Some people came up with a solution when they had no choice. They think that pleating is "tight", that is, the sheath is wrapped too tightly, so they boldly make sacrifices, simply cut the sheath with a knife, and then split it hard to both sides, fearing that it will be fixed with a rope again, and pleating is still right (like some people use arrows). The above is what the author saw with his own eyes, and more than one person did it.
The power of seed germination should not be underestimated. No matter how hard the land is, the roots will go down and the leaves will grow out, and the leaves will soon disperse when they see the sun. Does the leaf sheath of Clivia restrict the normal growth of leaves? It's unnatural. It is reasonable to say that even if the leaflets are trapped in the leaf sheath before stretching, they will gradually expand after growing, but this is not the case. It is incredible that some cubs of big animals have to run with their mothers to survive. Moreover, their mothers can also give birth to them because of their big size. However, nature is born, which is normal. It seems that the pleating of Clivia is not caused by external reasons.
The evolution of organisms is in the direction of better survival, otherwise this species will be eliminated. The existence of species is "natural selection". Among the materials we can see, observing the shape of wild Clivia is not as beautiful as our improved varieties, but nothing is uglier than pleating. I think those inferior species have long since been eliminated.
In hybrid breeding, although hybridization is complex, it is not chaotic, and it must follow certain laws, otherwise it will be eliminated naturally. Clivia pleating is probably a disaster caused by wrong hybridization.
Here, we can only use possibility, but we don't say the words very definitely. After years of observation, I discovered the essence of Clivia pleated. I found that the pleating rate of Clivia is related to its shape: the pleating rate of Clivia is inversely proportional to the length of petiole (neck), that is, the shorter the neck, the higher the pleating rate; It is proportional to the degree of round head, that is, the rounder the head, the higher the pleating rate; It is inversely proportional to body size, that is, the bigger the body, the lower the pleating rate; It is inversely proportional to the length-width ratio, that is, the greater the ratio, the lower the pleating rate.
If the above observation is correct, the excessive pursuit of short neck, ultra-wide neck and ultra-small neck may be the reason for the pleating of Clivia.
Other views:
The leaf pleating of Clivia is a normal physiological feature of the new generation of Cymbidium sinense, Cymbidium sinense and the old variety of Changchun Orchid. In other words, all these varieties or their genetic descendants have this feature. According to people's aesthetic point of view, pleating seriously affects the ornamental value of Clivia, and the leaves are in an unsatisfactory state.
Then, in addition to the above reasons, other varieties also appear pleating phenomenon. What is the reason? Experience shows that improper fertilization is one of the main reasons. A large number of basal fertilizer, edge fertilizer and solid fertilizer are applied, although the fertilizer effect time is long, fertilizer fermentation and fertility occur at the same time, which greatly exceeds the amount of fertilizer needed by plants, and this period of time lasts for a long time, resulting in long-term excessive fertilizer, abnormal absorption of roots and abnormal growth of leaves. From the observation of folded leaves, we can see regular phenomena. First, pleated leaves are not longer than normal leaves, but shorter and thicker than normal leaves. Second, brown leaves, if unfolded, are usually wider than normal leaves.
From the above analysis, it can be concluded that excessive fertilization is an important cause of leaf pleating. When it is found that the leaves of plants are pleated, measures should be taken in time to replace new humus soil and suspend fertilization until the new leaves are flat.
