Breeding methods and matters needing attention of Song Mei (Chunlan Song Mei)

Song Lan is native to central and southern China. Like cool, moist and ventilated, avoid extreme heat, dryness and direct sunlight. The soil is required to be well drained, rich in humus and slightly acidic. The north should be cultivated in a greenhouse in winter with a minimum temperature of not less than 5 degrees Celsius. Song Mei is very easy to grow, but it takes a lot of work to have good flowers. The grass is too weak. It's too fat to open a plum valve. Medium seedlings are easy to open plum petals. For this reason, the use of fertilizer and water in management should be properly controlled. It is said that if you want to open plum daffodils and double flowers, it is necessary to develop her into a very strong seedling, you need to increase the amount of water and fertilizer, you can get what you want.

Breeding technology

Ramets are often used in Songmei breeding. Once in 4 ~ 5 years. The ramet time is mostly carried out before the new bud is exposed, or before winter after flowering. Let the basin soil dry, shake off the soil, and cut off the old roots and some old leaves before dividing the plants. Cover the bottom hole with small tiles, add crushed bricks and coarse sand to each layer, and the thickness is 1 / 5 of that of the flowerpot; then put the new buds outward, spread the roots and place them in the pot, cultivate the soil and gently shake the flowerpot to make the soil tight, slightly raise the seedlings, and then add a layer of culture soil. Finally, water it in a cool place and move it to semi-shade after 1-2 weeks.

Management technology

Potted Songmei was planted with 4-6 plants in each pot, and the orchid seedlings were symmetrical, distributed reasonably and filled into the soil cautiously. Pour water into the basin and place it in a place where there is no direct sunlight and shelter from the wind. After a week, it can be moved in the shadow of the balcony, and then gradually see the light. The culture soil is often mixed with rotten leaf soil, sand, dry cow dung (4:1:1) or peat soil, sand and dried cow dung (3:1:1). Use oil residue and chicken manure as base fertilizer. Thin manure water was used for topdressing, once a week from May to August. If the scape of Song plum is too much, it can be thinned and each clump can have a branch of flower. It is the northern wind season after flowering, so it is necessary to prevent the dry wind from blowing, protect it with plastic film and irrigate the water properly. Watering less before changing pots, killing insects, overcast and rainy days; small plants and less watering of leaves with black spots. Songmei has many diseases and insect pests, so attention should be paid to prevention and control.

After the Song plum blossoms, it is appropriate to rest, sunny, suitable for water, so that the flowers can be as proud as spring, round and pleasant.

Culture methods and matters needing attention of Chunlan Song Mei

Chunlan Songmei is a kind of orchid, it is a unique plum petal orchid, has been cultivated in China for hundreds of years, is a fine orchid. Chunlan Songmei has a lot of things to pay attention to when raising Chunlan Songmei. Then I will specifically say for you that friends who like to breed Chunlan Songmei can take a look.

Culture methods and matters needing attention of Chunlan Song Mei

1. Flowerpots and potted soil of Chunlan and Song Mei

At ordinary times, when raising Chunlan and Song Mei, you should choose a high bucket mud basin, which should not be too large, as long as it can stretch its roots. The selection of basin soil must meet the requirements of air permeability, water leaching and complete nutrients, and the most important choice is the slightly acidic soil with high humus content.

2. The lighting requirements of Chunlan and Song Mei.

Chunlan Songmei has a high demand for sunlight during its growth, and the early sun is the most conducive to its formation, which is also the main factor affecting its flowering, so it is usually best to put Chunlan Songmei in a place with morning light. Receiving sunlight for two to three hours a day is most conducive to its growth and will make it blossom year after year.

3. Chunlan Song Mei should be ventilated and controlled by water during culture.

Chunlan Songmei must be in a ventilated environment when breeding, especially when it is muggy in summer, it should be moved to a cool and ventilated place, timely ventilation can speed up the photosynthesis of Songmei and reduce the occurrence of some diseases and insect pests. In addition, Chunlan Song Mei also has its own requirements for water, it likes wet soil, but watering can not be over-watered, to grasp the principle of dry watering, watering thoroughly, and can not be fixed at a certain time watering, should be flexible.

How to raise Chunlan Song Mei the breeding method of Chunlan Song Mei

Song Mei is a traditional inscription of Chunlan in China and a representative variety of plum petals. Its full name is Song Jinxuan Mei. Because the plum blossom products of Song Dynasty are unmatched and occupy the top position in Chunlan, it is chosen as the first of the "four Heavenly Kings" of Chunlan. It is also known as the King of Chunlan, which is of great ornamental value. Let's take a look at the breeding methods of Chunlan and Song Mei.

The growth habits of Song Mei

Song Mei is a horticultural variety and should be planted in a well-ventilated environment. Sex likes yin, avoid direct sunlight, like moist, avoid dryness, 15 ℃ to 30 ℃ is the most suitable for growth. The growth was poor above 35 ℃. The severe cold below 5 ℃ will affect its growth, and orchids are often dormant. If the temperature is too high and the sun is exposed, the leaves will burn or scorch within a day or two. If the temperature is too low and it is not transferred into the house in time, frostbite will occur. Chunlan Songmei is a fleshy root, which is suitable to use sandy loam rich in humus, and its drainage performance must be good. Humus leaf soil or mountain soil with more humus should be selected. For slightly acidic loose soil or iron-containing soil, the suitable pH value is 5.5-6.5.

The breeding method of Song Mei

1. Ramet: after one or two years of cultivation, Songmei can sprout many new buds. When the number of seedlings reaches 6 or 7 seedlings, it can be ramified, usually once every 2 or 3 years. In spring and autumn, select more than 6 or 7 plants, pick up the pot, gently pat the bottom of the basin, pour out the orchid root, be careful not to hurt the new root, brush the old soil on the root, find out the large gap between the false bulbs, break it carefully, trim the withered root and rotten root with scissors, then soak in 40% methyl thiophanate or chlorothalonil 800 times solution for 1 hour, then rinse with clean water and dry. It can be planted when the roots are white and soft.

2. Sowing: the Songmei seed is very fine, there is only one underdeveloped embryo in the seed, the germination power is very low, and the seed coat is not easy to absorb water, so it can not germinate by conventional sowing, so it is necessary to use orchid or artificial medium to supply nutrients to germinate. Sowing it is best to choose uncracked fruit, after the surface is sterilized with 75% alcohol, take out the seed, soak it with 10% sodium hypochlorite for 5 minutes, rinse it with sterile water for 3 times, sow it in a culture bottle containing culture medium, then place it in a dark culture room, keep the temperature about 25 ℃, germinate and move to light to form protocorm.

3. Tissue culture: first, cut 2cm growth buds from the roots of orchid plants cultivated for 2 or 3 years, rinse them with running water for 20 minutes, remove the outermost 1-2 bracts in a sterile tissue culture room with a temperature of 22-25 ℃, soak them in sodium hypochlorite solution for 15 minutes, and sterilize. Then peel, cut into 2-5 mm stem tip, inoculate on the prepared medium, move to the culture place, send out rhizome after 3-4 months, continue to proliferate, and then induce buds and roots. When the test-tube plantlets grow to 5-8 cm and have 2 or 3 roots, they can be transplanted.

The breeding method of Song Mei

1. Plant material: the preparation of nutritious plant material is the basis to promote the healthy growth and flowering of Songmei. You can use fine washed peat 25%, gold plant stone 20%, immortal soil 15%, willow bark 10%, snake wood 15%, Maifan stone 5%, brick 10%. This plant has the advantages of fast growth, healthy growth, good taste and strong aroma.

2. Selection of basin: song Mei's basin had better be a burning high bucket mud basin, or a sesame sand high bucket basin from Yixing, which is not easy to be too large, as long as Langen can stretch out in the basin. It is most suitable to raise about 6 seedlings in each pot, and the orchid plant should have a combination of old, middle and green plants, so that you can see flowers year after year. Remember to use the new pot with blisters (annealing) for more than 2 days, and the old pot to be washed and detoxified before use.

3. Illumination: the sun in the morning is most beneficial to the growth of Song Mei, and the sooner the better, the better. It is best to shine on the orchid plant as soon as the dawn appears. Because morning light is the main factor affecting the growth and flowering of orchids, orchids are most active in photosynthesis in the sun before 10:00 in the morning. Therefore, if there are conditions, it is best to put Song Mei in a place with morning light and shine for 2 to 3 hours a day, which is very conducive to growth and make it blossom every year.

4. Ventilation: a good ventilation environment is a necessary condition for raising Song Mei, and it is very important to put Song Mei in a good ventilation environment. Especially in the muggy weather in summer, Song Mei must be placed in a cool and ventilated place. In northern Henan, as long as it is safe, it can be said that raising orchids is half a success. Ventilation can provide fresh air to orchid plants, accelerate photosynthesis, reduce the occurrence of diseases and insect pests, and promote the growth and health of orchid plants.

5. Watering: watering is the key to the success or failure of raising Song Mei. The ancients said, "make friends, water the flowers and water the roots."Lan likes rain and fears accumulation, likes moistening but hates dampness, likes to dry but avoids dryness."

① should determine the amount of watering according to many factors, such as the size of the basin, the growth status of orchid plants, the ventilation condition, the thickness of plant material, the temperature and so on.

② watering can not be fixed time, should often observe the dry and wet situation of plant materials, grasp the timing of watering, dry watering, watering thoroughly.

The water temperature of ③ watering orchid should be the same as that in the orchid basin as far as possible, and the temperature difference should not be too large, especially in summer and winter.

④ year-round watering to use clean falling water (Rain Water, snow water), it is best not to use tap water, resolutely put an end to polluted water.
