The latest culture method 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 outside after 4 pm and indoors before 9 am, so that it can 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.
