Is calla lily grafted or cutting? How calla lilies reproduce

Calla lilies are propagated by cuttings or seeds.

1. The propagation methods of calla lily include sowing propagation and cuttings propagation.

2. Sowing and propagation is to evenly sprinkle seeds in fertile soil, the gap between seeds should not be too high, apply organic fertilizer appropriately, choose water-soluble fertilizer with high safety factor, safe and secure products, water-soluble fertilizer for fertile leaves, etc., reasonable fertilization, not too much.

Abstract The main method of propagating calla lily is the dividing method and the sowing method, and the dividing method is more extensive, and the sowing method is only used when the temperature is the most suitable. Prepare soil and pots for dividing plants, separate the plants from the roots with a knife, and plant them separately. The sowing method should be carried out at about 20 years, select full seeds, cover the soil after sowing, put them in a semi-shaded position, and wait for germination.

Calla lilies can be cut from seedlings that come out of the root part.

1. Dividing method.

1. Time selection: It is best to choose in September, which can be combined with changing pots.

2. Preparation of flower soil and flower pots: You can buy special soil for sleepy answers, or you can match it yourself. It can be prepared by mixing garden soil, humus soil and base fertilizer. Flower pots can be prepared with several more, preferably of different sizes. Split wheel.

3. Divide the plant: Prepare a sharp knife, and it is best to disinfect it before use. Divide the plant by removing it from the pot and shaking off the soil from the roots.

Don't divide it into too many parts, just two to four pieces. After that, apply some plant ash to the incision. Depending on the size, plant each part in a pot.

4. Post-maintenance: first put it in a semi-shaded place, without strong light. Keep the potting soil moist. After germination, it can be maintained normally.

Second, the sowing method.

1. Time selection: This method is not commonly used because it has relatively high temperature requirements. The temperature must be around 20 to proceed. Moreover, it is also less likely to succeed than the first one.

2. Seeds, flower soil: choose the healthier ones. The preparation method of flower soil is basically the same as that of the flower soil preparation method of the dividing method.

3. Sowing and maintenance: sprinkle the seeds into the soil and cover with a thin layer of soil. After that, place it in the semi-shade and wait for it to sprout.

The cultivation soil should contain slightly acidity, and the growth is mainly based on basal fertilizer, and calla lilies prefer fertile and loose slightly acidic soil.

Use fertile and slightly clay soil, such as: 2 parts of garden soil, 1 part of chaff ash, and a little bone meal or manure; You can also use 2 parts of finely crushed pond mud, 1 part of humus (or compost), add an appropriate amount of superphosphate and decomposed cow dung to prepare the soil.

It prefers loose and fertile, rich humus and sandy loam.

Calla lily is a perennial herbaceous plant of the genus Calla lily in the family Araceae. The flowers and leaves have high ornamental value, and in recent years, colored calla lilies have become popular. Calla lilies are a good material for potted plants and cut flowers. Small flowers are suitable for flower beds, and large flowers are suitable for flower landscapes and small gardens.

1) Propagation by tubers. Tuber propagation can be carried out in spring and autumn, after the main flowering period, or during dormancy. The mother plant is dug out of the soil, and the budding balls formed around the tuber are peeled off and planted separately.

The soil in which the pellets are cultivated should be fertile and loose. Planted according to the row spacing of 20 cm and the plant spacing of 10 cm, covering the soil with 2 cm. Keep the soil moist.

Potted plants chase liquid fertilizer once every 7 to 10 days. Remove small florets as soon as possible during growth. Grow for 1 year to form flowering bulbs.

2) Sowing seedlings. Seeds can be harvested when the climate is suitable. From early February to late April, robust, large calla lily varieties are selected for artificial pollination.

Gently tear off the bracts at the beginning of flowering so that the pistils in the lower part of the spike are fully exposed. Pollination should be sufficient, pollination 1 time a day, 2 3 times in a row, with cross-pollen. During this period, the temperature should be controlled at about 20 during the day and about 10 at night, and the temperature should not be too high.

The ovary was significantly enlarged about 15 days after pollination, and the fruit ripened about 2 months. The fruit is spike-shaped, orange-yellow, and each inflorescence can produce about 250 seeds. Wash off the pulp, dry and store in a ventilated and dry place.

Sowing in August, soak the seeds with warm water before sowing, and then promote germination, germination in about 15 days, good seed germination rate is more than 90%, and then sowing. After sowing, proper shade, soil moisture should be larger, temperature control 18 24, 7 days or so seedlings. Seedlings grow into flowering bulbs in 2 to 4 years.

3) Tissue culture seedlings. At present, colored calla lilies are mainly used for tissue culture seedlings. Use tuber buds or bud eyes as explants.

Induce with MS medium, add 1 2 mg of 6-benzyladenine and 1 kg of naphthalene acetic acid. MS medium for proliferation, plus mg kg of 6-benzyladenine and mg kg of naphthalene acetic acid. MS medium for rooting, plus mg kg of naphthalene acetic acid and mg kg of indole butyric acid.

Temperature control 22 26 , light 10 14 hours, illumination 1000 2000 lux.

4) Tuber storage. After the leaves wilt and go dormant, the tubers have a dormant period of about 3 months. The tubers are harvested when the leaves are withered, and the tubers are dried in an environment with a temperature of 17 20 and a relative humidity of less than 60% for 2 weeks, and then cooled to 13 9, increasing the relative temperature of the air to 75% 80%, and can be planted after 3 months of storage.

After harvesting, the tubers of calla white-flowered lily are placed at 20 30 for 7 days, and then stored at 9 2 for no less than 40 days.

It is advisable to fertilize the potting soil with 1 part of loam, humus and coarse sand, and then add an appropriate amount of bone meal, manure and superphosphate. During the growth period, it is advisable to top dressing once every half month, and do not pour fertilizer into the petioles. When the vegetative growth is too much, the leaves should be thinned in time to facilitate the extraction of the flower stalks.

In addition to maintaining sufficient water during the growth period of watering calla lilies, it is advisable to spray water on the nearby ground in the morning, noon and evening to increase air humidity.

In autumn, winter and spring, if the light is insufficient, the calla lily only buds but does not bloom, and even the flower buds gradually turn green to wilt. When the sun is too strong in summer, you should take measures to avoid light, otherwise the leaves are easy to turn yellow or wilt.

Propagation calla lily propagation can be planted in autumn by taking the daughter balls that germinate on the rhizome. After planting, it is placed in a shaded place, and only after the buds are raised in the sun. When the frost falls, enter the room in a sunny place, keep the room temperature at 10, and not lower than 0 at night.

Calla lily generally begins to bloom early in November, and can bloom until May of the following year, with March to April as the full flowering period, but if properly maintained, it can also make it green and colorful in all seasons, and the specific measures are as follows:

The temperature control temperature for calla lily growth is 10 to 25. Since the air is relatively dry in autumn, it is necessary to control the temperature at about 20 and the relative humidity at 85%. In winter, if the room temperature can be maintained at night above 10, it can grow and bloom; High temperatures in summer and low temperatures in winter can cause plants to become dormant or wilt.

At 0, the rhizome of calla lilies will freeze to death. Keeping the winter warm and the summer cool is one of the main conditions for flowering throughout the year.

The original grandchildren of calla lilies are absent in the Cape of Good Hope area of South Africa, and Bi Kai's burning hands are weak and warm, and they are not cold-tolerant.

Calla lily can be planted with seeds or in autumn with balls (sprout balls germinating around the rhizome), the soil should be fertile soil with strong water retention, the environment should be kept moist and slightly shaded, and placed in the sun after germination. In the frost season, the north needs to enter the greenhouse, the temperature is kept above 10, and the night temperature is not lower than 0. During the growth period, top dressing once every half month, do not pour fertilizer water into the petioles.

When the leaves are luxuriant, the leaves should be thinned in time to facilitate the extraction of the peduncles. Calla lily begins to bloom around the Spring Festival, and the flowering period is from March to April, and fertilization is stopped at this time. After May, water less to let it dormant, take out the bulb after the leaves are yellow, put it in a ventilated and cool place, and then plant it in a new pot in autumn.

Store for a few more days or make dried flowers.

Insert bottles of calla lilies for preservation.

Calla lilies can be stored for several days in dark, low temperature (4 degrees Celsius) and high humidity (90 degrees). Calla lilies should be kept away from direct sunlight or other heat sources, as well as large household appliances. If you find a dry or damaged flower or leaf, remove it immediately.

The container for calla lilies should be soaked in a bleach solution (one teaspoon of bleach per liter of warm water) for at least 1 hour before use. Clean flower preservation solution should only be placed in a clean container.

To make dried flowers at home, due to the limitations of equipment and other conditions, two simple and easy methods can be adopted.

1) Natural drying method. This method is to leave the flower material in a cool, dark, dry, clean and well-ventilated place to allow it to air dry. It is suitable for grass flowers with more cellulose and is used when making three-dimensional dried flowers.

The method is to collect the flowers in the morning after the dew has dried. After harvesting, cut the stems to the desired length, remove a few leaves and excess side branches and damaged parts, and tie them into appropriate bouquets with thin strings, so that the flowers hang downwards on the wire.

As the flowers dry, the original tied bouquet is easy to loosen, so you need to pay attention to tying it tightly at all times. After the branches are thoroughly dried, spray with anti-transpiration agent and put them in a large box for later use. For some flowers with thin and tender petals, which are easy to roll and deform when hanging upside down, the pinned drying method can be used, that is, the metal tissue mesh or other porous flat materials are selected, and the lower end of the flower branch is vertically passed through the mesh, so that the flowers are stretched and stretched on the mesh to let it air dry naturally.

2) Normal temperature pressing method. This method is a commonly used method for making flat dried flowers. Put the flower branches in the absorbent paper, place them on a flat plate, press a heavy object (such as stones, bricks, etc.) on top, place them in a well-ventilated place, and be confident that they will dry naturally.

In the mass production of dried flowers, specimen holders can be used instead of heavy objects. With this method, it should be noted that after 1 to 3 days after pressing, the moisture absorbent paper needs to be replaced in time. This method can also be combined with heating and rapid drying, that is, on the second day after the flowers are pressed, or when they are about to dry, the hygroscopic paper with an electric iron is gently burned a few times, and then pressed as usual to allow it to dry thoroughly.

This not only dries quickly, but also plays an insecticidal and sterilizing role, which is conducive to the preservation of dried flowers. However, some flowers, such as orchids, will fade when exposed to high temperatures, so such flowers should not be warmed.
