Propagation methods of water lilies

Water lilies are mainly propagated by individual plants, and they can also be sown.

The method of propagation of water lilies: separate propagation

When ramet, the cold-tolerant species are usually carried out 2-4 months before germination in early spring, and the cold-tolerant water lilies have high requirements for air temperature and water temperature, so they can not be carried out until around the middle of May. When ramet, the rhizome of water lily was dug out, and the rhizome with full new buds was selected and cut into 8: 10 cm long, with at least one bud in each segment, and then planted. The top bud of water lily was buried in the topsoil with the top bud facing upward, and the suitable depth of covering soil was that the bud eye of the plant was flat with the soil surface, and each pot was planted in 5-7 segments.

Breeding methods of water lilies:

Ramet propagation

Water lilies are mainly propagated by ramets. Cold-tolerant species usually split from March to April before germination in early spring, and cold-tolerant species have high requirements for air temperature and water temperature, so they can not be divided until around the middle of May. When ramet, first dig out the rhizome, select the rhizome with full new buds, cut into 8~10cm-long root segments, each segment with at least one bud, and then plant. The terminal bud is buried upward in the topsoil, and the depth of the covered soil is that the bud eye of the plant is flat with the soil surface, and each pot is planted in 5-7 segments. After planting, a little sun, can be injected into shallow water, in order to maintain the temperature of the water, but irrigation should not be too deep, otherwise it will affect germination. The water level will be deepened when the temperature rises and new buds sprout. Put it in a well-ventilated and sunny place for maintenance, the cultivation water depth is 20~40cm, the summer water level can be properly deepened, and attention should be paid to keeping the basin water clean in high temperature season. In a small number of potted plants, the water lilies that have been planted for 2-5 years can be poured out of the pot, cut into 2-4 pieces, and then planted in the pot.

Sowing and reproduction

Water lilies can also be sowed and propagated, that is, they are transferred to water after blooming, and before the fruit is ripe, the flowers are wrapped in gauze bags so that the seeds fall into the bag after the fruit is broken. After harvesting, the seeds must still be stored in water, such as dry storage will lose the ability to germinate. Sowing in March-April, the basin soil should not be too full with fertile clayey loam, it is appropriate to leave the basin mouth 5~6cm, sow the seeds and cover the soil 1cm, press and soak into the water, the water surface is higher than the basin soil 3~4cm, cover the basin soil with glass, put it in the sunny warm place, in order to increase the temperature in the basin. The suitable sowing temperature is 25: 30 ℃. After about half a month, it can blossom in the second year.

This is the end of the breeding method of water lilies. Water lilies are among the most valuable aquatic flowers. The appearance is similar to that of the lotus, except that the leaves and flowers of the lotus protrude to the surface, while the leaves and flowers of the water lily float on the surface. Water lilies are known as "sleeping beauties in flowers" because they roll day and night.

Culture methods of water lilies

Propagation methods of water lily seeds

The seeds are poured into a container filled with water and placed in 25 ℃-30 ℃ warm water to accelerate germination. The seeds can germinate in about 2 weeks by changing water every day. When the seedlings grow young roots, they are moved into small pots for planting. After planting, put the small basin into the water tank with a water depth of 1 cm to submerge the young leaves. When the temperature rises to 17 ℃ in April, it can be moved to open-air culture. Change the basin 2-3 times with the growth of the new leaf, and finally plant it in the jar or basin whose diameter is not larger than 35cm.

Pot method of Rhizome

Potted plants can be planted in pots or pots with an inner diameter of 40 cm and a depth of about 60 cm from the end of March to the beginning of April.

When planting, the river mud of 3-4 cm is now placed at the bottom of the pot, and the filling should not be excessive. Usually, 20-25 cm of water injection space should be left in the upper part, and then the top bud of the cut rhizome should be buried upward under the soil surface, and then slightly increase the cover of the soil. the depth of covering soil should be flush with the top bud, with 5-7 sections per pot.

When just planting, do not inject water too deeply, it is appropriate to 2-3 cm, in order to improve the water temperature, and then put the pot in a well-ventilated, sunny place for maintenance. After that, the water level gradually deepened with the growth of the plant.

Summer irrigation depth of about 25-35 cm is appropriate, and often maintain this depth. Remove the residual flowers and withered leaves in time after flowering to prevent the consumption of nutrients and keep them clean and beautiful. 2-3 times of fertilizer should be added during the growth period.

Pour the water out of the basin before the cold dew festival to prevent overwintering in a cold room of about 3 ℃ and keep the basin soil moist without freezing. The Spring Equinox combined with changing the basin and soil before and after applying appropriate amount of rotten bean cake juice as base fertilizer.

Daily management and maintenance

Water lilies belong to long sunshine plants, the planting place should be well lit and well ventilated. Water lilies have different requirements for water level at different growth stages.

The initial water level is slightly below the edge of the basin, and gradually increases with the growth of the leaves. In the early growth stage of potted water lilies, the base fertilizer should be sufficient, there is no need to topdressing, and quick-acting potassium dihydrogen phosphate should be applied at flowering stage.

Matters needing attention

Attention should be paid to the removal of weeds, withered leaves and surface algae throughout the growing season. Too much algae, can spray 0.3-0.5% of the solution, once every half a month, several times in a row can play a certain control role.
