The planting method and Propagation of Flowers-- money Tree

The money tree is native to the tropical (prairie) climate region with less rainfall in eastern Africa. It likes the environment where the temperature is slightly dry, half-shaded and the annual temperature change is small. It is more resistant to drought, but is afraid of cold, avoid strong light exposure, and is afraid of soil sticky weight and stagnant water in the basin soil. if the basin soil is not permeable, it is easy to cause its tuber to rot.

​

The soil is required to be loose and fertile, well drained, rich in organic matter and acidic to slightly acidic. The sprouting power is strong, after cutting off the thick compound leaves, the tip of the tuber will soon produce new leaves. Next, I'm going to tell you how to raise a money tree:

1. Environmental requirements for the cultivation of Chimonanthus amurensis

The soil in which the money tree is raised:

Because of the special climatic conditions of the original place of origin, it has formed a strong drought resistance, so the basic requirement for the 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.

Because of its large tuber, developed root system and long pinnate compound leaves, its growth should be observed in time during the growing season to decide whether to change the basin or not. Always maintain the good permeability of the cultivation substrate, in order to create a good root environment with good air permeability and water filtration. Check frequently during the rainy season, and when it is found that there is stagnant water in the basin, turn the basin and change the soil in time.

The temperature at which the tree is cultivated:

The suitable temperature for growth is 20-32 ℃, whether potted or planted on the ground, the average annual temperature change is small, and productive cultivation should be carried out in a greenhouse with controllable temperature. Every summer, when the temperature is more than 35 ℃, the growth of the plant is poor. Measures such as covering the black net to shade the light and spraying water to the surrounding environment should be taken to reduce the temperature so as to create a suitable environment with suitable space temperature and dryness.

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 transferred to the room with sufficient light, and the temperature should be kept between 8 ℃ and 10 ℃ during the whole overwintering period, which is more safe and reliable.

2. Fertilizer and water management of Artemisia mandshurica culture.

The tree prefers fertilizer. In addition to adding appropriate retted cake fertilizer or multi-component slow-release compound fertilizer to the cultivation substrate, the mixed solution of 02.0% urea and 0.1% potassium dihydrogen phosphate can be applied 2 times a month during the growing season, or 20-10-20 (20-20-20) with a concentration of 200~250ppm combined with calcium nitrate.

After the Mid-Autumn Festival, in order to enable it to survive the winter safely, the application of nitrogen fertilizer should be stopped and 0.3% potassium dihydrogen phosphate solution should be applied continuously for 2 to 3 times to promote the hardening and enrichment of its young leaf axis and newly drawn leaves. 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.

In order to protect the potted money tree, efforts should be made to create a wet and dry environment for it. In productive cultivation, the plants placed in the greenhouse should be sprayed with water once a day when the room temperature is more than 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%. After the Mid-Autumn Festival, we should reduce watering, or spray water instead of watering, in order to spend the winter safely in the newly drawn tender leaves yesterday. In addition, in winter, we should pay special attention to the basin soil should not be too wet, it is better to be too dry, otherwise under the condition of low temperature, too wet basin soil is more likely to lead to plant root rot, or even death of the whole plant.

3. Pot cultivation of Artemisia mandshurica

Potted trees like loose, fertile and well-drained sandy loam. Families can choose rotten leaf soil, peat soil and appropriate amount of perlite or river sand to form nutrient soil. Do not use clayey soil, otherwise the permeability is poor. Very perishable roots.

Potted money trees like sufficient scattered light and avoid strong light. After entering the spring, the light increases gradually. Pay attention to move the plant to a place with sufficient scattered light, too strong and easy to burn the leaves, especially when the new leaves are just sprouting. The light is weak in winter and can be placed in a sunny and warm place. In the maintenance, do not be too overcast for a long time, otherwise the newly drawn leaf axis is too long and soft, and the ornamental property is poor.

The suitable temperature for growth is 20-28 ℃. When the temperature is above 35 ℃, the growth is hindered, the ability of absorbing nutrients becomes worse, and the plant growth is poor, and it is better to be no less than 12 ℃ in winter, if it is lower than 5 ℃ for a long time, it may lead to chilling injury. If the soil moisture is too high, the bulb is extremely perishable.

Potted Artemisia mandshurica has strict requirements for water. Keep the soil moist during the growing period, although it is more drought-resistant, but the over-dry soil has insufficient water supply and the plant leaves are soft and sagging. It's bad for growth. Long-term too wet, poor ventilation, easy to rot roots. In winter, it is necessary to control the water, keep the soil dry and avoid watering too much. The root system and corm are easy to rot when the temperature is too low and too wet, which is the main reason for the failure of overwintering maintenance. When the air is too dry in summer and autumn, it is necessary to spray water to keep the plant moisturized.

The potted money tree is changed once every two years. Because the tuber of the money tree is huge and easy to get hurt, you should pay attention to take it out slowly, get rid of part of the persistent soil, and cut off the overlong root system, withered root and rotten root. After putting on the basin, the soil is gently compacted and watered once a day. In order to improve the permeability of the soil, loosen the soil regularly, but be careful not to damage the bulb, otherwise it is very perishable.

4. Breeding methods of Artemisia mandshurica culture

The money tree is used to sow and propagate, and it can also be propagated by cutting.

Leaf cuttings are commonly used for propagation, which should be carried out in the growing season. Using whole-leaf insertion, insert the lower part 1Accord 4-1 beat 3 into a dry sand bed or sand basin to keep the seedling bed moist and spray water to the leaf surface 2-3 times a day to improve air humidity.

After 3-4 weeks of cutting, small tubers began to form at the lower end of the petiole, and the buds began to grow after 3-4 weeks. It takes 6-8 weeks from cuttage to seedling emergence. Strong shading and high air humidity are the key points during cuttage. It can also be propagated by dividing balls. Often used as a potted plant, the potted soil should be mixed with river sand, peat and rotten leaf soil in the same amount, or mixed with river sand, peat and an appropriate amount of mature organic fertilizer.

When planted in a shade shed or greenhouse, it is necessary to maintain sufficient water in the growing season, and often spray water to the leaves, raise the humidity away from the air, fertilize twice a month, need more nitrogen, potassium, calcium and magnesium, and the leaves are easy to droop when potassium and calcium are insufficient. Appropriate reduction of moisture in winter, and pay attention to heat preservation and cold protection.

5. Matters needing attention in the cultivation of money trees.

① note that money trees like warm, humid climate, bright scattered light, shade tolerance, and avoid scorching sun. Not resistant to cold, easy to shed leaves below 2 ℃, and safe to survive the winter above 6 ℃. Like fertile and loose, humus-rich, well-drained soil, prefer fertilizer, avoid stagnant water, slightly resistant to drought.

② pays attention to the fact that the tree is light-loving and shady, so it is best to place it in a place with sufficient light but with some shelter, which not only meets the light, but also avoids the yellowing of the leaves caused by the strong light.

③ notes that the money tree is gluttonous and likes to be nourished by fertilizer. It is best to apply fertilizer twice a month at the stage of its growth and when the temperature is above 15 degrees Celsius. The kinds of fertilizers are sold in the flower market. But when the temperature is below 15 degrees, fertilizer should be stopped, otherwise the roots will rot and the leaves will turn yellow.

6. Prevention and control of diseases and insect pests in the culture of Artemisia mandshurica

Pay attention to prevent the brown spot of the money tree, this disease mostly occurs on the leaves, the disease 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: a small number of diseased leaves should be removed and destroyed when they are found. at the initial stage of the disease, 50% carbendazim wettable powder 600 times or 40% chlorothalonil suspension 500 times, spraying leaves every 10 days, continuous 3 to 4 times, the control effect is better.

The main results are as follows: (1) Diseases: the main harm is brown spot. When it is found that a small number of diseased leaves should be removed and destroyed in time, brown spot disease can be treated with 50% carbendazim wettable powder 600 times, spraying leaves every 10 days for 3 to 4 times, the control effect is better.

(2) insect pests: there are mainly shell insects. Scale insects can be sprayed with 1000 times of chlorpromazine wettable powder, and the insecticidal effect is good.
