How to raise the latest money wood?

Artemisia mandshurica is a popular excellent indoor foliage plant in recent years, also known as Yunmu, Artemisia mandshurica, Artemisia mandshurica, Cedar taro, Dragon and Phoenix wood, etc., for Portulaca oleracea perennial evergreen herbs, named because the thick leaves are neatly arranged like copper coins, the leaf shape is more beautiful, there is a certain ornamental value, let's take a look at how to raise money wood!

The growth habit of Artemisia mandshurica

Qianmu prefers sunny and warm, dry environment, drought tolerance, dampness and cold, and basin soil stagnant water. Although it can grow normally under the condition of semi-shade and scattered light, the leaf color will decrease, and the distance between stem nodes will be lengthened, which makes the leaves loose and not compact, affecting ornamental. Sensitive to high temperature, watering should be reduced when the summer temperature is too high, or it may cause leaf shrinkage and defoliation. In addition, pay attention to heat preservation in winter, keep more than 10 ℃ as far as possible, otherwise it is easy to freeze to death, which is suitable for growth from 20 ℃ to 32 ℃. Watering during the growing period should be "no dry, no watering".

The breeding method of Artemisia mandshurica

1. Ramet: in April, when the outdoor temperature was more than 18 ℃, take off the big Artemisia mandshurica plant, shake off most of the persistent soil, break it from the weak combination of tuber sheep, and apply sulfur powder or plant ash on the wound, and plant it in another pot. Be careful not to bury it too deep when planting, as long as the top of the tuber is buried 1.5-2cm under the soil.

2. Cuttings: cuttings can be cut with a single leaflet, a leaf axis plus 2 leaves or a single leaf axis. In terms of rooting effect in the coming year, the cuttings with leaves on the leaf axis can take root faster, sprout higher in the north, and it is easier to open into larger tubers. After cutting a single leaf on the mixed medium mixed with river sand and vermiculite, a rooting bulb can be formed at the base of the leaf after 10-14 days, and it can grow into a small plant after 2-3 months of cultivation, but the seedling rate is not high in general.

How to raise money wood well?

1. Soil: the basic requirement of Artemisia mandshurica for cultivation substrate is good permeability. The basic requirement of cultivation substrate is good permeability. The cultivation medium was mainly mixed with peat, coarse sand or washed cinder and a small amount of garden soil, and its PH value was adjusted to between 6 and 6.5, showing a slightly acidic state.

2. Temperature: Artemisia mandshurica does not grow well when the temperature is above 35 ℃ in summer, so it should be cooled by covering black net to shade the light and spraying water to the surrounding environment. It is best to maintain the greenhouse temperature above 10 ℃ in winter. If the room temperature is lower than 5 ℃, it is easy to cause cold damage and seriously endanger the survival of the plant. In late autumn and early winter, when the temperature drops below 8 ℃, it should be moved to a well-lit room in time, and the temperature should be kept between 8-10 ℃ during the whole overwintering period.

3. Lighting: Qianmu Xiguang and strong shade tolerance should create a sunny but shaded environment for it. Avoid strong light, especially avoid hot sun exposure after long rain and early sunshine in late spring and early summer and 5-6 hours of unsheltered strong light baking before and after noon in summer, otherwise it is easy to cause burns of newly drawn young leaves.

4. Moisture: during the productive cultivation of potted Artemisia angustifolia, the plants placed in the greenhouse should be sprayed with water once a day when the room temperature is above 33 ℃. Because the plant has strong drought tolerance, it is better to keep the basin soil slightly wet and dry, but the occasional excessive watering and fertilizer will not cause root rot. In winter, we should pay attention to spraying water to the leaf surface and the surrounding environment, so that the relative air humidity can reach more than 50%.

5. Fertilizer: Qianmu is more fond of fertilizer. In addition to adding appropriate amount of retted cake fertilizer or multi-component slow-release compound fertilizer to the cultivation substrate, 0.2% urea and 0.1% potassium dihydrogen phosphate mixture can be applied 2 or 3 times a month during the growing season, or 20-10-20 balance fertilizer can be applied at the concentration of 200~250ppm combined with calcium nitrate. When the temperature drops below 15 ℃, all forms of topdressing should be stopped so as not to damage the roots under the condition of low temperature.

6. Turning the basin: Qianmu turns the basin once every two years, in late spring and early summer. The basin soil should be drained and breathable slightly acidic soil, peat, coarse sand or perlite, slag and a small amount of garden soil and slow-release fertilizer can be used. Because of its large tuber and well-developed root system, it is suitable to plant in deeper flowerpots and put more stones and tiles under the flowerpots to facilitate drainage. When planting, the tuber can be exposed part of the soil surface, and spread a layer of ceramsite or pebbles on the basin surface to increase the ornamental effect.

Disease control of Artemisia angustifolia

1. Freezing injury

[harm] when the temperature drops below 5 ℃ in winter, coupled with the dampness of the basin soil, it is easy to lead to the collapse of plant-like young leaves due to freezing and cold, and when it is serious, it will cause tuber rot and it is difficult to restore vitality.

[control] during productive cultivation, the greenhouse temperature should be maintained at no less than 10 ℃ during overwintering, and the basin soil should be kept slightly dry.

2. Burns

[harm] in a hot summer, or sunny weather after a long rain, or potted dwarf plants that have just moved outdoors for restorative maintenance for a long time, are directly exposed to the sun, which can easily cause the fat and tender leaves to be burned. as a result, part of the leaves lose green and whiten, or the whole leaves are burned, and the necrotic parts turn brown and black in the later stage.

[prevention and control] avoid bright light, especially avoid the hot sun exposure after long rain and early sunny in late spring and early summer and the unsheltered strong light baking for 5-6 hours around noon in summer.

3. Brown spot

[harm] Brown spot disease often occurs on the leaves, the spot is nearly round, grayish brown to yellowish brown, the edge color is slightly dark. The disease is easy to occur under the conditions of high temperature, high humidity and poor ventilation. Prevention and control methods: when a small number of diseased leaves are found, they should be removed and destroyed in time, and 50% carbendazim wettable powder 600 times or 40% chlorothalonil suspension 500 times at the initial stage of the disease should be sprayed every 10 days for 3 times 4 times in a row. The control effect is better.

[prevention and control] after the beginning of summer, the plants should be moved to a semi-shaded environment in time, and the plants should be planted with shade as soon as possible because of the long rain and sunny days in late spring and early summer.

4. Scale insects

[harm] in an environment with poor ventilation and poor light, the leaves of the tree are vulnerable to the piercing and sucking of scale insects.

[control] during productive cultivation, 1000 times of chlorpromazine wettable powder can be sprayed during the peak incubation period of nymphs, and the insecticidal effect is good.
