Planting seedlings early in spring is beneficial because the temperature is still low, and the seedlings are in a dormant state. The soil is moist, and as the temperature gradually rises, it promotes root development and increases the chances of successful establishment.
To protect the root system, several key measures should be taken: First, handle the seedlings carefully to avoid damaging the roots and minimize the time they spend out of the ground before planting. Second, when transporting seedlings over long distances, wrap the roots in mud and cover them with wet grass to keep them moist. Third, plant the seedlings as soon as possible after transportation to prevent exposure to wind and sunlight, which can cause dehydration and damage.
For broad-leaved trees, excessive branches and leaves can lead to significant water loss through transpiration, causing the seedlings to wilt. To reduce this risk, prune some of the branches and leaves according to the size of the tree. This helps maintain a balance between water absorption and loss, improving the survival rate of the seedlings.
A common practice is to use a phosphorus solution for root treatment. Mix 3 kg of superphosphate, 25 kg of loess, and 80 liters of water in a container to create a phosphate slurry. Soak the roots of the seedlings in this mixture before planting. This treatment encourages new root growth, enhances drought resistance, and ultimately improves the survival rate.
When transplanting trees, it's important to preserve the original orientation. If the seedling had a natural hook or direction on top, it should be planted in the same direction. This helps the tree adapt more quickly to its new environment.
When planting, fill the hole with well-rotted soil first, removing any stones or debris. After filling halfway, gently lift the sapling to ensure the roots spread out and make good contact with the soil. Then, pour root water, add a layer of loose soil, and compact it properly before continuing to fill the hole in layers.
After planting, assign dedicated personnel to manage and protect the seedlings. Prevent grazing and human interference. Once the seedlings are established, focus on weeding, watering, fertilizing, and pest control. Regular loosening of the soil and weeding can stimulate new root and shoot growth, ensuring healthy development.
