Introduction to the Culture methods and matters needing attention of Dendrobium "Flower of Father"

Dendrobium is a kind of potted ornamental flowers with many varieties, such as Dendrobium nobile, Dendrobium candidum, Dendrobium candidum and so on. Because of its peaceful temperament, it is a good choice as a gift to father. What about the "father's flower" Dendrobium orchid? What are the specific breeding methods and matters needing attention?

I. Culture methods of Dendrobium

1. Prepare soil

As the aerial root of Dendrobium has shallow roots, so the soil requirements are relatively high, the use of good drainage, loose and breathable soil is appropriate, you can choose stone, pine bark, sheep dung, etc., before disinfection should be done.

2. Plenty of sunshine

Dendrobium grows more vigorously in sunny places, so it is a good choice to keep it on the windowsill, but when the sun is strong in summer, shade should be carried out so as not to burn the branches and leaves of Dendrobium.

3. Watering method

Dendrobium likes the moist growth environment, but it can not be too humid, too humid will affect the respiration of the roots of Dendrobium, so in summer and autumn, water is watered every 2-3 days, and every 4-5 days in spring. Water control should be carried out in winter, even once a month.

4. Rational fertilization

In the growing period of Dendrobium, that is, from April to October every year, it is more appropriate to fertilize Dendrobium once a week, rotten cake fertilizer or peanut drum.

2. matters needing attention in the culture of Dendrobium

If Dendrobium is cultivated in the north, it is necessary to keep warm when the weather is cold in winter, because when the ambient temperature is below 5 ℃, it will lead to frostbite and even death.

When family maintenance of Dendrobium, pay attention to ventilation, indoor air is not circulating for a long time, it will lead to Dendrobium breeding a variety of diseases and insect pests, hindering the normal growth of Dendrobium. In addition, pay attention to the following points:

1. Pot soil replacement: for Dendrobium, which has been cultivated for more than 2-3 years, the plant is crowded, the root system is full, and the pot material has rotted, so it should be replaced in time. No matter evergreen or deciduous Dendrobium, change the pot after flowering. When changing the basin, you should hurt the roots less, otherwise the leaves will yellowed and fall off in case of low temperature.

2. Application of fertilizer: Dendrobium was topdressing in the second year after planting, twice a year, the first time in April, using one or more of cruller, oil foot, pig hair, bean dregs or human hair and cow dung, mud, add calcium magnesium phosphate fertilizer and a small amount of nitrogen fertilizer to mix evenly, after fermentation, apply thinly around the rhizosphere of Dendrobium to promote bud growth. The second time in early November, the same thin mud fertilizer was applied around the root of Dendrobium to keep warm for the winter.

3. Watering essentials: during the growing period of spring and summer, the pseudo-corm should be fully watered to accelerate the growth, but it should not be watered too much to avoid stagnant water to rot the root and cause the plant to die. Gradually reduce watering after September, so that the pseudo-corm tends to mature, which can promote flowering.

4. Pruning essentials: before Dendrobium germinates in spring every year, when harvesting Dendrobium, part of the old branches, withered branches and overdense stems should be cut off to promote the germination of robust new stems. If you plant it on a tree, you should also cut off the branches that are too dense so that the light transmission is moderate.
