How to raise orchids in the northern region, and are orchids suitable for raising in the north?

1) Choose the size of the pot, so that the root can be completely comfortable in the pot. Generally, tile pots are chosen. If it is beautiful, you can put a colored glazed porcelain basin on the outside of the tile pot.

It is best to use orchid mud for potting soil. It can also be mixed with 6 parts of humus or peat, 3 parts of sandy soil, 1 part of cake fertilizer, or 5 parts of humus, 3 parts of compost and 2 parts of coarse sand. Each material is crushed and sieved before being thoroughly mixed to make it have a consistent density and disinfected before use.

When potting, the bottom of the pot is first padded with furnace ash and other materials to facilitate drainage and aeration, and then the orchid plants are planted.

2) Watering in moderation. Orchids are fleshy roots. Excessive watering is easy to rot roots, and water every 1 2 days in spring and autumn; The temperature is high in summer, and it is the peak period of orchid growth, it is usually advisable to water once in the early morning and evening, and avoid watering at noon. The temperature is low in winter, most orchids enter the dormant period, at this time to control watering, you can water every 5 7 days, in the winter flowering of the orchid and Han orchid should be appropriately more.

During dry seasons and hot summers, the foliage should be sprayed with water frequently and water should be sprinkled on the ground around the pot to increase air humidity. Watering orchids should be poured slowly from the edge of the pot, not poured on the head, and pay attention to prevent water from splashing on the leaves, otherwise it is easy to appear black scorched spots, which will affect the ornamental value.

3) Pay attention to the skillful application of thin fertilizer, and avoid the application of thick fertilizer. Generally, newly planted orchid plants should not be fertilized in the first year, and fertilization should be started after Qingming in the second year, until the beginning of autumn, and 1 2 times a month can be applied to fully rotted thin cake fertilizer water. Before fertilization, the water should be controlled for 1 2 days, and the potting soil should be slightly dry before application.

Water the next morning after application to prevent unclean substances in the fertilizer solution from contaminating the root system and causing damage to the roots. When applying liquid fertilizer, care should be taken to avoid staining the leaves. After several years of cultivation, nitrogen fertilizer was mainly applied to the orchid plants that had reached flowering age to promote the germination and rapid growth of new shoots, and phosphorus and potassium fertilizers were mainly applied in the later stage, which was conducive to the enlargement of pseudobulbs, wide and thick leaves, and provided sufficient nutrients for flower bud differentiation.

Specifically, before the differentiation of flower buds in autumn every year, it is advisable to apply liquid fertilizer based on phosphorus and potassium fertilizer twice in a row, wash the leaves with water in the evening of sunny days during the bud pregnancy period, and then spray the potassium dihydrogen phosphate solution on the leaf surface and leaf back with a small sprayer after drying. At this time, you can also apply ash water to the roots. About 20 days after flowering, apply two liquid fertilizers or compound fertilizers based on nitrogen fertilizer to promote plant growth.

Do not fertilize on rainy days, and stop fertilizing during dormant periods in winter.

The lighting should be appropriate. In the north, April and early May, there is plenty of sunshine before 9 a.m. After mid-May, shade is required, and it needs to be moved to a cool and ventilated place for cultivation.

Chunlan and Xialan need more sunlight. After the autumn coolness, all kinds of orchids should be exposed to more sunlight to enhance the vitality of orchids and promote the differentiation of flower buds. In winter, move indoors to a half-light place.

The black orchid and cold orchid that bloom in winter should be placed indoors in a sunny place.

In order to prevent and control black spot disease, spray 500 600 times rice vinegar solution on the back of the leaves and around the orchid plant every 5 7 days in the evening, which can make the orchid plant strong and the leaves black and shiny.

Dumen Yilan Ji is the experience of planting orchids in Beijing, and the watering method he proposed is treated separately according to the 24 solar terms in a year

1) Beginning of spring, rain: the spring orchid has flowered, the soil should not be too dry, slightly moistened along the edge of the pot: if the autumn orchid pot is not dry to the bottom, do not water.

2) Sting: When the spring orchid basin is dry to the orchid basin (above and below), you can cry water, but not too much; Ibid. Qiulan.

3) Spring equinox: Chunlan has bloomed, avoid moisture, when the pot is half dry, you can moisten the water.

4) Qingming and valley rain: Do not make the potting soil too dry, and moisten it once every 5 days.

5) Lixia: When the orchid begins to go out of the house, it is advisable to water it thoroughly.

6) Xiaoman: The potting soil should not be too dry and too wet, the spots on the leaves are too wet, and the tips of the new shoots are too dry. Water 1 liter every 4 days to make the potting soil from the bottom up.

2 3 Moist is advisable.

7) Miscanthus species: Beijing is dry, and it is better to pay attention not to be too dry and too wet.

8) Summer solstice: Do not overshoot the potting soil. In case of heavy rain, you can only endure it for one day, and in case of continuous rain, you must move the basin to a ventilated place.

9) Xiaoxiao: At this time, the air is too humid, not dry but too wet, the basin should be placed in a ventilated place; If it is hot and rainy, water 1 liter every 2 days. Heavy rain or heavy wetness once, must be dried to the potting soil 2 3, otherwise it is not suitable to water again.

10) Heat: The potting soil is easy to dry to the end, and it should be noted that heavy rain or heavy humidity should only be used once a day.

11) Beginning of autumn: The orchid needs water at this time, and it must be watered 2 liters every 3 days, and it is advisable to shelter from the wind a little.

12) Heat: watered once every 5 days, except for the rain in the morning, it can be exposed to rain and dew.

13) White dew: Autumn orchids must be watered more frequently than spring orchids, but they must be dried after being wet before they can be watered again.

14) Autumn equinox: If the autumn orchid has already flowered, the watering should be slightly less; If the flowers are not produced, the watering should be slightly increased.

15) Cold dew: Autumn orchid should be watered thoroughly, while spring orchid should not be penetrated and moistened.

16) Frost Long: Lan Yi enters the house, the watering time is changed to the middle of the day, and the water must be exposed to the sun for 1-2 hours in the middle of the day.

17) Beginning of winter: only moisten water, about half a liter every 5 days.

18) Light snow: the flower room is not warm; It should not be too wet, if it is too wet, it can cause rotten roots, scarred leaves and even wilting. If the potting soil does not dry to the bottom, only moisten the soil skin slightly.

19) Heavy snow: Autumn orchid does not need water, and spring orchid should be slightly moist.

20) Winter solstice: not suitable for irrigation.

21) Xiaohan: avoid watering.

22) Great cold: Qiulan still does not need water, and Chunlan can be slightly moisturized.

Watering orchids is also very important. In June-July, when the orchid leaf buds are about centimeters long, 1-2 times of thin and well-rotted liquid fertilizer can be applied (chemical fertilizer is not suitable for use). By August-September, apply another 1-2 times of decomposed thin liquid fertilizer.

Orchids of plain heart can be applied 1-2 times of plant ash leach, and the effect is very good. Fertilization is best done in the evening, and water again the next morning.

Orchid is a kind of tenacious flower, native in the winter without severe cold, summer without heat, the most suitable growth temperature is 10-30, in China's Jiangsu, Zhejiang, Yunnan, Guizhou, Guangzhou, Sichuan region distribution more, the northern region to raise a good orchid, focus on overcoming the following two problems:

1. Prevention of low-temperature frostbite: orchids like a warm and humid environment, poor resistance to low temperatures, most of the orchids below 10 are about to enter a dormant state, below 0, except for some orchids can survive for a short time, most of the orchids will be frostbitten, so the first problem to pay attention to in raising orchids in the north is to prevent low-temperature frostbite.

2. The air humidity in the north is too low: orchids like the external environment where the air humidity is 60-70%, and the vast northern region is at a more obvious disadvantage in this regard, too low humidity is easy to cause orchid leaves to crack, dull, orchid leaf buds and flower buds are not easy to survive and other hazards, so the northern orchid should pay attention to regulating air humidity.

3. Difficulties in vernalization: Another thorny problem encountered in raising orchids in the north is the selection of the growth environment of orchids that need vernalization. The winter temperature in the southern region is just suitable for the vernalization of orchids, while the winter orchids in the north have to be moved indoors or in the greenhouse, and the temperature is not suitable for vernalization.

Orchids do not undergo vernalization, it is difficult to bloom or the opening is not good, therefore, the selection of winter vernalization environment is also a major problem that needs to be paid attention to in northern orchid cultivation.

It is more difficult to breed orchids in the north, because the weather in the north is cold and frozen all year round, which is not conducive to the growth of orchids, but it does not mean that the north can not breed orchid nuclei in early spring, only to change the finch is to be more careful when breeding, only careful breeding can be raised, so what is the method of breeding orchids in the north? The following is a detailed introduction to its breeding method.

Methods of cultivating orchids in the north:

1. Choose a good pot and culture soil.

Generally, families raise orchids, and the choice of pots is still better than mud pots. If you want to add beauty to the decorative effect, you can put a glazed porcelain basin on the outside of the clay pot. The size of the pot should be such that the root can be completely comfortable in the pot.

It is best to use orchid mud for potting soil. It can also be modulated by itself. It can be mixed with 6 parts of humus or peat, 3 parts of sandy soil, 1 part of cake fertilizer, or 5 parts of humus, 3 parts of compost soil and 2 parts of coarse sand.

For potting methods, please refer to: common sense and cultivation techniques for orchid purchase.

Second, watering should be appropriate.

Watering orchids is a regular task and an important part of the success of orchid cultivation. The potting soil of orchids should be kept moist frequently, but avoid excessive water content. In cultivation, the amount of watering should be decided according to the different seasons and different stages of orchid growth.

Generally from spring, with the rise of temperature, orchids turn into a vigorous growth period, should gradually increase the amount of watering, every l 2 days watering 1 time; The temperature is high in summer, and it is the peak period for orchid growth, so it is usually advisable to water once in the early morning and once in the evening, and do not water at noon. When the rainy season comes, it is necessary to flexibly grasp the amount of watering according to the amount of rain and the humidity of the potting soil, and avoid root rot caused by water accumulation in the potting soil; At the end of autumn, when the temperature begins to drop, the amount of watering should be gradually reduced, and it can be watered once every 2 3 days; The temperature is low in winter, most of the orchids enter the dormant period, at this time to control the watering, can be watered every 5 7 days 1 water, but the winter flowering Mo Lan and Han Orchid watering should be appropriately more.

The northern region is generally dry, the soil is alkaline, and the temperature is generally low in winter, even if there is heating indoors, it will be very dry and difficult to ventilate. Therefore, it is suitable for breeding orchid varieties that are more cold-tolerant, adaptable, and not very demanding on soil. To sum up, the northern region can raise two kinds of orchids, Jianlan and Molan, which are adaptable and relatively cold-resistant, and can be as low as minus two degrees, but it is necessary to pay attention to controlling moisture.

Watering: To raise orchids in the north, you should adjust the way according to the change of seasons, and the same is true for watering. In spring, orchids enter the growing season as the temperature rises, and they can be watered once a day or two.

In summer, when orchids are at their peak, they can be watered in the morning or evening. During the rainy season, it is necessary to control the amount of watering according to the humidity of the potting soil. In autumn, when the temperature has already begun to drop, you can reduce the frequency of watering, you can water once every two or three days.

In winter, the temperature is very low, and you can water it once every five to seven days, but Jianlan and Molan are more hardy and can grow in winter, so you can give a little more water.

Light: Orchids generally prefer a cool environment and do not like direct sunlight. Therefore, in April and May, you can let the orchids see the sun before 9 a.m., and after mid-May, the orchids should be kept in a cool and ventilated place.

In winter, orchids can be maintained in a sunny place, so that the plants receive more light, which can promote the differentiation of flower buds.

Fertilization: Fertilizing orchids can not be applied with thick fertilizer, only with thin fertilizer. Newly planted orchids can be planted without fertilization in the first year, and fertilization will be started after Qingming in the second year, until the beginning of autumn.

Northern orchids can be fertilized once or twice a month with rotten pancake fertilizer water, each fertilizer needs to be controlled for two days before fertilization, and then fertilized after the potting soil is somewhat dry. Water the next morning after fertilization.

Orchids are relatively easy to raise.

Precautions for northerners to raise orchids:

First, it is necessary to follow its nature and create a small environment suitable for the growth of orchids. Lamben was born in the lush forest valley, beside the roots and grasses, the breeze is blowing, the climate is humid, there is no scorching sun in summer, there is little frost and snow in winter, and the rain and dew are moist and prosperous. Obviously, Lan.

The ecological environment of the origin of the flower is very different from the atmosphere of dry spring and autumn, hot and humid summer, and dry and cold winter on the balcony in the north.

This requires northern orchid friends to focus on the ecological habits of orchids and strive to create a small environment suitable for their growth. Most of the balconies in the north.

It is a closed aluminum alloy glass balcony that can be pushed and pulled freely, which is ideal for ventilation, but the air is dry and the humidity is too low.

Therefore, it is particularly important to solve the problem of low air humidity. My practice is to make three layers of blue shelves out of hollow stainless steel, each layer.

The bottom is equipped with a glass sink, and the orchids are placed on it, ventilated on all sides, which not only increases the air humidity, but also prevents heat stroke and cools down, and then configures the ultrasonic humidifier to create a small environment suitable for the growth of orchids.

Second, it is necessary to adapt measures to local conditions and prepare breathable, draining, and nutrient-rich planting materials. Good planting is half the battle. Select the plant.

Be cautious. The soil in the north is generally alkaline, and the choice of planting material is very important. I think a good planting material must be breathable

There are three conditions of draining water and nutrition. Practice has proved that the best combination of traditional and modern orchid planting material is granular planting material and sifting.

Orchid puree mixed with orchid planting works best. Lanyou can start from the actual situation and prepare the mixed planting material by yourself. I used sieved humus.

Soil, grub feces, weathered stone three-in-one planting material, raising orchid trees, buds and seedlings, the effect is good.

Third, choose the water and water moderately. It is best to use rainwater for watering orchids in the north, and you can reserve more in the rainy season for daily use.

For this purpose, as long as the tap water is not alkaline, it can be directly used to water the orchid, otherwise it must be improved and reused. "It's easy to raise orchids, water.

Water for three years. "You can't be sloppy when it comes to watering. According to the planting situation, in line with the principle of seeing dry and wet, spirit.

Live mastery. Don't stick to watering once a few days as the book says, but water as needed.

Fourth, it is necessary to give priority to prevention and combine prevention with prevention. Raising orchids should have a sense of distress, daily management should be persistent, and regular orchid farms should be maintained.

Ground and orchids are sterilized to take precautions and strive to eliminate pests and diseases in the bud. Don't storm or chill.

In a hurry.
