Inverted-bud grafting method for vines

Abstract

The invention relates to an inverted-bud grafting method for vines. The method comprises choosing a 4-10-year seeding vine which is good in growing conditions, prosperous in root, has no plant diseases and insect pests, and has a diameter at breast height being more than 3.0 cm as a stock; choosing a prosperous grown vine without plant diseases and insect pests as a seed tree to be cut; transversally and longitudinally cutting a smooth and flat portion in of the stock to using a knife to form a T-shaped cut; transversally cutting under a bud 2 to 3 mm, cutting inwards and upwards at the position higher than the bud 1.5 to 2.0 cm until reach the transversal cut under the bud, taking the bud out, levering the cortex at the cut of the stock, slightly inserting the cut inverted wood bud into the T-shaped cut, tightly wrapping the cut using a plastic strip whose width is 2 to 3 cm and making the bud and a petiole at the outside; establishing a shelter for shading rain and direct sunlight after bud grafting, and gradually removing the shelter after bud; cutting stock over the cut after 15 days from grafting is successful; carefully trimming and managing in the next year after the grafting is successful, and then managing according to a conventional vine management method.

Description

technical field [0001] The invention relates to the technical field of fruit tree cultivation, in particular to a method for grafting inverted buds of grape trees. Background technique [0002] At present, the known vine cultivation method is to plant the vines, pruning the vines after the autumn of the year when the vines are planted, and leave three to eight strong bud eyes at the base, and then pruning the trunk and branches every year. Leave three to eight sprout eyes. This cultivation method needs to maintain the high-yield period by cultivating the auxiliary branches of the vine from the fifth to the tenth year after planting. However, after 15 years after planting, the vine must be eliminated due to the low yield and then replanted with new vines. This is mainly because (1) this cultivation method makes the vines rely on the root system cultivated during planting for a long time. After ten years of planting, the main root in the root system has aged, and the capillar...

Problems solved by technology

This is mainly because (1) this cultivation method makes the vines rely on the root system cultivated during planting for a long time. After ten years of planting, the main root in the root system has aged, and the capillary root is getting farther and farther away from the soil root, causing the root system to absorb and transport the root system in the soil. The decline of nutrient capacity is getting bigger and bigger, so that its grape yield declines year by year; (2) the cultivation method makes the tree body of grape vine grow year by year, and the tree body is just up to more than two meters in the fifth year of planting, in order to provide its climbing This will not only cause difficulties in planting management, but also reduce the ability of the tree to transport nutrients to the top of the vine due to the excessive growth and aging of the tree, resulting in a decline in its yield

Therefore, this cultivation method mainly has the inability to increase the density of aboveground plants and update the underground root system, it is difficult to control the plant length and fruit setting position, the planting management is difficult, and the soil where the root system is located cannot be improved, which will easily cause the quality of the grapes to decline and cannot be maintained for a long time. Disadvantages such as maintaining full fruit period and keeping plants from aging
