Nan and other species. Is a large tree, up to 30 meters when mature, its hard wood, expensive, and more for shipbuilding and palaces. The largest existing Nanmu Hall is the Lingling Temple in the Ming Tombs, and there are a total of 60 giant pillars in the temple, all made from the entire root of Nansi. Phoebe is extremely precious and has been included in the list of China's national key protected wild plants. And Xiao Bian to learn about Nanmu, take a look at Phoebe pictures .
Growth characteristics
Phoebe, shade-tolerant tree species, suitable for warm climate, moist, soil
Fertile areas, especially in the valleys, mountains, lower slopes, and riverside terraces, where the soil is deep and loose, well drained, and on neutral or slightly acidic loamy soils, grows particularly well. Deep-rooted tree species have strong sprouting power at the root and are resistant to intermittent short-term flooding. Long life, less pests and diseases, can grow into large diameter wood.
In juvenile period, the top buds are developed, the apical dominance is obvious, the trunk end is straight and strong, the side branches are thin and short, the canopy is thick and dense, and the entire canopy is pointed. In the prime period, as the high growth slows and the lateral branches expand, the canopy becomes bell-shaped, but the canopy remains thick. The top buds of the saplings are formed three times a year and three new shoots are drawn, namely winter buds - spring shoots - summer shoots - summer shoots - autumn shoots - autumn shoots. The growth of spring shoots is generally slow, and summer shoots and autumn shoots grow rapidly. Especially in the middle and early June (summer shoot period), tip shoots can grow 30-40 centimeters in 10 days, with an average daily growth of 1.5-2.0 centimeters, which is the highest peak in the whole year. There was also a peak of growth from August to September, but it was not as fast as the former. The growth of the two peaks accounted for more than 70% of the total annual growth. The DBH growth is mainly from May to November, and its growth accounts for 70-90% of the total annual growth.
According to the analysis of wood (Fujian Sanming): General natural Phoebe, the initial growth is very slow, 20 years old, the growth of height and diameter at breast height is only 5.6 meters and 4.1 centimeters, to 60-70 years after birth, before reaching a vigorous growth period. The growth of Nanmu trees is the fastest in 50-60 years, the diameter of breast diameter is the fastest in 70-95 years, and the volume of trees is the fastest in 60-95 years. In particular, the volume of the timber, between 60-95 years of growth accounted for 89% of total tree trunk growth, 90-95 years of growth, accounting for 25.5% of total trunk growth. It shows that Nanmu has the characteristics of rapid growth in the later period. However, in the plantation forest, the growth of Nanmu is much faster than that of natural forest. Compared with the 20-year-old natural forest, the 13-year-old plantation forest had an average annual growth of the diameter, height and volume of the plantation that was 3 times, 2.3 times, and 7.1 times faster than the natural growth. The root growth of P. nanmu is better during the juvenile period, and the main root can penetrate deeper into the soil and the number of lateral roots is also greater. Located in shaded valleys, mountains and rivers. The distribution area is located in the western part of the subtropical evergreen broad-leaved forest. The climate is warm and humid with an average annual temperature of about 17°C. The average temperature in January is about 7°C, and the annual precipitation is 1400--1600mm.
The soil is yellow earth with purple sand shale and limestone weathered. Deep in the soil, fertile, well-drained neutral or slightly acidic alluvial soil or loamy soil grows best; in dry and thin or poor drainage, poor growth. Phoebe is a deep-rooted tree species with a neutral shade. It has a long life span. It has not seen a significant decline after 300 years of life. The main root is obvious, and the lateral roots are well developed, and the roots can grow into large diameter materials. Infant shade is sheltered, three times a year. Phoebe grows at a moderate rate and reaches a vigorous growth period from 50 to 60 years. Phoebe seed is a multi-embryo type, with 2 to 3 seedlings per seed. Flowering from May to June and fruiting from November to December.
Fruit harvest
Phoebe communis is propagated with seeds. After the fruit is harvested, the exocarp is peeled off. The seeds are oily and have a short lifespan. After drying, they can be sown. If spring sowing the following year, wet sand storage is required. Seedling period needs shading, when the seedlings grow into true leaves can be transplanted or transplanted, generally 1 year seedlings can be planted out of afforestation. Such as green seedlings, can be changed for 3 to 5 years. Large seedlings must be planted with soil and cut off some of the leaves. When planting, choose a warm, moist and fertile environment. Phoebe bloomed in April, and the seeds matured before and after the “snowâ€, and the pericarp changed from blue to blue-black. Choose the best mother tree more than 20 years old, cut the fruit branches with a hook knife or a branch cutter, and take the fruit.
Fruit processing
The collected fruits should be treated promptly. The method is to put the fruit in a basket or a bucket to shake it, remove the peel, rinse it with clean water, put it in the shade, avoid exposure, and dry it slightly to store it. Generally 100 kg of fruit can be seeded 40-50 kg. Seed purity 92-99%, 1000-grain weight 200-345 grams, field garden germination rate of 80-95%. Seeds with high water content (20-40%) are prone to dehydration and cracking, moldy leaves of the cotyledon, and loss of germination power. Therefore, the treated seeds must be immediately layered and stored in moist river sand. If germination is required, it can be stored in a place with high temperature or sunlight, so that the seeds start to sprout before and after the “Springâ€, so that the seed can be sown several days earlier.

Electrolytic copper is a non-ferrous metal with very close relationship with human beings. It is widely used in electric, light industry, machinery manufacturing, construction industry, national defense industry and other fields, second only to aluminum in the consumption of non-ferrous metal materials in our country.
Copper is the most widely used and widely used in the electrical and electronics industries, accounting for more than half of the total consumption. For a variety of cables and wires, motor and transformer windings, switches and printed circuit boards.
Used in the manufacture of machinery and transport vehicles for the manufacture of industrial valves and fittings, gauges, sliding bearings, molds, heat exchangers and pumps.
In the chemical industry is widely used in the manufacture of vacuum, distillation pots, brewing pots.
In the defense industry for the manufacture of bullets, shells, guns and other parts, each producing 1,000,000 rounds of ammunition, the need for copper 13-14 tons.
In the construction industry, used as a variety of pipes, pipe fittings, decorative devices.
