Planting trees in autumn is strict. From defoliation of trees to soil freezing, trees should be planted in autumn from 654381October1October to 654381October1October+065438+1October, which can alleviate the short planting interval in spring, frequent sandstorms and sandstorms.

Pay attention to the following points when planting trees in autumn:

Trees are required to be planted with bare roots. Before planting, the root system 1/3 has been split and seriously worn, so the root is cut off. Trees should be trimmed, and the main branches should be trimmed. The lateral branches should be trimmed to 1/2 ~ 1/3 again, or the leaves should be thinned to reduce transpiration.

2. The planting depth should be 5 cm to 8 cm deeper than that in spring, and the soil should be compacted to prevent wind-induced water loss in winter.

Water the seedlings immediately and thoroughly. The key drought or strong wind should be watered as soon as possible. Be sure to water it in 3 to 5 days, and water it three times. The third infiltration of water into the mound will be beneficial to wind protection, moisture preservation and root protection.
