How to grow chestnut seedlings, how to grow chestnuts

There are two main methods of propagation of chestnut: seed sowing and grafting. The first is the selection of chestnut rootstock seeds, the seeds of chestnut rootstock need to be suitable for the local climate and environment to grow, strong resistance to stress, the fruit is two big, and the fruit is harvested after natural ripening. After the seeds are harvested, they need to be stored properly, and they can be stored in sand, tanks, cellars, and trenches.

Nursery plots need to be well drained and disinfected. Seeding can be done in a direct way. Use 60 to 85 kg of seeds per mu, put two large or three seeds in each hole, and then cover about 5 cm of soil and cover with mulch.

When the seeds germinate, the mulch film is pierced in time. When the seeds grow to about 10 cm, top dressing should be carried out in time, each plant should use 2 grams of compound fertilizer, and potassium dihydrogen phosphate solution can be appropriately sprayed as foliar fertilizer when the seedlings grow to 20 cm.

Grafting of chestnut seedlings.

Grafting can be carried out when the rootstock grows to a diameter of more than 1 cm and a plant height of about 80 cm. The scion needs to be selected about 30 days before the grafting work. It needs to be carried out before the chestnut tree germinates, and the annual branches on the high-quality chestnut tree are selected, the length of the cut is about 15 cm, and there need to be two to three full bud points.

Then the selected scion branches are stored in the cellar, which can be buried in wet river sand, and the temperature is controlled at about 3 degrees.

The time of grafting should be determined according to the selection of grafting method and local climate and environment. The grafting method can be cleaved, budded, inserted and ventral grafted. After the grafting work is completed, the management of seedlings should be done.

First, the choice of garden.

Choose gravel and sandy loam soil with deep soil layer, high humus content, loose soil, good air permeability, good drainage, and pH value to plant chestnut. In addition, it is advisable to choose flat land, sunny slope and semi-sunny slope for planting.

Second, the main points of planting.

Flat land and gentle slope land shall be fully reclaimed and land preparation, and slope land with large slope shall be carried out in strip land preparation to avoid soil erosion. In the planting planning of the planting pit, select excellent seedlings, and the planting depth should be equal to the interface of the grafted seedlings and the surface. After the seedlings are planted, fill the squatting pit water, and spray a new high-fat film to protect moisture after sealing the soil.

Anti-evaporative evapotranspiration.

3. Management of chestnut orchards.

In summer and autumn, hoe and loosen the soil once, which not only eliminates the surrounding weeds, but also improves the soil structure, which is conducive to the growth and development of the root system. It is necessary to irrigate and fertilize in a timely manner according to the growth needs to ensure the nutritional requirements. It is necessary to strengthen the comprehensive prevention and control of pests and diseases, focusing on prevention and combining prevention and control.

After the garden is completed, it is necessary to paint and promote Kao No. 2 during the flower bud differentiation period every year to promote flower bud differentiation, inhibit the wild growth of shoots, promote flowering, keep fruit set, and balance the size of the year. Before chestnut flowering, young fruit stage and fruit expansion stage, it was sprayed to effectively thicken the fruit pedicle and speed up the fruit swelling speed.

5. Clear the garden and protect the trees.

When clearing the orchard, the dead branches and fallen leaves, diseased residual branches, and fallen dead fruits scattered in the orchard will be treated in a centralized manner. During winter pruning, prune strong branches, diseased and insect branches, overlapping branches, and competitive branches, and lightly prune the extension head of the main branch. The wound during pruning is sealed with a "callus antiseptic film" to promote wound healing and reduce pests and diseases.

It is necessary to smear the tree body with "Tree Protector General" to protect the flower buds from frost damage during the winter.
