Introduction of common propagation methods of leaf flower

Bougainvillea flower is particularly long, but due to the special geographical environment of our country, it will vary from place to place. If the temperature is suitable, Bougainvillea can bloom all year round. The horticultural varieties of Bougainvillea are also increasing with the development of Bougainvillea. Artificial propagation of Bougainvillea can be carried out by cutting, layering, water insertion and grafting.

1. Cutting propagation

5-6 In September, healthy 1-year-old branches were selected and cut into cuttings 10-15 cm long, leaving 4-6 bud eyes in each section. Choose new flowerpot, use vermiculite or plain sand as cuttage substrate, branch into the ground 4-6 cm deep, spray water, cover glass plate or cover plastic film moisture, put in semi-shady place or indoor sunny place, keep the temperature in the pot at about 24-30 degrees Celsius, if the temperature in the pot is too high, can move to the shade, generally after 15-30 days can take root. Usually pay attention to ventilation spray water, 40 days later can be on the basin. The seedlings that have just been potted are placed in the shade for 1 week, and then placed in a semi-shady place. After half a month, the light is increased. After 1 month, they can be managed as adult plants, and they can bloom in the second year.

II. Laying propagation

5-6 Month, select the lower part of the plant 1~2 years old branches, pressure into the pot. The branches pressed into the soil must be peeled in a ring shape, and their width should be more than twice the diameter of the branches. After pressing, they should be covered with soil and fixed. They should be kept moist by spraying water. They should take root for about 1 month. After more than 2 months, they can be cut off. The seedlings propagated by layering grow quickly and are suitable for family flower cultivation.

3. Water insertion propagation

Orange yellow, red, pink and other varieties of triangular flowers, water insertion method is more convenient. At the end of spring and early summer, cut annual branches from healthy plants, cut them to 15-20 cm long, with 3-4 nodes as cuttings, cut the lower part flat with a sharp knife, tie several roots into small handles with plastic rope (not too tight), wash and disinfect them with a jar, pour clean water, about 2/3 of the volume of the bottle, insert cuttings into 1/3 of the water depth, fix them with objects, wrap the bottle with black paper, do not let light penetrate, avoid wind, rain and sunlight, change water every morning and evening, Prevent wound decay, after about 15-20 days, cuttings can heal root. When the root grows to 1 cm, it should be on the pot. On the early pot to often water, so that the pot soil to keep moist, and in the shade of conservation, to be its germination after growth, into normal care.

IV. Grafting propagation

In the spring when the temperature is above 15 DEG C, 3-4-year-old common leaf flower is used as rootstock, and excellent varieties such as double petals are selected as scions, which are 5-10 cm long, and the cleavage method is adopted. After 40-50 days, they can heal and send out new buds.

Introduction to common propagation methods of spider orchid

Chlorophytum has been artificially cultivated for a long time, so after continuous improvement, the variety of chlorophytum is also increasing. The cultivation difficulty of spider orchid is not high, so many flower friends want to breed spider orchid themselves, the most commonly used way of spider orchid propagation is cutting propagation, this method of operation is relatively simple and the survival rate is relatively high. Xiaobian will introduce you to several common breeding methods of spider orchid, friends in need can learn together.

spider plant

1. Sowing

This method is less used, generally in March is more appropriate, sprinkle the spider seed, cover the 5mm soil layer, watering wet, can not have water, so as not to soak the seed in water, temperature control at 15 degrees is better, half a month can germinate.

II. Rite

It is troublesome to multiply by dividing plants. It is necessary to take out the plants of hanging orchids, strip them from the soil, and then cut new plants. It should be noted that the new plants must have stems and leaves in order to ensure the growth of plants.

III. Cutting

The simplest and most commonly used method, the survival rate is also relatively high, need to grow more vigorous, there are long buds of stolons, stolons cut down, directly inserted into the soil, a week can take root survival.

IV. Post-reproductive management

1. Change the basin and soil. In order to ensure that the stems and leaves grow luxuriantly, you can change the pots and soil one year, and remove the withered roots to ensure that the base fertilizer in the soil is sufficient.

2. Watering. Chlorophytum like wet environment, soil culture chlorophytum must ensure that the soil is wet, but the temperature is too low can not be too wet, otherwise it will frostbite plants. Sprinkle water regularly on the leaves to avoid excessive dust affecting growth and beauty.

3. Fertilization. Mainly nitrogen fertilizer, nitrogen fertilizer can be used for domestic ornamental plants in general, and fertilizer can be applied once a month, liquid fertilizer.

4. Light. Chlorophytum like damp, should avoid strong light exposure, can occasionally take out outdoor drying.

5. Temperature. Chlorophytum generally 15 degrees to 25 degrees grow well, 5 degrees below the plant will be frostbite.

Introduction to common breeding methods of Rieger Begonia

Rieger Begonia has a long flowering period and unique fragrance. It is a rare potted flower in greenhouse. After variety improvement, Rieger Begonia is very popular in Europe and America. Rieger Begonia more commonly used propagation method is cuttage method, can also be used for seeding and tissue culture methods of propagation, Xiaobian for you to introduce in detail the three propagation methods of Rieger Begonia.

Rieger Begonia

1. Cutting

Rieger Begonia can be inserted not only branches, but also leaves. When inserting branches, the length of branches should be moderate, and the lower part of branches should be cut into horseshoe shapes with blades; when inserting leaves, the leaves with vigorous growth and maturity should be selected, and the lower end of petioles should be obliquely cut with blades. Cutting substrate for vermiculite powder or sand, has been contaminated substrate to disinfect reuse. After the cuttings are inserted, water should be poured thoroughly, but no water should be accumulated on the leaves. And cover it with plastic film, put it in scattered light, properly ventilated, avoid high temperature. About 3 weeks cuttings can root.

When new leaves grow, they are rooted. The plants obtained by shoot insertion have no underground tubers. After 3 weeks, fibrous roots can grow out from the lower part of petiole, but it takes another month and a half to grow adventitious buds from the lower part of petiole and gradually emerge. Photo 2 is a plant grown with cuttings.

II. Sowing

Sowing: Because the seeds are very small, the small seed sowing method must be used. At present, Rieger Begonia seeds are basically imported, sub-coated particles and non-coated particles of two kinds. It is best to mail order the original packaging and undamaged seeds from large flower companies, so as to ensure germination into seedlings, bulk seeds are difficult to germinate.

2, sowing container, coated seeds can be sorted, can be used hole seedling tray, non-coated seeds can only be used seedling tray. The sowing substrate is peat soil and vermiculite powder respectively, which are crushed and disinfected, then mixed and stirred into a semi-wet state for later use. Because peat soil has water repellency in dry state, it cannot be used in dry state because it cannot be watered. When sowing, first put the substrate into the seedling tray, and then water it thoroughly with a watering can. Coated seeds can be sorted with tweezers, one for each hole, uncoated seeds can be mixed with appropriate amount of fine vermiculite powder and broadcast on seedling trays.

After sowing, there is no need to cover the soil, only spray with a fine spray can, and then use transparent plastic film to wrap the seedling tray. At ambient temperature of 20℃ or so, emergence began in about 12 days. When the seedlings grow true leaves, they can be properly ventilated to promote their roots. The sprouts grow slowly in three months. The seedlings sown in early summer do not need to remove the plastic film throughout the summer, and the seedlings are resistant to high humidity and high temperature.

After the beginning of autumn, the weather is cool, and the plastic film can be gradually removed to practice seedlings. By early winter, it can be potted. To use a smaller bottom porous flowerpot, culture soil can be used peat soil 2 and vermiculite powder 1 (or 1 with plain sand) mixed preparation, control watering before the pot, so that the culture soil in the seedling tray is in a semi-dry state, so that seedlings can not be scattered when the roots are damaged. Just on the pot of seedlings to prevent weather changes temperature is too high, at the same time to cover with plastic film, but not too tight, to properly ventilate, to prevent rotten seedlings.

Under family conditions, the first year does not grow into a large plant, but flowers can be seen, and the second year can be cultivated into a large plant. In the second year, you can change to a larger flowerpot.

III. Tissue culture

This is an effective way to obtain large numbers of flower seedlings quickly and successfully under family conditions. In the growth season, a large number of virus-free seedlings can be obtained by using well-developed leaves as explants in a certain culture medium through non-toxic explant culture, subculture and rooting culture. This method is expensive and is only used in mass production.
