The latest culture method of Baolian flower

Baolinhua, also known as Pearl Pagoda, Baolian Lantern, Mei Ding Hua, etc., is native to the tropical forests of Philippines, Malaysia and Indonesia. There are also 15 species in China, which are produced in the tropical and subtropical rain forests of Hainan Island and southern Yunnan. Potted Baolinhua is most suitable for hotels, halls, shopping mall windows and villa guest rooms. Let's take a look at the breeding methods of Baolianhua.

Sowing and propagation of Baolian flower

1. Seed selection: first of all, seeds should be selected before sowing. Whether the seeds are good or not is directly related to the success of sowing. It is best to choose the seeds harvested in the same year. The longer the seeds are preserved, the lower the germination rate is. We should also choose seeds that are full, without imperfections or deformities, and seeds without diseases and insect pests.

2. Disinfection: disinfection includes two concepts, one refers to the disinfection of seeds, and the other refers to the disinfection of sowing substrate. Families usually soak the seeds in hot water for about 60 ℃ for a quarter of an hour, and then use warm hot water to accelerate germination for 12 to 24 hours. The best way to disinfect the substrate used for sowing is to stir-fry it in a pan so that any diseases and insects can be scalded to death.

3. Sprouting: soak the seeds in warm hot water (the temperature is about the same as facial wash) for 12 to 24 hours until the seeds absorb water and expand. For common seeds that germinate easily, this work does not have to be done.

4. Sowing: for small seeds that are difficult to pick up with hands or other tools, you can wet one end of the toothpick with water, stick the seeds one by one on the surface of the matrix, cover the substrate 1 cm thick, and then put the seeding pot into the water, the depth of the water is 1x2cm 2 of the height of the flowerpot. For larger seeds that can be picked up by hand or other tools, put the seeds directly into the substrate and order them at a distance of 3 × 5 cm. After sowing, cover the substrate with a thickness of 2 to 3 times that of the seeds.

5. Management: after sowing in late autumn, early spring or winter, when you encounter a cold wave and low temperature, you can wrap the flowerpot with plastic film to keep warm and wet. After the seedlings are unearthed, the film should be opened in time, and the seedlings should be exposed to the sun before 9:30 in the morning or after 3:30 in the afternoon, otherwise the seedlings will grow very weak. After most of the seeds have come out, they need to plant seedlings properly. When most of the seedlings have three or more leaves, they can be transplanted.

Cutting Propagation of Baolian Flower

1. Substrate: family cuttage is difficult to get ideal cutting substrate due to limited conditions. It is recommended to use the prepared and sterilized cutting substrate provided by this site. Medium and coarse river sand is also fine, but rinse with clean water several times before use. Do not use sea sand and river sand in saline-alkali areas, they are not suitable for the growth of flowers and plants.

2. Cuttings: when the softwood cuttings are carried out, the sturdy branches of the current year are selected as cuttings when the plants are growing vigorously from the end of spring to early autumn. After cutting off the branches, select the sturdy parts and cut them into segments 5-15 cm long, each with more than 3 leaf nodes. When hardwood cuttings are carried out, after the temperature rises in early spring, the robust branches of the previous year are selected as cuttings. Each cuttage usually retains 3-4 nodes, and the cutting method is the same as that of softwood cuttings.

3. Temperature: the optimum temperature for rooting of cuttings is 20: 30 ℃. It is difficult and slow for cuttings to root below 20 ℃. The upper and lower cuttings above 30 ℃ are easy to rot by bacteria, and the higher the temperature is, the greater the proportion of rot is. When there is a low temperature after cutting, the main measure of heat preservation is to wrap the flowerpots or containers used for cutting with thin film.

4. Humidity: the relative humidity of the air must be kept at 75-85% after cutting. The basic requirement for cuttings to take root is to ensure that fresh cuttings can cooperate with light to produce rooting substances before they take root, but cuttings without rooting can not absorb enough water to maintain their water balance. therefore, the water evaporation of cuttings must be reduced by spraying.

5. Light: cutting propagation is inseparable from sunlight, because cuttings have to continue to carry out photosynthesis to produce nutrients and rooting materials to supply their rooting needs. However, the stronger the light, the higher the temperature in the cuttings, the more exuberant transpiration of cuttings, and the more water consumed, which is not conducive to the survival of cuttings. Therefore, it is necessary to cover 50% to 80% of the sun after cutting, and then gradually remove the shading net after the root system grows.

The Culture method of Baolian Flower

1. On the pot: when the small seedlings are installed in the pot or the large plants that have been cultivated for several years turn to the basin, first put a coarse-grained matrix 2cm thick in the bottom of the basin as a filter layer, sprinkle a layer of fully mature organic fertilizer as base fertilizer with a thickness of about 1cm, then cover it with a thin layer of matrix, which is about 1cm thick, and then put in the plant to separate the fertilizer from the root system to avoid root burning, and pour water once after the basin. And keep it in a shaded environment for a week.

2. Humidity: Baolianhua likes the humid climate environment, which requires that the air relative temperature of the growing environment is 70-80%, the air relative humidity is too low, the lower leaves are yellowing and falling off, and the upper leaves are not glossy.

3. Temperature: Baolian is native to the tropics and likes the environment of high temperature and humidity, so it is very strict to the temperature in winter. When the ambient temperature is below 10 ℃, it can't survive the winter safely when the frost occurs.

4. Lighting: Baolianhua likes the semi-shaded environment and can give sufficient sunlight in autumn, winter and spring, but it should be shaded by more than 50% in summer and put it in a place with bright light when it is maintained indoors.

5. Fertilizer and water: for potted lotus plants, in addition to adding organic fertilizer when potting, proper fertilizer and water management should be carried out in the usual maintenance process.

6. Pruning: when the plant enters dormancy or semi-dormancy period in winter, the branches such as emaciation, disease and insect, withered and overdense should be cut off. The branches can also be arranged in combination with cuttings.

7. Change the basin: as long as the lotus is properly maintained, it will grow very fast. when it grows to a certain size, we should consider changing it to a larger basin so that it can continue to grow vigorously.

8. Diseases and insect pests: Baolian sometimes has leaf spot and stem rot, which is sprayed with 1000 times of methyl topiramate wettable powder. Pests are harmful to whiteflies and scale insects and can be sprayed with 1000 times of 50% dichlorvos EC.
