Navel orange grafting method

Abstract

The invention discloses a navel orange grafting method. The method comprises the steps as follows: 1) rootstock and scion selection, wherein a navel orange sapling of 4 to 5 years old is selected as a naval orange rootstock, and a fruit-bearing blood orange branch is selected as a scion; 2) grafting method, wherein selection of 20-25 secondary branches for grafting is appropriate, others are cut off, the number of grafted buds is 40 to 50, grating ought to be performed in October after fruits of first-year quinces are picked, excellent aged and vigorous navel orange autumn shoots are selected, and grafting is completed with a bud whole-packaging method; 3) binding; 4) grafting management after grafting plant, wherein from the second year after fruit bearing, renewal of fruiting branches is performed. The navel orange grafting method has the advantages that renewal of fruiting branches is performed through blood orange branch and naval orange grafting, so that the illness rate of naval orange trees is low, the fruit bearing age is long, and the good fruit rate is high.

Description

technical field [0001] The invention belongs to the technical field of cultivation of hops, grapes, fruit trees or similar trees, in particular to a navel orange grafting method. Background technique [0002] Most of the existing navel orange cultivation methods are open-field planting, and after open-field planting, the ripening period is roughly in the middle and late May. For example, the Tao Jizao 518 variety matured on May 18. After that, various varieties of peaches have been concentrated on the market. , because its planting technology is simple and its management is extensive, so the benefits are average, and fruit tree growers cannot sell at a good price. After the popularization of greenhouse fruit tree cultivation technology in the north, the time to market peaches is only about one month earlier than the original basis (April); In addition, the grafting of existing navel oranges generally adopts branches and peach trees of other species with similar habits to gra...

After the popularization of greenhouse fruit tree cultivation technology in the north, the time to market peaches is only about one month earlier than the original basis (April); In addition, the grafting of existing navel oranges generally adopts branches and peach trees of other species with similar habits to graft, and the branches that are grafted out like this are not particularly strong in growth; short growing years
