Methods of cutting propagation and matters needing attention in culture of longevity flowers

Longevity flowers are mostly propagated by cutting methods, and there are two cutting methods: leaf cutting and terminal bud cutting, general leaf cutting and tissue culture are mostly used for the production of female parent seedlings, and terminal bud cutting is mostly used for potted flower production. Let's take a look at the cutting propagation methods of longevity flowers.

Cutting methods of longevity flowers

1, leaf cutting: pick the whole leaf (the bigger the better), put it in a cool place to dry the wound, after a few hours, the petiole is completely inserted into the moist matrix, such as the petiole is too short, you can also insert a part of the leaf into the matrix to replace the short petiole, this stage is not too wet, so as to prevent the leaf from getting sick and rot, after cutting, put it in a weaker place in the sun and keep the temperature between 20: 25 ℃. The root system begins to be established after 4 weeks, when it can be put under full-day sunshine and low concentration of fertilizer can be applied. The seedlings differentiated from callus can be seen after 7 weeks and 10 weeks. When the seedlings reach 15~20cm, they can be separated from the leaves and cultured alone, while the leaves can continue to produce seedlings. Separate seedlings can be used as maternal seedlings for the production of rootless cuttings.

2. Terminal bud cuttage: insert the prepared rootless cuttings directly into the flowerpot with the substrate to keep the substrate moist. The matrix is generally mixed with peat and perlite in the ratio of 7 ∶ 3, and the pH of the matrix is adjusted to between 5.5 and 6.0. Producers can adjust the proportion according to their own water quality, production variety and production season, or add soilless substrates such as vermiculite and sand to achieve a matrix with good drainage and moderate nutrients. In addition, the light intensity should not be too strong, keep the temperature between 20-25 ℃, about 2-3 weeks can take root, and then enter the production period management. Terminal bud cuttings are generally used for potted flower production (note: longevity flowers are typical plants that bloom in long days, sunshine time must be longer than 12.5 hours during cutting propagation, and light must be replenished when cutting propagation in winter).

Cutting methods of longevity flowers

1. Cutting time: the leaf cutting of longevity flowers can be carried out all year round, but it is better in summer and autumn. Before cutting, prepare the cutting bed first, and the cutting substrate is fine river sand or sandy loam with good drainage.

2. Cutting method: the second day after longevity flower cutting, 0.1% sucrose and urea mixture was sprayed to the cuttings. As the longevity flower is a succulent plant with high water content, it should not be watered too frequently and the substrate is too wet, which is easy to cause root rot, which is usually watered every 2 to 3 days. Be careful not to get caught in the rain on rainy days. After about half a month, it can take root, and after 3-4 weeks, the calli at the base of the petiole can grow small tiller buds. After the tiller buds are unearthed, 0.2% potassium dihydrogen phosphate and sucrose mixture is sprayed once.

3. Management after insertion: 0.5% foliar nutrient solution of flowers is sprayed every 10 days, and one and a half months later, it can be planted in a pot. The basin soil should be well drained, loose and fertile sandy loam. After being put on the basin, it should be watered every 2-3 days. If the temperature is lower than 5 °C in winter, move people indoors to survive the winter.

Matters needing attention in the culture of longevity flowers

1, the temperature is suitable: the longevity flower likes the warm environment, too cold or too hot is not conducive to its growth, in the day its temperature is not more than 30 degrees, and at night it is not less than 18 degrees, the temperature is too high or too low will cause it to be dormant, that is, stop growing. Therefore, when raising longevity flowers, you should avoid exposure to the sun in summer, and keep them indoors in winter to avoid freezing.

2. Sufficient water: the longevity flower is a drought-tolerant plant, and its demand for water is relatively low. It only needs to be watered twice a week. It should be noted that if you have watered it at noon, then be sure to keep the leaves of the longevity flower dry before night.

3. Plenty of sunshine: longevity flowers prefer to grow in a sunny environment. If they are kept in a shady environment for a long time, they cannot carry out normal photosynthesis and cannot grow normally. At the same time, it will lead to longevity flowers losing leaves or not blooming. Therefore, we can put it in a sunny place in general season, but avoid exposure to the sun in summer.

4. appropriate fertilization: any plant can not grow without the right amount of fertilizer, and the longevity flower is no exception. Only when it has sufficient nutrients can it grow normally. During the growth period of the longevity flower, we should fertilize it every two weeks. This will help to promote its growth needs.

Propagation methods of longevity flower cuttings points for attention

Longevity flowers are low and green all the year round. They can be planted in spring, summer and autumn. Longevity has a long flowering period, luxuriant flowers and high ornamental value. Today, Xiaoqi would like to share the propagation methods and points for attention of longevity flower cuttings.

I. methods of cutting and propagation of longevity flowers

① leaf cutting will pick the whole leaf (the bigger the better), put it in a cool place to dry the wound, after a few hours, the petiole will be completely inserted into the moist matrix, such as petiole is too short, you can also insert part of the leaf into the matrix to replace the short petiole, this stage can not be too wet, so as to avoid leaf disease and decay, after cutting, put it in a weaker place in the sun, keeping the temperature between 20: 25 ℃. The root system begins to be established after 4 weeks, when it can be put under full-day sunshine and low concentration of fertilizer can be applied. The seedlings differentiated from callus can be seen after 7 weeks and 10 weeks. When the seedlings reach 15~20cm, they can be separated from the leaves and cultured alone, while the leaves can continue to produce seedlings. Separate seedlings can be used as maternal seedlings for the production of rootless cuttings.

② terminal bud cuttings directly insert the prepared rootless cuttings into the flowerpot with substrate, keep the substrate moist, the light intensity should not be too strong, keep the temperature between 20-25 ℃, it can take root in about 2-3 weeks, and then enter the production period management. Terminal bud cuttings are generally used in potted flower production. Longevity flowers mostly use the method of asexual reproduction, in addition to cutting, but also use tissue culture to propagate. Cutting can be divided into two kinds of cutting methods: leaf cutting and top bud cutting. Generally, leaf cutting and tissue culture are mostly used for the production of female parent seedlings, and apical branch cuttings are mostly used for potted flower production. In potted flower production, rootless cuttings are usually cut directly in the flowerpot where they will eventually be planted, so the cultivation medium and cutting substrate are the same, with the mixture of peat and perlite at the ratio of 7 ∶ 3, and the pH of the substrate is adjusted to 5.5 to 6.0. Producers can adjust the proportion according to their own water quality, production variety and production season, or add soilless substrates such as vermiculite and sand to achieve a matrix with good drainage and moderate nutrients.

Note: longevity flower is a typical long-day flowering plant, the sunshine time must be longer than 12.5 hours during cutting propagation, and replenish light when cutting propagation in winter.

II. Matters needing attention in cutting longevity flowers

1. Using net yellow sand, sandy loam or nutrient soil as medium, it is best to disinfect with 0.1% potassium permanganate solution.

2. If you pinch a branch that is 6cm long and 10cm long, you should have more than two leaf segments. When cutting longevity flowers, the cuttings should be cut as high as possible, and the lower end of the cut is generally oblique, preferably 2mm away from the bottom bud, which is conducive to rooting, and the upper mouth should be flat and more than 4mm away from the top bud. to avoid moisture loss after the upper incision dry and discoloration, resulting in cutting failure.

3. The longevity flower branch is inserted directly into the medium, and the insertion depth is 1 to 2, compacted and watered once. After that, keep the medium moist. Do not water or spray too much, as it will easily cause succulent leaves and stems to rot.

4. After cutting, longevity flowers can be covered with plastic film to keep heat and moisture, which can promote the rapid rooting of branches and ensure the survival rate.

5. The cuttings of longevity flowers should avoid strong light, and the cuttings should not be fertilized after cutting under the condition of scattered light.

6. the longevity flower cuttings are cut and live, and they can take root in about a week. After new axillary buds and leaves grow, they can be transplanted.

The above is the longevity flower cutting propagation content sharing, there are breeding longevity flower friends can try cutting propagation, oh, hope to be helpful to everyone.

Cutting methods and matters needing attention of longevity flowers in summer the culture of longevity flowers is relatively simple, and the flowers are beautiful, so they are very suitable for ornamental plants. Longevity flowers belong to succulent plants, and seeds can be selected for reproduction, but longevity flowers generally carry out asexual reproduction, and its propagation process is mainly completed by cutting. Longevity flowers bear less fruit, generally choose cutting methods when propagation, longevity flowers can be divided into two cutting methods: leaf cutting and terminal bud cutting. 1. The cutting method of longevity flower is leaf cutting. First of all, choose the healthy leaves that grow well, take off the whole leaves, and leave them in a cool place until the wound dries. Insert a part of the petiole of the treated leaf into a moist substrate and place it in a semi-shady environment, waiting for the leaf to take root and sprout. 2. The cutting method of longevity flower: terminal bud cutting. The apical buds of the prepared branches as cuttings were directly inserted into the flowerpot equipped with the substrate to keep the substrate moist, the light intensity should not be too strong, and it could take root after 2-3 weeks. This method is often used in potted flower production. Note: although the cutting of longevity flowers can be carried out throughout the year, it is better in summer and autumn. On the choice of cuttings with fine river sand or well-drained soil, even branches without leaves can survive; for flowering longevity flowers, you have to wait until the flowers have faded, subtract the residual flowers before cutting. In the process of longevity flower cutting, the substrate should not be too wet, the watering should not be too frequent, and the amount of water should not be too large, otherwise it is easy to cause root rot and so on. The cuttings of longevity flowers should be kept at room temperature of 20-25 ℃.
