A: Kiwifruit has a strong root-to-potential force, and the use of roots excavated at the time of site preparation or seedling promotion promotes sprouting of rootstocks, thereby saving a large number of seeds and shoots. The method is to cut the rough root of the pencil into a root segment of 10 cm to 15 cm, with the big head facing upward and the small head facing downward for cutting. The small head should be cut with a pruning shear, and the root can be planted by budding to form a plant. The survival rate of cuttings in the middle was highest.
