How to cultivate sand trees to grow faster?

This kind of tree grows slowly, and there is no good method at present, which has little effect on improving the growth environment of trees and soil fertility. The following information is for reference only.

Banded grain-refers to straight grain wood without systematic deviation between the longitudinal axis of wood and the main axis of trunk, such as Korean pine, larch, mucha, jujube, etc. Staggered grain-the grain direction is periodically reversed, that is, shifted to the right, such as Cinnamomum camphora, Madong, Daye and Taohuaruimu. Wavy pattern-Long wood cells regularly curl to the left and right sides of the chord surface without touching each other, showing waves, such as cherry, maple, birch, Angola rosewood, Indian tomato, Fraxinus mandshurica, etc. Qin back grain-also known as tiger skin grain-refers to maple, birch, peach blossom and other parts with obvious bumps when wood is cut into veneer or sawed into chord board. Flocculent pattern-The depressions interwoven with fibers are surrounded by a series of irregularities, and the horizontal dimension is larger than the vertical dimension, such as mechanical wood and birch. Black eye pattern-conical dents appear on the growth ring due to the distortion of the back of the wood fiber arrangement. When it is cut into veneer, there will be many small twisted tissues on the surface of veneer, such as maple, birch and chicken. Cross pattern-feather pattern, fishbone pattern, fountain fatigue, bottle dryness, squatting? /P & gt； Silver pattern-its radial surface has horizontal stripes, thin slices, ribbons, massive or irregular ray markings, which are shiny and reflective, such as oak, Cyclobalanopsis glauca and longan: Cyclobalanopsis glauca, Haloxylon ammodendron, Platanus acerifolia, South China wood, Betula platyphylla and Holly. Tapered pattern-refers to the annular wood with obvious growth, distinct layers and different colors, forming beautiful "*"-shaped patterns such as gray walnut, red bean tree and iron knife wood. Parabolic type-refers to the sudden change of wood with early and late transition and different growth densities. Chord-cut panels show beautiful parabolas, such as Fraxinus mandshurica, elm, beech, Manglietia and Pinus massoniana. Oblique flower cone pattern-the rotary cutting forms a certain angle with the main axis of raw materials (such as 45o) to make the plate form a beautiful pattern, which is famous for black walnut abroad. Color stripes-refers to sawing logs of wood with uneven color distribution into patterns with varied styles, and their colors are derived from pigments and lignin in wood, such as walnut (with dark brown stripes in heartwood), camphor (with purple stripes in heartwood) and Dalbergia odorifera (with black stripes in red heartwood). Xiang mu 1. Pine and Chinese fir In the past, pine was regarded as a low-grade commodity in people's minds. Now it has become a fashion for farmers to decorate wardrobe doors, dados, wall decorations, ceilings and solid wooden doors with pine logs. The "rosin" smell of pine trees reminds people of the beauty and freshness of the northeast forest. In addition, the furniture made of high-grade Chinese fir also exudes a very attractive charm in a faint fragrance. Second, the king of "Xiangmu clan": rosewood occupies an important position in "redwood". It is noble, in addition to hard wood, beautiful wood grain and slow growth, another main feature is that it can emit a quiet wooden atmosphere for a long time. Third, the "Cedar" root carving A few years ago, a cuckoo root carving appeared in Taihang Mountain, and the fragrant Millennium Baiya root carving only attracted people's attention in the past year or two. It is characterized by natural red and white wood and thick curly modeling texture, which also brings a pure and simple forest atmosphere with a strong cedar fragrance. Among the foreign flowers and trees imported by Dutch Cedar in the past two years, there is a kind of green bonsai called "Dutch Cedar", which is particularly popular. This noble green leafy plant, which is more than one foot high, can emit a unique fragrance, which is really rare among "foliage plants". Putting a pot indoors can not only enjoy the green leaves and miniature forests, but also smell the flowers all year round, which is really wonderful. 5. Clove Wood As we all know, lilacs are in full bloom and their fragrance can float out for 100 meters. Clove wood is not only hard and beautiful, but also gives off a good fragrance. For example, the craft desk lamp made of lilac wood, under the baking of light bulb, will give off a rich aroma, giving people a double aesthetic feeling of vision and smell. 6. camphor wood is currently in some furniture stores, and camphor wood furniture (part) is in short supply. Most buyers said: "buying camphor wood furniture is a purpose, and more importantly, it is moved by its natural aroma." Knowledge Q&A of Wood for Furniture In production, wood is often divided into softwood and hardwood, while in furniture factories, many kinds of wood are often collectively referred to as hardwood and softwood. What are the real meanings of these four appellations? Wood commonly used in production comes from conifers and broad-leaved trees. Because cork material is generally soft, it is also called cork in production. But this cannot be generalized. Some softwoods, such as larch, are still hard. Because hardwood is hard and heavy, it is also called hardwood. Because there are many kinds of broad-leaved trees in production, they are collectively called miscellaneous trees. Among them, light and soft materials are called soft impurities, such as poplar, paulownia and balsa. Hard and heavy materials are called hard impurities, such as oak, white oak, Schima superba and Liquidambar formosana. When you buy wood, you use common names, such as Alnus cremastogyne, the first name is Rob Chai, and the second name is Watermelon. Is there a unified commodity name? As a commodity in production, processing and utilization, wood must have a unified name. The Ministry of Forestry has designated the names of 26 kinds of commercial timber. With the development of production, more and more species are exploited and utilized. Because of this, on the basis of the original 26 species names, more than 200 species have been developed and expanded, which still plays a huge role today. However, user-defined commercial timber tree species names are confused with classification names and common names (local names). For example, the machine-made wood you mentioned is also called radish firewood and watermelon, which are different names for the same tree species. Because of the different names, the price classification of tree species in different places actually spans the difference between the second and third categories, which has brought great economic losses to manufacturers. So a unified commodity name is very important for our furniture factory. In fact, as early as the early 1980s, the country divided nearly 8,000 commercial timber species provided in production into 24 1 commodity timber species and gave them standard names respectively. In the standard name of each commodity wood, the standard name and common name of tree species are listed accordingly, and the Latin scientific name is attached, which is one of the basic standards of national wood and is uniformly implemented throughout the country. Therefore, the commercial timber in China has a unified commodity name. In the answer to the last question, what is the difference between the name of commercial timber and the name of commercial timber tree species? There is a difference between commercial wood and commercial wood species. The former belongs to one category, including one or several commercial timber species in different genera of the same family or all commercial timber species in the same family, such as "Chestnut", including all commercial timber species in Castanea of Fagaceae, while the latter only refers to one of the commercial timber species, and the two cannot be confused. What are the grade categories of commercial timber forests produced in China at present? As mentioned above, there are nearly 800 kinds of commercial timber commonly used in China's production, which are divided into 24 1 commodity timber, and these 24 1 commodity timber are divided into five categories according to the principles of materials, reserves and development and utilization, namely, first-class timber, second-class timber, third-class timber, fourth-class timber and fifth-class timber. At present, the commonly used tree species in the furniture industry are selected as follows for reference when purchasing: first-class wood: Korean pine, cypress, yew, camphor tree, nanmu, ebony, plaid, Dalbergia odorifera, rosewood, boxwood, Cyclobalanopsis glauca, hickory, walnut, beech, neem, fragrant pile, manchurian ash and catalpa bungeana. The second kind of wood includes Cryptomeria fortunei, Cunninghamia lanceolata, Fokienia hodginsii, Torreya grandis, Castanopsis eyrei, Cyclobalanopsis glauca, Quercus acutissima, Sang Mu, Jujube, Cortex Phellodendri and Fraxinus mandshurica. Three kinds of wood: larch, spruce, pine, hemlock, ironwood, bauhinia, Dalbergia, Sophora japonica, birch, chestnut, Schima superba and maple. Four kinds of wood: Liquidambar formosana, Alnus cremastogyne, Pu Shu, Dalbergia Dalbergia, Betula platyphylla, Eucalyptus rubra, Eucalyptus albiflora and Paulownia. Five types of wood were put forward: Populus davidiana, Populus davidiana, Pterocarya stenoptera, Baliu, Huang Tong, Ilex pubescens and five hundred persimmons.
