High stumped grafting method of vine

Abstract

The invention discloses a method for grape top grafting for varietal change. The procedures are as follows: the first step is to choose an appropriate grafting time; the second step is cladus and bud cutting; the third step is the choice of grafting position and the opening of the top grafting position; the fourth step is the side grafting and the enswathement of scion bud; the fifth step is the appearance of scion bud and new colligation; the sixth step is the tending such as post pruning, bud feeling, lead binding, fertilizer water, and extermination of disease and insect pest. The simple and flexible method of the invention has convenient manipulation, simple post management, high scion bud survival rate (more than 90 percent), high sprouting and flowering rate of the germinating scion bud in current year (up to 50 percent), early germination of the scion bud, healthy and strong branches and tendrils, quick forming, low cost, early fruit bearing and high economic benefit, thereby easy for producers to accept and convenient to popularize and apply.

Description

technical field [0001] The invention relates to the field of grafting of horticultural fruit trees, and more specifically relates to a method for high-grain grafting and replanting of grapes. Background technique [0002] The output and area of ​​grapes in the world's fruit production have always been in the forefront. It has strong adaptability, early results, high yield, rich nutrition, wide range of uses, and high economic value (Hebei Agricultural University, editor-in-chief, "Monographs of Pomology", Agricultural Press, 1984: 101-152). With the breeding and introduction of new and excellent varieties, the varieties cultivated in production also need to be continuously updated. There are two main methods for updating grape varieties: one is to re-establish the garden, and the other is to replant and replant. The former method takes effect slowly and costs a lot, and after digging and rebuilding old orchards, pests and diseases increase due to heavy cropping, and yield a...

Problems solved by technology

[0005] In order to achieve the above purpose, in view of the problems existing in the conventional high-grafting technology of grapes, which are prone to injury in spring grafting and the survival rate is low, the growth of grafted shoots in summer is weak, and the management is difficult, etc., innovations have been made.
