Breeding methods of Palace Lantern Lilium

Seed reproduction and bulb reproduction are generally adopted.

The palace lantern lily is delicate in appearance, exquisite and lovely, the orange flower bell is matched with green and bright stems and leaves, it is very lovable, it is an excellent flower arrangement material and bride bouquet material, and has very high ornamental value.

Culture method of palace lantern lily

Palace lantern lily, also known as Christmas lily, Christmas wind bell, palace lantern flower, etc., is a perennial bulb herb of Liliaceae. It is named because its flower shape is similar to that of Chinese palace lanterns. It is native to eastern South Africa and usually grows on damp grasslands or forest margins. It has high ornamental value. Let's take a look at the breeding methods of palace lanterns.

Growth habits of Palace Lantern Lilium

Palace lantern lily originated in South Africa, wet and rainy in summer, is its growing season, dry and rainless in winter is its dormant period. Because the lantern lily is not strict on temperature and sunshine, it is very suitable for field and greenhouse cultivation in temperate and subtropical regions. The palace lantern lily is a temperate crop with good water permeability of the growth substrate and regular watering. The substrate should be disinfected regularly with fungicides, preferably in a well-ventilated greenhouse. The optimum soil temperature for growth is 15-22 ℃, and the optimum temperature for growth is 12-28 ℃.

Breeding methods of Palace Lantern Lilium

1. Sowing: the seeds of Gongdeng lily have deep dormancy mechanism, and the germination rate is very low. Gibberellin treatment can increase its germination rate by 20%. After a growing season, the seed can grow into a small bulb of 1 to 2 grams, and the bulb will take another 1 to 2 years to develop a commercial ball for cut flower cultivation.

2. Bulbs: when each bulb has two growing points, two new bulbs can be produced. The bulbs produced by this method are larger, but the reproduction rate is lower. The bulbs were planted in spring and germinated in 2-3 weeks when the ground temperature was higher than 16 ℃. If the climate is cold or dormant for less than 16 weeks, sprouting is recommended. Under the suitable environment, the plant can blossom in 45-60 days.

Culture method of palace lantern lily

1. Soil: choose loose and fertile soil with good drainage, and if the soil with low acidity is improved by quicklime, it can not only improve the soil, but also kill some soil germs and underground pests. If the alkaline soil is improved with phosphoric acid and peat, the dosage depends on the specific situation.

2. Fertilization: during soil preparation, Gongdeng lily was sprinkled with fully mature organic fertilizer, applying compound fertilizer 375600 kg / ha + organic fertilizer 30000 kg / ha or other mature organic fertilizer, which was evenly mixed in the topsoil 30 cm thick after being used as base fertilizer. In the plots where other bulb flowers have been planted, 800 times triclofenac should be added to prevent root mites. Do not need a high level of nutrition, generally do not apply fertilizer during the first three weeks of cultivation, during this period to ensure that the root system is well developed is the most important.

3. Temperature: the most suitable soil temperature during the growing period of Gongdeng lily is 18-24 ℃, and the temperature should be low in the first three weeks or at least before the stem takes root. When the temperature is higher than 20 ℃, it will lead to the decline of rooting quality, especially in summer, it is indispensable to keep or make the soil temperature cool. High temperature during the day will reduce the height of the plant, reduce the number of buds per flower, and produce blind flowers. Less than 15 ℃ at night will lead to bud drop, leaf yellowing and decrease of ornamental value.

4. Illumination: the lack of light in the palace lily is not conducive to the formation of flower buds, and too strong light will also affect the quality of cut flowers. Shading treatment and supplementary light measures should be carried out during the growth period to change the adverse effects of light factors on plant growth. Shading in the early growth stage is beneficial to improve the plant height, especially in summer, shading nets are used inside and around the greenhouse, so as not to cause excessive temperature in the greenhouse and cause damage to plants and buds. When the bud differentiation period to the bud growth is the leaf burning sensitive period, we should pay attention to the light and humidity changes should not be too large.

5. Moisture: Palace lantern lilies are easily affected by high salt, especially sodium salt, which will lead to water shortage. It is recommended to irrigate for 20-30 minutes a day from the 17th week after planting, and use electrical conductivity meter to detect soil electrical conductivity regularly. Watering from the top in the first 8 weeks after planting, changing the tee belt in the next 9 weeks, and stopping watering after 17 weeks of planting. Harvest the seed balls after stopping water for 4 or 6 weeks. When watering, you must pay attention to the amount of water, not more than 20 centimeters.

6. Ventilation: the temperature in spring, summer and autumn is guaranteed, and the temperature is higher at noon. The greenhouse film and top window can be opened in the morning to adjust humidity in a slightly lower temperature environment to avoid drastic changes in humidity in the high temperature stage. If the winter temperature is low, heat preservation measures should be taken. Ventilation should be carried out at noon when the outside temperature is high, and ventilation should be carried out intermittently.

7. Diseases and pests: the common diseases of Gongdeng lily are gray mold, leaf spot, root rot and so on, which are mainly controlled by planting balls and soil disinfection. During the growing period, fungicides such as Dysenamine and carbendazim can be sprayed alternately every 7-10 days. The common pests are mainly underground pests such as root mites and aphids, which are controlled by phoxim and triclofenac.

The propagation method of palace lantern lily the reproduction of palace lantern lily can use seed reproduction and seed ball reproduction. After pollination, each flower stem can bear 8-12 capsules, each capsule has about 50-70 seeds, because its seeds have deep dormancy mechanism, the germination rate is very low; gibberellin treatment can increase its germination rate by 20%. After germination, the seeds can grow into 1-2 grams of small bulbs after a growing season, and the bulbs can be developed into commercial balls for cut flower cultivation after 1-2 years. When Gongdeng lily propagates with seed ball, two new bulbs can be produced with two growing points in each bulb. the seed ball produced by this method is larger, but the reproduction rate is lower, and the secondary ball often grows in the growth and development of the bulb. the secondary ball is easy to break away from the ball during excavation or manual treatment, resulting in the loss of the growing point and germination ability of the ball. Because of the low multiplication rate of seed bulbs, seed reproduction is the main way to produce high quality bulbs in large quantities.
