Know the prevention and control methods of edible fungus diseases, and analyze the causes of folds in the leaves of Cymbidium.

Some flower friends find that their magnolia leaves have wrinkles, in this face-looking era, folds naturally make flower friends uncomfortable, want to find the cause, and then solve this problem. There are many popular theories about the folds of magnolia leaves, but no one has been widely recognized.

1. The folds of the leaves of Cymbidium are wrinkled. If the leaves are new, they will blossom, while the old leaves are caused by overweight (this statement is consistent with 2).

two。 Improper fertilization is one of the main reasons for the folds of Cymbidium leaves. Apply a large amount of base fertilizer, edge fertilizer, solid fertilizer, although the fertilizer effect is long, but the fertilizer after fermentation, fertility occurs at the same time, which greatly exceeds the amount of fertilizer needed by the plant, and this period lasts for a long time, which results in a long-term surplus of fertilizer. make the root in an abnormal state of absorption, resulting in abnormal growth of leaves. From the observation of pleated leaves, we can see a regular phenomenon: first, pleated leaves, no longer than normal leaves, are shorter than normal growing leaves, and thick and hard. Second, the browning leaves, if unfolded, its width is generally wider than the normal growth of leaves.

After it is found that the leaves of the plant are pleated, timely measures should be taken to replace the new humus soil and suspend fertilization until the new leaves grow flat.

3. The normal physiological characteristics of individual varieties are normal in Cenozoic Finch, Henglan and Changchun Orchid "Dye Factory" and other varieties.

In other words, all these varieties or offspring with their genetic genes have this trait. According to people's aesthetic point of view, pleating seriously affects the ornamental value of magnolia, which is a kind of unideal state of leaves.

Of course, there are some flower friends who hold other views, such as low temperature and water shortage, but these views are relatively unlikely, because some gentleman orchids are in excellent condition, but the leaves are wrinkled, so it is unlikely to be the problem of low temperature and water shortage.

The editor is more inclined to the variety characteristics of individual varieties, there are many flower friends of the gentleman orchid is a hybrid variety, it may contain some genetic genes, the appearance of these genes is not fixed, maybe there is no problem at the beginning, but wrinkles appear in the later stage.
