Bonsai teaching: the high-pressure breeding method of Luohansong is worth collecting

It has a strong arrogant spirit, as well as Chinese culture "longevity", "wealth auspicious" and other implications, the pursuit of high-end garden landscaping owners often like to plant one or two Pinus tabulaeformis, in order to create their own "garden style" to add God's pen. Pinus tabulaeformis, as a slow-growing tree species, can not propagate rapidly, especially in large scale and beautiful shape. It is understood that in the market, engineering seedlings with a diameter of 10 cm or more mainly rely on imports.

Does Pinus tabulaeformis need 2 cm circle? In fact, the propagation of high pressure usually occurs after high temperatures in spring and after hot weather. It is important to pay attention to the balance between supply and demand of plants. It is best to grow faster with twigs, remove most of the branches and leaves, grow roots faster with sand beds, and pay attention to shading and moisturizing, and take root for about 2-3 months.

High pressure is a good way to obtain materials quickly. Compared with cutting propagation, high pressure can shorten the time. This is the common choice of ordinary couples.

The principle of high pressure is to use the plant cambium to produce callus in the destroyed or stimulated, this kind of tissue has the ability of regeneration and can fill the missing parts of the plant, such as xylem, phloem, root, stem and so on.

By peeling off the branches, the cambium will be destroyed to form healing tissue. For the upper plant, there are no roots, so the healing tissue will be triggered to take root.

When the water of the plant is transported through the xylem, as long as the mother plant in the lower part of the plant grows normally, it can normally supply water to the high-pressure plant without death, so the success rate is high.

However, there are still some noteworthy problems:

First of all, the length of girdling should not be too small. For those fast-growing varieties, it is easy to heal up and down, unable to reach the rooting mother.

Second, the higher the growth of the upper high-pressure plant, the more organic matter accumulates and the more energy it accumulates, the more energy it accumulates and the faster the root. As a result, the upper part usually requires the sacrifice of branches, and high pressure usually occurs in spring and summer.

Third, the lower part of the mother plant was cut off because of the phloem, and no organic matter could be obtained. If it takes too long, it will dry up. This will lead to "starvation". In this way, not only will the mother die, but also the high-pressure plants will not get water and death. Therefore, the solution to this problem is to use a separate seedling on the parent plant to provide organic matter, or to provide water with independent seedlings on high-pressure plants.
