Embodiment 1

[0033] In December 2017, 5-year-old, robust, no pests and diseases, no mechanical damage, and a thickness of 1.5 cm in the upper crown of the pickled walnut tree with 2 full and alternate leaf buds were selected as scions, which were cut into lengths below 20 cm. Branches and scions have been dried for 15 days (10°C) and soaked in wax solution (industrial paraffin and beeswax in a weight ratio of 10:1) at 62°C for 1 second. On March 1, 2018, the Guangxi Phoenix The 4-year-old local walnut varieties in Nongzhe Village, Fengcheng Town, Shanxian County were grafted at high positions. Cut the sawing plane of the rootstock into a "V" shape. The depth of the V is about 1 cm. A vertical drainage ditch about 10 cm long is opened on the outside of the "V" shape. The upper end of the drainage ditch is connected to the "V" shape. The outlet forms a "Y"-shaped drainage ditch up and down. Graft with the skin insertion method, use a grafting knife to draw an oblique annular drainage ditch a...

Embodiment 2

[0036] In January 2018, 4-year-old, robust, no pests and diseases, no mechanical damage, and a thickness of 1.4 cm in the middle and upper crown of the pickled walnut tree with 2 full and alternate leaf buds were selected as scions, which were cut into lengths below 25 cm. Branches and scions were dried for 10 days (10°C) and soaked in wax solution (industrial paraffin and beeswax in a weight ratio of 10:1) at 65°C for 1 second. On February 28, 2018, the Guangxi Capital The 3-year-old Yunxin No. 14 walnut variety in An County was grafted at a high position. Cut the sawing plane of the rootstock into a "V" shape. The depth of the V is about 1 cm. A vertical drainage ditch about 10 cm long is opened on the outside of the "V" shape. The upper end of the drainage ditch is connected to the "V" shape. Outlet, forming a "Y"-shaped drainage ditch up and down. Grafting with the skin insertion method, use a grafting knife to draw an oblique ring-shaped drainage ditch about 10 cm below t...

Abstract

The invention discloses a moisture regulation and control method for branch scion top grafting of juglans sigillata dode in the south. The method includes scion drying and wax sealing; providing a Y-shaped drainage ditch in a stock saw bite and providing an oblique annular drainage ditch under grafting union; arranging a drainage ditch in the tree at the stock root, engraving a chute above the stem base or cutting the root; manually assisting discharge of retained water. The practical application shows that the method can significantly improve the survival rate of the branch scion top graftingof the juglans sigillata dode, promote early growth and quick tillering of scion buds, improve the robustness of the new scion branches, and is suitable for popularization and application in the south. In addition, the method is simple in operation, rich in industrial paraffin wax and beeswax source, low in cost and easy to implement.

Description

technical field [0001] The invention belongs to the technical field of walnut grafting, and in particular relates to a water control method for high grafting of southern pickled walnut branches and scions. Background technique [0002] After searching, there are many reports on high-level grafting of walnuts, but only a few of them involve water regulation. Examples of relevant patents are as follows: [0003] In the Chinese patent application "Grafting and Breeding Method of Hemp Walnut with High Survival Rate" (patent application number 201410359634.6), the scion is cut off and then sealed in wax for storage. The survival rate can reach 97%. [0004] In the Chinese patent application "a wild pecan grafting technology" (patent application number 201110236874.3), the fracture of the rootstock is cut into a bevel, which is in the shape of a "V". Cover the saw cuts of the rootstock to expose the scion branches, and tie them tightly. This grafting technique is simple in ope...
