What happens when the petals of an orchid are upside down? Orchids have several petals

I don't know.

Orchid epiphytic or terrestrial herbaceous, leaves several to many, usually born at the base of the pseudobulb or on the lower nodes, two-rowed, ribbon-like or rarely inverted-lanceolate to narrowly elliptic, the base is generally broadly sheathed and encloses the pseudobulb, with nodes. The racemes have several or multiple flowers, and the colors are white, pure white, white-green, yellow-green, light yellow, light yellow-brown, yellow, red, blue, and purple.

Cultivation techniques. Fertilize.

It is not possible to do it without it, and it is even more difficult to apply more and repeat it. For example, if the new orchid is potted, the potting soil is too fat, and it often cannot survive, and even if it can survive, it rarely blooms. If there is too much fertilizer in summer, the autumn leaves are more vigorous, which often leads to poor flowering of the leaves in spring next year.

If there is too little autumn fertilizer, it will affect the formation of underground flower buds at the turn of autumn and winter. If there is too much nitrogen fertilizer and too much fertilizer on weekdays, the growth of leaves and flowers will be nutriently unbalanced, and the phenomenon of no flowering or less flowering will occur. Generally speaking, the leaf buds are newly emerging and can be applied several times with a small amount of light fertilizer.

The spring equinox, the autumn equinox and about 20 days after the flowers are falling, are more appropriate times. The best time to apply fertilizer is in the evening, and then water once in the early morning of the next day. Apply once every 2-3 weeks.

At the same time, spray Boshimai potassium dihydrogen phosphate once every 20 days to promote the flowering of pregnant buds. Fertilization depending on the color of the leaves, is a more appropriate method, the leaves are yellow and thin is a lack of fertilizer, should be top dressed, black and the leaf tip is scorched is too much fertilizer, should stop fertilization. Fertilizer must be rotten, can not be used without rotting, avoid using human feces.

Watering. Practice has proved that orchids are eight points dry, two points wet is the best, and the flowering period and the leaf bud stage should be watered less. During the rainy season, you should move back indoors or build a shelter to protect yourself from the rain.

In summer, it should be watered early in the morning or evening, not too much, and the amount of watering in autumn can be increased as appropriate. During the dry season, spray every evening. When spraying, it should be sprayed upward, so that the fog point is fine and even, so that the leaf surface is moist, the ground is moist, and the air humidity is increased.

Sometimes it is best to spray several times a day, and watering should be watered from the edge of the pot, not poured on the head, not at noon. Although watering in winter can be greatly reduced, but not without watering, pay attention not to let the potting soil dry out, winter is not early spring and watering causes the leaf sheath to be wet, to be moved indoors after drying, so as not to rot. In short, dry is watered, wet is stopped, appropriate dry for the principle.

It is better to use rainwater and spring water, and all kinds of water should be taken and stored in the tank first, so that the pollutants in the water can be precipitated, the water temperature is normal, and the chlorine in the tap water is exhausted, and then poured.

Illumination. Light is an important factor in the formation of flower buds. Although orchids love coolness, they rarely bloom if they are kept in a hidden place all year round.

Orchid artists have long discovered that the leaves of the Yin Orchid of the Mountain are long and the flowers are sparse, and the Yang Orchid of the Mountain is short and has many flowers. Therefore, when cultivating orchids, we must pay attention to the problem of light. In spring and summer, orchids are best shaded by reed curtains or placed in windows with ventilation facing east and south.

The orchid under the curtain should be repotted once every half month, so that the orchid receives light on all sides, which is conducive to the balanced growth of the plant. When autumn is cool, the potted orchid should be removed from the shade and let it bask in the sun for half a day in the morning, but be careful not to dry out in autumn. In cold weather, it is placed indoors under the south window for wintering, but it does not have to be too warm, and it is best to cover it with a plastic film cover to maintain the proper humidity of the leaves.

As for the prevention and control of pests and diseases, such as brown rust and white silk disease, use stone sulfur mixture**. If there is an ant nest, you can soak the pot in water to drive it away.

Hello, friends, orchids are in such a situation, it is caused by the lack of light, put it in a sunny place for maintenance, and then you can put a small amount of compound fertilizer.

The orchid is composed of 3 outer petals and 3 inner petals and 6 petals, the orchid is composed of 5 large petals, such as plum petals, lotus petals, narcissus petals, plain heart petals, and odd petals, the large petals above the stamen's pillar are called the main petals, and the two petals that are shorter on the upper side of the stamen's column are called the petals, and the petals below the stamen's column are particularly white.

Orchid petals refer to the tepals of the inner wheel, among the three petals of the orchid family, the middle petal is the lip petal, and the two petals on the side are still called petals. The petal refers to a round of petals in the middle of the orchid, which is composed of petals and lip petals, commonly known as the heart or petals.

The flowers of orchids have several petals.

The orchid consists of 3 outer petals and 3 inner petals with 6 petals。The orchid is composed of five large petals: plum petals, lotus petals, narcissus petals, plain heart petals, and odd petals. The large petals above the stamens are called the main petals, the two petals on the upper side of the stamens are called the petals, and the petals below the stamens are particularly white.

Orchid petal type classification.

1. Plum petals

The calyx is short and round, resembling the petals of plum blossoms, the rod petals are pocketed, and the lip petals are straight, hard and not rolled back. Songmei is the typical representative species of orange, and there are about 50 common species.

2. Lotus petals

The calyx is thick and broad, resembling lotus petals, the rod petals are not pocketed, resembling two half-open mussel shells, and the lip petals are wider than the other petals. According to its flower size, it can be divided into three types: small, medium and large. Zheng Tonghe and Gaihe are the representative species.

3. Narcissus petals

The calyx is narrower than the plum petal, the petal end is long and pointed, the rod petal has a slight pocket, and the lip petal is drooping and often postcurled. Narcissus petals are further divided into plum-shaped narcissus petals and lotus-shaped narcissus petals. Plum-shaped narcissus petals, the flower burns the calyx slightly like a plum petal, but the petals are longer. Lotus-shaped narcissus petals, large potatoes resemble lotus petals.

4. Plain heart valve

If there are no heterochromatic spots, patches, or markings on the lip flap, it is a plain heart valve. According to the color of the lip flap, it can be divided into green placenta, white placenta, yellow placenta, peach gill, and prickly hair, with green placenta as a treasure. The plain heart petals are divided into four categories: sepals and petals, which can be divided into four categories: grass, bamboo, lotus, and plum.

5. Odd petals

The lower edges of the secondary and petals are similar to those of the labial petals, and the surface is vesicular and densely bulging like a toad skin. In addition, the increase or decrease of calyxes and the increase of lip petals are all odd petals. There are three main categories: butterflies, side lobes and rod lobes.

Orchids bloom. The time of flowering of the orchid is not fixed, as long as it is well maintained, it can bloom multiple times a year.

For example, spring orchids generally bloom in February and March; Nine-headed orchids generally bloom in March-April; Jianlan generally blooms from July to October; The orchid generally blooms in June-July; It usually blooms in November during the winter and lasts until February.
