What is Larch? Characteristics of larch

Larch (Larix spp.)It is a deciduous tree of the genus Pinaceae, which is the main forest component tree species of alpine coniferous forests in Northeast China, Inner Mongolia forest area, North China and Southwest China, and one of the three main coniferous timber forest species in Northeast China. Larch has a wide natural distribution, it is a cold temperate and temperate tree species, the most hardy among conifer species, and the vertical distribution reaches the upper limit of forest distribution.

It is a pine tree that loses its leaves in winter. Commonly known as larch.

1. Characteristics 1. Appearance: Larch is very tall and can usually grow to tens of meters. There are many plants that can grow up to 35m in height.

Its trunk is also very thick, with an average diameter of 60-90 cm. It does not have many side branches, and the foliage is not particularly luxuriant, but it is also very ornamental.

2. Color: When it is young, the bark is darker and dark brown. As it grows, the bark will slowly become lighter in color, turning grayish-white or grayish-brown.

When the fruit is not ripe, it is purplish-red, and when it is ripe, it turns purple-brown or yellowish-brown.

Second, the breeding method because it is very tall, so when it is raised, it is usually raised young plants, or some dwarf varieties.

1. Flower soil: It likes well-drained and thick flower soil. Do not grow on soils that are too sticky. When raising it at home, you should try to raise it with some sandy soil with high fertility.

2. Moisture: It has high requirements for water and grows best on slightly moist soil. It can grow in dry or slightly waterlogged soil, but it will be stunted.

3. Sunlight: It needs to be placed in a well-lit place. Because it is a light-loving plant, it grows better this way.

Do pines belong to deciduous plants.

A pine tree is not a deciduous plant, it is an evergreen plant. In autumn, the ordinary leaves will gradually turn yellow and wither, slowly blowing to the ground, eventually leaving a bare trunk, but pine trees do not lose their leaves in winter.

What kind of plant does pine belong to?

Pine is a coniferous evergreen of the pine family that belongs to the hermaphroditic family. The male bulb is solitary on the bud axis in the lower part of the new branch, and there are many stamens. Pollination in the current year can rapidly increase cones in the following year.

It generally blooms in spring, but the flowering time varies depending on the variety. You are here: The pine tree is a flowering plant. Pine trees are also monoecious plants.

If pollination can be done that year, it will bloom the next year. It usually lasts 4-8 days.

Is the pine tree a flowering plant?

The pine tree is a woody plant. The pine trees are tall and straight, and the needles are generally 2 needles in a bunch. Its main stem is very lignified, so it is typical of woody plants.

Do pines belong to woody plants.

The pine tree does not lose its leaves in autumn and winter, is evergreen in all seasons, has an extremely long lifespan, and has a strong vitality.

Whether the pine tree is deciduous or not.

The old leaves at the end of the pine tree will gradually turn yellow in autumn until they fall off. The pine leaves fall every other year, and new leaves grow the following year. Pine trees grow new leaves at the same time as they drop their leaves, so they always look evergreen.

The current location is an evergreen tree. Its leaves are thin and needle-like. In winter, there will be fallen leaves, but not in large numbers.

A small amount of defoliation is normal.

Summary. Pro, larch leaves Introduction: The leaves are inverted-lanceolate, apex pointed or obtuse, the upper midrib is not raised, the cones are purple-red when young, oval or oval before maturity, yellow-brown, brown or purple-brown, and the seeds obliquely ovate.

Larch (scientific name: Larix Gmelinii (Rupr.).) kuzen.

It is a pine family, a tree of the deciduous leaf pine, up to 35 meters high and 90 cm in diameter at breast height; The bark of the young tree is dark brown, the branches are oblique or nearly flattened, and the crown is ovate-conical and almost conical; The winter buds are nearly spherical, the scales are dark brown, the edges are eyelashes, and the apex of the scales at the base of the stinger has a long pointed tip.

Larch is the main buried tree species in the Xiaokuanling coniferous forest of Daxing'an, China, which is rich in timber accumulation, and is also the main tree species for barren mountain afforestation and forest regeneration in this area in the future. It can be used for building construction, civil engineering, electric poles, boats, boats, joinery processing and wood fiber industrial raw materials. The trunk can be extracted from resin, and the bark can be extracted from tannin gum.

Pine trees lose their leaves, and new leaves grow at the same time as they fall, so the leaves are evergreen all year round. When cultivating pine trees, it is necessary to give 3 to 4 hours of light in spring, autumn and winter, shading measures need to be taken in summer, watering needs to be increased in summer, and the rest of the season needs to wait until the soil is completely dry before proper watering and moisturizing.

Pine trees shed their leaves, and pine trees are evergreen trees that shed their leaves in all seasons and grow new leaves. And the leaf life will be slightly longer than that of deciduous tree species. The leaves of evergreen trees wither and fall and new leaves grow at the same time, so the leaves remain green all year round.

In the process of daily maintenance of pine trees, it is necessary to adjust the light according to the changes of the season, in spring, autumn and winter, it is necessary to give 3 4 hours of light, and after entering the summer, it is necessary to build a shade net above the pine tree to weaken the intensity of light or directly transfer it to a soft light environment to maintain to avoid wilting and yellowing of branches and leaves.

Pine trees are drought tolerant and do not require much water during the growing period, except for increasing the amount of watering in the summer, and waiting until the soil is completely dry during the season before watering properly. Be careful not to allow the potting soil to accumulate water, otherwise the roots of the pine tree will rot and blacken.

Pine trees have a low demand for nutrients during the growth period, so it is necessary to reduce the amount of fertilizer applied during the cultivation process to avoid the root system being burned by fertilizer. During the vigorous growth period, the diluted decomposed organic fertilizer can be applied every half month to supplement the nutrients needed for the growth of the pine tree.

First, the biggest difference between Pinus sylvestris sylvestris and larch is that the deciduous properties of the two are different:

Pinus sylvestris var. sylvestris evergreen tree;

Larch is a tree of the genus Larch.

Second, there is a clear difference in the shape of the leaves of Pinus sylvestris sylvestris and larch.

Pinus sylvestris sylvestris needles 2 needles are quietly bunched, stiff and straight, often twisted, 4-9 cm long, rarely up to 12 cm, mm in diameter, apex pointed, with fine serrations on the edges, and stomatal lines on both sides.

Larch leaves inverted-lanceolate, long centimeters, millimeters wide, apex pointed or obtuse, the upper midrib is not raised, sometimes there are 1-2 stomatal lines on each side, and 2-3 stomatal lines on each side along the midrib below.

Third, Pinus sylvestris and larch have different soil requirements.

Pinus sylvestris var. sylvestris is adaptable, xerophytic, and does not require soil moisture. The crown is sparse, the needles are scarce and short, the coniferous epidermis is keratinized, there are thick fleshy parts, the stomata are born in the depressions of the leaf folds, and the dry epidermis and lower epidermis are very thick, which can reduce the transpiration of the aerial parts.

At the same time, on dry sand dunes, the taproot is generally 1 2 meters deep, and the deepest is less than 4 meters, and the lateral roots are mostly distributed in the sand layer 10 50 cm from the surface, and the root system extends to the surrounding area, which can fully absorb the water in the soil.

It can grow well on the nutrient-poor aeolian sandy soil and the mountainous gravel soil with a very thin soil layer. More than 30 species of coniferous and broad-leaved trees have been planted on the sandy land of Zhanggutai, and only Pinus sylvestris var. sylvestris can adapt to the environmental conditions of different parts of the sandy land, and can grow even on the top of the mound with the worst conditions.

Larch has a high requirement for water, and grows vigorously on the north-trending gentle slopes and hilly areas with deep soil, fertile and well-drained. [2]

Larch is best suited to grow best in moist, well-drained, well-aerated soil conditions with deep and fertile soil, and can also grow on arid and barren mountainous sunny slopes or in perennially waterlogged wetlands or low-lying lands, but it has poor growth.

Introduction to larch growth.

Larix gmelinii is a cold temperate zone and temperate zone tree species, which has natural distribution and artificial cultivation in northern China, mainly distributed in Northeast China, and belongs to the Great Xing'an Mountains and the Small Xing'an Mountains. It is also distributed in Russia.

Larch growth cycle.

Hung Yen larch has strong photophilicity and is most suitable for growing on the gentle slopes of the north with deep soil and good drainage. It can also grow on dry and barren mountain slopes, but its growth is poor. Larch has a lifespan of 250-400 years.

Larch growth cycle management.

Temperature management: Larch is best planted in an environment of 7-8 degrees, requiring a minimum temperature of about 9 degrees, while the maximum temperature it can withstand is 28-33 degrees. Fertilization Management:

Larch potatoes are generally fertilized once a month, and they are dug and applied in a pit about 30cm away from the roots. Loosen the soil and weed it every 20 days, and the depth of the pure loose soil next to the spring should reach 5 cm.
