The effect of excessive wind on capsid

Orchids in the recent period of neglect of management appeared the phenomenon of carapace and coating damage, some serious buds showed wilting, after analysis to find out the reasons, the following around these two phenomena to talk about solutions and preventive measures.

1. Carapace

The carapace is the protector of the immature orchid plant, which plays a role in supporting the growth and shaping of the orchid plant, and is the key to the growth of the orchid plant. Carapace premature wilting is a taboo in the process of orchid plant growth, and if it affects the growth seriously, it will provide a breeding platform for harmful bacteria and eventually lead to plant wilting and premature senescence.

In orchid cultivation and management, we have always thought that too dry or too wet will damage the carapace when the new grass is not mature, in fact, excessive or concentrated flow wind will also form the dryness of the carapace, although the air temperature is kept at about 80 degrees.

The small fan in our orchid room is always blowing, and is even with the basin surface. Recently, it was found that most of the new seedling shells near the center of the fan were dry and brown, which seriously affected the growth of the pseudobulb in the later stage.

The life span of carapace on mature orchid plants in the same year can be kept fresh for one to two years, and there is rarely three years of health. On orchid plants with a span of two years, carapace is generally kept fresh for two years, and there are few carapace fresh for three years. When the living environment is bad, the first manifestation is blackening or dryness, such as root system damage due to too dry or too wet, air too dry or too wet and so on. From this, we can see that the carapace signal, like the tonsil of the human body, will first become inflamed, swollen and painful when it encounters harmful bacteria infecting the internal organs, so as to attract people's attention. If it turns a blind eye, something worse will happen later.

Second, bract capsid

Bracts are layers of clothing wrapped in flower buds, and they play a very important role in flower bud gestation. Premature death is bound to affect the development and growth of petals and the later rise of flower stalks, and seriously lead to flower bud wilting or harmful bacteria infection and mildew. Whether the bract capsid is well preserved or not is the first factor to determine the opening of the flower stem, which should attract the attention of cultivation managers. Healthy bracts will be shelled layer by layer when the flower rod is pulled up, and the flower rod will grow rapidly within the period of validity, making the flower more attractive and meaningful.

Most of the flowers with five bract capsids of an ideal flower are healthy. The twist caused by the damage of bract capsid will affect the rise of flower stem and the display of flowers in varying degrees. Bring more or less negative to the overall sense of beauty.

III. Solutions and preventive measures

Under the blowing of concentrated wind, the capsid is easy to dry, and the slightly dried capsid will show a little rust color. When you find it in time, you should immediately adjust the wind direction and volume so that it can not blow directly. Generally, the slightly damaged capsid will keep from continuing to dry down, and the bract capsid will stretch out the second and third layers healthily in the later growth. If the loss is no longer aggravated.

Scientific and reasonable wind circulation is essential in cultivation and management. the power wind can choose about 1 meter above the high leaf, and the natural wind can be adjusted through the window, and don't forget the air humidification.

The water holding capacity of cultivated plants is better in the normal wet state, and it is not easy to be too dry or too wet for more than three days, otherwise the shell will be injured in varying degrees.

Careful observation combined with scientific and reasonable management is the key to cultivate orchids.

Postscript

During this period, the excessive wind directly blew my national fragrance Fengyun bud, cymbidium new product core butterfly bud, Lvxiaoliaomen new flower bud, national fragrance lily bud, Cang Yan element bud and so on. The carapace drying of Daichipin and Guangling butterfly grass seriously affected the growth and strength of the new grass.
