Culture methods and matters needing attention of potted white palm

White palm began to be used in potted ornamental plants at the beginning of the 20th century, and it has become very popular in Europe in the 1980s. White crane taro is regarded as an innocent flower, with the meaning of purity, serenity, peace and peace. White palm flowers are flawless and bring people a sense of serenity and harmony, so people believe that white palms symbolize good luck, especially according to the shape of their flowers. They are often used for indoor beautification, greening and decoration, and are often cultivated in pots. Generally speaking, it is harmless to simply keep it, as long as you don't eat it.

White palm is a kind of plant that is very popular in modern families. White palm can not only bring fresh air to the family, but also play a good fengshui condition. White palm has higher requirements for soil and temperature, so it is not easy to raise it. The following is to share with you the breeding methods and points for attention of white palm:

[culture method]

Matrix selection: White palm needs basin soil that is loose, drained and breathable. The culture medium should be prepared before getting high-quality seedlings. The matrix can choose ordinary northeast peat or imported German peat, but both should add 15% to 20% perlite and stir evenly, choose perlite with large particles, and be careful not to crush perlite as far as possible. The EC value of the prepared matrix is about 0.7mS/cm and the pH value is about 5.5.

White palm pot requires loose soil, drainage and good ventilation, can not use heavy soil, generally can be made of rotten leaf soil, peat soil mixed with a small amount of perlite as a substrate; planting with a small amount of organic fertilizer as base fertilizer. Because of its fast growth rate and large amount of fertilizer, liquid fertilizer should be applied every 1-2 weeks in the growing season; at the same time, sufficient water should be supplied to keep the basin soil moist, and water should be sprayed to the leaf surface and ground in the period of high temperature to improve air humidity. If the surrounding environment is too dry, the new leaves become small and yellow, and when they are serious, they wither and fall off.

Light control: White palm is more resistant to shade, when the light intensity exceeds 250w/m2, it is necessary to shade the white palm. In the northern region, 65% of the sun can be covered in summer, avoid bright light, otherwise the leaves will turn yellow and sunburn will occur in serious cases. White palm is more shade-resistant, as long as it has about 60% scattered light to meet its growth needs, so it can be cultivated in indoor places with bright scattered light all the year round. Summer can cover 60% to 70% of the sun, avoid bright light, otherwise the leaves will turn yellow, and sunburn will occur in serious cases. Greenhouse cultivation in northern winter can not shade or less shade. If the light is too dark for a long time, it is not easy to blossom.

Temperature control: White palm is a species that likes high temperature and should be cultivated in high temperature greenhouse. The most suitable daytime and night temperature for white palm is 20 ℃ ~ 21 ℃, and the highest temperature is not more than 24 ℃. If the daytime temperature is high, as compensation, the night temperature can be reduced appropriately. For example, if the temperature is 27 ℃ for 6 hours during the day, the temperature should be kept at 9 ℃ for 6 hours at night. Other cases in turn and so on. In particular, it should be noted that if the white palm is in a state of low temperature for a long time, it is easy to cause the leaves to fall off or be scorched yellow.

Humidity control: the most suitable relative humidity for white palm growth is 75%-85%. You should often use a fine-eye sprayer to spray water on the leaves and sprinkle water on the ground around the plant to keep the air moist, which is very beneficial to its growth and development. If the climate is dry and the air humidity is low, the new leaves will become small and yellow, and when they are serious, they will wither and yellow and fall off. If the humidity at night is more than 80%, be sure to increase the greenhouse temperature by 1 ℃ ~ 2 ℃ 1 hour before sunrise in the morning to 2 hours after sunrise to avoid infection.

White palm is a kind of species that likes high temperature and should be cultivated in high temperature greenhouse. The lowest temperature in winter should be 14-16 ℃ at night and about 25 ℃ in daytime. Long-term low temperature is easy to cause leaf shedding or scorched yellow. During the growth period, we should often keep the basin soil moist, but to avoid watering too much, the basin soil is moist for a long time, otherwise it is easy to cause rotten roots and plants withered and yellow.

Water management: White palm likes wet environment. The matrix should always be kept moist and cannot wait until the matrix is completely dry before watering. Dry and wet water management is not suitable for white palm, and it also increases the chance of root infection, which is not conducive to growth. The best way of watering is spraying at the top, but the drainage of the seedbed is better. The maximum EC value of spray water should not exceed 0.8mS/cm, otherwise it is disadvantageous to the growth of crops.

In summer and dry season, we should often use a fine-eye sprayer to spray water on the leaf surface, and sprinkle water on the ground around the plant to keep the air moist, which is very beneficial to its growth and development. If the climate is dry and the air humidity is low, the new leaves will become small and yellow, and when they are serious, they will wither and yellow and fall off. Watering should be controlled in winter, and the basin soil should be slightly wet.

Fertilization management: as the white palm has relatively more tillers, fertilization can be more. In the vegetative growth stage, the ratio of N to K sprayed with nutrient solution is 2: 1, and in the reproductive growth stage, the ratio of N to K sprayed is 1.5: 1, which can make the reproductive growth of white palm dominant and promote flowering.

[notes]

1. Improper lighting. White palm needs better light in winter and early spring, do not shade, and gradually shade when the light is getting stronger, if you enjoy it in the shade, do not directly expose it to the sun, otherwise it will cause discomfort due to rapid changes in the environment, such as wilting, yellow leaves, and even death.

2. The temperature is not comfortable. Generally speaking, this situation does not happen at this time, and it is easy to occur when the temperature is below 5 ℃ or higher than 35 ℃.

3. Humidity: White palm needs higher growth humidity, and if the air is too dry, it will cause leaf wilting, which can be solved by strengthening water spraying or environmental ground spraying, or covered with transparent plastic bags. however, when the light is good, it is necessary to have a little ventilation or open a mouthful of ventilation on the top of the plastic bag, otherwise the temperature in the bag will rise sharply.

4. Improper fertilization. Fertilizer should be applied thinly, do not apply thick fertilizer or raw fertilizer, and water once after applying solid fertilizer, it is best to use thin fertilizer instead of clear water, so that it generally does not produce fertilizer damage, and the plant grows luxuriantly.

5. Insect pests. If harmful mites are harmful, the leaves show bad symptoms such as wilting, gloss desalination, yellow blight and so on, which can be controlled by spraying special mites, such as triclofenac, Nisolan, pyridaben and so on.
