Can beginning of autumn plant trees in the future?

Beginning of autumn can plant trees in the future, which can improve the survival rate of some cold-resistant trees.

Benefits of planting trees in autumn:

In autumn, the temperature drops gradually, the water transpiration is low, and the soil water content is stable.

Under the condition of soil temperature in Shang Gao, the roots of cold-resistant tree species planted in autumn can still grow again, so the survival rate is high. Planting in autumn should be carried out as soon as possible, and the leaves can be dropped.

Afforestation in autumn avoids the busy period of greening, which is beneficial to organize high-quality seedlings and reduce the project cost.

Precautions:

Tree planting in autumn and winter mostly adopts cluster technology, so not all tree species are suitable for afforestation in autumn and winter.

Usually in autumn, trees with long latent bud period and strong germination can be planted, such as poplar, willow, locust, Ailanthus altissima, Fraxinus mandshurica, etc., and the cold resistance of tree species should also be considered.

Planting trees in autumn and winter in northern China should be carried out after the trees begin to shed their leaves and before entering the dormant period.

During this period, the aboveground part of the tree has stopped growing, but the root system has not stopped growing. After transplantation, the root system can resume growth, which is beneficial to improve the survival rate.

Premature transplantation, vigorous aboveground metabolism and other activities, easy to lose water, affecting survival; Transplanting is too late and the ground temperature is low, which is not conducive to root recovery.

Planting techniques:

Trees are planted with bare roots. Before planting, 1/3 of the root system should be cut off, other lateral branches should be cut off again, and 1/2 to 1/3 should be cut short or Bo Tu. The bulb seedlings with soil can be lightly cut, and some leaves can be thinned to reduce transpiration.

The planting depth is 5-8 times deeper than that in spring? The soil should be compacted to prevent water loss caused by strong winds in winter.

Water immediately after planting, and sufficient water is the key to the survival of seedlings. When the weather is dry or windy, water it as soon as possible.

Within 3 to 5 days after planting, water is poured for 3 times continuously, and after the third water infiltration, the soil is piled on the tree foundation to form a 30 cm high soil pile, which is beneficial to wind protection, moisture preservation and root protection.

After planting, cultivate and fix the soil. For autumn and winter planting, DBH is 3? 5 cm young trees must be cultivated well after watering, and they should be planted on the ground to increase the seedling fixing ability of the soil.

For big seedlings, while cultivating the soil, it is necessary to do a good job of bracket fixation to avoid wind shaking, root injury or even lodging.

Pay attention to antifreeze, fire prevention and insect prevention, and make a crescent ridge 60 cm high at a certain distance from the seedlings in the windward direction; Remove weeds and sundries on the surface to avoid fire; Trunks below 1.3m should be whitened to prevent pests and diseases, and whitened with chemicals; 5 parts of quicklime+0.5 part of sulfur powder+20 parts of water.
