Curing method:

It is forbidden to beat branches in young forests, and the bark shall not be damaged during tending, otherwise its growth will be significantly reduced. When the crown of Nanmu forest is completely closed, weeds under the forest are eliminated, and there are many pressed trees, tending and thinning shall be carried out. The weak lower layer tending method is adopted, i.e. the obvious pressed wood, double forked wood and the competitive wood around the excellent wood are cut off. The thinning intensity should be determined according to the specific situation. Generally, if the forest land is fertile and the initial planting density is large (such as 222 trees per mu), about 30% of the trees can be cut.
