It's dragon blood tree. The key points of cultivation are as follows: humus soil, peat soil and river sand can be mixed 1 serving for cultivation and maintenance, and cultivated under the condition of 70~80% shading. Apply compound fertilizer 1~2 times a month during the growing period, keep the soil moist, and spray more leaves in summer to improve the air humidity, so that the leaves will be thicker, brighter and less prone to drying. In winter, it is necessary to keep the temperature above 8℃, and the soil in the basin should be watered less, but it is effective to keep the color of leaves and prevent dry tips by wetting the ground frequently and increasing humidity. This plant has beautiful leaves and is a good material for all kinds of indoor decoration. If the humidity can be properly reduced before entering the room to adapt to the dry environment, and water is often sprayed on the leaves after entering the room, you can enjoy it indoors for a long time and it is not easy to dry the leaves. Some plants damaged by indoor decoration can be recovered as long as they are moved back to the production site for a period of time if the damage is not serious, while some seriously damaged plants are difficult to recover and can be used for seedling propagation; For example, it is a pity that some people throw away their leaves after they have been damaged for a while. In fact, as long as the residual branches are cut off about 2cm below the budding branches at the upper end of the stem and the routine management is continued, new branches and leaves can sprout after a period of time. Warm light: Dracaena likes warm, humid and sunny environment, and can also resist shade. However, when raised indoors, if it is placed in a too cool environment for a long time, it will also cause the leaves to fade. Therefore, it is best to put the flowerpot on the windowsill in the southeast, so as to fully receive the sunlight. If the dragon's blood tree is kept on the balcony, when the sun is too strong in summer, the flowerpot should be moved indoors, especially at noon, and properly shaded, with a general illumination of 40-50% to avoid burning leaves in the hot sun. Dragon's blood tree likes warmth and is not tolerant of cold. Its optimum growth temperature is 20-28 degrees Celsius. If the summer is hot, the temperature exceeds 32 degrees Celsius, or the winter temperature is lower than 15 degrees Celsius, the Dracaena is dormant or semi-dormant. After the end of 10 in the Yangtze River valley and its south, Dracaena will be moved indoors to prevent early frost. Throughout the winter, it is best to control the room temperature between 10-20 degrees Celsius, not too low. At the same time, the potted plants should be placed on the south window sill, so that the sun can shine directly on the plants, and the orientation should be rotated regularly to make them receive light evenly. If there is no sunshine for a long time, you can turn on the light at night, and put the dragon blood tree under 40 watts of light for artificial lighting to ensure the beauty of the leaves. Put the dragon's blood tree in the curtain at night, block the cold air with thick curtains, or put the flowerpot in a warm place in the corner to safely spend the winter.
