Is there a future for planting 30,000 golden silk trees?

Can you grow golden silk nan in Huaibei area of Anhui Province?

Zhejiang can be planted. The wood is mainly from the genus Phoebe zhennan, and the color of the wood is generally yellow with light green, with exceptions, some are yellow-reddish-brown. The crystals in the golden silk nanmu are significantly more than ordinary nanmu, the surface of the wood is shining golden in the sun, and the golden filaments emerge, which has a supreme and noble elegant atmosphere.

First, the soil is suitable.

When planting goldenrod, it is necessary to choose suitable soil. It prefers to grow in well-drained, breathable soil, and it needs to be fertile enough, so apply a sufficient amount of basal fertilizer before planting. Note that you can't use too heavy soil, which is not only not conducive to the growth of the root system, but also has poor drainage ability, and it is easy to rot the roots.

Second, the climate is suitable.

It is best to choose a suitable time for planting, and it is recommended that you plant in warm and humid weather. In the southern region, you can choose to plant in mid-November and around February and April in spring, and try to plant when it is cloudy. It's okay to have a light rain when planting, as long as it's not too dry.

Naturally grownGolden silk nanmuIt takes 100-150 years to become a tree, and 50-60 years after artificial cultivation.

Under natural conditions, it generally takes 30 years to start growing golden silk (golden yellow texture grows in the trunk), and grows at a rate of 1-2% per year, the standard of timber is that the core material occupies more than 80% of the entire trunk, and when it reaches about 95%, it is the best state of the tree, and the high-quality wood even takes hundreds of years, so there is a saying that the golden silk nanmu has become a hundred years old, and the artificially planted golden silk nanmu needs 50-60 years to grow.

Golden silk nanmu

It prefers a warm and humid environment, but it is also resistant to heat and cold. The average annual temperature of the origin is about 17, and the annual rainfall is 1400-1600 mm, which is mostly distributed in shady and humid valleys, mountain depressions and river ditches, and can tolerate intermittent short-term flooding. It grows best on deep, well-drained, neutral or slightly acidic alluvial or loamy soils, and poorly grows in arid or poorly drained areas.

It is a neutral shade tree species, which is shade-tolerant in juvenile stage, and often grows poorly under full light, with obvious taproots, developed lateral roots, and root germination and tillering can grow into large-diameter timber.

Due to the increasing scarcity of resources, at present, most of the wild tree species of Prunus chinensis are listed as national protected species.

At present, the initial growth of artificial planting Nanmu is much faster than that of natural forests. A 13-year-old plantation is compared to a 20-year-old natural forest.

The average annual growth of DBH, tree height and volume of the Quangong forest was 3 times, times and times faster than the natural growth, respectively.

Nanmu aliases: Huang Nan, Bai Nan (Fujian), Zhennan (Sichuan).

Scientific name: Phoebe Bournei (Heml.))yang

Family name: lauraceae

Nanmu is a precious timber tree species in China, and is famous for its excellent material at home and abroad. In ancient buildings, such as the Ming Tombs in the suburbs of Beijing, there are nanmu pillars that two people hug together, which are durable and do not decay. In the past, Phoebe chinensis was mostly naturally scattered in mixed forests, showing sporadic and small patches.

The provinces (autonomous regions) south of the Yangtze River, through more than 20 years of afforestation practice, have initially mastered the growth characteristics and afforestation technology of Phoebe chinensis.

Morphological characteristics. Evergreen tree, up to 40 meters, diameter at breast height, straight trunk, grayish-white-brown bark, irregular shallow longitudinal fissures. The twigs are hairy. Leaves leathery, narrowly elliptic, obovate-lanceolate or obovate-elliptic, pinnate veined on the entire margin, concave above, raised below, densely pubescent.

Flowering in April, panicles axillary, flowers yellowish. From October to December, the fruit is ripe, the drupe is ovate-oval, black, the perianth petals are persistent, erect, and the base of the drupe is covered.

It is distributed in Sichuan, Guizhou, Hunan and Fujian provinces (regions) in China. It can be cultivated in all provinces (regions) south of the Yangtze River and even Taiwan Province.

Biological characteristics.

The growth of golden silk nan wood is slow, and its growth law makes zhi its large instrument late, and the vigorous growth of golden silk dao nan needs to be 60-90 years, so it will take at least 100 years to become a pillar material.

Golden silk nan, is a very precious high-quality good material, and its growth law makes the big pot late (the vigorous growth of the ** stage takes 60 years) because the luster of the wood is very strong (especially in the planing of the obvious bright spots, some people according to this for the golden silk nan), even if not painted, the more you use it brighter. The bark is thin with dark punctate pores; There is a black annular layer where the inner ephelium meets the wood.

Because the earlier Nanmu was mostly a large material, and the tree had few straight knots, the texture was smooth and not easy to deform, and it was not rotten or moth-eaten for thousands of years, so it ranked first among the white woods in addition to hardwood, and its wood value was also above some hardwoods.

What do you do when you plant it, many of us here have allocated it to throw it away, planted, managed, carefully cultivated, and when you grow back, it has nothing to do with you a dime, and it has become a second-class protected plant of the state, and if you don't approve it, you will go to the cell for free accommodation. I still have dozens of Nanmu now, the big diameter is fifty or sixty centimeters, and only one golden silk Nan of about two cubic meters is two meters away from the old house, and it is approved if there are potential safety hazards. It took more than a year to get it approved, so what's the need to plant it?

Generally speaking, the time for the propagation and sowing of seedlings is before and after the light snow, because before and after the light snow, there will be green to dao black, which is the golden silk nanmu species has matured, at this time, we have to collect some fruits, and then we will screen out some full-grained fruits for planting, that is to say, we will have a large number of germination of the seeds of the golden silk nanmu before and after the beginning of spring, and then we can sow seeds.
