What season is the right time to plant walnuts? What season is a walnut tree planted?

It's definitely autumn. Because the soil fertility is better in autumn, planting walnuts at this time can improve the survival rate of walnut trees.

Spring and autumn are good seasons for planting walnut seedlings, especially bud seedlings, must be planted in spring, spring planting time should be after the soil thaws to before germination, generally from late March to late April.

It is better to plant in the spring in March and April, when the temperature is suitable and is very suitable for the growth of walnuts. Nitrogen and potassium fertilizers should be applied regularly during planting to promote the growth of plant rhizomes.

In mid-March, the seeds were soaked in cold water for 2 to 3 days, mixed with wet sand after being removed, and piled in a sunny place. 30 35cm high, covered with l0cm thick wet sand, sprinkled with water once a day to keep it moist, cover with grass curtain or film moisturizing and insulating at night, 10 15 days when the husk is cracked and exposed to white, you can sow seeds. Pick 1 time a day, sow seeds in batches, and sow seeds with sufficient moisture when sowing.

The rootstock is required to be about 1 5cm thick, and grafted at l0cm from the ground. X0D X0A walnut grafting has a wound flow, not easy to survive, 12 hours before grafting must be carved in the rhizosphere to the xylem "water", and then split or plug the skin, after the wound is tied with a plastic strip, the upper end of the scion is painted with paint to prevent water evaporation. After surviving, remove the sprout and loosen the tie in time, and the untying time should be carried out when the new growth is more than 20cm.

Do not prune after falling leaves, otherwise it is easy to cause damage and affect the growth of the tree. X0D X0A planting time deciduous fruit trees are generally suitable in winter, and evergreen fruit trees are suitable in spring. When planting, the grafting interface should be exposed to the ground, the root system should be extended, and then the soil should be cultivated, steadfast, irrigated, and then sealed after water infiltration, so as to facilitate water retention.

Dispersed trees are tall and walnut trees have a long lifespan, and the hundred-year-old trees can still maintain high yields. The tree is tall, thick and leafy, and the crown diameter of a large walnut tree can reach more than 10 meters, covering an area of 100 200 square meters.

Walnut planting time.

The suitable planting time for walnuts is generally spring and autumn every year. Spring planting starts in mid-March, and autumn generally starts after October. During these two periods, the climate is suitable, and the survival rate after planting is high.

Walnut origin. Walnuts are mainly found in Central Asia, West Asia, South Asia, and Europe. It is commonly cultivated in plain and hilly areas of China. Its main producing areas are North China, Northwest China, Southwest China, South China and East China, as well as the south and west of Xinjiang.

Walnut cultivation method.

Before planting, walnut seeds need to be soaked in cold water for two or three days, fished out, mixed with wet sand, and placed in a sunny place. Sprinkle water every day to keep it moist and cover it with film at night to keep it warm. When the shell cracked socks smile and reveal white, you can sedan and sow seeds, sprinkle them on the soil, and compact and moisturize them after covering the soil.

Key points of walnut planting management.

Proper hearting: walnut new shoots enter the vigorous growth period, and the nutrient branches that do not bear fruit should be topped in a timely manner. When the vegetative branches grow to 6-7 leaves, they need to be pitted, which can slow down the growth dominance and increase the number of branches.

Water and fertilizer management: Early May to early June is the rapid growth period of walnut fruits, and fertilizer is most needed. At this time, water-soluble fast-acting fertilizer should be the main top dressing, and water is also needed during the growth period, and watering is also required after fertilization.

Manual weeding: Summer is the period when weeds are growing vigorously, and manual weeding should be carried out appropriately at this time. In addition, when the weeds grow to a height of 30 cm between the rows, rotary tillage should be carried out once, and mechanical weeding can be carried out 1-2 times in June and July according to the growth height of the weeds.

Walnut seeds can be sown in spring and autumn.

Sowing period: warm in the south is suitable for autumn sowing, cold in the north is suitable for spring sowing. Autumn sowing is generally carried out from mid-October to late November, before the soil freezes.

It should be noted that autumn sowing should not be done too early or too late. In some places, autumn sowing is sown directly with green bark after harvesting. The advantage of autumn sowing is that there is no need for seed treatment, the seedlings emerge neatly in spring, and the seedlings grow robustly.

Spring sowing is generally carried out from late March to early April after the soil has thawed. The disadvantages of spring sowing are that the sowing period is short, the field operation is urgent, and the climate is dry, it is not easy to maintain soil moisture, the seedling growth period is short, and the growth amount is small.

Seed treatment: Autumn seeds do not require any treatment and can be sown directly. When sowing seeds in spring, they are soaked to ensure germination.

Cold water soaking method: soak seeds in cold water for 7 10 days, change the water once a day, or put the sack containing walnut seeds in running water to absorb water and expand the cracks, and then sow seeds.
