Which planting method employs a bulldozer with a V-shaped blade to create seedling beds?

The method that employs a bulldozer with a V-shaped blade to create seedling beds is known as V-blade planting. This technique is particularly useful in forestry as it facilitates the creation of raised seedling beds, which enhances the conditions for the growth of young trees. By shaping the soil into a V-shape, the method optimizes water drainage and aeration, ultimately promoting healthier seedling development.

Additionally, the use of heavy machinery like a bulldozer helps cover larger areas quickly and efficiently, making it a practical choice for reforestation and afforestation projects. The V-shaped beds created by this method also help to protect seedlings from erosion and provide space for roots to develop adequately.

In contrast, strip planting involves establishing trees in rows or strips, while contour planting follows the natural contours of the land to reduce soil erosion, and bare-root planting refers specifically to a method where seedlings are planted without soil around their roots. These methods do not utilize a bulldozer with a V-blade setup, which distinguishes V-blade planting as the appropriate answer.
