Embodiment 1

[0030] Embodiment 1: a kind of method for cultivating grafted seedlings of the original stock grafted in the year of grafting in the year of sowing of a kind of thin shell pecan, the steps are as follows:

[0031] (1) The establishment, sowing, and seedling raising of the original stock nursery of Carya carya, adopt the improved open-field sowing method to cultivate the seedlings of the year, and carry out the root cutting process when the seedlings and seeds are transplanted from the seedbed to the nursery;

[0032] (2) The establishment of the ear-picking nursery is to cultivate the female parent tree of ear-picking with the growth branch of the adult tree of Carya carya as a scion;

[0033] (3) choose the hickory carya seedlings with ground diameter ≥ 0.5cm and strong growth in the year sowing seedlings as rootstock, and carry out cut-off treatment on the above-ground 25cm part of rootstock one week before grafting;

[0034] (4) For the collection and storage of scions, in ...

Abstract

The invention discloses a new technique for culturing apocarya by seeding and grafting in the current year. The technique comprises the following steps: culturing the apocarya in an improved outdoor sowing method for seedling in the current year; cutting the root when seedlings and seeds are transplanted from a seedbed to a nursery, and building a free stock nursery; selecting the robust apocarya seedlings in current year as the free stock which has leading thread more than or equal to 0.5cm from the seedlings sown in the current year; cutting the part of the free stock on the ground above 25cm in a week before grafting; choosing branches grown in the current year having full bud, short inter-node and rich development from a grain ear picking tree, and carrying out patch budding on the branch on the part of the free stock about 10-15cm on the ground in the solar terms having average daily temperature from 25 to 30 DEG C between August and September; and before wrapping up, tearing down a small phloem from the part under the free stock notch so as to ensure that the bleeding can flow out. By utilizing the technical scheme, the apocarya which is sown in the current year can grow into a tree having the thickness meeting the demand of grafting; and through grafting in the current year, the seedling period is shortened, the tree is dwarf, the juvenile phase is shortened, and the fructification is obtained earlier.

Description

technical field [0001] The invention belongs to the technical field of plant seedling cultivation, and in particular relates to a new technology of seedling cultivation which is sown in the same year and grafted in the same year. Background technique [0002] Thin shell hickory [Carya illinoensis (Wangenh.) k. Koch.], also known as American hickory, is a species of Juglandaceae and Hickory. Native to the United States and Mexico, it is one of the most important oil-bearing dried fruit tree species in the world. Its shell is thin and easy to peel, its kernels are thick and fleshy, and it has a delicious taste and high nutritional value. The trunk is straight, the tree shape is beautiful, the roots are deep and the leaves are luxuriant, and it is an excellent tree species for greening and gardening around. At the same time, the wood is tough and dense, with dark red heartwood, yellow-white sapwood, high elasticity, and is not easy to deform and crack. It is an excellent timbe...
