Method of selecting saplings

The method of planting trees and post-maintenance are important, but the selection of seedlings can not be ignored. Here, the Municipal Bureau of Landscape Architecture briefly introduces the following three methods of selecting common plants in the urban area of our city, so as to facilitate the citizens to choose their own saplings.

Trees (such as Luan tree, Italian poplar with red leaves, etc.). ): The trunk is straight, without obvious bending, with no more than two minor bends, and without dry decay and unhealed mechanical damage. The height of branch point is 2.5m-2.8m, the crown is full, the branches are evenly distributed, there are no serious pests and diseases, and the color of evergreen leaves is normal. Developed root system, no serious pests. When transplanting, the size of root system or soil ball should be 8- 10 times that of seedling DBH.

Shrubs (such as Lagerstroemia indica, Bauhinia, etc.). ): The root system is developed, the growth is robust, there is no serious pest, the shrub is symmetrical, the branches are distributed reasonably, the height should not be less than 1.5m, the clustered shrub has at least 4-5 branches, and the trunk of the shrub with trunk should be obvious.

Hedge seedlings (such as honeysuckle, red-topped rose, rose, etc. ): The height of coniferous evergreen seedlings shall not be less than 1.2m, and that of broad-leaved evergreen seedlings shall not be less than 50cm. The seedlings have plump tree shape, dense branches and leaves, normal development, developed roots and no serious pests and diseases.
