The entire shoot is buried horizontally in the soil, allowing it to take root and develop into seedlings. This method is similar to cuttings, but instead of using short branches, longer shoots are used. These long branches contain more nutrients, which greatly enhances their ability to root. Once rooted, each shoot typically survives and can produce several seedlings. This technique works particularly well for tree species that have a low survival rate when propagated through other methods, such as Populus tomentosa. However, one drawback is that the distribution of seedlings tends to be uneven, leading to lower yields per unit area and less uniform growth.
The burial method is commonly used, but it's important to ensure the right depth of planting. Another approach is to place the twigs flat on the nursery bed, spacing them 20 to 25 cm apart. A small pile of soil is then placed over each twig, encouraging root development. Between each pile of soil, 1 to 2 buds are left exposed to sprout into new seedlings.
Compared to traditional buried seedlings, this method results in a more even distribution of plants. When the seedlings reach a height of 20 to 30 cm, careful cultivation of the soil around them is necessary. Once they grow to about 50 cm tall, a sharp shovel is used to cut off the base of the shoot, separating each plant and helping them establish a complete and independent root system. This process ensures healthier, stronger seedlings that are better prepared for transplanting or further growth.
