The family propagation methods of Ranunculus japonicus are: bulb propagation, ramet propagation, seeding propagation and tissue culture propagation. When we raise Ranunculus japonicus at home, we usually use bulb to propagate.
The requirements for sowing and propagation are relatively high, which is more suitable for field planting and breeding, and for large-scale propagation of Ranunculus japonicus. Next, I will introduce the bulbous and ramet propagation methods of Ranunculus japonicus.
It can be said that the bulbous branch propagation method of Ranunculus japonicus is the most suitable method for family flower cultivation. The propagation in this way has the advantages of short growth cycle, early flowering, large flower plants, and many flowering. The biggest advantage is easy cultivation.
The disadvantages are also very obvious: the propagation coefficient of ramets is low, the propagation speed is slightly slow, and there is no way to mass production, so it is only suitable for domestic flower friends.
The best time of ramet propagation is from September to October. Take out the root block of Ranunculus japonicus which is dormant in summer, remove the soil and break it off according to the natural growth trend. Each piece should have a segment of root whisker and a number of new buds and small root pieces.
Put the root block into 1% potassium permanganate solution and soak it for 3-5 minutes to disinfect and exterminate the bacteria. Dry it slightly and plant it.
In order to prevent the root from rotting and sprouting neatly, the tuber roots of Ranunculus japonicus, which are dormant in the basin for summer, should be treated with sprouting after disinfection: select shade, ventilation and rain shelter, lay a layer of 5cm thick clean wet river sand, insert the tuber roots in the wet sand upside down, only bury the sprout parts, and the rest are exposed.
Spray cold water frequently to keep the river sand dry and free of water; spray 800 times of 50% doyinling wettable acne solution once a week for disinfection to prevent root rot.
After the tuber root slowly swells at low temperature, it will be planted when the buds sprout like rice grains and new roots are born about 20 days later. The planting should not be too deep, just bury the root neck.
Too deep is not good for leaves; too shallow is not good for roots. Control the watering before emergence, keep the soil moist, and gradually increase the watering amount after seedling preparation.
Raising seedlings:
The normal sowing time of Ranunculus japonicus is from the middle of October to the middle of November. After putting Ranunculus japonicus seeds into the water for a day, take them out, put them on gauze, wrap them up, and then put them in the incubator for germination. The temperature is about 15 ℃, take them out in the morning and evening every day, rinse them with water once respectively, and then drip the water to keep the seeds moist.
About 7 days after germination, some seeds began to germinate, at this time, they can be seeded immediately.
After the germinated seeds are properly dried, put a proper amount of yellow sand and mix well, and then sow them in a flowerpot or garden. Mix peat and perlite as 1:1, and the thickness is 0.2 ~ 0.3cm.
The planting and propagation of Ranunculus japonicus should choose the soil with good drainage and be carried out in the environment with good ventilation and light transmittance. Strengthen the protection of sowing environment to avoid the threat of weather disasters and diseases and insect pests.
It usually takes a week for seedlings to grow after sowing. At this time, it is necessary to keep the soil moist and replenish water in time to ensure the smooth emergence of seedlings.
When the seedlings of Ranunculus japonicus grow to 3-4 true leaves, they will be planted from mid December to mid January.
Ranunculus japonicus is fond of micro acid environment, so loose and fertile sandy loam should be selected.
Generally, garden soil, sandy soil and rotten cake fertilizer (chicken manure) are used to prepare the plants in the proportion of 5:3:1, or the same soil, rotten leaf soil and rotten organic fertilizer are used to prepare the plants in the proportion of 4:2:1. The spacing between the rows is about 10cm, and the depth is appropriate to not bury the heart.
Ranunculus japonicus is suitable for planting in sandy soil with good drainage and loose soil, and its pH value is 6-7.5.
Buttercups like to be wet, afraid of water, afraid of drought. During planting, do not lack water, but do not be too wet. At the same time, do not pour water on the leaf surface, otherwise it will cause disease.
Buttercup likes sunny environment and cool climate, but the temperature should not be lower than 10 ℃ or higher than 25 ℃.
Ranunculus japonicus is fond of fertilizer. It should pay attention to top dressing in the growing period. At the beginning, it should apply light fertilizer once every 10 days, and then gradually increase the dosage and concentration with the growth of flower seedlings.
Buttercups should not be exposed to strong light. The potted plants should be placed in a cool and shady environment to avoid drought, water logging and smoke pollution, and keep the potted soil and surrounding environment moist.
If the content of organic matter in basin soil is high, only one or two times of thin liquid fertilizer, mainly P-K fertilizer, is applied before and after budding.
Cut off the flowers at any time after flowering, apply liquid fertilizer once or twice to nourish the roots, and properly control the water to make them enter into the summer sleep safely.
If Ranunculus japonicus is planted in the courtyard, the plant row spacing is 15 cm to 20 cm. When potting, one ball can be planted in a small pot, and two balls can be planted in a large pot. Winter can be spent outdoors in warm areas, but indoors in cold areas.
The pot soil should be kept half dry to prevent the corm from rotting.
In spring, the soil should be kept moist, but in flowering, the soil should be slightly dry and applied with liquid fertilizer for 1-2 times. In summer, the soil should enter the dormancy period. After the ball root is collected, it should be fully dried and placed in a ventilated and dry place, otherwise it is easy to rot.
