Problems solved by technology

[0002] Grafting is a commonly used method for asexual reproduction of fruit trees. Generally, it takes 3-4 years for grafted seedlings to emerge from the nursery, and it takes 3-4 years for the saplings to take shape after planting. Less labor cost, if the timing is not well grasped, the plastic surgery period will be missed, which is not conducive to the cultivation of the crown tree shape and early fruiting
As for citrus fruit trees, because they are susceptible to the damage of citrus greening disease, the productive years and lifespan of the trees are greatly shortened.
[0003] The commonly used fruit tree grafting method is to connect one bud with one anvil. After the first shoot of the bud grows mature, top it and dry it. Then select 2-3 shoots in different directions for the second shoot, and cultivate them in sequence. It takes at least 3 years from the beginning of grafting to form a basic tree shape of 3×3 shoots. It takes a long time to emerge from the nursery and start production, and the early yield is low.

Embodiment 1

[0020] Example 1 : Ponkan with three buds on one stock

[0021] 1) Experimental steps:

[0022] Select adult ponkan trees with good fruit quality, high yield, strong growth, no pests and diseases, and pure varieties as the female parent tree for ear picking, and cut spring or autumn shoots with full growth and full bud eyes in the middle and upper parts of the outer canopy, and cut off the leaves immediately after harvesting , leaving only the petiole, soaked with 1000ppm tetracycline hydrochloride for 2 hours and then rinsed with water. If grafting cannot be done immediately, wrap the scion with a damp cloth or plastic film.

[0023] Choose 1-2 years old, robust, 1cm-diameter Fructus aurantii seed stock, select the smooth side of the rootstock at a predetermined height during grafting, and use a grafting knife to make a vertical incision with the xylem slightly downward, about 2-3cm long.

[0024] Grafting period: September-October, 1996.

[0025] Grafting method: 15cm / 2...

Embodiment 2

[0035] Example 2 : Kumquat with three buds on one stock

[0036] 1) Experimental steps:

[0037] Select Yangshuo kumquat adult trees with good fruit quality, high yield, strong growth, no pests and diseases, and pure varieties as the female parent tree for ear picking. Cut off the spring or autumn shoots with full growth and full bud eyes in the middle and upper parts of the crown periphery, and cut off immediately after harvesting Leaf leaves, only the petioles are left, soaked with 1000ppm tetracycline hydrochloride for 2h and then rinsed with water. If it cannot be grafted immediately, wrap the scion with a damp cloth or plastic film, and store it naturally or in a refrigerator at 6°C.

[0038] Choose 1-2 years old, robust, Yangshuo kumquat seed stock with a diameter of about 1 cm. When grafting, select the smooth side of the root stock at a predetermined height, and use a grafting knife to make a vertical incision with the xylem slightly downward, about 2-3 cm long.

Abstract

The invention belongs to the technical field of fruit tree grafting and seedling cultivation and discloses a fruit tree three-bud grafting method. According to the method, three buds are grafted at three different heights in three different directions sequentially on a stock. The method includes the following steps of stock selection and treatment, scion acquisition, grafting period selection, grafting, bud insertion and binding, unbinding and bud removal, and pinching and shoot removal. Compared with a traditional single-bud grafting method, the fruit tree three-bud grafting method has the advantages that a crown which is put into production is formed one to two years earlier, seedling quality is improved, and the early yield can be increased.

Description

technical field [0001] The invention belongs to the technical field of grafting and raising seedlings of fruit trees, and in particular relates to a grafting method of one stock and three buds of fruit trees. Background technique [0002] Grafting is a commonly used method for asexual reproduction of fruit trees. Generally, it takes 3-4 years for grafted seedlings to emerge from the nursery, and it takes 3-4 years for the saplings to take shape after planting. Less labor cost, if the timing is not well grasped, the plastic surgery period will be missed, which is not conducive to the cultivation of the crown tree shape and early fruiting. As for citrus fruit trees, because they are vulnerable to citrus greening disease, the productive years and lifespan of the trees are greatly shortened. [0003] The commonly used fruit tree grafting method is to connect one bud with one anvil. After the first shoot of the bud grows mature, top it and dry it. Then select 2-3 shoots in diffe...
