The cultivation method and precautions of Rieger Begonia should be suitable for growth and development temperature

Rieger begonia is an herb of the family Begonia. Rieger crabapple is plump and rarely reddish brown. The flower shape is diverse, mostly double, the flower color is rich, and the flowering period is long, which can last from December to April. Next, let's talk about the breeding methods and matters needing attention of Rieger Begonia.

Culture methods of Rieger Begonia:

1. Temperature: the optimum temperature for growth and development of Rieger Begonia is 18 ℃ ~ 22 ℃. The focus of family care is to keep warm in winter, and the minimum temperature should not be lower than 15 ℃. As the winter Rieger crabapple is still in the growth and flowering period, it should be placed indoors facing south and sunny places, such as indoor windowsill and so on. But be careful not to get too close to the heater, so as not to burn the branches and leaves, and when there is a high temperature lasting more than 28 ℃ in summer, cooling measures should be taken, such as putting it in an air-conditioned room or shading at noon.

2. Watering: the basin soil should be kept moist, not dry and too wet; too dry will lead to water loss and wilting, and in serious cases, the whole plant will die; the basin soil is too wet, and the water fills the soil void, resulting in serious anoxia, which affects root respiration and death; too wet basin soil is also easy to provide opportunities for the infection of fungal and bacterial diseases, thus affecting the ornamental value of Rieger Begonia.

3. Plastic pruning: during the growth period, coring should be carried out to promote the plant to germinate lateral branches in order to achieve plump plant type, and the excess buds should be removed in time so as not to cause a large amount of nutrient consumption and affect the development of other flowers.

4. Diseases and insect pests: ginger juice squeezed with water and sprayed at the proportion of 1:25 can control soft rot and other pathogenic spore germination. # p# subtitle # e #

Points for attention in the culture of Rieger Begonia:

Application of fertilizer: Rieger Begonia mainly uses nitrogen fertilizer to promote its growth and development. With the growth of the plant, the amount of nitrogen fertilizer should be reduced, the content of phosphorus and potassium fertilizer should be gradually increased, and the amount of fertilizer should be increased before flowering. Foliar fertilizer can also be sprayed appropriately, the concentration of foliar fertilizer should not be too high, controlled between 1% and 2%, the spray should be uniform, and both sides of the leaf should be sprayed. Rieger begonia is sensitive to nutrient deficiency or excess, so fertilizer should be applied thinly and compound fertilizer at the ratio of 15:5:15 or 20:10:20 can be used to maintain the PH value of the solution between 5.0 and 6.0. According to the nitrogen content of dissolved liquid fertilizer, the concentration of nitrogen applied once a week is 250ppm and 300ppm, and the concentration of nitrogen is 100~200PM three or four times a week or every day. At the same time, Rieger crabapple special fertilizer can also be selected.

Watering points: usually watering Rieger crabapple depends on climatic conditions, usually evaporates quickly in summer, water demand is relatively more, watering should be in the morning or evening, watering times depends on the wetness of the basin soil. Winter watering as far as possible in a sunny day at noon, the water temperature should be close to the indoor air temperature, so as not to cause root stimulation and death because the water temperature is too low. It is best to use a humidifier to increase air humidity, or you can use a sprayer to spray fine mist on the leaves. Just see the leaves are wet, but do not spray water mist on the flowers.

Pruning essentials:

1. During the growth period, Rieger Begonia should be coring to promote the plant to germinate lateral branches in order to achieve plump plant type, and the excess buds should be removed in time so as not to cause a large amount of nutrient consumption and affect the development of other flowers.

2. After the cool autumn, Rieger Begonia begins to sprout new branches from the base. When it grows to a certain height, the old branch is cut off from the base with a sharp knife, and the amount of water is increased to promote the growth of Rieger Begonia. When the new branches are basically shaped, 3 new branches are retained in each pot, and the rest are all cut off to concentrate nutrients and make Rieger Begonia take shape as soon as possible.

Pot soil replacement: Rieger Begonia can not be changed in the first two years because the purchased pot soil meets the requirements.

Second, the culture method of Rieger Begonia (basic knowledge):

The best propagation time: the best time for cutting propagation of Rieger crabapple is the end of autumn and the beginning of winter.

Best growing soil: Rieger crabapple likes substrates with good drainage, such as coconut bran, peat soil, vermiculite, perlite, carbonized bark, etc. 80% high-fiber peat soil and 20% perlite are recommended.

Growth humidity requirements: the early growth of Rieger crabapple requires higher relative air humidity, which should be controlled at 80%-85%.

The optimum growth temperature of Rieger Begonia is 18 ℃ ~ 22 ℃. The focus of family care is to keep warm in winter, and the minimum temperature should not be lower than 15 ℃.

Optimal growth light: Rieger crabapple is a quantitative short-day plant, which needs more than 70% shading when the summer temperature is above 25 ℃. Wait until late October, can appropriately enhance the light of Rieger Begonia, after mid-November for short-day treatment, try to fully receive the light, in order to ensure the growth and flowering.

3. The culture method of Rieger Begonia (specific operation):

1. Culture temperature

In terms of temperature, the suitable culture temperature of Rieger Begonia is 18 ℃ ~ 22 ℃, which is relatively high temperature. Therefore, Rieger Begonia likes a warm living environment and needs to pay attention to the lower temperature in winter. When raising Rieger crabapple, we need to do a good job of heat preservation in winter. The temperature of Rieger begonia overwintering in winter should not be lower than 15 ℃.

It should be noted that Rieger Begonia is still blooming in winter, so it needs to be kept dry to get plenty of light. You can put Rieger Begonia flowerpots in places where you can get in touch with more sunlight, such as south-facing balconies, windowsills and so on. Don't put it near the heater. And in summer, we also need to pay attention to the temperature, when the temperature is too high, we should take cooling measures to shade in time.

2. Farming and watering matters

Watering work should be carried out according to the specific situation. For example, in summer with a large amount of evaporation, you should water more, preferably in the morning or evening; in winter, it is best to water at noon, and the water temperature is not too low to avoid frostbite. Note that watering should be decided according to the condition of the basin soil.

In the daily management, you can increase the air humidity by spraying water. Pay attention to spraying water on the leaves, not on the flowers.

3. Culture light

In order to promote the growth of Rieger Begonia, it is necessary to make Rieger Begonia exposed to sufficient sunlight. However, in the growth process of Rieger Begonia, it is necessary to control the light. The shading work in the early stage of growth can not be reduced. Secondly, Rieger Begonia is a kind of plant with short sunshine, which often needs artificial light, and dark treatment is needed before flowering, and how to control the light well needs to be carried out according to the different climate of each region.

4. Fertilization

Fertilization is also the key to the growth of Rieger Begonia. The principle of applying fertilizer for Rieger crabapple is to apply fertilizer thinly.

The seedlings of Rieger Begonia need to apply some nitrogen fertilizer. When the plant grows up, it is necessary to reduce the use of nitrogen fertilizer and apply more potash and phosphate fertilizer. Before flowering, it is necessary to apply more fertilizer to ensure sufficient nutrients for flowering. You can also spray some not too thick foliar fertilizer.

1. During the growth period, Rieger Begonia should be coring to promote the plant to germinate lateral branches in order to achieve plump plant type, and the excess buds should be removed in time so as not to cause a large amount of nutrient consumption and affect the development of other flowers.

2. After the cool autumn, Rieger Begonia begins to sprout new branches from the base. When it grows to a certain height, the old branch is cut off from the base with a sharp knife, and the amount of water is increased to promote the growth of Rieger Begonia. When the new branches are basically shaped, 3 new branches are retained in each pot, and the rest are all cut off to concentrate nutrients and make Rieger Begonia take shape as soon as possible.

Pot soil replacement: Rieger Begonia can not be changed in the first two years because the purchased pot soil meets the requirements.

Main points of propagation: Rieger begonia is propagated by sowing method, cutting method or tissue culture method.

1. Sowing method. Because the seeds of Rieger Begonia are very small, the small seed sowing method must be used. The seeds of Rieger Begonia are basically imported, sub-coated and uncoated. Because the coated seed can be sorted, the hole seedling plate can be used, and the uncoated seed can only be used in the seedling tray. The sowing medium is peat soil and vermiculite powder, crushed and sterilized, then mixed and stirred, ready for use in a semi-wet state. Because peat soil is water repellent in dry state and cannot be watered, it can not be used in dry state. When sowing, first put the substrate on the nursery plate, and then pour water through the spray pot.

two。 Cutting method. At the end of autumn and the beginning of winter, the cut new branches can be used as cuttings when pruning and shaping the plants. Rieger begonia can be cut into branches or leaves. When inserting a branch, the length of the branch should be moderate, and the lower part of the branch should be cut into a horseshoe shape with a blade; when inserting leaves, six mature leaves with exuberant growth should be selected, and the lower end of the petiole should be obliquely cut with a blade. The cutting substrate is vermiculite powder or plain sand, and the contaminated substrate should be disinfected and reused. Water should be thoroughly watered after inserting the cuttings, but there should be no stagnant water on the leaves. And use plastic film to cover it, put it in the place of scattered light, properly ventilate and avoid high temperature. The cuttings can take root in about 3 weeks. When a new leaf is seen to grow, it shows that it has taken root. The plant obtained by branch cutting method has no underground tuber. After 3 weeks of leaf insertion, fibrous roots can also grow in the lower part of the petiole, but it will take another month and a half to grow adventitious buds from the petiole and gradually unearthed.

3. Tissue culture method. Tissue culture is a method to quickly obtain a large number of flower seedlings. In the growing season, a large number of virus-free seedlings can be obtained by non-toxic explant culture, subculture and rooting culture in a certain medium with well-developed leaves as explants. This method is expensive and can only be used in mass production.

Pest control: home-raised Rieger crabapple has fewer diseases and insect pests. Regular spraying of fungicides to prevent bacterial soft rot and powdery mildew can be sprayed with 1000 times of agricultural streptomycin 200ug/g. In order to prevent pesticides from polluting the air, some soil pesticides can be made, and the control effect is better. There are two common ways: (1) Ginger juice and water, spray at 1:25 ratio, can prevent soft rot and other pathogenic spore germination. (2) 50 grams of dried pepper, 50 times of water, boiling for half an hour, and spraying leaf surface with supernatant can effectively control aphids, red spiders and aphid mites, inhibit plant growth and make new leaves hard or linear.

5. Tips for cultivating Rieger Begonia:

1. When the growth of Rieger crabapple is slow or completely stagnant in summer high temperature, and is in a dormant or semi-dormant state, the residual flowers and withered leaves should be cut off and 50% to 70% of the light should be shaded; watering should be controlled to keep the soil slightly wet to prevent rotting of the rhizome caused by the excessive wetness of the basin soil.

2. Rieger crabapple is still in the period of growth and flowering in winter, so it should be placed in the south-facing sunny place indoors, such as on the indoor windowsill. When there is a high temperature lasting more than 28 ℃ in summer, cooling measures should be taken, such as putting it in an air-conditioned room or shading at noon.

[how to raise Rieger Begonia] matters needing attention in Rieger Begonia culture method

Rieger Begonia is an excellent flower to beautify the indoor environment in winter. Rieger Begonia is also one of the main species of indoor flowering plants in the four seasons. Family breeding of Rieger crabapple is different from large-scale production in greenhouse. If suitable environmental conditions can be created, Rieger crabapple will certainly add some color to your family. The following are the daily breeding methods and matters needing attention of Rieger Begonia. I hope the flower friends will be helpful.

How to raise Rieger Begonia (daily cultivation method) 1. Rieger Begonia Culture: temperature adaptation

The optimum temperature for growth and development of Rieger Begonia is 18 ℃ ~ 22 ℃. The focus of family care is to keep warm in winter, and the minimum temperature should not be lower than 15 ℃. As the winter Rieger crabapple is still in the growth and flowering period, it should be placed indoors facing south and sunny places, such as indoor windowsill and so on. But be careful not to get too close to the heater, so as not to burn the branches and leaves, and when there is a high temperature lasting more than 28 ℃ in summer, cooling measures should be taken, such as putting it in an air-conditioned room or shading at noon.

two。 Rieger crabapple culture: watering the right amount

The basin soil should remain moist, not dry and too wet; too dry will lead to water loss and wilting, and in serious cases, the whole plant will die; the basin soil is too wet, and the water fills the soil gap, resulting in serious lack of oxygen in the soil, which affects root respiration and death; too wet basin soil is also easy to provide opportunities for the infection of fungal and bacterial diseases, thus affecting the ornamental value of Rieger Begonia. Usually watering Rieger crabapple depends on climatic conditions, usually evaporation is fast in summer, water demand is relatively high, watering should be in the morning or evening, watering times depends on the wetness of the basin soil. Winter watering as far as possible in a sunny day at noon, the water temperature should be close to the indoor air temperature, so as not to cause root stimulation and death because the water temperature is too low.

3. Rieger Begonia Culture: rational fertilization

Regular fertilization is particularly important in the conservation of Rieger Begonia. Nitrogen fertilizer is the main fertilizer for seedlings to promote its growth and development, with the growth of the plant, the amount of nitrogen fertilizer should be reduced, the content of phosphorus and potassium fertilizer should be gradually increased, the amount of fertilizer should be increased before flowering, and foliar fertilizer can be sprayed properly. the concentration of foliar fertilizer should not be too high, controlled at 1% 2%, the spray should be uniform, and both sides of the leaf should be sprayed.

4. Rieger Begonia culture: integral pruning

During the growth period, coring should be carried out to promote the plant to germinate lateral branches in order to achieve plump plant type, and the excess buds should be removed in time, so as not to cause a large amount of nutrient consumption and affect the development of other flowers.

5. Rieger Begonia Culture: diseases and insect pests

There are fewer diseases and insect pests in family cultivation of Rieger Begonia. Regular spraying of fungicides to prevent bacterial soft rot and powdery mildew can be sprayed with 1000 times of agricultural streptomycin / ketamine. In order to prevent pesticides from polluting the air, some soil pesticides can be made, and the control effect is better.

Matters needing attention in Rieger Begonia culture 1. No fertilization during flowering

It is best not to fertilize the flowering stage of Rieger Begonia, and do not move the flowerpot casually, otherwise the flower bud will fall. Watering should be moderate, not too much water, so as to avoid stagnant water in the flowerpot and poor drainage of the soil.

2. Watering water quantity control

When watering, the water temperature needs to be close to room temperature. The suitable temperature for the growth of Rieger begonia is 15 ℃ ~ 22 ℃, and the temperature during flowering should be kept between 15 ℃ ~ 17 ℃. When the temperature increases gradually after May, Rieger begonia will enter a semi-dormant state and reduce watering.

3. Precautions in winter

Rieger crabapple will still blossom in winter, so to maintain the appropriate temperature, Rieger crabapple needs to be placed in the sunny place indoors for maintenance, and the south-facing windowsill is a good choice.

4. matters needing attention in summer

In summer, the sun is strong, need to give Rieger crabapple a little shade, it can grow well, but if the shade is too much, it will make the plant grow too much and affect the flowering.

5. Pruning of withered branches and residual flowers

When Rieger crabapple blossoms, it needs to cut off the withered branches and residual flowers.
