What to do if the walnut tree sprouts after it is cultivated

The phenomenon that walnut trees do not germinate, or sprout back to bud, is generally related to the poor growth of walnut tree roots, or rotten roots. If the buds are dry, or the sprouts do not like to grow, it may be because the soil is not suitable. Walnut trees are light-loving, drought-resistant, waterlogging and wet, and are suitable for places with loose soil and smooth drainage.

If the soil moisture is too high, the roots will not breathe well and will be susceptible to spoilage.

In general, organic fertilizer is the main fertilizer, especially in August and October, the soil moisture is better, the root system is active, and the fertilization is still relatively good at this time. It is recommended to adjust the amount of fertilizer according to the size of the tree and the amount of fruit. Soil with good fertilizer is about 100 grams of urea, 30 grams of superphosphate, and about 10 grams of potassium nitrate can be applied to each plant.

Fertilization method: Ring fertilization of roots, foliar fertilizer can also be sprayed, foliar fertilizer spray about 5% urea, potassium chloride.

What should I do if it sprouts and sprouts back?

Freshly planted trees sprout and sprout back, which is dangerous. Because the germination of trees needs nutrients, and the roots of the newly planted trees are damaged and can not absorb nutrients well, so the germination part can only absorb the nutrients of the trunk itself, and after the trunk nutrients are absorbed, the roots can not supply the trunk nutrients in time, and the phenomenon of budding back is produced.

Solution: During or after planting trees, irrigate the roots with the rooting solution of the happy forest, and inject the activation solution into the tree body with the trunk of the happy forest, so as to adjust and provide nutrients to the tree body in the shortest time and at the fastest speed, so as to improve the survival rate.

Summary. Hello, dear. The germination of walnut trees in winter should be serious with the autumn rain and walnut leaf black spot disease, resulting in early leaf loss and the secondary growth phenomenon of high temperature.

New shoots mostly occur in the upper part of the canopy and at the top of the branches, and these young shoots can be thinned out during winter pruning. If there is not much secondary flowering, it will not have much impact on next year's yield. However, early defoliation will reduce the amount of nutrients stored in the plant, so fertilizer and water management should be strengthened in the following spring to reduce the impact on yield.

Kiss, hello pin chain. The germination of walnut trees in winter should be serious with the autumn rain and walnut leaf black spot disease, resulting in early leaf fall and the temperature is still high.

If there is not much secondary flowering, it will not have much impact on next year's yield. However, early defoliation will reduce the amount of nutrients stored in the plant, so fertilizer and water management should be strengthened in the following spring to reduce the impact on yield.

Secondary germination. Hello, dear. When the second germination and pruning are pruning, you can cut off the new sprouts.

1.The interface is not well handled, and the nutrients needed for the germination of scion long branches cannot be provided by the rootstock. 2.

There is a problem with the selection of rootstocks, and the spine may be of different classes of the same family, or different species of the same kind, resulting in dryness, 3The rootstock itself is not enough to provide nutrients to the scion.

If you want to plant walnuts with high germination rate and fast germination, you should start from collecting seeds, choose the seeds on the walnut tree with full grains, dry them for 3 5 days after hulling, choose your own convenient storage method, bury the sand in mid-March to promote germination, and transplant after the shell cracks to expose the white buds.

Walnuts generally ripen in August and September, and the seeds used for sowing should be collected on walnut trees that bear fruit early, have high yields and stable yields, and are adaptable. Walnut sowing can be carried out in spring and autumn, and if it is an autumn sowing walnut, it does not need to be stored; If sowing in spring, store the seeds for germination.

Walnut fruits sown in spring, after collecting the seeds, take off the green skin on the outside; Then turn and dry in the sun for 4 to 5 days, until the peel on the outside of the walnut kernel becomes golden brown and it is not easy to separate from the walnut kernel, and the dried walnut kernel is stored.

There are three ways to store walnut seeds, method 1: directly put the dried walnut kernels in a cloth bag and hang them in a cool, ventilated, dry and backlit place indoors; Method 2: Mix walnut kernels with moist sand and store them together; Method 3:

Placed directly in the cold storage of 0 1.

Before walnut planting, germination begins, first soak the seeds in cold water for 2 3 days; Then put it in a 30 35 cm high wet sand pile, covered with 10 cm of wet sand, insist on watering every day, cover it with film at night to help keep it warm, 10 15 days the shell will crack, leak out the white buds inside can be planted.

After the walnuts germinate, they are directly selected for planting, and can be grafted from late March to early April of the following year. When walnut buds germinate in mid-March, annual and robust shoots are selected as cuttings, collected and stored in wet sand, and grafted in early April.

The rootstock used for grafting walnuts is generally about centimeters thick and grafted at a distance of 10 cm from the ground. Before grafting, scratch the rhizosphere of the rootstock, deep enough to see the xylem inside, split or plug the branch within 12 hours, and then tie the wound tightly with plastic film, in order to prevent water evaporation, it can be painted on the upper end of the scion.

After the grafting is lived, when the new one grows to 20 cm long, the plastic film can be loosened, and the new sprouts can be removed in time, so that the nutrients can be concentrated in the new one. When the grafted seedlings grow to about 40 cm, they can be fixed with supports to prevent the new branches from being blown by the wind.
