How to breed perfume lily;
There are many breeding methods of perfume lily, and the following are the main ones.
1. Bulb propagation: there are few bulbs, so it cannot be used as the main propagation method, but it can be used.
2, bead propagation: purple and black beads similar to small bulbs can be used for propagation.
3. Seed propagation: Lily seeds are divided into fast hair type and slow hair type. The germination of slow-growing seeds goes through the processes of storage, rooting, bulb growth and flowering, while the process of fast-growing seeds is relatively shortened.
4. Cutting propagation: The stems and leaves near the ground of lily can regrow in water or wet soil.
How to raise perfume lilies;
1, soil: perfume lily likes fertile soil with deep humus and hates hard clay most; The slightly acidic soil with good drainage is better, and the soil pH value is 5.5 ~ 6.5.
2, watering: watering only needs to keep the pot soil wet, the pot soil can not be too wet, otherwise the bulbs will rot easily.
3. Illumination: Different growth stages of potted lily require different light intensity, and shading treatment is needed in bud stage, and appropriate shading is needed when the leaf temperature is too high. In other growth stages, light should be strengthened, especially in the flower development stage: the flowering temperature of perfume lily is 16 ~ 24℃, and the growth almost stops below 5℃ or above 30℃, which is 65438+. When the temperature exceeds 25℃, the growth will stop again. If the temperature is lower than 5℃ for 5 ~ 7 consecutive days in winter night, the differentiation and development of flower buds will be seriously affected, and flowering will be delayed or even blind.
4. Fertilization: Lily needs a lot of nitrogen and potassium fertilizer, which should be applied every 10 ~ 15 days during the growing period, but the supply of phosphate fertilizer should be limited, because too much phosphate fertilizer will lead to yellowing of leaves. (65438+ 0 ~ 2 days phosphate fertilizer can be added at flowering stage)
5, pests and diseases:
(1) Botrytis cinerea: Control with 500 times of clonidine, Tobuzin and zineb solution.
(2) Rhizoctonia solani: Before planting hot farmers, soak in 500 times formalin solution or 50 times 40% formaldehyde solution 15.
(3) Root rot: The diseased plants need to be removed and then disinfected with Dixon soil.
(4) Use omethoate, dicofol and poison bait to control aphids, mites, grubs, cutworms and other pests.
6. Pruning: In order to enrich the bulbs, the lily after flowering can be cut off on the same root to reduce nutrient consumption, because flowering has consumed a lot of nutrients in the bulbs. If you want to keep the bulbs, you should continue to fertilize and supplement the nutrients in the bulbs. After a month, you can dig out the bulbs, cut the fibrous roots, put them in the refrigerator for a while, break the dormancy, and plant them later, but the quality of the flowers will decline.
Matters needing attention in raising perfume lily:
1, flowering regulation: If the perfume lily blooms in early February of the following year 1 1. Bulbs treated at 13℃ for 2 weeks (14 days) and then at 3℃ for 45 weeks (2836 days) can bloom in1165438+February. If it is required to bloom in 65438+February, it can be treated at 13℃ for 2 weeks and 8℃ for 45 weeks (2836 days). At this time, the temperature at night after planting is low and should be kept at 15℃.
2. Bud elimination treatment: When the flower buds grow to 12 cm in lily cultivation, bud elimination is easy to occur due to insufficient light. Bud elimination usually occurs from the end of 10 to the middle of March of the following year, which can be supplemented by artificial lighting. The method is to hang a 40-watt high-pressure sodium lamp or ordinary waterproof incandescent lamp every 8 10 square meter, and the light supplement period starts from 0.5 1 cm before flower bud and lasts until harvest. At the temperature of 65438 06℃, it is very effective to keep the light for about 6 weeks at 8:00 ~ 4:00 pm in Rosty Yi area to prevent flower buds from withering, blossom early and improve the quality of cut flowers.
3, the plant is too long: perfume lily should turn over the flowerpot once a week during the growing period. Otherwise, plants tend to grow tall and affect their appearance.
