Embodiment Construction

[0015] As shown in Figures 1, 2, and 3, a walnut "T"-shaped budding method includes selection of the budding site and incision operation, bud cutting, bud insertion and interface treatment, and binding of the budding site. The specific steps are as follows: :

[0016] (1) Selection of budding site and incision operation:

[0017] ① Select the smooth part on the rootstock 1 within 10-30 cm from the ground as the budding site, leave two compound leaves at the upper end of the budding site and cut off the upper part, and select two-year-old walnut seedlings for the rootstock 1.

[0018] ②Cut across the budding part of the rootstock to the xylem, with a length of about 1.5 cm, and make a longitudinal cut in the middle of the cross cut to the xylem, with a length of 3-3.5 cm, forming a "T"-shaped incision 2.

[0019] (2) Cutting of budding:

[0020] ①Select the well-developed and mature branches of the current year as the scion 4, cut off the petiole, and require full buds and sm...

Abstract

The invention relates to a T-shaped bud grafting method for walnuts, which belongs to the grafting technology of the asexual propagation of the walnuts. The method comprises the steps of selecting and cutting a bud grafting part, cutting a scion bud, inserting the scion bud, treating a grafting opening, and binding the bud grafting part. Compared with the prior art, during the process of the grafting opening treatment, a flow guiding opening (5) is cut below the grafting opening, so as to enable bleeding sap to flow out of the flow guiding opening (5), therefore the problem that the bleeding sap erodes the scion bud slice in the other grafting methods is overcome, and the survival rate is remarkably improved and is more stable.

Description

technical field [0001] The invention relates to a fruit tree cultivation technique, in particular to a budding technique in the technical field of walnut asexual propagation. Background technique [0002] Walnut is an important economic forest tree species worldwide. Because of its unique economic value and nutritional health value, it has been valued by people for a long time. my country has a long history of walnut cultivation. Due to long-term seed propagation, the yield is low and the quality is poor. Although my country's walnut breeding and cultivation experts have cultivated a series of new walnut varieties for nearly half a century, the degree of walnut variety has been greatly limited due to poor asexual reproduction technology. [0003] Grafting is the main method of breeding improved walnut varieties, and the survival rate of grafting is an important factor affecting the breeding speed of improved walnut varieties. Over the years, many experts and scholars have...
