Method for grafting grapevine

Abstract

The invention provides a method for grafting a grapevine, and relates to the technical field of fruit tree cultivation. According to the method, when seedling-raising by grafting is conducted, selection of a grapevine rootstock is the first issue to be taken into consideration, different rootstocks have different adaptations and requirements on the environment, are different in rooting situations and scion variety grafting compatibility situations, and especially have different resistances to soil-borne diseases and pests, such as phylloxera, nematodes and agrobacterium tumefactions, so that the variety of a grapevine rootstock suitable for the local area or a local wild grapevine is selected as the rootstock by comprehensively taking the soil, climate and local diseases and pests in the grape development area, the market required grapevines and other factors into consideration before seedling cultivation; grafting is conducted by adopting a grafting and cuttage propagation method or rooted nursery stock grafting method; and after-grafting management should be taken into consideration. The method is simple, is convenient for practical operation, has a high survival rate, is convenient to manage, and can be used for effectively improving the disease resistance of grapevines and increasing yield.

Description

technical field [0001] The invention relates to the technical field of fruit tree cultivation, in particular to a grape tree grafting method. 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 capillary root is getting fart...

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 to the soil. The decline in nutrient capacity is getting bigger and bigger, so that its grape production declines year by year; (2) This cultivation method makes the tree body of the vine grow year by year, and the tree body is more than two meters long in the fifth year after planting. 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
