Broad-leaved trees artificially promote natural forest regeneration technology

First, the operating points:
1. Artificially promote natural regeneration sites by ensuring that all mountain areas are not prohibited from burning dead seeds, seedlings, and saplings of the target tree species on forest land. This controlled burning helps maintain ecological balance and prevents the accumulation of flammable materials that could lead to more severe wildfires.
2. Use manual clearing methods in the woodland. The branches, twigs, vines, and ground cover in the felling area should be placed along the horizontal line of the hillside and accumulated into strips every 4 meters. This allows for natural decomposition, which reduces soil erosion and improves soil fertility over time.
3. Conduct regular tending of young forests, twice a year—once in summer and once in autumn. During these periods, focus on weeding, removing excess sprouts, and replanting open spaces with appropriate tree species according to ecological principles. This ensures a balanced and healthy forest structure.
4. Adjust the tree structure to support the growth of target species. When young trees reach 3 to 4 years of age, perform structural adjustments by thinning out weaker or smaller trees while keeping the stronger ones. Follow the "three cuts and three stays" principle to ensure even distribution. Aim to reserve 120–160 trees per acre, with an even spread across the area.
5. Implement timely thinning to encourage the production of mature wood. Promote natural regeneration through diverse tree species, complex structures, and high-quality management. During thinning operations, conduct thorough surveys, plan carefully, and assign dedicated personnel to ensure quality and long-term sustainability.
Second, the scope of application:
1. Recently harvested broad-leaved forest areas that have not been replanted.
2. Barren hillsides that still have sufficient numbers of seedlings, saplings, and sprouts of coniferous and broadleaf species.
3. Areas located within water conservation zones, soil and water conservation forests, riverbank protection forests, and scenic forests.
Third, economic benefits:
Artificially promoting natural regeneration is a method that follows the biological characteristics of trees and uses artificial techniques to restore forest ecosystems. It is cost-effective, supports multiple tree species, promotes rapid growth, increases biomass, and enhances ecological functions. Compared to traditional plantations, this method requires only one-third to one-fourth of the investment. Tree diversity can reach 30–50 species, which is 10–15 times higher than that of a plantation. The resulting plant community is more stable, with both positive and negative species evenly distributed, overlapping layers, and efficient use of water, nutrients, light, and heat. This leads to higher yields per unit area. Additionally, the forest’s ability to conserve water, prevent wind erosion, fix sand, and resist pests and diseases is two to three times greater than that of pure forests.
