Keel column, alias keel, cactus, dragon genus, plant triangular shape, multi-branched, blue-green, 4 meters to 5 meters high, a small spine edge, very short. In the summer, the keel pillars bloom white flowers, 4 to 9 flowers, clustered on the top of the thorn seat, open the night closed (potted plants are generally not easy to flower), berries small round, blue-purple, edible.
Multi-purpose cuttings are used for cutting, and the keel is a multi-slurry plant. When the cuttings are cut, they will flow out of the slurry, and they can be closed with plant ash, leaving the cool place for 7 days to 10 days until the plants shrink and then cutting.
One is to cut the keel cuttings, and the upper and lower incisions are closed with grass ash. The cutting length should be 20 cm to 25 cm.
The other is the branches taken from the branches of the keel, which can be cut after drying, but it is not easy to take root when it is too young. This kind of cutting only has small wounds at the roots, cutting roots quickly.
Cutting keel matrix needs to use vermiculite, pearl powder, pure river sand, no soil. Single planting cuttings can also be used, multiple plantings can be placed in cuttings, watered after cutting in, and only poured into the cuttings at the cuttings, so that there is sufficient sunshine. Rooting period as little as possible watering, do not do not pour, wait for 30 days to 40 days, you can take root.
After rooting, transplanting was carried out. The potted soil required 1/2 river sand and 1/2 loam to be mixed and then planted with 2% potassium permanganate water. The soil was disinfected and water was poured. Can be tied with a stick. When training, put enough sunshine, still need to control the amount of water, prefer dry not wet is better.
Keel pillars are varied, with a plexiform, three-cylindrical, and nine-cylindrical. The author believes that the Nine Column and the Twelve Columns are spectacular, and the plastic practice is:
When the nine-cylindrical plants grow to 20 cm to 30 cm, they are cut off with a sharp knife and immediately sealed with plant ash. After the plants grow branches, only the top three branches are reserved, one for each corner, and the rest erase. When the second layer grows to 25 cm to 30 cm, the top is trimmed again, and after the branches are born, three branches are selected, 3 in each corner, namely 1, 3, and 9 shaped keels.
The twelve-corner method is the same as above, except that when the 9-column grows to 20 cm to 30 cm, the top is trimmed, and three branches are further cultured, and one or three per corner are selected. The remaining small branches are erased along with their length and remain consistent in the tree.
Clustered plants grow to 40 cm to 50 cm in length or 30 cm to 40 cm in diameter, allowing them to grow naturally to form a long keel, but the stay should be orderly and undisturbed.
When the height of the keel column reaches 2m to 3m, many branches are formed, which can easily cause top-heavy instability. Therefore, the stick should be fixed in time.
The keel pillars need plenty of sunshine. The branches are blue-green. The leaves resemble fish phosphorus. They glow in the sun, and the crowds of people are standing in the air. The swords of the peaks are spectacular and are the best for potted flowers.
Keel columns are not cold, but they are drought-tolerant. They like to dry loam soils. They should be kept indoors in the winter in the north. They can be planted in the open in the south. They can also be used as fences. They are both green and beautifying gardens. In the summer, flowers and fruits can also be seen.
The keel column has the name of “universal rootstock†and can be used as an anvil with keel columns, which can be grafted with tiger acacia plums, crab claw orchids, exotic flowers, and colorful trees.
There were fewer keel pests, poor indoor ventilation, and vulnerability to spider aphid. The top of the branch was found to be reddish-brown with a mesh, and 1,000 to 2,000 times the omethoate spray was used. The amount should not be too large to prevent head injury. fester.
