What is the value of money? What about yellow leaves? What do you need to pay attention to in farming?

Artemisia mandshurica, also known as Yun Ye and Chimu, is called Portulaca oleifera. Portulaca oleracea is a perennial evergreen herb, which is named because its thick leaves are arranged neatly like copper coins. It is a popular indoor foliage plant in recent years. So what is the value of Qianmu? What if the leaves are yellow and soft? What do you need to pay attention to in breeding?

What is the value of money wood?

1. Ornamental value

The leaf shape of money wood is more beautiful, so it has a certain ornamental value.

2. Purification effect

Potted money trees can be placed next to televisions and computers to absorb radiation and can also be planted indoors to absorb substances such as formaldehyde to purify the air.

Second, what if the leaves of Chimonanthus are yellow and soft?

1. The cause of temperature

When the temperature drops below 5 degrees in winter, if the soil is also very wet at this time, it will directly cause the leaves of Artemisia angustifolia to fall down by freezing, and in serious cases, it will cause its roots to rot or even die.

Prevention and control methods: when raising Artemisia angustifolia in winter, the temperature must be controlled, the lowest temperature must be maintained above 10 degrees Celsius, and the dryness of the basin soil should be ensured.

2. Occurrence of disease

When money wood has a disease, there will be round disease spots on the leaves, the color is grayish brown to yellowish brown, usually in the case of high temperature, high humidity and poor ventilation.

Prevention and treatment: when the disease has been found, the diseased leaves should be removed in time to prevent the transmission between the diseased leaves. In addition, you can spray medicine to control insects, spray once every ten days, spray three or four times to achieve the effect of prevention and treatment.

3. Too much sunshine

In hot summer, there is plenty of sunshine, and they are easy to get sunburned. For several days in a row, cloudy days suddenly turn into sunny days, and they will not adapt. There is a similar situation, for a long time in indoor farming suddenly moved to the outdoor, then let the money wood suddenly come into contact with the sun, it is particularly easy to cause its leaves to be burned by the sun, and then yellow and soft.

Prevention and treatment: let the money wood properly bask in the sun, can not be suddenly exposed to the sun. Keep it indoors or in a semi-cool environment in summer. Shading should be done in time after continuous rainy days.

Third, what does breeding need to pay attention to?

1. 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.

2. Lighting: Qianmu Xiguang has strong shade tolerance, so it should create a sunny but shaded environment to a certain extent. 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.

3. 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%.
