Using the large-plow furrowing method for clear-cut regeneration of black locust
1. Preparatory work. Large-plow furrowing means using a tractor to pull a large plow to furrow in a clear-cut black locust (Robinia pseudoacacia) site. A tractor with relatively high horsepower must be used. An ordinary iron plow for plowing farmland is sufficient, but a single plow is required. First clear branches and large stones from the site. 2. Plot selection. Large-plow furrowing requires concentrated, contiguous plots, a slope of less than 25 degrees, and a soil layer of more than 30 cm. 3. Technical requirements. The black locust root system is relatively shallow, the main root is not obvious, and the lateral roots are well developed. The main lateral roots are mostly distributed in the surface layer at a soil depth of 20-30 cm.
