What issues should be paid attention to seedlings
In afforestation, planting seedlings is a common practice. The technique of planting seedlings in place not only ensures a higher survival rate but also promotes better growth during the same year after planting compared to un-planted seedlings. This method helps the young plants establish themselves more effectively in their new environment.
Nursery stock planting involves temporarily burying the roots of seedlings in moist soil. This practice is often used when seedlings cannot be planted immediately after transplanting, serving as an auxiliary measure to prevent root dehydration. Studies have shown that certain tree species, such as poplar, camphor, and ginkgo, along with fruit trees like citrus, peach, and plum, are well-suited for this method. However, species like buckwheat, which have low water content during dormancy, tend to have lower survival rates when planted. Therefore, it's essential to assess each tree species' specific needs before deciding on planting methods.
Seedlings can be categorized into two types: temporary planting and winter storage. For those that cannot be planted for extended periods, temporary planting is a suitable option. The process involves digging a trench in a well-drained and shaded area, approximately 30 cm deep and 50 cm wide. Seedlings are placed in rows within the trench, and their roots and lower stems are covered with 15–20 cm of fine, moist soil. Firming the soil helps reduce water loss due to wind. It’s important to avoid excessive coverage, as this can lead to overheating and root rot, while too little soil may not provide sufficient moisture.
For fall planting, winter storage of seedlings is another effective approach. A well-drained, shaded, and leeward location should be chosen, and a trench should be dug perpendicular to the main wind direction before winter sets in. The size of the trench depends on the seedling size—typically 30 cm deep and 50 cm wide for first-year seedlings, with deeper trenches for larger ones. On the windward side of the trench, a 45-degree wall is constructed. Seedlings are then evenly placed on the sloped surface, allowing their roots to extend into the trench. After covering the roots and lower stems with moist soil and compacting it, the soil moisture should reach about 60% of its maximum holding capacity. The soil must be free of weeds or other materials that could cause overheating or decay, ensuring the seedlings remain healthy throughout the winter.
When selecting sites for temporary or overwinter planting, it’s crucial to choose a sheltered, shaded, and elevated location to prevent waterlogging and premature sprouting. Minimizing root exposure during handling and maintaining root moisture are key to increasing the survival rate of planted seedlings. These practices ensure that seedlings are ready for successful planting in the spring.
