Root grafting method for navel oranges

Abstract

The invention relates to a root grafting method for navel oranges. The method comprises the following steps: A, collecting a branch having tender shoots of a Fengjie navel orange tree, so as to obtaina scion; and collecting a root part having a diameter of 1-5 cm and a length of 10-20 cm of the navel orange tree, so as to obtain a rootstock; B, grafting the scion to one end, far away from root hairs, of the rootstock, and performing seal binding on a connection position of the scion and the rootstock, so as to obtain a grafted seedling; C, soaking the grafted seedling by using water, plantingthe soaked seedling into a culture substrate, performing cultivation, and in the cultivation process, watering the grafted seedling; and D, when the bound position of the grafted seedling is germinated, continuing cultivation after the bound position is opened, and when new shoots are exposed to the exterior of the bound position of the grafted seedling, performing seal binding again, and continuing cultivation, so as to obtain the grafted navel orange fruit seedlings. The method provided by the invention is simple and easy to operate, saves manpower, the fruit tree has a high cultivation survival rate and rapid growth, fruit bearing is 2-3 years earlier than that of a method of raising seedling on seeds and then performing grafting, and the harvested navel oranges have a more excellent variety and a more abundant yield.

Description

technical field [0001] The invention relates to the field of navel orange planting, in particular to a navel orange grafting method.

Problems solved by technology

Due to the small size of navel orange seedlings, after planting in the mountains, and the poor management of fertilizer and water, many seedlings only survived and did not grow trees, and some of them became "little old trees" prematurely, which seriously affected the development of navel orange industry.
