Problems solved by technology

[0002] The existing walnut tree high-branch replacement method is complicated to operate, difficult to master, difficult to popularize, and difficult to popularize, mainly because it is not suitable for the masses with relatively little professional knowledge, poor basic skills, and relatively strong simple hands-on ability. The grafting survival rate of the existing walnut high-branch replacement method is generally extremely low, which has greatly weakened the enthusiasm, consciousness and initiative of the walnut planting masses to engage in walnut tree cultivation to some extent

Embodiment 1

[0025] Walnut high-branch replacement method of the present invention, its steps are:

[0026] a. The selection and processing of scion: the scion should select the strong and full 1-year-old branch of the middle and upper part of the mother tree with good local habitat quality or use the above-mentioned branches to graft the 1-year-old strong and full branch of each part of the living tree; cut it off before the tree germinates, and the The branches are quickly dipped in the paraffin wax mixture solution heated to boiling in a water bath, so that the branches are evenly covered with a very thin layer of paraffin wax. Store it in a cool and ventilated room, avoid sunlight, if there is a constant temperature cold storage, it is best to store the sealed branches in it;

[0027] b. Grafting time control: it can be carried out from the beginning of rootstock sprouting to the growth of small buds within 5cm;

[0028] c. The selection of the grafting site: according to the speci...

Embodiment 2

[0036] The grafting cultivation method of walnut tree of the present invention, its steps are:

[0037] a. The selection and processing of scion: when scion, select the strong and substantial 1-year branch of the upper part of the excellent mu tree in the local habitat or use the above-mentioned branches to graft into the 1-year-old strong and substantial branch of each part of the living tree; The branches are heated in a water bath to boiling paraffin mixed solution and dipped quickly, so that the branches are evenly covered with a very thin layer of paraffin wax. Store them in a cool and ventilated room to avoid sunlight. If there is a constant temperature cold storage It is best to store the sealed branches in it;

[0038] b. Grafting time control: it can be carried out from the beginning of rootstock sprouting to the growth of small buds within 5cm;

[0039] c. Selection of grafting parts: According to the actual situation of the tree to be transformed, choose the str...

Embodiment 3

[0047] a, scion cutting system. Choose branches whose pith does not exceed 1 / 2 of its diameter for cutting. When cutting, be sure to cut a length of not less than 8cm on the opposite side of the desired bud, and not less than 2cm for the steep part; the near-rectangular part that needs to be inlaid is not less than 5cm, and the tip of this part is only nearly 1mm For the left and right woody layers, the near-rectangular part that needs to be inserted into the rootstock must be smooth and straight, that is, the cut scion insertion part must be long, flat and thin, and the two sides of the cut near-rectangular part need to be The extremely thin skin is peeled off a little bit. The purpose of doing like this is exactly to have reduced the distance that the callus tissue contacts between scion and rootstock as far as possible. In other words, the rootstock and the scion only need to grow separately so that a small amount of callus can contact and fuse with each other, and soon p...

Abstract

A high-efficiency high-branch replacement method for walnut trees relates to a method for transforming and cultivating large crop trees, in particular to a high-efficiency high-branch replacement method for walnut trees. In the grafting process of the present invention, each saw cut can be inlaid with two or more buds, and the grafting survival rate based on this method is extremely high, and each saw cut will be healed within 1-2 years after grafting. The walnut tree grafted by this method has a very high survival rate, and the shoots after survival are extremely vigorous, the structure is extremely stable, and the essence of early fruit bearing lies. The walnut trees grafted by this method usually begin to test flowers and bear fruit in the second year after grafting, and enter the high-yield period with numerous fruits in the fifth year, and their early fruit and high-yield performances are outstanding.

Description

technical field [0001] The invention relates to a method for transforming and cultivating large trees of agricultural crops, in particular to a high-efficiency high-branch replacement method for walnut trees. Background technique [0002] The existing walnut tree high-branch replacement method is complicated to operate, difficult to master, difficult to popularize, and difficult to popularize, mainly because it is not suitable for the masses with relatively little professional knowledge, poor basic skills, and relatively strong simple hands-on ability. The graft survival rate of existing walnut high-branch replacement method is generally extremely low, which has greatly weakened the enthusiasm, consciousness and initiative of the walnut planting masses to be engaged in walnut tree cultivation to some extent. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art, to provide a kind of walnut tall branch which is e...
