What is the relationship between striping and ramification?

Explain in detail the "two different types of "seedling" methods in the "strip" propagation method.

Advantages: fast reproduction, can be cultivated in a large number of new plant individuals in a short period of time; It can prevent the harm of plant viruses.

Disadvantages: Its application range is inferior to seed propagation and cuttings, because its time-consuming propagation efficiency is low.

Pressing strips, also known as pressing branches, is to bury the branches of flower plants in moist soil, or wrap the branches with other water-retaining substances (such as moss) to create dark and moist rooting conditions, and after they take root, they are cut off from the mother plant to make them new plants. It is the same as cuttings propagation, it uses the regenerative ability of plant organs to reproduce, and is mostly used for some cuttings that are difficult to take root, or some woody flowers with more roots and leaves. Its fundamental characteristic is that it is separated from the vegetative organs of the mother, has the ability to regenerate, and can grow adventitious roots and adventitious buds in the part of the body, so as to develop into an independent living plant.

Strip method. It is a method in which the branches of a plant are pressed into the soil or wrapped in soil, and after rooting, they are separated from the mother plant to form an independent new plant.

The stripping method is further subdivided into the low-pressure method (bending the branches into the soil, such as oleander, etc.). ) and high-pressure method (cutting or ring stripped branches that are not easy to bend and wrapping them in sand, such as white orchids, etc.).

Grafting. That is, a part of plant A (scion) is grafted to the branch (rootstock) of plant B to heal it into an independent new plant. Scions are generally excellent varieties that can maintain their excellent characteristics after grafting; The rootstock is generally a wild species, with a well-developed root system and strong growth, and grafting excellent varieties on it can make the plant grow vigorously.

The grafting method can be subdivided into four types: branch grafting, bud grafting, leaning grafting and flat grafting.

5-10 garden plants that are adapted to the propagation method of pressed ramets and strips are cited.

Strips: wax plum, Xinyi, grapes, Huye camellia, leaky osmanthus, longan, lychee roots: paulownia, black locust, catalpa, sumac, toon, stinky toon, jujube tree grafting:

Persimmon, citrus, apple, cucumber, peach, nectarine, apricot cuttings: yueji, cactus, dragon cypress, cedar, chrysanthemum branch: palm bamboo, phoenix bamboo, peony, peony, orchid, evergreen pants shout.

Evergreen plants, as well as some plants whose seeds are not easy to propagate, can be propagated by the above methods.

In fact, these reproduction methods are artificially controlled, in order to promote its growth and development more quickly, and some of the methods adopted for more reproduction are not unique characteristics of the plant itself.

So you should ask how a certain plant should be grafted, cut or striped.

In general, shrub plants are propagated by striping or cuttings, tall perennial woody plants are mostly propagated by grafting, and herbaceous plants are mostly propagated by cuttings, and occasionally grafted.

Strips: wax plum, Xinyi, grapes, camellia, osmanthus, longan, lychee roots: paulownia, black locust, catalpa, sumac, toon, stinky toon, jujube tree grafting: persimmon, citrus, apple, cucumber, peach, nectarine, apricot.

Cuttings: moon season, cactus, dragon cypress, cedar, chrysanthemum.

Branches: palm bamboo, phoenix bamboo, peony, peony, orchid, evergreen.

The branches of the lower part of the mother plant are pressed down and buried in the soil, so that the adventitious buds of its nodes or internodes germinate and grow new roots, and then they are cut off from the mother body and planted separately to form a new plant, this propagation method is called strip propagation.

Strip propagation is mostly used for flowering shrubs with strong clumps or vines with soft branches. For some trees and shrubs that are difficult to root, they can also be propagated by high branch pressing strips.

The advantages of strip propagation are easy to survive, fast seedling formation, and simple operation method. The disadvantage is that the body of the seedling is not completely renewed, the growth is not vigorous, the seedling yield is small, and it is not suitable to be used when producing seedlings in large quantities.

Small trees such as peach blossoms, cherry blossoms, plum blossoms, begonia flowers, magnolias, bauhinia, and begonias can be pressed with long branches germinating from the main trunk when propagating in small quantities. Before pressing the strip, it is necessary to press the buried part for a heavier wound, and when conditions permit, it is best to apply 2000 micrograms of naphthalene acetic acid to the wound area, and then bury the wound part in the soil, press it with a heavy object, and insert a bamboo pole to support it at the same time, so that the branch tips grow upright and upward. The pressed strip seedlings in spring should be cut off from the mother body one month before the leaves fall, and the seedlings should be dug out before winter, and the seedlings can be directly planted on the nursery ground in the south to continue to cultivate large seedlings; In the north, ditches should be dug and planted falsely, and at the same time, the soil should be buried to prevent the cold, and the planting should be carried out in the spring of the following year.

Honeysuckle, wisteria, Lingxiao, Luoshi, grapes, creepers, woody incense and other vine flowers and trees, can be branches nested into wavy when propagating, 1 section buried in the soil, 1 section exposed to the soil surface, at the same time with a barb-shaped branch or " " " shaped lead wire inserted into the soil, the depth of the buried branches should not exceed 3 cm, about 20 days can take root, axillary buds then sprout unearthed, and then grow new branches.

The branches of lilacs, elm leaf plums, begonias and other flowers and trees are relatively thick, and when they are propagated in large quantities, they can choose the perennial clumps of old plants as the mother parent, first make a larger wound at the base of each branch, and then hug up the mound to bury the base of the whole cluster to keep the mound moist. After a period of time, a large number of new roots may sprout at the wound site, and in late autumn or early spring the next year, the mound will be peeled open, and they will be gradually cut from under the new roots, and then the seedlings will be planted.

The stripping method is as follows:

Ordinary beads. It is suitable for plants with soft branches and vines, or tree species with many flexible branches near the ground (Xinyi, wax plum, etc.). Bend the 1-2-year-old branches of the mother plant near the ground in all directions, press them into the pit after being carved below, fix them with hooks, compact the soil, and expose the ground slightly vertically upwards and insert a support.

Principle: The nutrients transported by the sieve tube in the wounded part of the pressed strip cannot be transported, so they accumulate in the wound and gradually develop into roots. ）

Horizontal beading. It is suitable for tree species with long branches and easy rooting (e.g., apple dwarf anvil, vine moon, etc.). It is also known as continuous pressure and trench pressing.

Dig a shallow ditch along the branches, cut the branches at appropriate intervals and fix them horizontally in the ditch, remove the buds that grow downward on the branches, and fill the soil. After rooting and germination, the internodes are cut off one by one, and each seedling is attached to a section of the mother.

Corrugated beads. Suitable for vines with long branches (such as grapes, etc.). The branches are bent up and down into a wave shape, and the part that touches the ground is buried in the compacted soil, and after a certain period of time when it takes root and protrudes from the ground, it is cut into new plants one by one.

Pile of earth strips. It is suitable for trees with strong tillering or clumps in the root neck part (such as Xinyi, pearl plum, yellow thorn rose, plum, pomegranate, etc.). The base of the root neck branch is carved and then buried in the soil, and after rooting, it is cut into new plants.

Aerial beading. Created by China, it is also known as Chinese stripping or high pressure. It is suitable for tall or non-bendable plants, and is mostly used for precious tree species (camellia, osmanthus, longan, lychee, sapodilla, etc.).

Select 1-3 year-old branches, peel 2-4 cm in rings, scrape off the cambium layer or carve it longitudinally into a wound, wrap it in a plastic sheet, a bamboo tube on the side, a clay pot, etc., wrap it in the cut, tie it tightly, fill it with moss or fertile soil, water it often to moisturize, and cut it off into a new plant after rooting.

Strawberries can be grown in less than three weeks to get a lot of pots, so let's get started.

In addition to some species that are easy to produce adventitious roots, such as grapes, ivy, etc., which do not need to be pre-treated, most plants in order to promote the rooting of strip reproduction, generally carry out trauma treatment on the root part below the bud or branch before stripping, and then bury the treated part in the substrate. This kind of pre-treatment includes ring stripping, stranding, circumcision, etc., which is to cut off the downward loose channels for the synthesis of organic matter and auxin from the top leaves and branch end growth branches, so that these substances accumulate at the upper end of the treatment port to form a relatively high concentration area. Because the xylem of the shoot is connected to the mother plant, it can continue to receive a continuous supply of water and mineral nutrients, and the yellowing treatment caused by buried pressure causes adventitious roots to occur at the incision like cuttings and roots. ‍‍

Strip propagation refers to the propagation method of pressing the branches into the Qisheng clear soil without detaching from the mother plant, promoting the rooting of the pressed parts, and then cutting off the mother body to cultivate independent plants. For tree species that are not easy to take root by cuttings, the propagation effect of the strip pressing method is better, and the disadvantage of strip propagation is that the reproduction coefficient is low. According to the part where the strip takes root, there are two kinds of strip propagation methods: ground strip and air strip.
