Embodiment 1

[0023] Embodiment 1 discloses a kind of method for rapid rooting and seedling raising of mulberry branches, comprising the following steps:

[0024] Step 1. Incision

[0025] Such as figure 1 As shown, 50-60 days before the cutting of the mulberry tree, cut a crescent-shaped incision with a knife along the bud base at 3-5cm above the base of the branch 1, and then cut another incision of the same size on the opposite side of the crescent-shaped incision. The length of the shaped incision is 5mm, the height is 1mm, and the depth is just to reach the xylem; every 2-3 buds along the branch, repeat the above incision step;

[0026] Step 2. Incision processing

[0027] Apply rooting agent at the otch in step 1 with a writing brush, the rooting agent in embodiment 1 is the mixed solution that the concentration that is deployed into by indole acetic acid, indole butyric acid, ABT rooting powder and naphthalene acetic acid is 20ppm. After coating, wrap the cuts with rooting substra...

Embodiment 2

[0033] Embodiment 2 discloses a method for rapid rooting and seedling raising of mulberry branches. About 2 months before the cutting of mulberry branches, at 5 cm from the base of the branches, below the base of the buds, a crescent-shaped incision is carved with a knife along the base of the buds. The diameter should be 10mm in length and 5mm in height, and the depth should be just to the xylem, not too deep or too shallow; cut another roughly the same incision on the opposite side of the incision, and the total length of the incision should not exceed the circumference of the branch at the incision. Half of the length is appropriate. At the same time, in order not to affect the nutrient transport of the branches, it is not suitable to cut directly under the mulberry leaves on both sides of the cut. After cutting a place, separate 3 buds along the branch, select the bud that is in a straight line with the original cut, and cut again in the same way above at the base and on th...

Embodiment 3

[0035] Embodiment 3 discloses a kind of rapid rooting and seedling raising method of mulberry branches, 2 months before the cutting of mulberry branches, at 3 cm from the base of the branches, below the base of the buds, a crescent-shaped incision is carved with a knife along the base of the buds, according to the position of the branches at the incision position Diameter, length 5mm, height 1mm, depth just to the xylem, should not be too deep or too shallow; cut another roughly the same incision on the opposite side of the incision, the total length of the incision should not exceed half of the circumference of the branch at the incision At the same time, in order not to affect the nutrient transport of the branches, it is not suitable to cut directly under the mulberry leaves on both sides of the cut. After cutting a place, separate 2 buds along the branch, select the bud that is in a straight line with the original cut, and cut again in the same way at the base and on the op...

Abstract

The invention discloses a rapid rooting seedling-raising method for mulberry branches. The method comprises the following steps: about 2 months before branches of a mulberry tree are cut, a crescent-shaped cut is cut along the bud base part at a distance of 3-5 cm from the branch base part, and a same cut is cut at the opposite of the cut; a bud located in a same straight line with the original cut is selected every 2-3 buds upwards along the branch, and cutting is performed along branches according to the above same method at the base part and opposite side of the cut; a rooting agent coats the cut place, the cut is wrapped by using a rooting substrate, the substrate is wrapped by using a black-white film, and the upper and lower parts are fixed by using a self-locking nylon cable tie; and after 50-60 days, branch cutting in a mulberry filed is combined, a mulberry seedling is taken to a prepared field, the self-locking nylon cable tie is cut, the black-white film is removed, and themulberry seedling with the substrate is planted into soil. The method provided by the invention has the advantages of a short seedling-raising period, high seedling-raising efficiency, no influence ona yield of mulberry leaves in a current season, a high rooting rate and a high survival rate of transplantation, and has the advantages of a simple process, not high operation skill requirements andconvenient promotion to farmers.

Description

technical field [0001] The invention relates to a method for rooting and raising seedlings of branches, in particular to a method for rapidly rooting and raising seedlings of mulberry branches. Background technique [0002] Mulberry trees are perennial, broad-leaved, and deciduous plants. The mulberry trees we cultivate for silkworm cultivation mainly have high-yield and high-quality mulberry leaves. Because mulberry trees are cross-pollinated plants, in order to better maintain some of their excellent traits, generally Cultivate mulberry seedlings by asexual reproduction. The methods of asexual reproduction of mulberry include grafting, cutting, layering, tissue culture, etc., but generally more grafting is used in production, and cuttings are used in a few areas to raise seedlings. Grafting and raising seedlings generally takes 2 years, that is, the first year must be sown to produce rootstocks, the grafting will be completed in the spring of the next year, and the seeds ...
