Problems solved by technology

However, for the propagation of trees that lack suitable affinity rootstocks, they only rely on ramets, layering, root tillers, etc. for propagation, which has a low propagation coefficient and poor uniformity of seedlings, which is not suitable for production needs.

Embodiment Construction

[0019] Below in conjunction with accompanying drawing and embodiment, further elaborate the present invention. In the following detailed description, certain exemplary embodiments of the invention are described by way of illustration only. Needless to say, those skilled in the art would realize that the described embodiments can be modified in various different ways, all without departing from the spirit and scope of the present invention. Accordingly, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0020] A seedling grafting propagation method, comprising the following steps:

[0021] Step one, such as figure 1 As shown, choose rootstock 1, choose the scion 2 of seedling to be grafted, then scion 2 is grafted on the rootstock 1, smear auxin, such as rooting agents such as naphthalene acetic acid, at the junction of scion 2 and rootstock 1;

[0022] Step two, such as figure 2 As shown, after the scion 2 grows in...

Abstract

The invention discloses a seedling grafting breeding method. The seedling grafting breeding method comprises step 1, selecting root stock, selecting a scion of a seedling to be grafted and grafting the scion on the root stock; step 2, transplanting and planting the scion after the scion grows into a finished product seedling, performing deep planting on the finished product seedling during the planting and completely covering the combination position of the scion and the root stock with soil; step 3, cutting off the root stock after the combination position of the scion and the root stock roots and only reserving the scion and a self-root on the scion. The seedling which is bred by the seedling grafting breeding method has the self root and is free of the root stock and accordingly the self-root seedling can be bred rapidly and the breeding coefficient is improved.

Description

technical field [0001] The invention relates to the technical field of plant propagation, in particular to a self-rooted seedling propagation method. Background technique [0002] Grafting and propagating tree species with suitable rootstocks is an effective propagation method for most trees. Its advantages are high propagation coefficient, simple operation, low cost, and small variation in genetic traits. Yet for the tree propagation that lacks suitable affinity rootstock, then only rely on branch, layering, root tiller etc. to propagate, its propagation coefficient is low, and seedling uniformity is poor, does not adapt to production needs. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a seedling grafting propagation method with high survival rate and neat seedling stock. [0004] In order to solve the problems of the technologies described above, the technical solution of the present invention is: a seedlin...
