What are the breeding methods of flowers? The technique of split propagation of flowers

Meristem propagation is the main reproduction method of perennial flowers. Mainly making use of the characteristics of sprouting branches at the base or root of the plant, a part of the vegetative organs of the plant is artificially separated or cut from the mother plant, planted and cultivated separately, so as to form a new plant that lives independently.

Meristem propagation can maintain the genetic characters of plants, the operation is also very simple, is conducive to the survival of plants, seedlings are also very fast. It mainly includes ramet reproduction and ball reproduction, the following editor will tell you in detail.

1. Ramet propagation

Split-plant propagation, this method is mostly used for highly clustered flowers, is a method of dividing plants with roots into multiple plants. Such as chrysanthemum, white taro, orchid, peony, Hosta and other perennial root flowers, and wax plum, peony and other woody flowers can be propagated by individual plants.

According to the source of germinating branches, ramet propagation can be divided into three types. First, it is divided into short stolons, which is suitable for plants such as Liliaceae, Banana family, Palmaceae and so on. Second, the root tiller, the root tiller is the sprouting branch on the root, such as pineapple, sequoia and other plants are suitable for this method of reproduction. Third, divided into roots, Dutch chrysanthemum, eight immortal flowers, hairpins and other herbs and cherries, oleander, tang and other woody plants can be propagated in this way.

In addition, there are sub-bead bud method and sub-stem method, lily, lily and so on can use sub-bead bud method. Saxifraga, Chlorophyllum, Buffalo grass can be used to split the stem method.

2. Reproduce by dividing balls

Bulblet reproduction is a method of reproduction by using underground abnormal organs or specialized organs with storage function. There are many kinds of underground metamorphosis organs, which can be divided into bulbs, bulbs, tubers and rhizomes according to their variation sources and characters. Therefore, green friends should pay attention to different plants using different ways of reproduction.

1. Bulb

The bulb is composed of small scales, and the vegetative meristem in the center of the bulb develops in the axilla of the scale, producing small bulbs. Bulbs, bulbs and scales can all be used as reproductive materials. Daffodils, tulips and bulbous irises are often propagated by growing bulbs.

two。 Bulb

The corm is an inflated underground abnormal stem at the base of the stem axis, which is spherical and is the storage vegetative organ of the plant. After the germination of the old corm, a new ball is formed at the base, and a sub-ball is formed next to the new ball. The new ball, sub-ball and old ball can be planted separately as a vegetative form.

3. Tuber

The tuber is the metamorphosis of the underground stem formed by the expansion of the subapical part of the stolon. The tuber is the organ of storage and reproduction. The propagation of the tuber can be carried out with the whole tuber or cut with buds. Jerusalem artichoke and artichoke can be propagated by this method.

4. Rhizome

Rhizome is a specialized stem structure. Rhizome propagation is usually carried out in the early stage of the growth period or at the end of plant growth. When cutting rhizome segments, it is necessary to ensure that each segment has at least one lateral bud or bud hole, which is actually equivalent to stem propagation.

In addition, there are many ways to propagate plants. what else do you know? Welcome to leave messages and exchange messages in the comments area below. If you want to know more about agricultural technology, please follow Huinong School!

A brief discussion on the Technology of split Propagation of Family Flower

There are flowers and plants (annual flowers, biennial flowers), flowers and trees (trees, shrubs, vines,). Due to different species, their reproduction methods are also different. the common methods are split-plant method (for tufted and sprouting flowers) and ball-dividing method (for bulbous flowers). Next, the editor will briefly talk about the technology of family flower reproduction. I hope it can be helpful to everyone.

I. split-plant method

1. The meaning of ramet method.

The method of plant division is to cut off the sprouting or walking stem of the root neck of the mother plant into a new plant, which has the advantages of high survival rate and keeping the characteristics of flowers unchanged.

2. Flowers suitable for ramet

One-leaf orchid, Guanyin bamboo, calla lily, iris, day lily, gentleman orchid, canna, Tianmenong, palm bamboo, stone lotus and corm, bulb flowers and so on.

3. The best period for ramet.

Spring is the best, autumn is also fine, of course, some flowers are not limited by season.

4. Preparation before ramet

Sterilized sharp knife, new basin, culture soil, sulfur powder, mosquito incense ash.

5. Operation steps

① rhizome flowers such as orchids, asparagus, hairpins, orchids, calla lilies, etc.

First, remove the flowers from the original basin, then cut vertically at the rhizome with a knife, cut into 3-4 pieces, each with stems, leaves and roots, apply sulfur powder or mosquito incense ash antiseptic in the incision, and plant them into prepared new pots.

② bulbs and bulbs such as tulips, gladiolus, evening fragrant jade, lilies, etc.

After the flowers bloom, the bulbs are dug out in summer, the bulbs are broken off and dried, stored and cultivated at the right time.

③ large flowers such as brown bamboo, ginkgo biloba, etc.

Cut off part of the root with budding eyes from the mother plant, coat the cut with plant ash or sulfur powder for embalming, and plant it in a prepared basin.

6. Management after ramet

Water thoroughly, place in a cool and ventilated place, and move to the sun a few days later.

Second, the method of dividing the ball

1. The advantages of the ball-dividing method: it blossoms earlier than sowing and reproduction, and the method is simple.

2. The newly produced tubers, corms, rhizomes, bulbs and tubers are naturally separated and planted separately, and they will grow into independent new plants.

3. The time of dividing balls: most of them are carried out during the dormant period or before the bulb is harvested and planted.

The technique of split propagation of flowers

The technique of split propagation of flowers

1. Define

Meristematic reproduction is a method of reproduction by artificially separating or dividing a part of the young plant or vegetative organ of a plant from its mother plant and planting it separately to form a new plant that lives independently.

two。 Method

According to the different kinds of flowers, meristem reproduction can be divided into plant division method and ball division method. The ramet method is mainly used for bushy shrubs and perennial flowers with strong sprouting ability, and the bulb method is mainly used for bulbous flowers.

The main results are as follows: (1) this method is a simple method to propagate flowers and trees. it has the advantages of high survival rate and fast seedling growth, but less seedling production. Ferns, asparagus, tiger tail orchid, brown bamboo, pepper grass, begonia, hanging orchid, gentleman orchid and other commonly used breeding this method.

① ramet time: deciduous flowers and trees, ramet propagation should be carried out in the dormant period.

The south can be carried out after the defoliation in autumn, because there is no cold in the south in winter, the air is relatively humid, some flowers and trees can grow some new roots before the beginning of winter, the branches will not be drained in winter, and it can also reduce the tension of busy labor force in spring.

In the north, it should be carried out before the soil is thawed at the beginning of spring and the plant has not sprouted, because the winter in the north is cold and the air is dry. Except for the potted flowers and trees that overwinter, most of the ramet seedlings in autumn have a low survival rate, so they should be arranged before sprouting in early spring.

Evergreen flowers and trees have no obvious dormancy period, but most of them grow slowly or are in a semi-dormant state in the maintenance stage of greenhouse in winter. Autumn ramet, not only is not easy to produce new roots, a large number of ramet seedlings will also increase the pressure of the greenhouse, so it should be carried out in spring, moving out of the greenhouse on the one hand and de-pot ramet on the other.

② ramet method: there are many methods.

To propagate with tillers: cut off the tillers occurring in the rhizosphere or underground stems and plant them to form independent plants. Such as Chunlan, Hemerocallis, Hosta, a yellow flower and so on. In addition, hollyhock and Sugen Fulu can produce "root tillers" from their roots. This method can also be used by some lawn ground cover plants in Gramineae. In horticulture, the method of cutting roots is also used to promote its rooting and tillering to increase the reproduction coefficient.

Propagation by sucking buds: sucking buds are short, thick, rosette-shaped short branches naturally occurring in the rhizosphere or the axils of aboveground stems and leaves of some plants. The lower part of the sucking bud can take root naturally, so it is separated from the mother plant and planted separately. For example, aloe and Sedum often suck buds in the rhizosphere; sucking buds can also be produced in the armpits of the aboveground stems and leaves of pineapple, which can also be propagated by this method. Gardening is often used to hurt its roots to stimulate these plants to sprout.

The use of bulbs and surplus seeds for reproduction: bulbs are special forms of buds of some plants, some of which are born in the axils of leaves, such as lilac; others are born in inflorescences, such as ornamental onions. More than zero-bulbous or tuberous, such as Dioscorea zingiberensis.

After leaving the mother plant, the bulbs and their offspring can take root naturally, and this habit is often used for propagation in horticulture.

Propagate with walking stem or stolon: walking stem is a longer Internode stem drawn from leaf clusters, with leaves, flowers and adventitious roots on the nodes, and young plants can also be produced. Separated plantlets can be planted separately to form new plants. The flowers propagated by walking stems are Saxifraga, Chlorophyllum and so on.

The stolon is similar to the walking stem, but the internodes are shorter, walk across the ground, and produce adventitious roots and buds at the nodes, which are more common in grass grass, such as dog bud root, buffalo grass and so on.

(2) the underground part of most bulbous flowers have strong ability to grow, and some new bulbs can be produced every year, which can propagate earlier than sowing and blossom. The new bulbs (tulips, lilies), bulbs (gladiolus, freesia), tubers (cyclamen, calla lilies), roots (canna, lotus), roots (dahlia), etc., will be planted after natural separation. It will grow into a new independent plant. The dividing time varies with different species, and generally takes place in the dormant period of plants in spring and autumn.
