Problems solved by technology

The breeding of fine hickory varieties is mainly through grafting. The rootstocks used for grafting and propagation are mainly self-root stock and seedlings cultivated by sowing hickory seeds. Due to the high price of seeds, the cost of seedlings is too high
There are about 100-160 seeds per kilogram of pecan, with a germination rate of 60%, a seedling rate of 95%, and a seedling rate of 52-91 per kilogram of seeds, so the cost price of each seedling is 1 yuan In addition, there are

Embodiment 1

[0032] (1) a kind of method for the breeding of Carya carya seedlings of the present invention, comprises the steps:

[0033] (1) Preparation and processing of cuttings:

[0034] In the first ten days of February every year, select annual thin-shell hickory seedling branches, cut into short branches with a length of 10cm, and soak the lower end in 800mg / L NAA solution for 4h;

[0035] (2) Cutting seedbed preparation:

[0036] Make a 60m×8m greenhouse, cover the outside with a plastic film, and cover the film with a sunshade net, level the ground and make a 20m×2m furrow with a height of 40cm, lay melon seeds flakes of small stones 10cm below, and then spread electric heating wires. Spread an 8cm-thick substrate on the electric heating line, which is a mixture of 40% perlite, 40% peat soil, 15% river sand, and 5% vermiculite;

[0037] (3) Cuttings:

[0038] Put the substrate into a paper bag with a diameter of 6cm and a height of 9cm made of kraft paper. The substrate is flu...

Abstract

The invention discloses a method for propagating apocarya seedlings. The method comprises the steps of selecting an annual apocarya seedling branch, shearing the branch to be the length being 10 cm, and soaking the lower end of the sheared branch into an 800 mg/L NAA solution for 4 h; placing a matrix into a paper bag, inserting a cutting into the matrix, enabling the paper bag obtained by cuttage to tightly abut against a mesh disc with a hole, and placing the paper bag on a seedbed; in the cutting rooting process, keeping the soil humidity to be about 70%, and keeping the temperature of the lower end of the cutting to range from 25 DEG C to 30 DEG C; conducting grafting 40 days after cuttage, adopting the bark peg grafting method, transferring the kraft paper bag, obtained after grafting, with the cutting into a large pot, filling the periphery of the pot with the matrix, pulling out 4/5 of the kraft paper bag, observing the grafting survival rate 15 days after grafting, completely removing the paper bag, and then conducting high-density nutrient and water management. According to the method, the apocarya nursery stock can grow more than 80 cm in the current year, and the survival rate is more than 90%.

Description

technical field [0001] The invention belongs to the technical field of fruit tree and tree cultivation, and relates to a method for breeding hickory carya seedlings. 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, pecan is an excellent economic tre...
