The culture method of Xianglong blood tree:

Lighting:

Family training can be placed near the south window, pay attention to prevent strong light around noon in summer, and close to the south window in winter, so that it can receive more sunshine and grow healthily.

Temperature:

The optimum temperature for growth is 20-25 ℃. When the temperature is lower than 13 ℃, it will enter the dormancy state. The lowest room temperature should be kept above 10 ℃ in winter.

Fat water:

It is necessary to keep the basin soil moist during the growing season, and too much or too little watering is disadvantageous to its growth. The fragrant dragon blood tree likes the air to be moist, so it is advisable to spray the leaves 2-3 times a day when the new leaves are born. During the peak growth period, rarefied liquid fertilizer can be applied every 2-3 weeks.

Change the basin:

The new plant needs to change the basin once a year, and the old plant needs to change the basin once every other year, and the time to change the basin should be carried out in early spring. The basin soil was mixed with rotten leaf soil or peat soil mixed with 5 river sand or perlite and a small amount of bone powder.

To breed:

In common cutting methods, cutting should be carried out under the condition of air temperature above 22 ℃, and high temperature is beneficial to early rooting. In addition, water insertion can also be used for reproduction.

Fragrant dragon blood tree, Dracaena fragrans also known as: Brazilian iron tree tequila family dragon blood tree is native to the Canary Islands in western Africa. Xianglong blood tree has a strong trunk, sword-shaped leaves, green and glossy, full of vitality. It is a very popular indoor foliage plant in the world.

Biological characteristics

Like hot, humid and sunny environment. The suitable temperature for growth was 1824 ℃, 2430 ℃ from March to September, and 1318 ℃ from September to March of the following year. The winter temperature was lower than 13 ℃ and dormancy, and the plants below 5 ℃ were damaged by freezing. Among them, Bolin Fugui bamboo can withstand 2 ℃ low temperature. Like wet, afraid of waterlogging. During the peak period of leaf growth, keep the basin soil moist, the air humidity is 70%-80%, and often spray water to the leaf surface, but the basin soil can not accumulate water. Watering should be controlled during winter dormancy, otherwise leaf tip scorch is easy to occur. It has strong adaptability to light, and the stems and leaves can grow and develop normally under the condition of sufficient sunlight or semi-overcast, but the color of variegated leaves becomes lighter or disappears under the condition of low light for a long time.

The soil should be rich, loose and well-drained sandy loam. The mixed soil of rotten leaf soil, culture soil and coarse sand is the best in potted plants.

Culture method

Cuttage culture is commonly used. From May to June, the mature and robust stem was cut into 5-10 cm segments and placed flat on the sand bed, keeping 25 ℃ room temperature and 80% air humidity. It can take root in about 30-40 days, and can be potted directly in 50 days. The new buds of the stem with 3 or 4 leaves can also be cut off as cuttings and inserted into the sand bed to keep high temperature and humidity and take root 30 days after insertion. It can also be cultured by water insertion and high pressure, but it must be carried out under the condition of more than 25 ℃.

Cultivation and management

Potted fragrant dragon blood trees are often used in 12cm pots and 25cm pots for three stems. Fertilize once every semimonthly during the growing period, or use "Huiyou" 20 Mel 8 Mel 20 with high potassium nitrate fertilizer for four seasons. Fertilization will be stopped when the indoor temperature is lower than 13 ℃ in winter. If too much nitrogen fertilizer is applied, the golden markings of the leaves are not obvious, which will affect the ornamental effect. The fragrant dragon blood tree is resistant to pruning, and the plant height and shape can be controlled by pruning. In order to make the leaf buds grow vigorously, the pot must be changed every spring, the new plant once a year, and the old plant once every two years. Usually cut off the aged and withered leaves in the lower part of the foliage.

Common leaf spot and anthrax hazards in pest control can be sprayed with 1000 times of methyl topiramate wettable powder. Insect pests are harmful to shell insects and aphids and can be sprayed with 1000 times omethoate EC.

Postpartum treatment

The fragrant dragon blood tree plant is tall and straight, elegant, full of tropical atmosphere. Several stems of different heights were planted into large potted plants and used to decorate the venue. The living room and lobby are dignified and elegant, full of natural interest. Small potted plants or water-raised plants adorn the windowsill, study and bedroom of the bedroom, making it more beautiful and elegant. In the process of storage and transportation, the fragrant dragon blood tree has the best temperature of 16: 18 ℃, relative humidity of 80% and 90%, and can endure 15 days in the dark. However, plants with temperature lower than 8 ℃ during storage and transportation are vulnerable to freezing injury, and low air humidity will cause serious necrosis of leaf margin tissue.
