Open field or greenhouse cultivation of lilies

  
Habits of many lily varieties are cultivated mostly ornamental artificial hybrids, mainly Asian lily, Lilium longiflorum and Lilium three kinds of lines. In recent years, most of the popular varieties of cut flowers from the Netherlands, Japan imported. Such as musk, lily, also known as Lilium, June-July flowering, plant height of 75-90 cm, leaves short and thick, 3-4 flower buds per plant, color white, trumpet-shaped, flowers and more, prices are high. Lilium longiflorum hi cool, wet environment, where plenty of sunlight, slightly shaded environment more suitable for Lily. Avoid dry, avoid heat, cold little worse more. Growth, flowering temperature of 16-24 ℃, below 30 ℃ 5 ℃ or higher than the growth almost stopped, 10 ℃ above normal plant growth was more than 25 ℃, the growth has stagnated, the winter temperature is below 5 ℃ last night 5-7 days, flower bud, flower bud development would be seriously affected, delayed flowering and even blind flower, flowers crack. Lilium longiflorum hi fertile, humus rich soil and more, very sensitive to hard clay; well drained slightly acidic soil is good soil pH 5.5 -6 * 5. Second, the breeding methods watched the ball lily breeding breeding, scales cuttings, seed propagation and tissue culture methods. Ball breeding: underground bulbs or near the ground internode many new scales on the president, let it grow up, take off the disk storage or directly planted. Usually planted for every ball after one year 1-3 students can be divided into small balls or more. Ball in the fall harvest with the Sand to the second spring planting, fall planting may also be the year in deep soil. Scales cuttings: the flowering of the mature stems cut into small pieces of dry bulb, or take off the scales buried in the sand, the insert 30 days from the axil between the bulbs grow, and then developed into a small bulb. Conducted in April-May planting, cutting depth to the top slightly exposed appropriate. Spring is generally 2-4 months after insertion, most scales can take root hair leaves grow small bulbs, then portable potted or planted in open field. Seed propagation: seeds before planting on the light before the seeds are taken out for embryo development to enrich planting, germination temperature for 12-15 ℃, 15 ℃ or more seeds germinate faster, but the seedlings thin, less than 5 ℃ not germinate; 25 ℃ above the seed dormancy do not germinate. Spring and autumn can be planted, the casing after sowing, 0.5 cm -1, about 20-30 emperor leaves unearthed. Spring seedlings, planted in autumn, after 2-3 years after flowering. Tissue culture: the use of different parts of the lily, such as filaments, style, ovary, scales at the base of the buds into a tissue culture plantlets and transplant care in seedbed grew up, for the production of bulbs. Third, the cultivation techniques 1, fertilizer and water management: musk, lily warmer areas in southern China could open field cultivation, or potted plants, greenhouses, etc..
Open field or greenhouse cultivation of lilies, planted should choose weather the cold, moist air and semi-shade environment, very sensitive to cropping, the planting is better to choose a new earth. Fertile, good ventilation, deep sandy loam soil. 1-2 times in the kinds of deep plowing before, Shizujifei, Mushi-quality manure composting 2500-3000 kg, 50 kg groundnut cake, bone meal 25 kg, ash 200 kg, phosphate and potash of 30 kg, 30 cm deep plowing, crushing , loose soil, the whole into a ridge of high 20-25 cm, 80 cm wide ridge, ridge bottom width 30-40 cm, Goushen 25 cm. Before planting for soil disinfection. Lilies planted in open field suitable period of August-September. Plants should be in September-October. Pot culture soil with leaf mold, coarse sand, garden soil at 3:2:5 ratio mixture, the amount can be applied to ash, humic droppings, pigeon feces, Crotalaria, or 3-5 grams of fertilizer applied. Exposed to a large ball species, planting depth of 12 cm, spacing of 10-15 cm × 20 cm, the soil should be kept moist after planting, 20-30-day shoots ground-breaking. Plant pots with coarse sand or cinder block bottom bedding for 3-4 cm thick drainage layer, to use the deep basin, basin diameter 20-25 cm pots will be available for 2-3 balls. As pot plants or container plants placed under cool environmental management, can also be used to avoid sun shading to direct sunlight or straw mat, and proper watering, dry as wet appropriate. Spring and summer drought or high temperature and drought, to prevent the laying of straw dry, keep the soil moist, Qigou 1-2 times or spray irrigation should be a permeable. Seedlings and cut flowers after the appropriate water control, anti-soil temperature is too low and leaving more water bulb rot. Attention to ventilation, the seedling growth robust. Hot autumn season, every day at noon to foliar spray 2-3 times to prevent the soil temperature exceeds 30 ℃ to affect growth. 20 days after transplanting fertilizer 2-3 times. Applied once every 15 days growth period to maturity of peanut cake liquid fertilizer is appropriate, or applied synthetic fertilizer or urea per 100 square meters 1-1 * 5 kg potassium hydroxide - magnesium sulfate 1-2 kg. After flowering in 2-3 months and applied to the synthesis of fat, avoid fluoride and alkaline fertilizer applied, or prone to burning leaves. If it is found iron deficiency phenomenon, should be sprayed 0.2% -0.8 3% ferrous sulfate solution. Squaring to flowering, spray every 15 days 0.2% -0.8 a 3% potassium dihydrogen phosphate solution, cut flowers after 1-2 times rich in phosphorus and potassium fertilizer quick fat. Between plants from February to July, applied once every 2 months, fertilizer, fertilizer plants and exposed the same. Plate diameter 20 cm, plate use about 5 grams applied to light after the plate loose soil, the fertilizer mixed with soil plate. Available over the rice washing water retting facilities watered roots, but also applied 0.1 urea, liquid fertilizer flower-specific, applied two times per month. Winter temperatures dropped to 5-8 ℃ monthly Shi 1, less than 5 ℃ to stop fertilization to be the temperature rise Zaishi. Late February to early March 8-10 at the plate side of topsoil applied grams superphosphate or bone meal. Squaring to flowering applied 2 times a month 0.2% potassium dihydrogen phosphate, a small amount of borax, magnesium nitrate, etc., or flowers, specialty fertilizer applied strong root spikelet, flowering should not be applied after flowering can be applied two times per month nutritional thin liquid fertilizer can be Paul green stems and leaves, bulbs and promote new growth underground.
