Bud grafting method of walnut top grafting optimization

A walnut and high-grafting technology, which is applied in the field of early-fruited walnut high-grafting to high-quality budding, which can solve the problem of being vulnerable to wind breakage, unstable survival rate of high-grafting grafts, and affecting the survival rate and preservation rate of high-graining and high-quality walnut low-yield gardens. To achieve robust growth, prevent low-temperature freezing damage, and facilitate rapid growth

Embodiment 1

[0037] A bud grafting method for high grafting of early fruit walnuts to high quality, mainly comprising the following methods:

[0038] (1) Rootstock treatment: Use early-fruited walnut seedlings to build gardens, and they can bear fruit in the third year after planting. If the walnuts still do not bear fruit or the results are inconsistent after 3 to 6 years after planting, it is judged that the tree is not a good-bred walnut grafted seedling. , It is necessary to implement the improvement of high-speed connection, and the observation can be carried out in the first year, and it will be listed and marked, so as to prepare for the improvement of high-speed connection in the next year.

[0039] (2) Scion collection: In the morning or after 4 o'clock in the afternoon, collect the developed branches of the early-fruiting walnut excellent new variety 'Xiangling' that are robust, full of leaf buds, mature buds, and free from diseases and insect pests in the same year as scions. Af...

Abstract

The invention discloses a bud grafting method of early-fruit-bearing walnut top grafting optimization. The bud grafting method mainly comprises the steps of selection and treatment of stocks, acquisition of scions, selection of grafting time, grafting treatment and management after grafting; the bud grafting method is characterized in that in selection and treatment of the stocks, early-fruiting-bearing walnut good variety grafting saplings are utilized to build a garden, fruit bearing can be achieved in the third year after field planting, if walnuts still do not bear fruits 3-6 years after field planting or borne fruit are not uniform, it is judged that the trees are not the good variety walnut grafting saplings, top grafting optimization needs to be conducted, observation can be conducted in the first year, and boards are hung for marking to conduct top grafting optimization in the next year; the selected stocks are perennial branches, and the branch thickness is 2.0 cm-8.0 cm; thegrafting portions of the scions are the perennial branches, nutrients are centralizedly supplied and not easily diffused, the fast growth of the scions is promoted, the grafting variety branches are robust and vigorous in growth, and the occurrence of winter low-temperature frozen injuries is prevented.

Description

technical field [0001] The invention belongs to the technical field of high-efficiency cultivation of fruit trees, in particular to a bud grafting method for high-grained early-fruited walnuts. Background technique [0002] At present, the walnut cultivation area in my country is growing rapidly. In the actual production, due to the uneven varieties of good and bad varieties in the walnut orchards that have been planted, the growth of the orchards is inconsistent, the individual differences are large, the results are few or the fruiting period is late, which seriously affects the economic benefits of the growers. The walnut plantation is improved. The level needs to be further improved, and the existing low-yield walnut orchards urgently need to be transformed by grafting improved varieties to obtain higher economic benefits as soon as possible. High grafting to high-quality is one of the commonly used technologies for orchard transformation at present. It can quickly realize...
