Can orchids survive when their roots are dry?
Potted friends who like to grow orchids in pots may have experienced that the roots of orchids are empty, and experienced potted friends may be able to solve the problem, while novice potted friends who have no experience in growing orchids may become helpless. So, Jack? Today, the editor will share this knowledge for you.
Orchid roots are dry and empty, generally due to poor air permeability in the basin, or because the basin soil is hardened, or because the basin soil is too wet or even stagnant water, of course, there may be many other reasons. The air permeability in the basin soil is not good, which leads to the reproduction and growth of microorganisms, which seriously hinders or inhibits the normal respiration of orchid roots. What is the real reason for the empty root of orchids? Next, please follow the editor to have an in-depth discussion.
First of all, if the potted orchid is in a state of lack of water for a long time, its roots will dry up, but it is often not serious enough to directly lead to empty roots. The most direct reason for the empty root is that the root system is unable to breathe and accelerate the growth of a large number of microorganisms.
From the analysis of the internal structure of orchid root, orchid is a typical Monocotyledon, and the subcortical cells are very active, there is a phenomenon of symbiotic root bacteria. From its cross section, it is not difficult to find that it is composed of outer root tissue, middle cortex tissue and inner central column.
As a novice who doesn't have much planting experience, they often raise orchids to death because of careless management, but they still don't know what's going on. Often wait until the change of the basin to find that the soil in the basin of Langen has been hollow, or even rotten. Even those who have some experience can not completely avoid the phenomenon of empty root and Langen in practical application. Although sometimes we see orchids growing gratifying, we may encounter the phenomenon of empty roots when turning or changing pots. Therefore, raising orchids is easy to say, but in fact, it is often a common problem faced by the majority of friends.
So, where is the essential inducement of empty root and Langen? It was recorded in the ancients that if a root does not touch the earth, its root will be empty. From this sentence we can roughly hear what it means. The key point is that the rotten root is not in close and sufficient contact with the basin soil, so the root system can not absorb water and nutrients normally from the basin soil. This is the essence of the empty root. So, is this really the case?
Modern practice has proved that empty root and rotten root does not necessarily mean that the root system has insufficient contact with the basin soil, because sometimes we find that even the root system exposed on the surface of the basin soil does not have the phenomenon of empty root. Then, what is the most essential reason for the occurrence of rotten roots and empty roots?
In fact, it is the microorganism improved by the editor at the beginning of the article, and this kind of microorganism is very harmful to the plant, and it is they that cause the phenomenon of empty root and rotten root. However, if Langen does not have enough contact with the soil, leaving gaps, these gaps will naturally become places or hotbeds for microbes to live in. And it is the existence of these microorganisms, so that the original intact Langen was gnawed, so there will be empty root, Langen phenomenon.
Now that we have found the reason for the empty root, it is time to answer the above question. In fact, if we ignore the empty roots of orchids, microbes will continue to gnaw at these roots until they are eaten up. However, it takes a process to nibble on all the roots. The orchid plant can survive in the short term, but in the long run, it will eventually die quietly after the root system has been gnawed away.
