Dragon whisker iron is another name for dragon blood tree. Its leaves are long and thin, bright green, and the plant type is beautiful, which is a good choice for home decoration. However, when there is such a basin of dragon whisker iron at home, how can we carry out daily maintenance? Please read on with me with questions!
Breeding method (basic knowledge): the best breeding time: outdoor breeding is suitable for April to August every year, indoor breeding can be carried out all year round, but the temperature needs to be kept between 20-30 ℃ to facilitate the growth of new roots.
The best growing soil: the requirement of longxutie to the soil is relatively high. The culture soil should be loose, fertile, well drained, and rich in organic matter. Generally, 5 parts of garden soil, 3 parts of rotten leaf soil, 1 part of rotten organic fertilizer and 1 part of river sand are mixed. When the soilless cultivation method is used for cultivation and management, the matrix can be fully mixed with vermiculite, perlite and peat soil.
Requirements for growth humidity: longxutie likes a warm and humid environment. Watering can be properly controlled to keep the basin soil moist.
The best growth temperature: the most suitable growth temperature is 20-28 ℃, if the temperature is over 32 ℃ in summer or below 15 ℃ in winter, the tree will be in dormancy or semi dormancy. Therefore, it is necessary to shade properly in high temperature in summer, and move into indoor breeding in winter in time to ensure that the room temperature is not lower than 8 ℃, so that it can survive the winter safely.
Best growing light: longxutie not only likes warm, humid and sunny environment, but also can withstand shade. It is suitable to place the flowerpot on the windowsill in the southeast direction so that it can fully receive the sunlight. In summer, proper shade should be provided. Generally, the illumination is 40% - 50%.
The precautions for cultivating longxutie with self raised longxutie: applying fertilizer: when using soilless cultivation, it is mainly to apply nutrient solution. If the cultivation quantity is small, it is not necessary to specially prepare nutrient solution, but to use the "red plum" and "Golden Moon" brand nutrient solution sold on the market. According to the instructions for use, add appropriate water, mix well, and then irrigate. Alternatively, every 30 to 40 days, the surface substrate can be planed and granular slow effect fertilizer can be applied once.
Watering points: water every 3-5 days to keep the substrate moist. In summer, most areas are hot and dry. You can spray water on the leaves with a fine hole watering can at 10:00 a.m. and 6:00 p.m. every day to protect the beautiful and bright color of the leaves.
Main points of pruning: it can be pruned into "t" type plant type and short cut branch.
1. Cut into "t" type plant type: make the main pole with the lower defoliated part into "t" type main pole, carry out flat cutting at the appropriate height of the plant, keep the new branches and leaves on the top of the main pole, wipe off the side buds on the main pole at any time, after a period of practice, it can be formed.
2. Short cut and branch storage: this method is suitable for some thin and weak species of Dracaena, such as fine leaves, colorful, gold (silver) edge, rich and precious bamboo, etc. That is to say, for the plants that have taken off their leaves for many years, 2-3 lateral buds should be left and right at appropriate positions for cultivation, and these buds should be different in height. At the same time, we should strengthen the management of fertilizer and water so as to form a full and scattered plant type.
Basin soil replacement: loosen the soil once a month in the growing season of longxutie to ensure that its root is always in a good state of permeability. If any ponding is found in the basin, it shall be removed as soon as possible, and the basin soil shall be turned over and replaced after being dried. In general, as a small and medium-sized plant in family potting, it can be turned once a year when it leaves the house in early April to meet the requirements of its annual growth on soil fertility.
Key points of propagation: the propagation of longxutie is generally carried out by cutting and pruning. It can be carried out from April to August every year, and can be carried out indoors all year round.
1. Pile cutting: it can be directly broken off by hand to remove 1 / 2-2 / 3 of the lower leaves, and directly inserted into clean river sand for water permeability, temporarily avoiding strong light.
2. Whole plant cutting: after short cutting, the leaves are removed first, and then the cuttings are watered in clean river sand. After that, the air humidity should be kept at about 70%, and the new plant will grow in one month.
Disease and pest control: the disease and pest control of longxutie can be divided into two parts: disease and pest.
1. Diseases: the main diseases in the seedling stage of longxutie are leaf spot and anthrax. When the disease is serious, it will form leaf blight and seriously affect the growth of seedlings. It can be sprayed with 70% wettable powder of mancozeb or 600-800 times solution of 50% methyltobuzin for 7-10 days, 3-4 times in a row, with good effect.
2. Insect damage: the seedlings of dragon blood tree are mainly damaged by red spider, which is a mite pest, mostly clustered on the back of plant leaves, netting shelter and sucking liquid juice. After being harmed by it, the leaves will fade, wither and even fall off, which will lead to the death of plants. It can be sprayed with 20% dicofol emulsion and 800-1000 times water, or with 50% dichlorvos emulsion and 1000-1500 times water, once every 7 days, 3-4 times in total, which can play a good role in killing and controlling.
The experience of cultivating longxutie: in order to make it not grow too tall, we can control the watering properly and keep the pot soil moist when we pump new shoots in spring. During the dormancy period in winter, fertilization should be stopped and watering should be controlled. Generally, it should be kept indoors for the winter. It can be watered once every 10 days and a half months to keep the basin soil slightly dry and moist, so as to make it safe for the winter.
