Grape hard branch grafting method

Abstract

The invention relates to the technical field of grafting, in particular to a grape hard branch grafting method. The hard branch grafting method comprises the steps of carrying out hard branch graftingbetween the end of March and the beginning of April, inserting a scion into a stock, and at least aligning one side forming layer; inserting a grafted branch into wax juice with the temperature of 76-80 DEG C for dipping wax, and then cooling; dipping a stock base part in a rooting agent, placing the stock base part in a substrate, and carrying out shading storage for 30-40 days under the conditions that the temperature is 20-25 DEG C and the relative air humidity is 70%-80%; and when root primordia and radicles appear in the stock base part, hardening and transplanting grafted seedlings. After the wax dipping temperature is adjusted to 76-80 DEG C, the problem that a grafting opening is burnt to death due to the fact that the temperature of the grafting opening is too high, and the survival rate is affected is solved.

Description

technical field [0001] The invention relates to the technical field of grafting, in particular to a method for hard branch grafting of grapes. Background technique [0002] Grape seedling raising technology is one of the key links for high-yield and high-quality cultivation of grapes, which directly affects the growth rate, growth and yield per unit area of ​​the tree. At present, the most important method of grape seedling cultivation is hard branch cutting seedling cultivation. The branches are inserted and cut now, and the survival rate is high. If there is a large amount of seedlings, they can also be pruned indoors in winter, and then buried with moist river sand or sandy loam to reduce water loss. In the first ten days of April, take out the cuttings stored in the previous year and cut them into strips. The cuttings are placed neatly on the hotbed, and the pores between the cuttings are filled with fine sand and watered thoroughly. After the whole hotbed is filled wi...

AI Technical Summary

Problems solved by technology

[0004] The operation of cutting seedlings is relatively simple, the reproduction coefficient is high, and the cost is relatively low. It can maintain the excellent characteristics of the original variety. However, the cutting seedlings of grapes will lead to poor resistance of the seedlings, which cannot resist root-knot nematodes, phylloxera and other hazards. Especially in the large area of ​​our country, the soil conditions in each area are different, and cutting seedlings cannot better adapt to different harsh environments

The survival rate of green branch grafting is relatively high, but the breeding cycle is long

At present, there are still many problems in grape grafting, such as poor joint healing, poor rootstock quality, unsuitable environmental conditions, chaotic varieties, unreasonable transplanting process and other technical problems, resulting in poor survival rate of grafted seedlings and untransplanted plants. The phenomenon of death when or after transplanting
