Problems solved by technology

In the southern part of my country, walnut grows vigorously, with small branch angles, all kinds of branches are easy to be bare and out of joint, the crown is empty, there are few fruiting parts, the quality of flower bud differentiation is not good, late fruiting, serious flower and fruit drop, and low yield, etc., seriously restrict the southern region. Healthy and rapid development of regional walnut industry
The short branches (about 5-30 cm in length) in walnut are the main body of the fruit, but many annual shoots of walnut trees in the southern region grow to 1.5-4 meters, and they stop growing later. They are suitable for cultivating and expanding the crown and are not easy to form flower buds; When the walnut tree is large, the vigorous growth of the branches will easily lead to the airtightness of the canopy and affect the ventilation and light transmission, which will aggravate the damage of diseases and insect pests and is not conducive to flowering and fruiting

Embodiment 1

[0028] A method for cultivating subsectioned walnut branches suitable for southern regions, comprising the following steps:

[0029] (1) Pulling branches and engraving buds: Use a plastic rope or a branch puller to pull the base angle of the large or long branches of the walnut to 80°. The length of the large or long branches is the branch tip greater than 40cm. The bald part is cut to the xylem, and the hair branch is applied, and the hair branch is divided into two parts, one part of the hair branch is applied to the cut part, and the other part of the hair branch and water is applied to the root;

[0030] To apply Fajirin on the incised wound is to first apply a layer of Fajirin to the wound and wait for it to dry naturally, then wrap it with water-absorbing material, dilute it to 2 times its volume, and then spray it on the water-absorbing material; Applying to the root with water is to dilute the hair branch 5 times with water, insert a catheter 25cm away from the tree ro...

Embodiment 2

[0036] A method for cultivating subsectioned walnut branches suitable for southern regions, comprising the following steps:

[0037] (1) Pulling branches and engraving buds: Use a plastic rope or a branch puller to pull the base angle of the large or long branches of the walnut to 95°. The length of the large or long branches is greater than 40cm. The bald part is cut to the xylem, and the hair branch is applied, and the hair branch is divided into two parts, one part of the hair branch is applied to the cut part, and the other part of the hair branch and water is applied to the root;

[0038] To apply Fajirin to the incision site is to first apply a layer of Fajirin to the wound and wait for it to dry naturally, then wrap it with water-absorbing material, dilute it to 5 times its volume, and then spray it on the water-absorbing material; Applying to the root with water is to dilute the hair branch 30 times with water, insert a catheter 50cm away from the root, and pour the di...

Embodiment 3

[0044] A method for cultivating subsectioned walnut branches suitable for southern regions, comprising the following steps:

[0045] (1) Pulling branches and engraving buds: Use a plastic rope or a branch puller to pull the base angle of the large or long branches of the walnut to 85°. The length of the large or long branches is the branch tip greater than 40cm. The bald part is cut to the xylem, and the hair branch is applied, and the hair branch is divided into two parts, one part of the hair branch is applied to the cut part, and the other part of the hair branch and water is applied to the root;

[0046] To apply Fajirin on the incision site is to first apply a layer of Fajirin to the wound and wait for it to dry naturally, then wrap it with water-absorbing material, take the hairjirin and dilute it to 3 times the volume, and then spray it on the water-absorbing material; Applying to the root with water is to dilute the hair branch 10 times with water, insert a catheter 30...

Abstract

The invention discloses a sectional type walnut shoot culture method suitable for South China. The method includes the following steps of (1), branch stretching, bud notching and branching agent coating, wherein the basal angle of a walnut bough or long shoot is stretched to 80-95 degrees, the bald portion of the walnut shoot is carved to the xylem, the carved portion is coated with a branching agent, it is promoted that a bud germinates on the carved portion, and then the bud grows into a shoot; (2), first pinching, wherein when the walnut shoot grows to be 50-60 cm, the tender tip portion being 12-18 cm on the top of the shoot is picked off; (3), second pinching, wherein 20-30 days after first pinching, pinching is carried out again when the shoot grows to be 50-60 cm, and the tender tipportion being about 15 cm on the top of the shoot is picked off; (4), third pinching, wherein 20-30 days after second pinching, pinching is carried out again when the shoot grows to be 40-50 cm, andthe tender tip portion being about 15 cm on the top of the shoot is picked off. The problems that in South China, walnut shoots vigorously grow, bearing branches are fewer, the flower bud differentiation quality is poor, and late fruiting is generated are solved.

Description

technical field [0001] The invention relates to the technical field of agricultural cultivation, in particular to a segmented walnut shoot cultivation method suitable for southern regions. Background technique [0002] Walnut (JuglansregiaLinn.) is a deciduous tree of Juglans genus Juglans. It is one of the four largest nuts in the world and is also an important woody oil crop. In the southern part of my country, walnut grows vigorously, with small branch angles, all kinds of branches are easy to be bare and out of joint, the crown is empty, there are few fruiting parts, the quality of flower bud differentiation is not good, late fruiting, serious flower and fruit drop, and low yield, etc., seriously restrict the southern region. The healthy and rapid development of the regional walnut industry. The short branches (about 5-30 cm in length) in walnut are the main body of the fruit, but many annual shoots of walnut trees in the southern region grow to 1.5-4 meters, and they st...
