How should phalaenopsis control temperature, humidity and light? How should I repot?

Phalaenopsis usually blooms in winter and is a relatively expensive Spring Festival flower. Phalaenopsis orchids are usually grown with water moss. The newly bought phalaenopsis does not prune the roots, and it is okay to plant it with the original plastic nutrition bowl.

This state of matter can last for about two years. By about 2 years, the roots will grow luxuriantly and need plenty of growth space and nutrients, so it is necessary to change the new temperament at this time.

The roots of phalaenopsis are mostly famine, mainly regenerating plants that can attach to trees and absorb nutrients and water independently. Therefore, the temperament we use can only play a fixed role, so that the breathability becomes loose must be good. Generally, the temperament of phalaenopsis is moss or pine bark, which can be changed every 1 2 years.

Phalaenopsis should be repotted after flowering.

Phalaenopsis prefers an environment with high air humidity. In the south, the humidity of the air is relatively high, and the changed temperament can be used as pine bark. Pine bark is more breathable, less conservative, and just right for the humid environment of the south.

The air in the northern region is relatively dry, and the temperament can be cultivated with moss. The air permeability of the water clip is relatively good and the conservatism is good.

When repotting, the long roots, rotten roots, and broken roots of phalaenopsis should be repaired to prevent the substrate from rotting after encountering water. After repairing the roots, carbendazim or zinc ginseng should be soaked to prevent wound infection. Take it out and dry it before putting it in a basin.

The pot is one size larger than the original, but not too large. First, soak the temperament in clean water, then squeeze out the excess water. Insert medium in the middle of the roots of the phalaenopsis and put it in a pot so that the roots are not squeezed together.

To grow phalaenopsis at home, the temperature is best between 15 and 25 degrees, which is the most suitable temperature for its growth and flowering. Spending more time in autumn and winter can help with flowering. Also, when there are flower buds, spraying potassium dihydrogen phosphate helps to open all the flower buds.

In winter, it is necessary to keep out the cold and freeze, and it must be kept warm when it is lower than 5 degrees. When repotting, protect the roots as much as possible, knock off the existing aging moss, cut off the old roots and long roots, and wrap the outside with new moss. A well-grown phalaenopsis can also be repotted twice a year, and if the plant is found to be weak or rotten, it is necessary to change the pot in time.

Top dressing should be carried out once a month during the growing season, and it is absolutely not necessary to use high-concentration fertilizers, and watering with water works well. If foliar sprays and extra-root top dressing are used alternately, fertilizer utilization efficiency can be improved and fertilizer loss can be prevented. Fertilization should not be applied when the temperature is above 32 or below 15.

No fertilization. Apply 1 time per month 2000 times 1:1:1 on the roots from spring to July

1. Nitrogen, phosphorus and potassium compound fertilizer, apply liquid fertilizer twice in August, and spray foliar fertilizer with potassium dihydrogen phosphate liquid after September

Phalaenopsis prefers a shady environment and does not leave it in the sun, but also needs proper sunlight. Don't hurt the roots of the phalaenopsis when changing pots, you can put some gravel at the bottom of the new pot, put some moss and put the phalaenopsis in it.

The temperature and light should be carefully controlled, and an upper limit should not be too high or too low, and you only need to pay attention to the relevant matters and follow the relevant steps when changing pots.

It grows well in the environment of 15-25, but it is easy to produce diseases in the high temperature and high humidity environment, and cooling measures need to be taken to reduce the ambient humidity in the high temperature season. When repotting, protect the root system as much as possible, and the original aging moss should be removed, and the old roots and overly long roots should be cut off, and the outside should be wrapped with new moss. Well-growing phalaenopsis orchids can also be repotted twice a year, and if the plant is found to be weakened or the substrate is rotten, it needs to be repotted in time.

Cultivation of Phalaenopsis to increase humidity method:

1. Place a water cup: If you want to humidify the phalaenopsis in the process of maintaining the phalaenopsis, you can achieve it by placing the water cup, choose a disposable water cup or a water basin with a larger caliber, pour water into it, and then place it in the growth environment of the phalaenopsis to improve the humidity of the phalaenopsis growth environment through water evaporation. Slag plum.

2. Spraying water: If you want to humidify phalaenopsis in the process of maintaining phalaenopsis orchids, you can also spray water. First of all, you need to choose a watering can with a thin spout, then pour water into it, and spray the appropriate amount of water around the pot when the environment where the phalaenopsis grows dry, or spray water on the plants to increase the humidity of the environment.

3. Watering water: If you want to humidify Phalaenopsis in the process of maintaining Phalaenopsis, you can also achieve it by watering water, that is, to improve the humidity of the environment in the process of watering Phalaenopsis. At the same time, when watering Phalaenopsis orchid, it is necessary to observe the dryness of the soil, choose when the soil is relatively dry, and provide water for the plants to maintain the appropriate humidity of the environment.

4. Water source selection: When humidifying phalaenopsis, it is necessary to pay attention to the selection of water source, and it is best to choose river water or well water with rich trace element content for humidification treatment to help the healthy growth of plants. At the same time, it is necessary to reduce the use of tap water when choosing the water source, so as not to prevent the chlorine in the tap water from being unfavorable to the growth of plants and affecting the growth of plants.

Phalaenopsis is a perennial evergreen herb of the orchid family, an aerial orchid species native to tropical Asia, and a large family of tropical orchids; Among them, Taiwan produces the most. It grows in forests along the coast of rivers in tropical hot and humid areas, and grows on large trees. It prefers a warm, humid and well-ventilated environment, and is more shade-tolerant.

Its stems are relatively short, the leaves are large, the flower stems are one to several, arched, the flower diameter varies from 6-12 cm, butterfly-shaped, flowering in spring, the flowering period can be as long as 50-60 days. Potting soil cultivation should be aerated and water retained, and drainage should be good, generally using snake sawdust, water moss, charcoal, broken bricks, etc. Generally, change the pot after spring flowering, and renew the cultivation materials in the pot, otherwise it is easy to accumulate dirt and surface moss, and it is easy to breed diseases and pests.

The suitable temperature for growth is 15-30, the temperature is kept at about 27 during the day, and the temperature is kept at about 18 at night. When the summer temperature exceeds 35, growth and development are inhibited. The demand for light is not high, as long as there is scattered light, it can be satisfied, it is not resistant to direct sunlight, and it needs to be shaded about 70% in summer, and 30-50% in other periods, except in winter.

The growing season needs sufficient water, in the vigorous growth period to keep the substrate in the pot moist, not dry, in the winter when the temperature is low can be drier, because Phalaenopsis is a fleshy root, so watering should be done rather dry than wet. Phalaenopsis has high air humidity requirements, generally between 75-90%, and less than 50% plant growth is inhibited. When the air is dry in summer or season, spray water on the ground or on the leaf surface to increase air humidity.

Phalaenopsis is more fertilizing, and fertilizer is applied every two weeks during the growing season, mainly nitrogen in the vegetative growth period, and phosphorus and potassium fertilizer in the reproductive growth period. With proper management, pests and diseases generally do not occur.

Prefer high temperature, high humidity, ventilated environment; It is not resistant to waterlogging, semi-shady environment, avoid direct sunlight, and the overwintering temperature is not less than 15 degrees. Phalaenopsis is a tropical high-temperature orchid, and the suitable growth temperature is 20-30 degrees Celsius. If it is below 15 degrees, it will enter dormancy, and below 10 degrees it is easy to die.

However, high temperatures above 35 degrees affect growth and are susceptible to disease. Flowering takes a month of low temperatures of 15-18 degrees Celsius to promote flower bud differentiation, after which peduncle germination is stunted if the low temperature continues.

Phalaenopsis prefers a humid and ventilated environment. The air is required to maintain humidity of 60 80 often, and to keep the air circulation is best to have a breeze blowing, the pot can not accumulate too much water, if the root is surrounded by liquid water for 6-8 hours, it is easy to rot the roots, so aeration is the key to raising a good Phalaenopsis orchid, the material needs to be crisp and breathable, the root growth is strong. Avoid hot and dry winds.

Winter planting in the north should not be placed on a radiator or directly in front of an air conditioner.

Likes high temperature and high humidity. It is mastered at around 27 degrees during the day and 18 degrees at night. The maximum is not higher than 32 degrees. It is best to master 13-15 degrees when flowering. Humidity of 50%-80% is preferred.

A Tao teaches novices to raise phalaenopsis series (4): raising a good Phalaenopsis thermohygrometer is a good helper.

1. Temperature, how to raise Phalaenopsis in winter, the hard condition is to keep warm the key to Qingzao, if the temperature in winter does not reach 15 or above, then it is a big blow to Phalaenopsis and even death, so Phalaenopsis meets the temperature in winter This condition is the primary condition for Phalaenopsis wintering.

At a temperature of 10-15 degrees, Phalaenopsis enters a semi-dormant state and grows slowly. The temperature is dormant below 10 degrees, the bottom leaves begin to degenerate and turn yellow, the leaves below 7 degrees begin to appear cold damage, the cold damage below 5 degrees is aggravated, the cells are dehydrated and lose their metabolic ability, and the indoor cultivation of Phalaenopsis orchid in winter, if the average indoor temperature is lower than 12 degrees, and the minimum temperature is lower than 7 degrees, there is no heating facility to use, it will not be able to overwinter normally. Poor destruction.

2. Watering, Phalaenopsis is not resistant to low temperatures, if the temperature cannot be met, try to control the water in winter. In winter, when the temperature is below 15 degrees, it is necessary to control the water, keep the water moss dry, and spray less water mist on the leaf surface at noon on a sunny day when the temperature is high.

3. Sunshine, although Phalaenopsis likes semi-shaded environments, the longer the sunlight shines in winter, the better. Strong light shortens the flowering period during flowering, while low light prolongs the flowering period.

After the phalaenopsis entered the room, the light was restricted, and the pots had to be manually moved to adjust it. Under normal circumstances, it should be placed indoors in a sunny place during the day to let it shine into the sunlight and maintain its original color. Before flowering, it should also be placed under fluorescent lamps for indoor supplemental light at night.

Because the two rows of leaves of Phalaenopsis are opposite, if the light is in one position for a long time, the leaf growth will be uneven, affecting the ornamental effect, for this reason, the direction of the leaves should be paid attention to when adjusting the light, and the sunny side should be changed every 10 days or so. There are two ways to place the pot indoors, one is to place the leaves parallel to the sunny window, and the other is to put the leaves perpendicular to the sunny window, the latter effect is better than the previous one.

4. Fertilizer, Phalaenopsis winter flower buds have appeared, people can't help but want to fertilize, but winter fertilization is not appropriate, you must wait until spring to start fertilization, or new roots have begun to grow orchid plants can be fertilized. If it is still in the growth telogen phase, it should not be fertilized.

1. Temperature: It likes a warm, humid and ventilated environment, and the suitable temperature for growth is 18 28 degrees.

2. Lighting: In spring and autumn, it is ideal to accompany the bright scattered light in the window, avoid direct sunlight in summer, and place it near the window facing south in winter to receive more wheel light.

3. Watering: Use broken fern roots, bark, etc. as substrates, and during the growth period, water is generally poured once a day around the leaves to humidify, if the moss cracks are used as the main base material, generally water around once every other day to humidify, pay attention to the watering and humidification do not water the roots when watering and humidifying. No matter what substrate is used, the growing period should wait for the surface of the substrate to dry before watering, dry and watered, can not accumulate water, in fact, dry and thoroughly watered is only relative, different varieties in different regions.

4. Fertilization: Nitrogen fertilizer is the main method for young plants, and it is increased after the seedlings and flowers are gone.

5. Phosphorus and potassium fertilizers should be applied frequently during the growth period, and can also be regularly applied on the pot surface.

6. Apply special slow-acting granular fertilizer, and the fertilizer effect can slowly penetrate with watering.

7. Do not fertilize the roots, buds and flowering periods, otherwise it is easy to cause bud drop.

8. Reproduction: Generally propagated by ramification. Phalaenopsis is a single-stemmed orchid, but sometimes small seedlings grow from the base of the plant, when the seedlings grow to 3 or 4 pieces, they can be separated from the base of the old plant, and are planted in small pots with moss to maintain, and the branches are mostly carried out before the germination of new shoots or after flowering, at this time the nutrients are concentrated and the disease resistance is strong.
