How long is the life of metasequoia, and how long is the growth cycle of metasequoia

Metasequoia is one of the world's rarest relict plants. As far back as the Cretaceous period of the Mesozoic Era, metasequoia plants appeared on Earth and were widely distributed in the northern hemisphere. After the Ice Age, these plants were almost completely extinct.

In Europe, North America, and East Asia, metasequoia fossils have been found in strata from the Late Cretaceous to the Pliocene, and in the forties of this century, Chinese botanists found surviving metasequoia giant trees in Moudao Creek (Modaoxi) at the junction of Hubei and Sichuan, which are about 400 years old. Later, the remaining metasequoia forests were found in the Metasequoia Dam and Xiaohe in Lichuan County, Hubei Province, with more than 5,000 trees with a DBH of more than 20 centimeters, and a large number of tree trunks and felling pockets were found in the valleys and farmlands. Subsequently, more than 200-300 years old trees were found in Lengshui in Shizhu County, Sichuan Province and Luota and Ta Ni Lake in Longshan County, Hunan.

Very long, there is a very big and very old metasequoia in Moudao, Lichuan, Hubei Province, the age of the tree has reached more than 600 years, it is the world's oldest, the thickest metasequoia mother tree with the thickest DBH, so it is called "the first fir in the world", metasequoia and ginkgo biloba are gymnosperms, survived the ice age, known as a living fossil, a very powerful tree.

Metasequoia is a deciduous tree in the family Tadodiaceae. Endemic tree species in China.

Morphological characteristics: the height of the tree can reach 40 to 50 meters, and the diameter at breast height can reach more than 2 meters. The leaves are opposite, linear, flattened, soft, pale green, and are pinnate on shedding twigs, which fall with them in winter.

Monoecious, male cones solitary leaf axils, racemes or cones; Female cones are solitary or opposite, and the bead scales are alternately opposite. The cones are long-stalked, drooping, nearly round or oblong, centimeter long, slightly quadrangular and slightly angular, with scales woody and shield-shaped. The seeds are obovate, about 6 mm long, flattened, with narrow wings around them.

Distribution: The oldest metasequoia fossils appear in the Cretaceous sedimentary strata of the Mesozoic Era, when there were about 10 species of this group and were widely distributed in the northern hemisphere. By the early Tertiary period, they migrated from south to north to the Arctic region, and then to the south due to great changes in climate, reaching northeast China, Korea, and Japan in eastern Asia.

But after the Quaternary Ice Age, they almost all became extinct. In the 40s of the 20th century, Chinese scientists found and identified the borders of Sichuan, Hubei and Hunan in China, making this "relict plant" that was once thought to be extinct in the world spread rapidly to the world and was known as a "living fossil".

Years ago to hundreds of years.

Metasequoia some can live for seventy or eighty years, some can live to more than six hundred years, metasequoia adaptability is very strong, suitable for gentle terrain, deep soil, moist place, generally speaking, the purchased metasequoia seedlings can grow about one meter a year, the height of the usual metasequoia seedlings is about 40 centimeters, and careful maintenance can make it grow to 150 centimeters.

Metasequoia growth cycle.

Some metasequoia can live for seventy or eighty years, some can live for more than six hundred years, metasequoia is very adaptable, suitable for gentle terrain, deep soil, moist places, generally speaking, the purchase of metasequoia seedlings can grow about one meter a year, the height of the usual metasequoia saplings is about 40 centimeters, and careful maintenance can make it grow to 150 centimeters.

Metasequoia growth rate.

Metasequoia tree is also a fast-growing tree species, the growth rate is fast, and the requirements for the growth environment are very low, this characteristic makes it very dominant in urban greening, the adult plant can grow to about 40 50 meters, has a good ornamental value and economic value.

Metasequoia growth cycle management.

Temperature Management:Metasequoia grows in a warm and humid climate, cool in summer, snow in winter but not cold, and the average annual temperature of the production area is 13, the extreme minimum temperature is -8, the extreme maximum temperature is about 24, and the frost-free period is 230 days.

Fertilization Management:

1. When planting potted plants, we should apply basal fertilizer, and when planting in pots, we must first apply sufficient basal fertilizer, and we must pay attention to not letting the roots of the fertilizer metasequoia directly contact when fertilizing, otherwise there is a possibility that the roots will be burned.

2. After planting, it is necessary to water it once, and when the metasequoia slowly begins to grow, you can carry out a second fertilization.

3. It should be noted that fertilizer can not be applied during the period from planting to growing new roots, because there is no root system to absorb nutrients, which can easily lead to indigestion of fertilizer and is not good for roots.

4. After the new roots grow, you can apply some liquid fertilizer in an appropriate amount, which is conducive to promoting the growth of new roots.

5. In the growth period after the growth of new roots, fertilization should be applied frequently, and light fertilizer can be applied once in about ten days, remember not to apply thick fertilizer to ensure that the nutrients are sufficient to promote growth.

The growth rate of metasequoia is neither fast nor slow, if the maintenance environment is suitable, that is, it is necessary to ensure sufficient sunshine, suitable moisture, and the temperature is best kept at about 15-20, then the growth rate of metasequoia will be faster. Metasequoia can generally grow up to 40 centimeters a year, but if well maintained, it can grow about 1 meter or even a meter tall.

The growth rate of metasequoia is neither fast nor slow, if the maintenance environment is suitable, that is, it is necessary to ensure sufficient sunshine, suitable moisture, and the temperature is best kept at about 15-20, then the growth rate of metasequoia will be faster.

Metasequoia growing season.

Metasequoia's growing season is generally in spring, when the plants have just eased from the dormant period and begin to enter the vigorous growth period, and the growth rate is relatively fast.

How much metasequoia grows in a year.

Metasequoia can generally grow 40 cm a year, but if it is well maintained, it can grow about 1 meter, or even meter tall, and if it is an adult plant, it can normally grow to 40 to 50 meters tall.

Metasequoia growing environment.

Metasequoia is a light-loving tree species, mostly grows in mild climate, summer and autumn rain, humid places, strict soil requirements, suitable for growing in loose and fertile soil, very adaptable to the environment, can grow in soil, can also grow in shallow water.

Metasequoia is suitable for growing places.

Metasequoia metasequoia mostly grows in mild climate, rainy summer and autumn, humid mountain slopes, rivers or valleys, mainly distributed in the local areas of Lichuan, Shizhu and Longshan counties on the border of Hubei, Chongqing and Hunan provinces, and is vertically distributed at an altitude of 750 to 1500 meters.

Metasequoia growth environment requirements.

The requirements of the growth environment of metasequoia are to have enough light, and the temperature should be suitable, not too cold, it has strict requirements for the soil, suitable for growing in loose, fertile, well-drained deep soil, but also to ensure that the soil is moist.

How to make metasequoia grow fast.

Lighting:Metasequoia leaves can only stay green if they are given enough light, so they should be placed in a well-lit location as much as possible during maintenance.

Watering:Metasequoia prefers moisture, and it is no exception, so when maintaining, it should be kept moist and has a certain waterlogging tolerance, so it is better to water more than to let it lack water.

Fertilization:Metasequoia prefers flower fertilizer, except in winter, it can be applied at other times, the fertilizer is best to use liquid fertilizer, diluted and then added to the plant, the plant can absorb the nutrients in it well, for its own growth.

Metasequoia growing conditions.

Metasequoia likes warm and humid climatic conditions, suitable for growing in acidic mountain yellow soil, purple soil, suitable for its growth temperature of about 18, metasequoia likes light, and the growth environment needs sufficient light to grow well.

How to raise metasequoia.

The temperature of metasequoia cultivation should not exceed 24 degrees, when the growth is vigorous, to ensure a certain period of sunlight, usually need to provide enough water, is not conducive to long-term drought, it has little demand for fertilizer grinding chain, can be slightly top dressing.

Metasequoia watering. Metasequoia likes dampness blind royal grandson, and waterlogging tolerance is good, usually need to provide enough water, long-term drought is extremely unfavorable to its growth, adhere to the principle of seeing dry and wet, once watering to water thoroughly.

Metasequoia fertilization. Metasequoia can also grow in barren areas, but it can also be top-applied with a little fertilizer, which can be applied with appropriate fertilizer and can promote the growth of fibrous roots and branches.

Metasequoia pest control.

1. Rose leaf bee control method: remove hatching larvae with artificial leaves, control cocoons in winter to eliminate overwintering larvae, and spray divos or trichlorfon stock solution.

2. Rust prevention and control methods: combined with pruning, remove diseased branches and leaves, concentrate on burning or deep burial, reduce the source of infection, pay attention to ventilation and light transmission, do a good job of drainage, reduce temperature, and spray Baume or powdered rust.

Metasequoia home farming.

1. When metasequoia is maintained at home, it can provide flower pots of moderate size and drainable bottom, and plant them in loose, breathable, fertile and well-drained slightly acidic soil.

2. Metasequoia can be raised in the bright light indoors, watered in time after survival, basal fertilizer can be applied before planting, and fertilizer can be applied regularly during the growth stage.

Precautions for metasequoia maintenance.

Metasequoia bonsai roots generally do not need to be pruned, but usually need to be repotted every 2-3 years, if the root system is too dense and long, it should be pruned, remove the old roots, and keep a small number of new roots for repotting.

1. Temperature: It likes a cool environment, specifically between 13 and 20 degrees. It doesn't like too high temperatures, generally not more than twenty-four degrees, which is the extreme heat it can tolerate.

However, it has some cold tolerance and can tolerate low temperatures as low as -8 degrees Celsius, but try not to go too low.

2. Light: It is light-loving, and the requirements for sunshine are relatively high. Especially during the period of vigorous growth, it is necessary to ensure a certain amount of sunshine every day. However, too much light is not enough, and it is best to keep it in a semi-shaded environment in summer.

3. Watering: Metasequoia likes moisture, and its waterlogging resistance is relatively good. Wild metasequoia is also generally found in moist or waterlogged areas. Therefore, it needs to provide sufficient water in normal times, and long-term drought is extremely unfavorable to its growth.

4. Fertilization: It has strong adaptability to the soil, and generally speaking, it can grow in barren places. But try to choose a place with more nutrients, and you can also apply some fertilizer a little.

1. Reproduction: cuttings can be used. Cuttings can be made with hard branches.

Shoots can be collected in January and then planted in March. The length should preferably be between ten and fifteen centimeters, and it is best to soak it with rooting powder before insertion. If this step is used, then after about 15 to 20 days, new roots will be grown.

2. Pruning; Proper pruning of the branches will help its growth, because there will be some more messy branches, which will seriously affect the light transmission and ventilation. Intensive pruning can be done before the beginning of spring, with an intensity of between one-quarter and one-third of the total length of the canopy.

1. Diseases: "rust" occurs frequently and will spread in large quantities. It can be prevented and controlled by powdery rust, and it needs to be combined with auxiliary measures such as pruning, and the excess water should be discharged in time.

2. Pests: There are still many species, such as "leafhopper", "Spodoptera exigua", etc., and different types of grinding can be controlled with different kinds of pesticides.

1. Toxicity: It is non-toxic. Moreover, its purification is still good.

2. Whether it can be raised at home: Generally speaking, it can't, because it is an arbor with a relatively high height, but it can be planted in the courtyard.
