Inversed bud grafting method of grape trees

Abstract

The invention discloses an inversed bud grafting method of grape trees. The inversed bud grafting method of the grape trees comprises the steps that 4-10-year-old seeding grape trees with good growingconditions, well-developed root systems, no diseases and insect pests, and roughness of diameter at breast height being 3.0 cm or more are selected as rootstocks; adult grape plants with robust growth and no quarantine diseases and insect pests are selected as scion mother trees; a smooth and flat position of rootstock bark is cut horizontally and vertically with a knife to form a T-shaped cutterpoint; the position 2-3 mm below a bud is transversely cut with a knife, then a knife cuts into the position 1.5-2.0 cm above the bud and is pushed upwards to cut to a traverse cutter point under thebud, a bud piece is taken off, a notch cortex of a rootstock is pried, the cut inversed bud woody bud piece is gently inserted into the T-shaped cutter point and wrapped tightly with a plastic stripof 2-3 cm wide, and the buds and petioles are left outside; after bud grafting, a rain and shade shelter is set up to block rain and direct sunlight, and the rain and shade shelter is removed gradually after germination; after the grafting survives for about 15 days, rootstocks above grafting points are cut off; and after grafting survival, pruning management can be strengthened in the second year, namely, management in accordance with conventional grape management methods can be carried out.

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
