3. The growth habits and origin of Jin Si Nan

Jin Si Nan is a warm and humid environment, but heat resistance and cold. The average annual temperature of the origin is about 17 ° C, and the annual rainfall is 1400-1600 mm. It is mostly distributed in the wet valleys, mountain depression and river ditch, which can tolerate intermittent short-term flooding. The neutral or slightly acidic seductive soil or the soil of the soil layer is the best. Nanmu is a neutral partial yin tree, and the age of shades resist. Its main roots are obvious, the side roots are developed, and the roots can grow into large diameter materials.

Golden Silknan belongs to the shade -resistant tree species, which often grows poorly under full light. Pleasant warm and humid climate and more humid environment. Deep root, strong budding, slow growth. long life.

Jin Siunan grew from the subtropical wet valleys and rivers by the subtropical wet valleys and rivers, which are 1,000 to 1500 meters above sea level. Among them, the best quality is mainly distributed in Sichuan Sichuan, Emeishan, and places where Sichuan and Yunnan. It is mainly distributed in the wet valleys, mountains and rivers in the subtropical area of u200bu200b1000-1500 meters above sea level in Sichuan and Guizhou.

Those who are beautiful in Nanmu may form the patterns of landscapes at Xiangyang. The wood is hard and corrupt, and since ancient times, “water cannot be soaked, ants cannot be acupoint”.
