Propagation methods of Milan Flower

Milan uses high pressure and cutting methods to propagate Milan flowers. High-pressure propagation should select 1-year-old 2-year-old strong branches from May to August and then wrap them with moss, wet soil and vermiculite when the incision is slightly dry, fasten it up and down with plastic film, and cut off the basin or transplant after taking root for 50 years and 100 days. The first ten days of June is the most suitable period for high pressure propagation, which can heal and take root quickly, and can blossom for 1 or 2 times in the same year.

Some of the leaves will turn yellow when propagated by high pressure method. This is a sign that the ring peeling site has healed and began to take root. It shows that the "high pressure" part has gradually separated from the mother and entered the period of sprouting new roots, due to too little soil in the plastic film and insufficient nutrient supply, this yellowing phenomenon is temporary, and after a period of time, it can be seen that the tender roots in the plastic film are gradually elongating, and then they can be cut off and planted separately.

It is easy and easy to propagate Milan by cutting, and there are a large number of them. Generally, the old wood cuttings were carried out every other year from April to September, and the same year tender wood cuttings were used from June to August. Choose a strong, full, growing branch, 10 cm to 12 cm long, and cut it off from the node. The cuttings of softwood cuttings should have 2 cm long old branches of the next year. Remove the leaves at the lower end of the cuttings, leaving only the upper 2-5 leaves to reduce water evaporation. Cut the incision and use river sand, perlite or well-drained loess as cutting soil. The insertion depth of the cuttings should be the length of the cuttings, which is 1 / 3, 1 / 2.

When cutting, first make holes with flat-pointed bamboo chopsticks, then insert the cuttings and press the soil with your hands to make the cuttings closely combine with the soil. After inserting, spray water with a small hole spray can, or put the basin in a shallow basin filled with water, until the soil is wet and take out. Cover with plastic film. Conditional use of full-light automatic spray plug-in machine. Soaking in 50 mg / L naphthylacetic acid solution for 15 hours before cutting is beneficial to rooting. 50-60 days after cutting, the branches are not withered and the leaves change to tender green, indicating that the cuttings have taken root and survived, and can be transplanted after the buds grow 3-4 cm.

The Propagation method of how to cultivate Milan Flower

Milan flower is a small ornamental tree, is a very special species. What do you need to know if you want to grow a good Milan? Let's take a look at the breeding methods of Milan flowers.

Propagation methods of Milan Flower

Breeding Milan generally breeds Milan better in the summer rainy season, so when the temperature is high and the humidity is high, breeding is easy to survive. Milan's reproduction methods can generally be divided into three types: pressing, high pressure and cutting, mainly cutting and high pressure.

Cutting method

It is easy and easy to propagate Milan by cutting, and there are a large number of them. There are two cutting methods in Milan: one is the old wood cutting of the first year, the old wood cutting time can be carried out between April and May, and the other is the tender wood cutting of the same year, which can be carried out between June and July.

The selection of cuttings, whether it is the old branches of the other year or the twigs of the same year, should choose the branches with strong, substantial and good growth potential as cuttings.

Softwood cuttings are usually harvested from June to July every year. Select the branches that grew strongly in that year, cut them into about 10 cm long, cut off the leaves below, and leave 2 Mel 3 leaflets at the top. It is best to soak with vitamin B12 injection before insertion to promote rooting.

Cuttings use flowerpots as cutting beds, vermiculite or river sand as cutting substrates with a depth of 4-5 cm, compacted and watered thoroughly after cutting, and covered with plastic film, requiring high temperature and humidity, temperature 28-30C, and then spraying water 2-3 times a day. Keep the soil layer moist and take root in 40-50 days.

High crimping method

The high pressure method should be carried out under the condition of high temperature and high humidity. The time of striping is generally between May and August, and the rainy season in early June is the best, with high survival rate and fast rooting. Because during this period, the environmental humidity is relatively high. Practice has proved that the high pressure from this period will take root one after another after 40 days, and if it is properly maintained in October, it can blossom twice. It is OK to start high pressure in July, but at this time it is the time of hot summer, when the sun is fierce, the water evaporates quickly, the environment is dry, the branches and leaves under high pressure are easy to scorch, and the roots heal more slowly. Therefore, after high pressure, it is necessary to put the potted mother Milan in a half-yin and half-sun or half-sun place, otherwise it is easy to scorch.

For the selection of high pressure parts, without affecting the shape of the whole mother plant, the sturdy branches that grow in alternate years and lignified should be selected, and the leaves should be removed and the ring peeling should be carried out at the length of 15ml / 25cm.

The high position pressing strip selects the sturdy and pest-free branches that are semi-lignified in the current year, more than 0.5 cm in diameter, 7-8 cm ring peeling below the branch point, wrapped in the ring with mud lump or wet vermiculite and moss, and wrapped tightly with plastic film, leaving mouth for watering, often keep moist, take root after 2-3 months, can be cut from the mother plant on the pot, easy to bloom.

The high position pressing bar can be divided into sleeve basin type and cladding type.

① pot type: choose the sturdy branches that have been wooded in one year, and cover the flowerpots with enlarged pots at the bottom of the pots to make the flowerpots stable. Peel the Milan branches 1 cm wide on the Milan branches in the flowerpot, then fill them with soil and water them thoroughly, and water them every day after that, always keep the soil wet. Generally, it can take root in two months, cut off the mother plant and cultivate it separately.

② cladding type: select annual Lignified robust branches, about 10 cm away from the base of the branches, for circular peeling, leaving 4-5 twigs in the upper part, and all the lower lateral branches are cut off, with pre-prepared soil (mixed with fertile soil and moss drunken; drying on the stove, and then kneaded with boiling water, cool thoroughly) wrapped in the peeling place, wrapped in plastic enzyme film, fastened with thread, the lower part does not make it leak, the upper part is slightly loose, easy for water injection. The dressing part should be 10 cm long and 5 cm in diameter. In the future, water should be injected into the dressing place every day to keep it moist. It can take root in two months, cut off the mother plant and plant it separately.

Culture methods of Milan flower

Rice orchid is a kind of evergreen shrub, small tree, alias Magnolia, rice orchid, tree orchid, fish orchid and so on. Milan is native to Fujian, Guangdong, Guangxi, Yunnan and other provinces of China, and it is also distributed in Southeast Asia. It is a common fragrant ornamental plant. Now the editor of Qiannong Network will take a look at the breeding methods of Milan with you.

Growth habits of Milan Flower

Milan flowers prefer warm, humid and sunny environment, not cold-resistant, slightly shade-tolerant, the soil is the best in loose and fertile slightly acidic soil, and the winter temperature is not lower than 10 ℃.

1. Milan flowers like to be warm, sunny and fat. The suitable temperature for growth is 20 ℃ ~ 25 ℃. Under normal circumstances, when there is plenty of sunshine and a high temperature (about 30 ℃), the flowers will have a strong fragrance. If it is placed in shade in summer and a large amount of nitrogen fertilizer is applied at the same time, it is one of the main reasons why Milan flowers do not blossom or blossom less and have a light fragrance. Therefore, during the period of growth and development, Milan flowers need to be maintained in a sunny place outdoors, and should pay attention to applying more liquid fertilizer containing more phosphorus, preferably with crushed bones, fish bones, chicken bones, etc., often supplemented with chemical fertilizer containing more phosphorus or fermented rice water, which is helpful to pregnant buds, and blossoms more, golden in color, and fragrance.

2. Milan flowers like to be moist and should be watered properly during their growth. If too much watering, easy to lead to rotten roots, leaves withered off; flowering period too much watering, easy to cause falling flowers and buds; watering too little, it will cause leaf edge withered, withered buds. Therefore, when the summer temperature is high, in addition to watering water 1 / 2 times a day, branches and leaves are often sprayed with clean water and sprinkled to the ground to improve air humidity. At the same time, fertilization should also be appropriate. As Milan blossoms more often in a year, after each blossom, it should be fertilized with 2 or 3 fully mature thin liquid fertilizer in time, so that it can blossom continuously and have a strong aroma. Milan flower likes acid soil, so it is suitable to choose rotten leaf soil as the main culture soil in pot cultivation. During the peak growth period, 0.2% ferrous sulfate solution is sprayed once a week, and the leaves are green and flowers are numerous.

Propagation techniques of Milan Flower

Rice flowers are commonly used for cuttage and high-altitude striping propagation.

The main results are as follows: 1. there are old branch cutting and tender wood cutting. the former uses the old branches of last year as cuttings from April to May, while the latter selects semi-lignified branches of the same year from June to August. The standard of collecting tender cuttings is that the leaves at the end of the branches are thick, the color is green, and the axillary buds are full. The cuttings are about 10 cm long, the upper 2-3 leaves are retained, and all other leaves are removed to reduce water evaporation and nutrient consumption and flatten the incision. Cutting media can use river sand, expanded perlite, peat, vermiculite and so on. When cutting, you can first use bamboo chopsticks to drill holes in the soil, the spacing is about 5 cm, and then insert the cuttings into the hole, the depth is about 1x3 of the cuttings. After insertion, use your fingers to compact the soil, so that the soil and cuttings are closely combined, and fully watered. Set up a shade shed to maintain a ventilated and moist environment. The speed of rooting of cuttings is closely related to the soil temperature. When the bottom temperature is high, the rooting is fast. When the base temperature is 30C~32 C, it can take root 40 days after cutting, and it takes 50-60 days for 25 C to take root. However, the bottom temperature is high, the leaf evaporates quickly, and the metabolism of cuttings is in an active state. At this time, if the humidity is low, it is easy to cause the cuttings to fall leaves. Once the cuttings are defoliated, there is no hope of survival. Therefore, high temperature must also ensure high humidity, usually maintaining a relative humidity of more than 85%. Before cuttage, the base of cuttings was soaked in vermiculebutyric acid of 20PPm~25PPm for 12 hours, or indole acetic acid of 50PPm for 15 hours, which could promote rooting.

2. High-altitude pressing can be done from May to September, but the best time is the Meiyu weather in June, when the survival rate of high pressure is high and takes root quickly. generally, Milan flowers with high pressure in the first ten days of June can take root one after another after 40 days. The specific method is: select annual Lignification sturdy branches, stem diameter 0.5 mm. Make a circular peeling 20 cm away from the bifurcation, the width of the ring is about 0.5 cm, and the depth is to see the xylem, then apply it to the ringed part with moss or wet soil, and then wrap it with plastic film to keep the moss moist all the time. After taking root, cut away from the mother, first slow the seedling in the shade place, and then plant it in the basin. By using this method, the survival rate is high, and the mature seedlings bloom quickly.

Cultivation and Management of Milan Flower

Although the Milan flower has strong shade tolerance, it is not resistant to long shade, especially when the potted rice flower is in full bloom, it can not be placed indoors for a long time. When it blossoms, it can be moved outdoors after 4: 00 p. M. and indoors before 9: 00 a. M. to make it accept sunlight and accumulate nutrients for the emergence of new branches and new flowers. When moving indoors in winter, you should also make it receive as much light as possible.

Although the requirement of Milan flower on soil is not strict, it is suitable for sandy loam which is rich in humus, fertile and slightly acidic. When preparing basin soil, 2 parts of peat soil, 1 part of Gaza, 2 parts of fertile garden soil, 2 parts of compost soil and 1 part of Gaza were mixed. After the seedlings are in the pot, when they grow to 20 cm ~ 25 cm high, the heart can be removed to promote the formation of lateral branches and the formation of a crown as soon as possible. at the same time, the plant height can be controlled and the number of flowers can be increased.

When planting flowerpots in Milan, it is necessary to ensure good drainage and watering according to the dry and wet climate, not only to keep the pot soil moist but not to have too much water for a long time. Maintaining high air humidity is beneficial to the growth of Milan flowers, and it is best to spray water on the leaves once or twice a day in the period of drought and vigorous growth.

The Milan flower has luxuriant branches and leaves, and during the growing period, it constantly produces new branches and forms spikes, so it needs sufficient fertilizer. If the fertility is not enough, the amount of flowers will decrease significantly. To this end, after the spring begins to grow, fertilizer should be topdressing in time. Topdressing with rotten cake fertilizer or sesame sauce residue water is better, Milan flowers can not stand thick fertilizer, so fertilization should grasp the principle of frequent application of thin fertilizer, especially when topdressing in spring, do not apply thick fertilizer. Topdressing should be applied once every 10 days, and an appropriate amount of calcium superphosphate should be added in fertilizer and water.

When it is hot in summer, to put the Milan flowers in a shady place, you can put them on the edge of the shade shed, so that you can not be exposed to strong light and get more sunshine. Because too strong direct light has an inhibitory effect on the growth and development of Milan flowers, and too shaded, it is also easy to cause Milan flowers to grow, grow weak and reduce the number of flowers.

According to the temperature requirements of Milan flowers, potted Milan flowers generally can not be moved outdoors until Grain Rain, but in autumn they have to move indoors before Frosts Descent to spend the winter. During the overwintering period, it is suitable to keep the room temperature at 10C~12 C. too high room temperature is easy to cause continued growth, which is disadvantageous to the growth and development in the second year. However, when the temperature is too low and falls below 5C, it is easy to cause frost damage. Milan flowers spend the winter indoors, the leaves are easily stained with dust, affecting its normal photosynthesis, so every once in a while, it needs to be washed.

Plastic surgery should be carried out from the beginning of the seedling to retain a section of the trunk 15 cm ~ 20 cm high, and do not let the main branches come out from the ground. Because Milan flowers produce spikes in the armpits of new leaves, they are generally not pruned. In order to control the shape of the tree and add new branches, you can pick the heart before the new branches grow, or prune them in combination with cuttings.
