Maintenance method of Zhu Dinghong

In the middle of June, cut off the residual flowers and withered yellow flowers and leaves, put them in a cool and ventilated place, and re-apply nitrogen, phosphorus and potassium compound fertilizer, and then apply concentrated phosphate fertilizer every 10 days except watering once a day. Put in the open air, if the sun is too strong, you can properly shade and spray in time. In late July, Zhu Dinghong can blossom again.

2. After the flowers fade in late August, cut off the residual flowers and apply concentrated fertilizer once, preferably mature organic fertilizer. In the middle of September, Zhu Dinghong was placed in a sunny room of about 13 ℃, watering less, not drying the bulb, watering once every 10 days, less fertilizer or no fertilizer, so that it went through a short dormancy process.

In the first ten days of November, Zhu Dinghong was moved into the greenhouse and the temperature was controlled at about 22 ℃ and watered once every 3-4 days to promote leaf bud germination. After the new leaves are extracted, the mixed liquid fertilizer based on phosphate fertilizer is poured once, and nitrogen, phosphorus and potassium compound fertilizer is applied once every half month before budding, so that Zhu Dinghong will blossom for the third time in the next Spring Festival.

3. After the flower fade, the flower stem and aboveground parts should be cut off in time, and the watering should be reduced or even not watered, so as to keep the bulb fully dormant in the low temperature environment, so as to lay the foundation for Zhu Dinghong to blossom at the natural flowering stage.

The above is the introduction of Zhu Dinghong's flowering times and maintenance methods in a year. If you want to know more about Zhu Dinghong, please pay attention to the four Seasons Plant Network!

Culture method of Zhu Dinghong

Zhu Dinghong blossoms in April in spring and blossoms again in winter. Management should be strengthened as soon as possible to promote flowering. Fast growth, after 1 year of growth, should be replaced with adaptive flowerpots. The red pot soil of Zhu Ding has been planted for 1 or 2 years, and the basin soil is lack of fertilizer. In order to promote the growth and flowering of the new year, it should be replaced with new soil. The growth is fast, and there are many bulbs growing in the head after 1 or 2 years, so the plants are divided at the same time when changing the basin and soil, so the co-planting of large plants is one pot, that of middle plants is one pot, and that of small plants is one pot. The bottom fertilizer should be applied at the same time when changing the basin, changing the soil and planting, and the phosphorus and potassium fertilizer should be applied once a month after the pot is put on the pot. the principle of fertilization is thin application to promote flower bud differentiation and flowering. Zhu Dinghong grows vigorously and blossoms as soon as possible. Pest control should be carried out. Anthers should be sprayed once a month. Anthers should be sprayed around 9: 00 a.m. and 4: 00 p.m. on a sunny day, and should not be sprayed in the hot sun at noon to prevent drug damage.

Zhu Dinghong likes warm and humid climate, the suitable temperature for growth is about 23 ℃, avoid extreme heat, the sun should not be too strong, should be maintained under the shade. I'm afraid of flooding. During the dormant period in winter, a cool climate is required, which should be 11 ℃ and not less than 5 ℃. Like sandy loam rich in humus and well drained. The artificial cutting ball method is often used to propagate a large number of seed balls. That is, it is cultured by sowing, dividing balls, cutting bulbs, tissue culture and so on.

Culture method of Zhu Dinghong

The breeding method of Zhu Dinghong is better than that of Magnolia, which is very suitable for family cultivation. The following will be introduced as follows: the morphological characteristics of Zhu Dinghong: perennial bulbs. The large bulb has a diameter up to 6cm-10cm, and the color of the scale is related to the color of the flower. The brown scale is a red flower, and the light green one has white or red stripes. The root is born under the bulb, and the leaves are drawn from the bulb, inserted in two rows, 3-4 on each side, flattened and light green. The flower stem is also drawn from the bulb, green, stout and hollow. Umbels bear the tip of the stem, trumpet-shaped, with red, red with white stripes, white with red stripes, often 2-6 flowers relatively open.

The suitable temperature for growth is 18 ℃-25 ℃, and the optimum temperature for winter dormancy is 5 ℃-10 ℃. Like moist, afraid of waterlogging, like loose soil rich in organic matter, good drainage. Like fertilizer, but after flowering, nitrogen fertilizer should be reduced and phosphorus and potassium fertilizer should be increased to promote bulb hypertrophy.

The main species and varieties are Guting flower, Wang Baizhilian, Huazhong orchid, reticulated Baizhilian and hybrid Baizhilian and so on. There are many kinds of horticulture.

Main points of multiplication: dividing balls and sowing and propagating. The bulbs around the mother ball are about to be removed and propagated, which will be carried out from March to April. When taking the ball, do not damage the root of the ball, potted or planted on the ground, and the top of the bulb should be exposed to the soil surface when covering the soil. In cold areas, bulbs should be dug up in late October. Bulbs with a diameter of more than 6cm-7cm can be planted in pots for flowering, while bulbs should be stored in dry sandy soil and replanted in April next year. Flowering bulbs can be formed after 2 years of planting. In addition, a large number of balls can be obtained by cutting and propagating scales in the high temperature season from July to August. The optimum temperature of cutting is 27 ℃-30 ℃, keep it moist, and after 6 weeks, it can produce pellets and take root. Planting should not be deep, too deep causes the neck to grow slender; shallow ground temperature is high, root group growth is exuberant. It is planted from March to April and blossoms from May to June. Fully irrigate at flowering stage, increase topdressing after anthesis, place in semi-shade place in midsummer, stop growing gradually after August, water content decreases to stop watering, keep dry in winter, and keep 10 ℃-13 ℃ to promote its full dormancy.

Brief history of cultivation and flower culture: native to the tropics and subtropics, such as the Andes in Peru, the Cape of good Hope in South Africa and Brazil in South America, it was introduced into Europe in 1633 and 1769 respectively. The Dutch studied the florescence of Zhu Dinghong and bred plants that could blossom at Christmas and New Year's Day, so that this beautiful red blossom could bloom according to people's needs. Zhu Dinghong is not only used as a potted plant, but also a high-grade cut flower. It is loved by people because of its long flowering period, and it often becomes the material written by painters.

Zhu Dinghong spring management

Zhu Dinghong blossoms in April in spring and blossoms again in winter. Management should be strengthened as soon as possible to promote flowering.

1. Change the basin. Zhu Dinghong grows fast and should be replaced with a suitable flowerpot after growing for one year.

two。 Change the soil. The red pot soil of Zhu Ding has been planted for 1 or 2 years, and the basin soil is lack of fertilizer. In order to promote the growth and flowering of the new year, it should be replaced with new soil.

3. Ramet. Zhu Dinghong grows fast, and after growing for 1 or 2 years, there are many bulbs growing on the head, so it is necessary to split the big plants into one pot, the middle plants into one pot, and the small plants into one basin at the same time.

4. Fertilize. Zhu Dinghong should apply base fertilizer at the same time when changing basin, soil and planting, and apply phosphorus and potassium fertilizer once a month after potting, the principle of fertilization is thin application, in order to promote flower bud differentiation and flowering.

5. Trim. Zhu Dinghong grows fast and its leaves are long and dense. It is necessary to cut off fallen leaves, withered roots, diseases and insect pests while changing pots and soil, leaving exuberant leaves.

6. Control diseases and insect pests. In order to make Zhu Dinghong grow vigorously and blossom as soon as possible, pest control should be carried out. Anthers should be sprayed once a month. Anthers should be sprayed at around 9: 00 a.m. and 4: 00 p.m. on a sunny day, and should not be sprayed in the hot sun at noon to prevent drug damage.

The above six points are the work that Zhu Dinghong should pay attention to in spring management.

Breeding method of Zhu Dinghong:

Zhu Dinghong is a perennial herb with a spherical bulb with a diameter of between 10 and 15 cm. The sword-shaped leaves are neatly arranged, the veins of the sword leaves are clear, and the leaves are green and shiny. Flowers are mainly red, yellow, pink, green, orange, complex color and other colors, florescence 10 to 20 days. Because of its strong ornamental value, it is widely cultivated all over the world. Red red can be propagated by sowing, ball distribution and tissue culture and other methods, several commonly used are introduced below.

First, newspaper sowing method Zhu Ding safflower blossoms after artificial pollination after more than a month of natural cracking of the fruit, seeds can be harvested. Sow the seeds after drying for a day or two. Draw a square 3cm long and wide on the newspaper, then put it on the seedling bed (not in direct sunlight), spray water and put a seed in each grid, then cover it with a wet newspaper. Spray water twice a day to dry the newspaper, and the seeds grow seedlings from under the newspaper for about 15 days (temperature 18 ℃ to 24 ℃). Wait for the seedlings to grow two true leaves, and then divide the seedlings into the large plate, the substrate is vermiculite and peat soil, and pour nutrient solution. Wait for the seedlings to grow 6 to 7 leaves before they can be cultivated in the field.

2. shallow pot sowing method is sifted with culture soil and vermiculite and then put into shallow.

In the basin, 3 cm from the mouth of the basin, then water it. After the soil is wet, sow the seeds on the soil surface according to 3 × 3 cm, and then cover it with sifted soil, not too thick. Cover the shallow mouth with glass after sowing and place it in a place where there is no light, a temperature of 18 ℃ to 24 ℃ and a humidity of 80% to 90%. About 10 days later, the seeds begin to germinate. The gap of the glass plate can be adjusted slowly until all of it is opened. When the seedlings have three or four leaves, they can be planted in pots or on the ground.

Third, the ball breeding method is generally combined with Zhu Dinghong to change the pot to break off the excess balls, directly potted or planted on the ground.

This method is simple and easy and the survival rate is high. If the divided bulb is a strong bulb of more than 5 centimeters, it can blossom in the same year. Smaller bulbs can blossom in about two years.

IV. tissue culture and reproduction are commonly used.

In MS medium, stem disc, dormant bulb tissue, pedicel and ovary were used as explants. Callus was produced after tissue culture, adventitious roots were formed after 30 days, and adventitious buds were formed after 3 to 4 months. When the leaves grow to 4 cm, separate, and then 2 months later, the seedlings can be put into the greenhouse management.

Question: my Zhu Dinghong plant was given to me by my friend ~ I like it very much ~ but the ball is not small after raising it for 2 years. My colleagues all say it's time to blossom ~ but it doesn't blossom ~ I fertilize and water it regularly. What's going on?

Answer:

I guess I took too good care of it. It would be better to do a little bit in autumn and winter.

This thing is easy to raise. Φ blossoms in 5cm last year, usually let it dry a little bit, and fertilize it every 7-10 days in autumn to make it as long as possible. Grow up, cut off the leaves in winter and let it dormant. Turning over the pot and applying enough basic fertilizer will produce beautiful flowers next spring. My family can blossom again in October.

I think it is caused by more nitrogen fertilizer and less phosphorus and potash fertilizer. In addition, it is time to change the soil and divide the basin after raising it for two years.

The natural florescence of this flower is from April to May. Let bygones be bygones. However, nitrogen, phosphorus and potassium compound fertilizer can be applied once in mid-June, and phosphate fertilizer can be applied every 10 days in addition to normal watering. In late July, Zhu Dinghong still has a chance to blossom.

The key to the flowering of Zhu Dinghong is the management in winter. after entering the winter, we must stop watering and let it go into a dormant period before it can blossom in spring. If fertilizing and watering in winter will lead to overgrowth, the bouquet can not be conceived, it will not blossom. In short, the fewer leaves in winter, the better.

Let it fully dormant in winter, cut off all the leaves, and water it once in spring to wake it up.
