Cultivation and maintenance methods of Paphiopedilum in Autumn

Paphiopedilum, also known as slipper orchid, Orchidaceae perennial herbs. Most of them are terrestrial species, and there are many hybrid varieties. It is one of the most popular cultivated orchids. It is a member of the foreign orchid family, but there are many varieties born and raised in our country. The common varieties are Magnolia, apricot and yellow, same color, purple, hardleaf, beautiful, leafy, ribbon, millet, snow white and hybrid Jack Tucken.

The biggest convenience of family cultivation of Aristolochia is that there is no special requirement for temperature, and it can grow normally when the room temperature is above 5 degrees. After the high temperature in the hot summer, Paphiopedilum wakes up from dormancy and enters the normal growth period. If you want to make Paphiopedilum blossom in the normal flowering period, autumn maintenance is very important. Autumn is the key period for Paphiopedilum to absorb nutrients and give birth to buds. According to the author's observation for many years, it is found that the budding time of some Aristolochia such as Aristolochia is basically synchronized with that of autumn chrysanthemum, and the bud of Aristolochia can be seen protruding from the leaves around September 20 every year. Although the bud and florescence are different due to different varieties of Paphiopedilum, topdressing fertilizer and careful maintenance of all kinds of Paphiopedilum in autumn are synchronous.

1. Before the first fertilization, loosen the soil on the basin slightly with a fine wooden stick, but do not hurt the roots.

2. Liquid fertilizer with the same proportion of nitrogen, phosphorus and potassium should be applied once a week, which should be thin rather than concentrated. For example, the application of granular fertilizer with nitrogen, phosphorus and potassium can be reduced to once every semimonthly.

3. Foliar topdressing was carried out on the leaves every 10 days and sprayed with 0.2% potassium dihydrogen phosphate to stop when the buds came out of the foliage.

4. Pay attention to waterlogging prevention. Paphiopedilum is a shallow root plant, the basin soil is too wet, it is easy to cause rotting root phenomenon.

5. Let the potted flowers of Paphiopedilum be raised by hanging, which is not only conducive to the ventilation of the potted soil, but also conducive to the expansion of plant leaves.

6. when the temperature reaches about 25 degrees, the plants of Paphiopedilum should be exposed to light as much as possible. And often turn the basin, so that all the plants can receive light, so that it can be conducive to the gestation of multiple buds of all plants in the basin.

7. in late autumn, when the outdoor temperature is below 10 degrees, potted flowers should enter the house in time to avoid the harm caused by cold wind and frost to the plants of Paphiopedilum.
