Planting techniques of palace lantern lily: propagation skills, cultivation points and pest control

Palace lantern lily (Sandersonia aurantiaca) alias lantern lily, Liliaceae palace lantern lily. Originally from South Africa. The environment is warm in winter and cool in summer and sunny. It is not cold-resistant, the suitable temperature for growth is 1824 ℃, and the winter temperature is not lower than 5 ℃. Afraid of strong light and drought, avoid stagnant water, fear extreme heat. Suitable for fertile, loose loam.

Reproductive skills: 1. Sowing: the seeds are sown immediately after maturity, often sown in indoor pots, and the suitable temperature for germination is 1824 ℃. two。 Ramet: in autumn or winter, the roots are dug up and cut into small pieces with new buds, stored in the room or potted.

Cultivation points: potted with 15-20 cm pot, each pot with a section of rhizome, pot soil with rotten leaf soil or peat soil. Keep the basin soil moist after sprouting and emergence, fertilize once a month during the growing period, use rotten cake fertilizer and water or Huiyou 20-20-20 general fertilizer. It usually blossoms for about 2 months, and retaining some leaves after flower fade is beneficial to promote the development of root tubers. The leaves naturally withered and yellow entered the dormant period, so watering should be reduced.

Pest control: common standing blight and white silk disease harm, the initial stage of the disease with 50% methyl parathion wettable powder 800 times liquid spray. Pests include aphids, which are sprayed with 1500 times of imidacloprid wettable powder when they occur.

Cultivation techniques of Palace Lantern Lilium

Palace lantern lily is a bulb flower of Liliaceae, which is named because its flower shape and color is very similar to that of Chinese palace lantern. When it blossoms, it is like a string of lanterns hanging on the flower branches, setting off the green leaves. It is called Christmasbells in English because its florescence is at Christmas.

Growth habit

Palace lantern lily originated in South Africa, wet and rainy in summer, is its growing season, dry and rainless in winter, for its dormant period. Because the palace lantern lily is not very strict on temperature and sunshine, it is very suitable for greenhouse and field cultivation in temperate and subtropical regions.

The most suitable soil temperature for palace lantern lily is 18 ℃-24 ℃, which is best cultivated in greenhouse with rain shelter and shade facilities. If the temperature is higher than 30 ℃, the growth will be inhibited and the flower stem will be twisted. When planted in summer, high temperature shortens the growth period, flowering in less than 45 days, and the flower stem is also shortened. Normally, the palace lantern lily blossoms 60 days after planting. In winter, the low temperature period is longer and the temperature is not too high to affect the growth of the lily in northern Taiwan or middle altitude, so the cut flower quality is good and the bulb yield is high, while in summer, the growing period of the lily is shorter because of the long high temperature period. it is not conducive to cut flowers and bulb production.

Cultivation and management

Soil and fertilization choose loose, fertile and well-drained soil. If the soil with low acidity is improved with quicklime, it can not only improve the soil, but also kill some germs in the soil and underground pests. If the alkaline soil is improved with phosphoric acid and peat, the dosage depends on the specific situation. During soil preparation, fully mature organic fertilizer was sprinkled, and compound fertilizer 375-600kg per mu was applied with 30000kg/hm2 + organic fertilizer, or other mature organic fertilizer, which was evenly mixed in the topsoil 30cm thickness 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. Lilies do not need a high level of nutrition and generally do not apply fertilizer during the first three weeks of cultivation, during which it is most important to ensure good root development. For small bulbs, fertilizer containing humic acid and some trace elements can be sprayed when the seedling height is 10-30cm in the early growth stage, so as to increase stress resistance and promote rooting. Before the seedling height 30cm, the soil topdressing was not carried out before the stem root length reached 5cm. Calcium nitrate 75kg/hm2 or compound fertilizer 150kg/hm2 can be applied once after stem rooting. If the plant growth is not strong enough due to the lack of nitrogen fertilizer during the growth period, 20-150kg/hm2 of available nitrogen fertilizer can be applied. Soil topdressing should be 2-3 times, and foliar topdressing can be done once a week. Spray the plant with water after topdressing to prevent leaf burning.

Temperature management and control of ground temperature is the key to early management. 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. Cool down through ventilation, spray and shading in summer, and pay attention to heating and heat preservation in winter.

The air temperature in spring, summer and autumn is guaranteed, and the noon temperature is relatively high, so the greenhouse film and the top window can be opened in the morning, and the humidity can be adjusted 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, and ventilation should be carried out intermittently when the outside temperature is high at noon.

Lack of light management is not conducive to the formation of flower buds, too strong light will also affect the quality of cut flowers. generally speaking, shading treatment and light supplement measures are needed 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 outside the greenhouse 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.

The common diseases of pest control are gray mold, leaf spot, root rot and so on, which are mainly controlled by seed ball and soil disinfection. During the growing period, the disease can be sprayed alternately every 7-10 days, such as carbendazim and other fungicides. The common pests are mainly underground pests such as root mites and aphids, which are controlled by phoxim and triclofenac.

Cut flowers can be harvested when the three flowers in the lowest part of the stem are golden, usually leaving 2-3 leaves at the base of the plant. The harvested cut flowers should be timely put into clear water for more than 2 hours, and then put into the fresh-keeping solution, placed in a cold room of 6 ℃-8 ℃, and packed in stages after 4-6 hours.
