1, planting: keel is very easy to survive, like humus-rich sand. If it is difficult to find this kind of sand, you can find some soft soil at will. The keel is not too demanding on the soil, and the general soil can support it.
2. Illumination and temperature: As the plants on the keel will turn yellow under strong direct sunlight, they should be kept in a semi-shady environment in summer and in the sunny place with indoor temperature above 10℃ in winter, and the flowerpots should be rotated regularly. In winter, keel can't be cultivated indoors in the north, which is easy to freeze to death due to frostbite.
3, maintenance: cologne is drought-resistant, watering should be appropriate. Water can be watered once every five days in summer. If the basin soil is too wet for a long time, it will cause rotten roots. During the winter dormancy period of 1-2 months, watering once will not dry up.
4. Fertilization: In order to make it grow well, apply nitrogen fertilizer once a month during the growing period, and it is best to use self-made fertilizer. After soybean or peanut is crushed, it can be buried in a flowerpot, or it can be soaked in soybean or peanut and then buried in the soil for fertilization. But the fertilizer should not be too thick, so as not to cause fertilizer damage and lead to rotten roots.
5. Propagation: The keel is propagated by cutting. Cut the branches above 10 cm, wash the pulp, dry for 12 hours before cutting (or cut directly after cutting, but the survival rate is slightly lower). A week later, when the new keel begins to lose water and wilt, pour some water, and the sand would rather be dry than wet, so as not to rot the cut. Can be placed in a semi-shady place, it is easy to take root.
6. Management: Keels grow fast and are easy to reproduce, and the management requirements are not strict. You can leave the branches or prune them at will, but each pruning should not be too long. It is best to wait for the keel to grow to more than half a meter before shaping and pruning.

Functions and uses of Longguzhu:
1. Ornamental value
There are many kinds of dragon bone columns, such as cluster, three columns and nine columns. The author thinks that nine columns and twelve columns are spectacular. The specific shaping method is as follows: When the nine-column plant grows to 20 cm to 30 cm, cut off the top with a sharp knife and seal it with plant ash immediately. After the plant grows branches, only the top three branches are left, one at each corner, and the rest are erased.
When the second layer grows to 25 cm to 30 cm, the top is cut off again. After the branches are born, choose three branches, three at each corner, that is, 1, 3, 9-shaped keel.
The angle selection method of twelve columns is the same as above, except that when the length of nine columns is 20 cm to 30 cm, the top is cut off, and then three branches are cultured, and each angle is selected as 1 or 3. Other twigs are erased with the increase of length, keeping the tree shape consistent.
2. Potting effect
When the tufted columnar plants grow to 40 cm to 50 cm or 30 cm to 40 cm, cut off the top and let them grow naturally to form a multi-headed keel, but the selection should be orderly and not disorderly.
When the growth height of the dragon bone column reaches 2 meters to 3 meters, many branches are formed, which is easy to cause top-heavy and unstable, and should be fixed with wooden sticks in time. Dragon bone column needs plenty of sunshine, the branches are blue-green, the leaves are like fish scales, and they will glow under the sunlight, with many bodies and sharp swords. Very spectacular, it is a good potted flower.
3. Home page function
Keel, in the application of home, not only has the function of eliminating evil, but also has a good purification function. For the newly renovated house between home and office building, it has a good adsorption effect on formaldehyde, benzene, radon, ammonia and TVOC.
However, more attention should be paid to planting keels indoors, because there are sharp thorns on the fleshy stems of keels, and the white milk in the stems is toxic, especially not eye-catching. Therefore, special attention should be paid to the placement of the keel at home to prevent children and the elderly from being stabbed and poisoned.
Moreover, the dragon bone flower is drought-resistant and sun-resistant, suitable for growing in sunny places, and not suitable for growing in dark places indoors, so the dragon bone flower placed indoors should be placed in the window near the sun as much as possible.
The flowers of the keel are big and domineering. The keel belongs to Cactus, which gives people the impression that it is a plant with strong vitality growing in the desert, so planting a pot of keel at home and sending it home adds a sense of domineering and adds a lot of vitality.
