Problems solved by technology

Although the grafting technology of thin-shell hickory nuts was fully mature in the year of sowing, the seedlings formed by grafting were very weak, known as "rat tails", and it took another year to grow out of the nursery in the second year, and the quality of the seedlings formed was relatively poor. It can be seen that it takes at least 2 years, or even 3 years, to propagate high-quality hickory seedlings
Because the cost of land is relatively expensive, plus the cost of seeds and labor costs, the cost of raising seedlings is expensive
At present, the market demand for thin-shell hickory seedlings is very large, and the current seedlings can no longer meet the needs of the market

Embodiment 1

[0026] (1) a kind of method for the rapid propagation of hickory nut fine variety seedling, comprises the steps:

[0027] 1) Pregermination: select full-bodied seeds, remove impurities and classify, soak the seeds for 24 hours after insecticide and sterilization treatment, dry the surface water after soaking, and then perform stratification treatment. High-temperature germination is carried out in plastic greenhouses on February 5 every year.

[0028] 2) Grafting, on March 25 every year, pick up the sprouts together with the seeds, use a scalpel to quickly cut off the upper part about 4cm away from the seeds, and cut the middle of the cut down about 1.5cm long as the rootstock; select Extended branch of fine hickory variety with 2‐3 buds, about 6‐8cm long, cut into a thin wedge, and then inserted into the cut of the rootstock, with one side aligned with the edge of the rootstock, glued with medical paper tape Tighten the roots of the sprouts and physically cut the roots to a l...

Abstract

The invention discloses a method for rapidly propagating apocarya good variety seedlings. The method comprises the steps of (1) germination acceleration; (2) grafting, wherein a scalpel is utilized for cutting off the upper portion of the position, 4cm away from seedling grains, of the bud seedlings, the cut is cut open downwards from the middle, a branch of an apocarya good variety is selected, cut into a thin wedge shape, and inserted into the kerf of the stock, one side of the branch is flush with the edge of the stock, a piece of medical paper adhesive tape is used for tight adhesion, and after being physically and completely cured, the bud seedlings are transplanted into a black polypropylene plastic nutrition bowl; (3) management after grafting. Compared with other methods for cultivating the apocarya seedlings, the method has the advantages that more than 90% of cultivated seedlings in the current year are strong, the strong seedling cultivation time is shortened by one to two years, the cost is saved, and the method has the great significance in strong seedling rapid cultivation of apocarya.

Description

technical field [0001] The invention belongs to the technical field of fruit tree and tree cultivation, and relates to a method for rapid propagation of seedlings of fine varieties of hickory nuts. Background technique [0002] Thin-shelled hickory, 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 timber tree species for construction and high-end furniture. Therefore, pe...
