Medium-mature variety of golden crown seedlings bred in Japan. This strain includes Tianjin light budding variety. This tree is very strong, with young branches upright and big branches open. The crown is large, which is not suitable for high density planting. High germination rate and medium branching ability. After the branches are leveled, it is easy to slow out the short middle branches to form flower buds. After 3 ~ 4 years of planting, it bears fruit with axillary bud habit and high fruit setting rate. The long, medium and short branches of young trees can blossom and bear fruit, but the bearing branches are easy to weaken. Compared with the female parent Jinguan, buds germinate, bloom, stop spring and fruit ripens earlier. When pruning young trees, we should pay attention to the opening angle of main branches, shorten the extension heads of various backbone branches, and try to cut them lightly, slow down or transform other branches that do not affect the development of trees. Attention should be paid to timely retraction and renewal of drooping and weak fruit branches. Other cutting methods can refer to the gold crown trimming.
