How to cultivate Metasequoia glyptostroboides in bonsai Culture methods and matters needing attention

Metasequoia glyptostroboides as one of the national key protected trees, its conservation needs special care, especially the bonsai made by Metasequoia glyptostroboides is not only ornamental, but also can play a decorative effect, so how should bonsai metasequoia be raised? What breeding methods does it have? What are the points for attention? Let's follow the editor to learn about it.

How to raise bonsai metasequoia

1. Soil

Metasequoia glyptostroboides likes warm and humid climatic conditions, and most of them are born in places with gentle terrain, deep soil, moist or slightly stagnant water, so when choosing bonsai cultivation soil of Metasequoia glyptostroboides, we should choose acidic mountain yellow soil or purple soil, mixed peat soil and other breathable substrates.

2. Lighting

Metasequoia likes light, under the condition of sufficient light, the leaves of Metasequoia glyptostroboides are dark green and green, which will promote Metasequoia glyptostroboides to show vitality, so the bonsai can be placed outdoors to receive sufficient light, and the bonsai can be moved into the indoor windowsill with scattered light in winter.

3. Fertilization

Metasequoia bonsai should be moderately dwarfed, so base fertilizer can be applied before planting, and fertilization can be applied again when the plant begins to grow, not prematurely, because early fertilization will lead to "indigestion" at the pile head of Metasequoia glyptostroboides. It should be noted that in the later maintenance process, do not apply too much fertilizer to ensure the normal growth of plants, and the application of appropriate thin liquid fertilizer can promote the growth of fibrous roots and branches and leaves. Be careful not to hurt the roots.

4. Watering

Metasequoia glyptostroboides should be irrigated regularly after planting, and should be watered thoroughly at one time.

Culture methods and points for attention of Metasequoia glyptostroboides bonsai

First, the method of bonsai culture of metasequoia

1. Use flowerpots of the right size

When raising metasequoia bonsai, be sure to use flowerpots of the right size, which should not be too small, otherwise it will make its roots fail to grow normally, cause roots to rot, and prevent its new roots from growing, and metasequoia will die slowly over time.

2. Timely ventilation

Metasequoia glyptostroboides this kind of plant likes the breeding environment with good ventilation conditions. When cultivating Metasequoia glyptostroboides potted plants at ordinary times, it must be placed indoors with good ventilation conditions, and wood must be placed at the bottom of the flowerpot, and it cannot be put directly on the ground. Otherwise, it will be due to poor ventilation conditions, resulting in leaf shedding or root damage, so that the metasequoia in the pot can not grow normally.

3. Pay attention to pruning the root system

When cultivating Metasequoia glyptostroboides potted plants at ordinary times, we must pay attention to the pruning of the root system, because the root system of this plant develops very fast and will form a staggered density in the flowerpot. When people change pots in a single pot of water supply every year, they should take out its plants and remove all the decaying and aging roots from its roots, and then transplant them into new flowerpots. Only in this way can we promote the growth of new roots and make the growth of metasequoia more exuberant.

4. Appropriate watering and fertilization

Aquaculture metasequoia pot must pay attention to appropriate watering and fertilization, although it is a water-loving plant, but watering must not be excessive, can not let stagnant water in the flowerpot, otherwise it will also affect the normal growth of metasequoia. In addition, Metasequoia glyptostroboides this plant has different requirements for fertilizer, usually do not need regular fertilization, fertilization every two months, and the fertilizer must be thin liquid fertilizer.

II. Points for attention

1. What if the branches of Metasequoia bonsai are wiped out?

Put the metasequoia bonsai in the semi-shade. If you see that the soil moisture is too heavy, pull the plant out of the basin and put it into the basin after the water evaporates. In addition to change the soil, buy rotten leaf soil in the flower market, be sure to mature and disinfect. The original root will be cut off a small section of about 3 cm, after disinfection, or rooting agent treatment into the basin. Remove part of the leaves to achieve the purpose of reducing nutrient consumption. If the plant is too large, you can purchase a nutrient solution to provide nutrition directly.

2. Metasequoia bonsai roots are staggered and dense, how to separate them?

The bonsai root system of Metasequoia glyptostroboides does not need pruning. According to the growth of bonsai, the pots should be turned once every 2-3 years, and the roots that are too dense and too long should be pruned, which can be considered according to the following conditions. If the new root of the tree is underdeveloped and the root system is not covered with the bottom of the soil, the original basin can still be used and the root system that does not need pruning can be used. For the tree species with developed root system, if the fibrous root is densely covered with the bottom of the soil block, the larger basin should be replaced, the dense root system should be thinned, the old root should be removed, and a few new roots should be retained to turn the basin. Some old pile bonsai can be properly raised to increase its ornamental value when turning the basin. And trim off the old root and root tip part, cultivate to loosen the soil, in order to promote new root.

3. What happened to the falling leaves of metasequoia bonsai?

Metasequoia bonsai leaves three points to pay attention to: ① reasonable change basin, small basin is easy to have a lot of dead roots, rot after the formation of bacteria, that will cause disease to the new roots slowly die. ② ventilation and light, metasequoia like light ventilation, need to pay attention to the high temperature, the bottom of the basin must be made of wood, if placed on the ground will burn the root system is also the main reason for the loss of leaves. ③ fertilizes less and waters frequently, but does not accumulate water.

How to prevent insect pests from Metasequoia glyptostroboides

The main results are as follows: 1. The coffee codling moth produces one or two generations a year, and the larvae are damaged by the larvae into the stem, resulting in the withering of the branches, the plants can not grow and blossom normally, or the stems are eaten and broken. The prevention and control methods are as follows:

①, cut off the damaged twigs, and burn the withered branches.

②, insert the wormhole with wire, hook out or stab the larva

③, inject 80% dichlorvos or 40% omethoate into the wormhole, and seal the wormhole with wet mud to kill the larvae.

④, spraying 40% omethoate during incubation, or 80% dichlorvos EC 1000-1500 times, or 50% fenitrothion EC 1000 times

(2) the rose leaf wasp can produce two generations a year, and the larvae can cocoon in the soil to survive the winter. There is a clustering habit, often dozens of heads gather on the leaves to feed, and in severe cases, the leaves can be eaten up, leaving only thick veins. The female lays eggs on the top of the branch, which can wither and die. Prevention and control methods:

Removal of hatched larvae by ① and artificial connecting leaves

② and cocoon control in winter to eliminate overwintering larvae

③, spray 1000 times of 80% dichlorvos EC, or 800 times of 90% trichlorfon, 1000 times of 500 times of 50% fenitrothion EC, or 2000 times of 2.5% deltamethrin EC

3. Leafhoppers can produce 5-6 generations a year, overwintering as adults on evergreen trees such as Platycladus orientalis or in weeds. Nymphs or adults use their mouths to suck juice, so that the leaves appear light white spots, when the damage is serious, the spots are patchy, or stab the epidermis, so that the branches and leaves wither. Prevention and control methods:

①, clear the fall in the nursery in winter

②, leaves, weeds, reduce the source of overwintering insects

③, killing adults with black light rust

④, spraying 2.5% deltamethrin wettable powder 2000 times, or 50% fenitrothion EC 1000 times or 1000 times trichlorfon

4. Rust symptoms: fungal diseases. It mainly harms leaves and buds. After spreading leaves in spring, the disease began to occur, and yellow rust spores were produced on the back of leaves, petioles and veins, which broke through the epidermis and spread orange rust spores and invaded the plants. In early summer, a large number of orange or yellow-brown powdery summer spores were formed, which made the branches and leaves green and yellow, and the disease spot obviously raised. In severe cases, the leaves of the whole plant withered or the buds withered and shedded. Prevention and control methods:

①, combined with pruning, removing rust branches and leaves, concentrated burning or deep burial, reducing the source of infection

②, rational application of nitrogen, phosphorus and potassium fertilizer to prevent overgrowth, pay attention to ventilation and light transmission, do a good job of drainage, reduce temperature, and improve plant resistance.

③ sprays Baume 340 stone sulfur mixture, or 25% verapamil 1500002000 times, or 65% Dysen zinc wettable powder 50000600 times, or 75% oxidizing verapamil 3000 times

The main value of Metasequoia glyptostroboides

1. Economy

Metasequoia sapwood white, heartwood brownish red, light and soft material, straight texture, coarse structure, big difference in hardness between early and late wood, not resistant to water and moisture. It can be used for construction, sheet metal, papermaking, appliance making, modeling and interior decoration.

2. Gardens

Metasequoia glyptostroboides is a "living fossil" tree species and an ornamental tree species with autumn leaves. In the garden is most suitable for planting, can also be cluster planting, piece planting, can be used for embankment, lakeside, poolside, courtyard and other greening, can also be potted, can also be planted into pieces to create scenic forests, and adapt to evergreen cover plants; can also be planted in front of buildings or used as street trees. Metasequoia glyptostroboides has a certain resistance to sulfur dioxide and is an excellent tree species for greening in industrial and mining areas.

Metasequoia glyptostroboides is intolerant of barren and drought, purifies the air, grows slowly, and is easy to survive and maintain. it is very suitable to raise a bonsai metasequoia at home. I hope it will be helpful to you.
