Embodiment 1

[0039] A method for grafting and tree body shaping of perennial walnut trees , as follows:

[0040] (1) Grafting method

[0041] ① Select a 6-year-old walnut tree with a trunk height of 80cm. Combined with grafting, all branches below 80cm are cut off. The grafting parts are the central trunk and main branch. The grafting thickness of the main branch should be > 2.0cm, and the thickness < 2.0cm All the main branches are cut off, and there are 5 joints per tree, and the grafting time is from the budding to the leaf-expanding stage.

[0042] ②Trunk wounding and draining: on the trunk 20cm from the ground, use a saw to wound horizontally, reaching the xylem, and then wound on the other side of the trunk. The vertical distance between the two wounds is 20cm.

[0043]③ Rootstock treatment: keep the main branch 10cm, saw off the main branch at the smooth part of the main branch, use a grafting knife to peel off the sawdust on the saw surface, flatten the saw edge, and make a verti...

Embodiment 2

[0054] A method for grafting and tree body shaping of perennial walnut trees , as follows:

[0055] (1) Grafting method

[0056] ① Choose a 7-year-old walnut tree with a trunk height of 80cm. Combined with grafting, all branches below 80cm are cut off. The grafting parts are the central trunk and main branch. The grafting thickness of the main branch should be > 2.0cm, and the thickness < 2.0cm All the main branches are cut off, and there are 4 joints in one tree, and the grafting time is from after budding to the stage of leaf expansion.

[0057] ②Trunk wounding and draining: on the trunk 20cm from the ground, use a saw to wound horizontally, reaching the xylem, and then wound on the other side of the trunk. The vertical distance between the two wounds is 20cm.

[0058] ③ Rootstock treatment: keep the main branch at 15cm, saw off the main branch at the smooth part, use a grafting knife to peel off the sawdust on the saw surface, flatten the saw edge, make a vertical cut fro...

Abstract

The invention relates to a method for grafting and shaping tree bodies of perennial seedling walnut trees. The method comprises following steps of: (1) selecting seedling walnut trees at tree age of more than 5 years as stocks, adopting an improved bark grafting mode in such a manner that scions are connected to stocks, dewatering outlets are arranged right under vertical knife edges of the stocks to the depth of xylem parts, diversion pipes are inserted to the dewatering outlets, scions and stocks are sealed and bound, the dewatering outlets and the diversion pipes are sealed and bound; and (2) shaping after grating. The method for grafting and shaping tree bodies of walnut trees has following beneficial effects: prior to grating, water is drained off on main trunks in order to reduce impact of root pressure upon upper main brunches on the ground in order to be favorable to graft union; grating survival rate is increased; the diversion pipes are inserted in directions facing the stocks of scions so that water is completely drained off; technology of the diversion pipes is adopted in order to reduce breeding influence during grating and comprehensively increase survival rate of walnut grating; and seedling walnut trees can be produced prematurely and stably in high yield.

Description

technical field [0001] The invention relates to a seed tree improvement method of fruit trees, in particular to a method for grafting and tree body shaping of perennial seed walnut trees. Background technique [0002] Walnut is an important woody grain and oil strategic tree species in my country. It has high economic, ecological and social benefits and strong adaptability. It is an important source of income for farmers in hilly and mountainous areas. As a major walnut-producing province, Shandong Province has attached great importance to the development of the walnut industry over the years. The Shandong Provincial Fruit Industry Revitalization 'Twelfth Five-Year' Development Plan (2011-2015) also pointed out that walnuts and chestnuts are the two major dried fruits. Create a group of standardized parks with high quality, good benefits, and strong demonstration and driving capabilities, and focus on building 100 provincial-level standardized demonstration parks with an are...
