are as follows:

[0021] A. Remaining rootstock sprouts: on the rootstock below the scion that has been grafted and survived, keep 1 sprout that grows better, and all the other sprouts are removed.

[0022] B. Rootstock cutting: Grafting in September, cut off the top of the rootstock sprouts, leaving an appropriate height, cut a vertical section with a length of 1.5cm to 2.5cm from bottom to top on the upper end of the sprouts towards the scion, and cut the back Cut a 0.5cm long oblique cut on the upper end.

[0023] C. Scion cutting: towards the direction of the sprout, at the same height as the cut on the upper end of the sprout, first obliquely cut a knife to a depth of 2mm in the xylem (the intersection angle with the scion is about 60°), and then cut one 1.5cm long from bottom to top ~2.5cm longitudinal secti...

Embodiment 2

[0028] The ear-stock reverse grafting was performed on the surviving plants grafted from the annual seedlings of sassafras.

[0029] A. Stay and raise rootstock sprouts: same as embodiment one.

[0030] B. Grafting time: Grafting in June.

[0031] C. rootstock and scion cutting: with embodiment one.

[0032] D. Grafting, binding and cultivation management: the same as in Embodiment 1.

[0033] The survival rate of the grafting method is 91%, which is 35% higher than that of the control; the growth amount is increased by 23%.

Abstract

The invention relates to a plant grafting method adopting reverse grafting of a scion and a root stock. The plant grafting method is characterized by comprising the following steps of reserving a root stock coppice shoot good in growth on a plant which survives after grafting is completed by a conventional grafting method, then respectively cutting seams in the coppice shoot of the plant and the scion, enabling the seam of the coppice shoot to be aligned with and tightly attached to the seam of the scion so that the coppice shoot is grafted to the scion, and tying the coppice shoot and the scion which are grafted for cultivation. The grafting method is particularly suitable for high position grafting and grafting of tree species which are slow in growth vigor and poor in seam healing properties. According to the plant grafting method disclosed by the invention, the coppice shoot of the root stock can be utilized for promoting the growth of the scion, and the situations that the seam of the root stock dies and further the survival of the scion is influenced due to coppice shoot elimination can be avoided; and besides, the new plant of the scion can also grow firmly on the root stock, and wind and snow harm is reduced and avoided.

Description

technical field [0001] The present invention relates to the grafting method of woody plants, especially a kind of method of grafting the shoots of rootstock on the scion, so as to improve the survival and preservation rate of grafting and promote the grafting method of growth. Background technique [0002] There are many grafting methods and types of woody plants. According to the height of the grafting part, there are two types: high grafting and low grafting; according to the nature of the scion, it can be divided into branch grafting and bud grafting; among them, the grafting method based on branch grafting includes cut grafting, split grafting, abdominal grafting and butt grafting. And plug skin connection and other methods. [0003] But all grafting methods in the past, from the relation between scion and rootstock, all can be referred to as positive grafting, promptly they all are that scion is grafted on rootstock, rather than opposite. [0004] The above grafting m...
