Strip propagation

Layering propagation is to press the branches on the mother plant into the soil, take root, and then separate the new branches from the mother plant to form an independent new plant. Layering is divided into low-pressure propagation and high-pressure propagation

Low pressure reproduction

Low pressure propagation is to directly bend and press the branches into the soil and wait for rooting. It is generally applicable to plants with branches close to the ground and easy to bend, such as rose, chrysanthemum, Campanula, cherry, etc

Breeding techniques:

1. Select 1 ~ 2-year-old branches, cut the lower part, and then press them into the soil horizontally or bending, fix and bury them to keep the soil moist

2. After rooting, it can mature and break into independent plants in about one or two months

High pressure reproduction

High pressure propagation is suitable for plants with high branches off the ground, not easy to bend and difficult cutting, such as camellia, trigonometry plum, litchi, white orchid, etc

Breeding techniques:

1. 2-year-old healthy branches without diseases and pests shall be selected for layering; Peel 1 ~ 2cm wide annular skin at 2 ~ 3mm under the axillary bud, and then apply IBA auxin

2. Wrap a few circles of plastic film 3 ~ 5cm below the wound, then go up backwards, fill it with wet moss, peat soil or sawdust, seal the upper mouth and leave enough space; Replenish water and light will soon take root

Cutting propagation

Cutting is to select a part of plant organs to cultivate. The more suitable flowers are green rose, ivy, crab claw, hydrangea, rose, peony and so on. Huahua, take green pineapple as an example

Cutting skills

1. Select semi lignified branches with air roots, about 10cm long, the lower cut is inclined by 45 degrees, and a leaf is reserved at the top of the cuttings

2. Put the cuttings into the mixed soil of sandy soil and perlite, pour water through it, and then put them in a cool and astigmatic place to keep ventilation

3. Water once every three days to keep the soil moist, take root in about 20 days, and maintain it normally after half a month

Grafting propagation

Grafting is divided into scion and rootstock. What is grafted is rootstock. Scion is generally divided into branch grafting and bud grafting. Suitable grafts in summer include wild rose and rose grafting, red maple and green maple grafting, camellia and Camellia grafting. Take rose as an example

Reproductive skills

1. Cut several sections of 10 cm or so, disease-free rose branches as rootstocks, and remove all leaves and bud points; Then cut a newly flowering semi lignified rose branch for cuttings

2. Cutting interface: cut a 3cm long interface from top to bottom on the rose rootstock

3. Select the rose leaf bud with full bud point as the bud grafting, and then cut a bud grafting incision whose size is just consistent with the rootstock incision

4. Insert the bud into the interface of rose rootstock, align both sides, and wrap the grafting part tightly with transparent plastic film to expose the bud point, but the bud will not move

5. After successful grafting, the branches are transplanted into loose and fertile soil and maintained in an astigmatic and ventilated place. After about 10 days, the grafted buds can grow significantly

Ramet propagation

Ramet, in fact, is to separate the cluster branches of flowers from the mother plant and cultivate them separately. Money tree, orchid, peony, asparagus, Clivia and so on are all suitable for ramet propagation. Now Huahua will introduce the ramet propagation of Clivia to you

Reproductive skills

1. After the flower of Junzi orchid is withered, 5 ~ 6 time plants will grow from the seed buds. The soil medium and scissors should be disinfected before branching

2. Take out the mother plant from the basin, gently shake and peel off the soil without damaging the root system, and then cut the mother plant and the new plant short and separate with scissors

3. After branching, apply plant ash or charcoal powder on the wound to prevent infection with diseases and pests

4. After drying, transplant the root tip of the new plant downward into the mixed soil of vermiculite and perlite, keep the soil moist and breathable, and put it in a cool place for normal maintenance for half a month

Seed reproduction

Generally, annual grasses and flowers are more suitable for seed reproduction, with fast flowering speed, such as Petunia, purple jasmine, sunflower, Scutellaria barbata, cornflower, etc. today, let's introduce the sowing and reproduction of purple jasmine

Reproductive skills

1. Ordinary garden soil mixed with a small amount of sand, stone and plant ash shall be used to pour water, and then the seeds shall be evenly sown in the soil, covered with a layer of thin soil, sprayed with water in time to keep it moist, and germinate after about a week

2. After 3 ~ 4 weeks of emergence, the seedlings shall be planted in a large basin. The basin soil shall be mixed with humus soil, compost soil and sandy soil in the proportion of 3:3:4. Water shall be poured every 2 ~ 3 days and placed in the astigmatism place for normal management

Today Huahua will teach you all five breeding techniques

Dear flower friends, have you learned it
