How do you select pecan seeds? What are the propagation methods?

Pecan is the fruit of the American hickory, also known as thin-shell hickory or long hickory, and is one of the world's top ten nuts, also known as thin-shell hickory, "longevity nut", "American hickory", "long hickory". Pecans are rich in fats, sugars, protein, multiple vitamins and minerals, and have the effects of tonifying the kidneys and strengthening the brain, supplementing the middle and boosting qi, moisturizing the skin, and darkening the hair and beard. So how do you select pecan seeds? What are the propagation methods? Let's take a look together below.

1. How do you select pecan seeds?

Many farmers directly choose to buy pecan saplings on the market, but in fact you can raise the seedlings yourself. Growers select plump and healthy seeds, choose a suitable growing environment, and then cultivate pecan saplings.

Pecan seeds must be stored well. If the seeds lose water, it easily reduces the pecan seedling emergence rate. You can also first subject the pecan seeds to sand storage treatment, which can increase the pecan seedling emergence rate.

2. What are the propagation methods for pecan?

1. Seed propagation

After the fruit is harvested, spread it in a well-ventilated indoor place. After most of the outer fruit skins have split, take out the seeds. Sowing can be done in both spring and autumn, but autumn sowing is not as safe as spring sowing, because the seeds are easily gnawed by rats and birds, and sometimes in winter drought the seeds lose water and the seedling emergence rate is low. Autumn sowing is usually completed before the soil freezes in autumn, while spring sowing should be early and can be done in mid-March. If sowing in spring, the seeds must undergo sand storage treatment.

2. Grafting propagation

The rootstock used for grafting is generally hickory; in the cold regions of North China, Manchurian walnut is used; in the Yangtze River basin, wild hickory is mostly used; in Shandong and Shaanxi, Chinese wingnut is used. Collect scions from superior individual plants, and select fully developed branches from the outer canopy that are sturdy, 30-40 cm long and 1-1.5 cm thick. Use the plump, full buds in the middle and lower parts of the scion as graft buds.

3. Cutting propagation

Pecan cutting propagation usually uses sturdy 1-year-old branches, with cuttings 17-20 cm long. With ordinary cutting methods, the survival rate is over 90%.

4. Root cutting propagation

Collect roots in conjunction with nursery stock being lifted from the nursery, then heel them in, and carry out cutting in spring. The root pieces are 1 cm in diameter and 10 cm long, and bed planting is preferable. The upper cut end of the root must be buried 0.5-1 cm below the bed surface.

5. Layering propagation

During the dormant period, press sturdy branches from the base of the mother plant into the soil. After a period of time they can root, then separate the branches from the mother plant and transplant them for further cultivation.

The above is an introduction to pecan. The pecan shell is very thin and can be peeled open by hand. The taste of the kernel falls between the hickory and walnut we commonly eat, and its rich, crisp texture is mouthwatering. Pecan is a dried fruit with an oblong shape. It originated in the United States on the North American continent and northern Mexico, and has now become one of the world's dried fruit tree species, with broad planting prospects.
