The orchid was watered on the first day, and it rained for a few days on the second day, did the hea

It's fine. 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.

This doesn't matter, but be protected from the rain.

Generally, orchids are watered once every 2-3 days from March to April, or a small amount once a day; Watering once a day from May to June; From July to September, fully water once a day in the evening; From October to November, water once a day; From December to March of the following year, water once every 4-5 days. If you want to water a large amount of water at one time in winter, you can water it on a rainy day to prevent frost damage; Because it does not water on rainy days, it freezes into ice.

Orchid category: 1. Spring orchid.

It blooms in February and March in early spring, and is commonly known as grass orchid or mountain orchid. The leaves are clustered, narrowly linear, 20-25 cm long, with rough margins. The flowers are mostly yellow-green, one stem and one flower, and the fragrance is strong.

2. Huilan. It usually blooms in April and May, and is commonly known as Xia Lan, and there are also those called Jiujie Orchid. The leaves are narrow, 25 cm. In early summer, the flower stem is extracted, there are seven or eight flowers on one stem, more than ten flowers, the color is light yellow, the lip petal is green and white, and there are purple-red spots, and the flowers are fragrant.

3, Jianlan. Growing in Fujian, commonly known as autumn orchids, it mostly blooms in autumn. The leaves are broadly linear, 30-60 cm long, mostly erect, with smooth margins and darker leaf color. There are seven or eight flowers on one flower stem. The flowers are yellow-green to pale yellowish-brown, with dark purple-red stripes, and the aroma is very strong.

4. Hanlan, Molan.

Blooms in winter. The leaves of the orchid are narrow and erect: the flower stems are thin, the flowers vary from 5 to 10, the petals are narrow, and the flower colors are more, including purple, green, yellow, white, peach, and red; Flowering period: winter to early spring.

Mellan, also known as primrose, blooms around the Spring Festival, the leaves are 50 100 cm long, up to 3 cm wide, the leaf margin is smooth, the apex is pointed, erect: the flower stem is about 60 cm high, with 5 10 flowers, the flower color is dark, and there are many purple-brown striped spots.

Orchids grow at different rates in different seasons and require different amounts of water. Therefore, the frequency of watering will also vary.

1. Spring: At this time, the climate is warm, the plant grows faster, and the water demand is larger, so it needs to be watered every 2-3 days to replenish the water needed for its growth.

2. Summer: At this time, the temperature is very high, and the water in the plants and planting materials will evaporate quickly. Therefore, it needs to be watered 1-2 times a day to provide the necessary moisture and prevent it from running out of water.

3. Autumn: At this time, the climate is relatively humid and the temperature is suitable, so you can water it every 3-4 days. In this way, it can meet the needs of orchid growth.

4. Winter: It is relatively cold at this time, orchids grow very slowly, and even enter a dormant state, and the water demand is very low. So you just need to water it every 10-15 days.

When watering it, if you have experience, you can't control the number of waterings, and it is best to water it strictly according to the dryness and humidity of the soil. But for novices, you can follow the following method of watering, in spring and autumn, it should be done once every 2-3 days. Water 1-2 times a day in the summer, as the water in the soil will evaporate quickly.

It is prudent to water it in winter, you can water it once every 5-7 days.

Orchid. 2. Time.

When the weather is hotter, it is necessary to avoid watering it at noon, and you can do it in the morning. However, if the temperature is relatively low, it should be avoided in the morning and evening, and it is best to water when the temperature is slightly warmer. Also, the water temperature of watering should not be too high or too low, so as not to cause harm to the root system of the plant.

Orchid. Precautions.

Pay attention to ventilation after watering, because sometimes the maintenance environment is poorly ventilated, it will affect the evaporation and absorption of water.

Do not water half of the watering, you should water the potatoes in the pot thoroughly, it cannot be said that only the surface of the soil is wet, and the soil inside is still dry.

The timing of watering orchid plants.

Lan "likes to moisten but is afraid of moisture, likes to be dry and afraid of dryness", this ancient saying is very scientific. "Wet", "moist", "dry", "dry" is different degrees, too wet is wet, "wet" is too much water, will suffocate and rot the root to die; Too dry is dry, "dry" is too lack of water, which will make the orchid plant wilt, growth frustrated, and even dry to death; The "dry" and "moist" are moderate moisture, which is the favorite state of orchid growth. In order to understand the key issue of "drying" and "moistening," we must carefully observe and experience in practice, and gradually accumulate experience in order to truly grasp it.

Generally speaking, when the planting material on the pot surface is dry but not dry, and the hole at the bottom of the pot is moist but not wet, it is the best time to water the orchid plant. There is no need to wait for the potting soil to dry completely before watering, otherwise it will have a negative impact on the growth and development of orchids.

It can be watered every 2 to 3 days in spring, once a day in summer, every 3 to 5 days in autumn, reduced in late autumn, and once every 7 to 10 days in winter.

There is no fixed number of days to water the flowers, and the frequency of watering is affected by many factors, generally following the principle of seeing dry and wet, and watering thoroughly when dry. The climate varies significantly throughout the year, so the frequency of watering also changes.

Orchids are watered once a few days, and there is no fixed interval, generally according to the water shortage of orchid plants and the dry and wet conditions of the soil.

Different seasons have different climates, watering intervals are also different, spring growth rate is fast, water is needed, can be watered every 2 to 3 days, high temperature in summer, water evaporation is fast, you can water once a day, autumn can be watered every 3 to 5 days, later late autumn to reduce watering, winter can be watered once in 7 to 10 days.

When watering orchids, you must not water half of the water for a long time, otherwise the upper surface of the soil is relatively moist, and the lower end is still in a dry state, which still cannot play the role of replenishing water. When watering, be sure to water thoroughly at one time so that a little water can flow out from the bottom of the pot.

The specific watering frequency also needs to consider the drainage of the planting material, if the drainage is good, you can increase the watering frequency to avoid water shortage.

In rainy weather, when the humidity is high, you can pause watering first. If the orchid is drenched by heavy rain, drain it in time to avoid water accumulation in the roots.

Orchid watering should be carried out in different seasons, and in the spring when everything is recovering, water once a day before 9 o'clock in the morning, and avoid watering at night; In the dry and hot summer, water once a day in the morning and evening to strengthen indoor ventilation; In the rainy autumn, watering is sufficient every two days, and in winter it is generally watered according to soil moisture.

Orchids are generally watered once a day before nine o'clock in the morning in spring, do not water the plants at night or in the early morning, because the air is not circulated at night, and the water cannot be completely dispersed, which is easy to cause waterlogging of the root system of the plant, causing root rot and causing the death of the orchid.

In summer, the weather is dry and hot, and the water loss of plants is fast, so increase the number of watering, watering once a day in the morning and evening, watering thoroughly, so that the soil of the plant has been in a humid state, and to strengthen the circulation of indoor air, often spray the plant with water mist, so that the surface of its stems and leaves is moist.

Autumn is the rainy season, the temperature is high and low, the temperature difference of the day fluctuates greatly, the air is very humid, so watering every two days can be, if you encounter continuous rain, you can stop watering, to ensure that the soil drainage is normal, to avoid root waterlogging.

The air in winter is very dry and the temperature is low, so the orchids are watered once a few days, and the orchids are generally watered once a month in winter to keep the soil slightly moist; The root absorption capacity of the plant is weak in winter, and if it is watered more, it will cause its root system to accumulate and rot, and in serious cases, it will cause the plant to wilt and die.
